PurposeTo investigate the effect of host immunity (allospecific) and surgical
manipulation (non-allospecific) on corneal endothelial cells (CECs) in corneal
transplantation.MethodsDraining lymph nodes and grafted C57BL/6 corneas were
harvested from syngeneic recipients, allograft acceptors, and allograft rejectors
(BALB/c) 1, 3, and 8 weeks after transplantation. We analyzed CEC apoptosis using
an ex vivo cornea-in-the-cup assay, and visualized cell-to-cell junctions using
immunohistochemical staining (ZO-1). Automatic cell analysis using Confoscan
software was used to measure CEC density as well as changes in CEC morphology by 
quantifying the coefficient of variation in cell size (polymegethism) and shape
(pleomorphism).ResultsThe cornea-in-the-cup assay showed that allogeneic acceptor
T cells and to an even greater extent rejector T cells (but not syngeneic T
cells) induced CEC apoptosis. CEC density after corneal transplantation was
significantly reduced in allogeneic acceptors compared with syngeneic grafts
(P<0.001), and CEC density was even further reduced in the allo-rejector group
compared with the allo-acceptor group. Allogeneic grafts showed a greater
increase in the coefficient of variation in cell size (polymegethism) when
compared with syngeneic grafts 1 week after transplantation (P=P<0.001). However,
pleomorphism was not significantly different between syngeneic and allo-acceptor 
grafts, indicating that polymegethism (but not pleomorphism or cell density) is a
sensitive indicator of the effect of alloimmunity on CECs.ConclusionsOur data
demonstrate that host alloimmunity rather than surgical manipulation alone is the
major cause of CEC damage in corneal transplantation, and such morphologic
changes of CECs can be detected before the clinically visible onset of allograft 
rejection.Eye advance online publication, 17 October 2014;

New understanding on the contribution of the central otolithic system to eye
movement and skew deviation.

University of Toronto, and the Toronto Western Hospital, Toronto, Canada.

The otolith organs consist of the utricle and saccule. The utricle mediates the
utriculo-ocular reflex by detecting horizontal head translation and static head
tilt. Skew deviation is a vertical strabismus caused by imbalance of the
utriculo-ocular reflex pathway and is commonly caused by lesions in the brainstem
or cerebellum. It is associated with abnormal utriculo-ocular reflexes including 
asymmetric reduction of the translational vestibulo-ocular and ocular counterroll
responses. Skew deviation is also associated with head position-dependent changes
in ocular torsion and vertical strabismus. The reduction in ocular torsion and
vertical strabismus when changing from an upright to supine position in skew
deviation allows us to devise a new bedside 'upright-supine test' to
differentiate skew deviation from fourth nerve palsy and other causes of vertical
strabismus.Eye advance online publication, 17 October 2014;

ObjectiveTo develop a tool for assessing amblyopic risk and monitoring the
treatment effect of propranolol in periocular haemangioma management.MethodsWe
present a study of nine children with periocular haemangioma who underwent
propranolol treatment at York Hospital between 2009 and 2013.A proposed measure
of amblyogenic risk based on the induced anisometropia resulting from a
periocular haemangioma was calculated in the form of a single quantitative value,
measured in dioptres. This calculation used published work and developed it to
produce a new function, termed the delta defocus equivalent (DFE-∂).Refraction
measurements were retrospectively collected from patients' notes in order to
measure the trend of DFE-∂ over the treatment period with propranolol.ResultsThe 
average DFE-∂ at commencement of propranolol was 1.54 (±0.62) D. The average at
the end of treatment was 0.39 (±0.38) D.ConclusionThis work presents a possible
tool for assessing amblyopic risk in cases of periocular infantile haemangioma.
The DFE-∂ gives a measure in dioptres, which may represent the true amblyopic
risk, and so be useful in supporting treatment decisions in paediatric
ophthalmology.Eye advance online publication, 17 October 2014;

PurposeTo evaluate the long-term clinical efficacy and safety of gas tamponade
combined with laser photocoagulation for optic disc pit maculopathy.MethodsSeven 
consecutive patients with unilateral maculopathy associated with optic disc pit
and one patient with bilateral optic disc pit maculopathy were given
octafluoropropane (C3F8) tamponade combined with focal laser photocoagulation
treatment. Patients were followed up for 21-62 months after treatment. Main
outcomes were determined by optical coherence tomography (OCT) and best-corrected
visual acuity (BCVA).ResultsTreatment with C3F8 tamponade followed by laser
photocoagulation in ODP maculopathy patients resulted in resolution of
sub-retinal and/or intra-retinal fluid in six out of eight patients. The
remaining two patients had significant reduction in fluid, as determined by OCT, 
and funduscopy, as well as an improvement in anatomical architecture. Visual
acuity improved obviously in seven eyes and remained stable in two eyes. Central 
visual field loss after photocoagulation was not clinically appreciable by visual
field examination. No post-operative complications of maculopathy occurred during
the follow-up period.ConclusionsAlthough repeated treatment was needed in some
patients, C3F8 tamponade combined with laser photocoagulation is still a simple, 
effective, minimally invasive, and economic therapy for optic disc pit
maculopathy.Eye advance online publication, 17 October 2014;

Medicine, University of Leeds, Leeds, UK [2] Glasgow Centre for Ophthalmic
Research, Tennent Institute of Ophthalmology, NHS Greater Glasgow and Clyde,
Glasgow, UK.

Familial exudative vitreoretinopathy (FEVR) is a rare inherited disorder of
retinal angiogenesis. Cases can be autosomal dominant, autosomal recessive, or
X-linked. FEVR patients have an avascular peripheral retina which, depending on
the degree of ischaemia, causes the secondary complications of the disease.
Expressivity may be asymmetric and is highly variable. Five genes have been
identified that when mutated, cause FEVR; NDP (X-linked), FZD4 (autosomal
dominant and recessive), LRP5 (autosomal dominant and recessive), TSPAN12
(autosomal dominant and recessive), and ZNF408 (autosomal dominant). Four of
these genes have been shown to have a central role in Norrin/Frizzled4
signalling, suggesting a critical role for this pathway in retinal angiogenesis. 
In addition to the ocular features, LRP5 mutations can cause osteopenia and
osteoporosis. All FEVR patients in whom molecular testing is not easily
accessible should have dual energy X-ray absorptiometry (DEXA) scans to assess
bone mineral density, as treatment can be initiated to reduce the risk of bone
fractures.Eye advance online publication, 17 October 2014;

University, Shanghai, People's Republic of China.

PurposeTo evaluate the effect of pupil size on higher-order aberrations (HOAs) in
high-myopic pseudophakic eyes with posterior staphyloma using KR-1W
aberrometer.MethodsForty eyes of 40 high-myopic cataract patients with posterior 
staphyloma and 20 eyes of 20 age-related cataract patients with normal axial
length were recruited. At 1 month after phacoemulsification and intraocular lens 
implantation, ocular and internal HOAs as well as the visual quality data in the 
two groups were evaluated with KR-1W analyzer before and after
mydriasis.ResultsCompared with normal axial length eyes, high-myopic pseudophakic
eyes with posterior staphyloma had significantly lower values of internal coma
both under 4-mm and 6-mm pupil sizes (P<0.001 and 0.020), as well as internal
total HOAs (P<0.001) and third-order aberrations at 6-mm pupil size (P=0.018).
Statistically significant differences were also found in the variation from 4- to
6-mm pupil sizes for internal coma (P=0.001), internal third-order aberrations
(P=0.009), internal total HOAs (P=0.007), and ocular coma aberrations (P=0.006)
between two groups. After mydriasis, Strehl ratio increased significantly in
high-myopic eyes, whereas decreased slightly in normal axial length eyes (P=0.032
when compared with the variation between the two groups). Statistically
significant differences were also found for the variation of modulation transfer 
functions (MTFs) at frequencies of 15, 30, 45, and 60 cycles/degree between the
two groups (P=0.002, 0.002, 0.004, and 0.010,
respectively).ConclusionsHigh-myopic pseudophakic eyes with posterior staphyloma 
had significantly lower internal coma and less coma variations during
mydriasis.Eye advance online publication, 17 October 2014;

PurposeDue to high genetic heterogeneity, to exclude known mutations and map
novel mutations in autosomal dominant congenital cataract (ADCC) using
conventional candidate gene screening requires laborious laboratory work. We
attempted to use a cost-effective exome sequencing strategy to identify
disease-causing mutations in an ADCC pedigree.MethodsAn ADCC pedigree affected by
nuclear cataract and 200 unrelated senile cataract controls were recruited and
given comprehensive ophthalmic examination. Whole exome of the proband of the
family was captured by the Illumina TruSeq Exome Enrichment Kit, followed by
sequencing using Illumina HiSeq 2000 sequencer. Validation was performed by
direct sequencing.ResultsThe whole exome, including all exons of known ADCC
disease-causing genes, was screened for possible disease-causing mutations. A
recurrent missense mutation c.773C>T (p.S258F) in exon 2 of the gap junction
protein alpha 8 gene (GJA8) was identified in the proband with nuclear cataract. 
The result was confirmed by direct sequencing. The mutation showed complete
co-segregation with the disease phenotype in the family but was not observed in
unrelated unaffected controls.ConclusionBy successfully sequencing whole exome of
only one proband and identifying a GJA8 mutation in one ADCC pedigree, the
current study demonstrated that exome sequencing could serve as a rapid, robust, 
and cost-effective approach in clinical diagnosis and disease-causing gene
discovery for ADCC.Eye advance online publication, 10 October 2014;

AimTo describe the parafoveal cone arrangement in emmetropic subjects and its
variations with eccentricity, meridians and change in axial length in Indian
eyes.MethodsWe imaged 25 subjects using compact adaptive optics (AO) retinal
camera prototype, the rtx1. Imaging was done at 1, 2, and 3° eccentricity from
the fovea in four meridians: nasal, temporal, superior, and inferior.ResultsA
statistically significant drop in the cone packing density was observed from 2 to
3° (2° eccentricity=25 350/mm(2) (5300/mm(2), 8400-34 800/mm(2)) 3°
eccentricity=20 750/mm(2) (6000 mm(2), 9000-33 670/mm(2))) P<0.05. The spacing
correspondingly increased with increase in distance from the fovea (2°
eccentricity=6.9 μm (0.70 μm, 5.95-11.6 μm)) and 3°eccentricity=7.80 μm (1.00 μm,
6.5-13.5 μm) P<0.05. As the axial length increases, the cone density
significantly decreases. Interocular variations were noted.ConclusionWith the
advent of AO, visualization at the cellular level is now possible. Understanding 
the photoreceptor mosaic in the parafoveal space in terms of its density,
spacing, and arrangement is crucial so as to detect early pathology and intervene
appropriately. Newer therapeutic modalitites that are targeted at the cellular
level like yellow micropulse laser, stem cells, gene therapy and so on may be
better monitored in terms of safety and efficacy.Eye advance online publication,

PurposeTo determine the genetic association of an inflammation-related gene,
formyl peptide receptor 1 (FPR1), in exudative age-related macular degeneration
(AMD) and polypoidal choroidal vasculopathy (PCV).MethodsThe coding region of
FPR1 gene was sequenced in 554 unrelated Chinese individuals: 155 exudative AMD
patients, 179 PCV patients, and 220 controls. Interactions and combined effects
of FPR1 with complement factor H (CFH), high temperature requirement factor A1
(HTRA1), and smoking were also investigated.ResultsA total of 28 polymorphisms in
FPR1 were identified. Single nucleotide polymorphisms (SNP) rs78488639 increased 
the risk to exudative AMD (P=0.043) and PCV (P=0.016), whereas SNP rs867229
decreased the risk to exudative AMD (P=0.0026), but not PCV. Homozygous G allele 
of rs1042229 was associated with exudative AMD (P=0.0394, odds ratio (OR)=2.27,
95% confident interval: 1.08-4.74), but not with PCV. Exudative AMD, but not PCV,
was associated with the heterozygous genotypes of rs2070746 (P=0.019, OR=0.57)
and rs867229 (P=0.0082, OR=0.54). Significantly, interactions were identified
among FPR1 rs78488639, CFH rs800292, and HTRA1 rs11200638 in both exudative AMD
and PCV. Combined heterozygous risk alleles of CFH rs800292 GA and FPR1
rs78488639 CA were posed to PCV (P=2.22 × 10(-4), OR=10.47), but not exudative
AMD. Furthermore, FPR1 rs78488639 CA combining with HTRA1 rs11200638 and smoking 
was also predisposed risks to exudative AMD and PCV.ConclusionFPR1 is associated 
with exudative AMD and PCV in a Hong Kong Chinese cohort. FPR1 rs78488639
interacted with CFH rs800292, HTRA1 rs11200638, and smoking, enhancing risk to
exudative AMD and PCV.Eye advance online publication, 3 October 2014;

PurposeTo characterise the history, clinical and histopathological features of
patients with bilateral nasal and temporal peripheral hypertrophic subepithelial 
corneal degeneration in a German population.MethodsA detailed ophthalmological
and dermatological history and clinical findings were recorded of nine patients
with bilateral simultaneous nasal and temporal peripheral corneal degeneration
from two centers in Germany. Excised tissues were studied by histopathology,
immunohistochemistry, and transmission electron microscopy.ResultsForeign body
sensation and need of artificial tear substitutes were the only symptoms reported
regularly. Schirmer's and Jones-test were normal in all, but fluorescein break-up
time of >10 s was found in five eyes of four patients. Best corrected visual
acuity was reduced only under glare conditions. Corneal topography revealed
irregular astigmatism in 13 of 14 eyes. Follow-up median time was 35 months. Most
cases were stable within the follow-up period. Light and electron microscopy
revealed the findings of superficial vascularised corneal hypertrophic scars,
oxytatlan fibers, and discontinued Bowmans layer.ConclusionIn this series of
German patients with peripheral hypertrophic subepithelial corneal degeneration, 
the changes were predominantly located in the palpebral aperture and often
present in both eyes. No associated surface disease could be established in this 
study. Light and transmission electron microscopy showed histological features
that are similar to Salzmann's corneal changes without any inflammation. We
hypothesise that light exposure and a localised limbal insufficiency could be
involved in the pathogenesis.Eye advance online publication, 3 October 2014;

Summary statementIntravitreal high dose (2 mg) ranibizumab may lead to quicker
resolution of choroidal neovascularization (CNV) and associated retinal pigment
epithelial detachment in eyes with exudative age-related macular degeneration,
although it may possibly correlate with RPE tears in certain cases.PurposeThis
prospective study compared the outcomes of 0.5 vs 2.0 mg intravitreal ranibizumab
injections (RI) for treating vascularized pigment epithelial detachment (vPED)
due to age-related macular degeneration.MethodsPatients with vPED were randomized
to receive 2.0 vs 0.5 mg RI monthly for 12 months or for 4 months and then
repeated on a pro-re nata basis. Optical coherence tomography, fundus
photography, and fluorescein and indocyanine-green angiography were obtained at
baseline and subsequent specific intervals. Outcome measures were best-corrected 
standardized visual acuities, central 1-mm thickness, surface area (SA), greatest
linear diameter (GLD), heights (PED and CNV), and amount of subretinal fluid
(SRF) and cystoid macular edema (CME).ResultsBoth groups yielded reductions of
the central 1-mm thickness, PED and CNV SA and PED height and GLD, SRF, and CME. 
Vision improvement and reduction in SRF and PED height occurred earlier for eyes 
receiving the 2.0 mg dose. Cataract progression was similar but RPE tears
developed more often with the 2.0 mg dose.ConclusionsThere were similar visual
and anatomical outcomes at the end of the study; however, the higher dose yielded
more rapid reductions and more complete resolution of the PED, although there was
possible increased tendency for an RPE tear with the higher dose.Eye advance

Background and aimsWe aimed to evaluate the association of subfoveal choroidal
thickness (SFCT) with age and to determine its relationship with axial length
(AL) and ocular biometric parameters, in children and young adults during growth 
period.MethodsOne hundred and sixty patients (80 male, 80 female) aged between 4 
and 23 years were included. Patients were classified into five groups according
to their ages as group 1 (4-7 years of age), group 2 (8-11 years), group 3 (12-15
years), group 4 (16-19 years), and group 5 (20-23 years). SFCT was assessed using
spectral-domain optical coherence tomography (3D OCT-2000). The measurements were
taken at the same daytime (1000-1200 hours) to avoid diurnal fluctuation. Ocular 
AL and anterior segment parameters were measured using optical biometry (Lenstar 
LS900)).ResultsThe average SFCT was 308.1±47.6 μm, ranging from 206 to 410 μm.
The mean SFCT values in group 1 to 5 were measured as 306.8±42.0, 297.8±48.1,
283.2±38.9, 326.9±57.4, and 325.8±35.9 μm, respectively. The mean CT of group 3
was significantly thinner than group 4 and 5 (P<0.05 for two groups), however,
there was no statistical significance compared with group 1 (P=0.227) and group 2
(P=0.693). On stepwise regression analysis, age exhibited a positive association 
with SFCT (B=2.8, P<0.001) and AL exhibited a negative association with choroidal
thickness (B=-16.7, P<0.001).ConclusionsWe found that SFCT shows no age-related
difference until age of 15, whereas 16-23-year old participants had thicker SFCT 
compared with the younger ones. In that aspect, a thicker choroid associated with
age in certain age groups suggests an age period of SFCT increase to a plateau in
young adulthood. Larger studies are warranted to elucidate the age-related
changes in SFCT in childhood, as improved evaluation of normal choroidal
thicknesses during eye growth should assist in the diagnosis of choroidal
abnormalities associated with eye disease.Eye advance online publication, 3

Author information: 
Department of Ophthalmology, University Hospital Aintree, Liverpool, UK.

PurposeTo compare choroidal thickness in patients with regressed retinopathy of
prematurity (ROP) with healthy controls using enhanced depth imaging optical
coherence tomography (EDI OCT)MethodsTwenty-four children and young adults (41
eyes) with regressed ROP≥stage 3 had undergone EDI OCT with Spectralis FD-OCT as 
part of their clinical record. Their refraction, best-corrected visual acuity,
and ophthalmoscopic findings were recorded. Corresponding data was collected
prospectively from 33 healthy controls (58 eyes) who had been born at term.
Choroidal thickness was measured independently by two observers subfoveally and
at 1500 μm nasal and temporal to the fovea using EDI OCT.ResultsMean subfoveal
choroidal thickness, adjusted for refraction, was 271.1 μm (95% CI, 247.8-294.5) 
in the ex-ROP group, which was significantly thinner than 327.4 μm (95% CI,
293.8-360.9) in controls (P=0.008). Similarly, mean adjusted temporal choroidal
thickness was 257.2 μm (95% CI, 240.2-274.2) in ex-ROP's vs 320.5 μm (95% CI,
288.6-352.3) in controls (P=0.001). There was no statistically significant
difference in the nasal measurement. In the ex-ROP group, there was no
significant correlation between subfoveal choroidal thickness and gestational age
(rs=0.16, P=0.46) or birthweight (rs=0.03, P=0.90). In eyes without copathology
in addition to regressed ROP (29 eyes, 19 patients), there was no significant
correlation between subfoveal choroidal thickness and visual
acuity.ConclusionsOur findings of thinner subfoveal and temporal macular
choroidal thickness in regressed ROP support the case for choroidal involvement
in the pathogenesis of this condition.Eye advance online publication, 3 October

This review aims to assess the efficacy and safety of epithelial removal (ER) and
transepithelial (TE) corneal collagen crosslinking (CXL) for the treatment of
keratoconus. We used MEDLINE to identify all ER and TE CXL studies on keratoconic
eyes (n≥20, follow-up ≥12 months). Ex vivo and studies for non-keratoconus
indications or in conjunction with other procedures were excluded. Data on
uncorrected (UDVA) and corrected (CDVA) distance visual acuity, refractive
cylinder, maximum keratometry (Kmax), and adverse events were collected at the
latest follow-up and 1 year. Only one randomised controlled trial (RCT) qualified
inclusion. Forty-four ER and five TE studies were included. For logMAR UDVA,
CDVA, mean spherical equivalent, refractive cylinder and Kmax, at latest
follow-up 81, 85, 93, 62, and 93% ER studies vs 66.7, 80, 75, 33, and 40% TE
studies reported improvement, respectively. Whereas at 1 year, 90, 59, and 91% ER
studies vs 80, 50, and 25% TE studies reported improvement, respectively. The
majority of studies showed reduced pachymetry in both groups. Treatment failure, 
retreatment rates, and conversion to transplantation were reported to be up to
33, 8.6, and 6.25%, respectively, in ER studies only. Stromal oedema, haze,
keratitis, and scarring were only reported in ER studies, whereas endothelial
cell counts remained variable in both groups. Both ER and TE studies showed
improvement in visual acuity, refractive cylinder but Kmax worsened in most TE
studies. Adverse events were reported more with ER studies. This review calls for
more high quality ER and TE studies with comparable parameters for further
assessment of safety and efficacy.Eye advance online publication, 3 October 2014;

PurposeThe purpose of this study was to assess choroidal thickness in migraine
patients during acute migraine attacks and compare them with healthy controls,
using spectral domain optical coherence tomography (OCT).Patients and methodsIn
this prospective case-control study, choroidal thicknesses of 46 migraine
patients during acute migraine attacks and 46 age- and sex-matched healthy
subjects were measured using a high-speed, high-resolution frequency domain-OCT
device. All patients underwent a complete ophthalmic examination before the
measurements. OCT measurements were taken at the same time of day (0900 hours),
in order to minimize the effects of diurnal variation.ResultsThere was a
statistically significant difference in mean choroidal thickness between the
migraine patients during acute migraine attacks (356.3±21.46 μm) and the controls
(302.3±18.34 μm; P=0.000). There were significant differences at all measurement 
points (P<0.001 for all).ConclusionThe increased choroidal thickness of the
migraine patients during acute migraine attacks might be related to the vascular 
pathology of the disease. Further studies are needed to evaluate the
etiopathologic relationship between choroidal thickness and acute migraine
attack.Eye advance online publication, 26 September 2014;

AimTo report the visual outcome of polypoidal choroidal vasculopathy receiving
combined treatment with photodynamic therapy using Visudyne and intravitreal
ranibizumab injections, and to analyze the predictive factors of visual outcome
at 1 year post treatment.MethodsSeventy-four consecutive patients with newly
diagnosed polypoidal choroidal vasculopathy were treated with photodynamic
therapy using Visudyne and three loading doses of intravitreal ranibizumab. The
final visual outcome and polyp eradication rate at 1 year were reported. A
stepwise regression model was used to estimate the baseline clinical factors
predictive of better visual outcome and polyp eradication.ResultsVisual acuities 
at 12-months follow-up improved significantly compared with baseline from 0.828
logMAR to 0.728 logMAR (P=0.026). The mean foveal thickness decreased from
380±175 to 278±117 μm. In all 29.7% of eyes improved at least by 0.3 logMAR, and 
55.4% remained stable in visual acuity with less than 0.3 logMAR change. Overall,
85% of eyes achieved at least stable vision, 20.2% (15/74) cases achieved polyp
eradication on angiogram, and 60.8% (45/74) achieved polyp size reduction on
angiogram at 1 year. Regarding predictive factors, the baseline visual acuity
(P=0.003), no foveal involvement by abnormal choroidal vasculature (P<0.0001),
absence of hard exudates (0.001) or subretinal fluid (<0.0001) are important
clinical factors affecting the final visual outcome.ConclusionsCombination
therapy with photodynamic therapy using Visudyne and three loading doses of
intravitreal ranibizumab injections resulted in 85% success rate on visual
stabilization and 81% success rate in polypoidal lesion control.Eye advance

PurposeAnterior ischemic optic neuropathy (AION) is an important cause of acute
vision loss for which several animal models exist. It has been associated with
subretinal fluid in a previous study on patients but not yet so in animal
models.Patients and MethodsA patient presented with acute non-arteritic AION
(NAION) and underwent ophthalmic evaluation and testing including fluorescein
angiography and spectral-domain optical coherence tomography (SD-OCT). On the
basis of the patient's findings, we used SD-OCT circular and volume scans to
analyze retinal changes in a murine model of NAION.ResultsOne week after left eye
vision loss, the patient had clinical and imaging findings consistent with NAION.
On SD-OCT, there was prominent peripapillary retinal thickening consistent with
intra-retinal edema and sub-foveolar fluid. Inspired by the findings in human
AION, we looked for similar changes in murine NAION using SD-OCT. The circular
scan did not adequately detect the presence of subretinal fluid. Using the
25-line scan, which covered a larger part of the posterior pole, we found that
100% of murine AION resulted in subretinal fluid at day 1. The subretinal fluid
resolved by week 1.ConclusionThis study detailed a case of clinical NAION
associated with intra-retinal and subretinal fluid. We also found that subretinal
fluid was common in murine photochemical thrombosis model of AION and could be
found far away from the optic disc.Eye advance online publication, 26 September

PurporseTo determine the associated balance of forces of the vitreofoveal
interface in focal vitreomacular traction evolving to full-thickness macular hole
(FTMH) and to link/explain the observed changes in the context of mathematical
and physics models.Patients and methodsThis is a multicenter, prospective, and
observational case series conducted at the Vitreoretinal Department of three
different referral centers. Fellow eyes of patients with unilateral idiopathic
FTMH were included. Eighty-nine patients were included in the analysis. The
fellow normal eye of the study patients was imaged with spectral-domain optical
coherence tomography. The main outcome measure was the
optical-coherence-tomography-defined characteristics of the vitreofoveal
interface and their analysis with mathematical and physics models at the end of
follow-up period.ResultsOf the included 89 patients (66 women and 23 men; mean
age±SD, 68.5 years±9.8), 10 (11.2%) developed FTMH at the fellow eye at the end
of the follow-up period. We observed two types of vitreofoveal attachment. A
V-shaped (cord-like) configuration and a U-shaped configuration. The eyes with
the V-shaped attachment demonstrated initial structural changes in the outer
foveal layers and the eyes with the U-shaped attachment showed inner
morphological changes.ConclusionWe hypothesize that the type (V- or U-shaped) of 
the vitreofoveal attachment may affect the type and location of the initial
structural change leading to the formation of FTMH from the stage of the focal
vitreomacular traction.Eye advance online publication, 19 September 2014;

Ophthalmology Department, Training and Research Hospital, Kayseri, Turkey.

PurposeTo evaluate the correlation of subretinal fluid volume with choroidal
thickness and macular volume in acute central serous chorioretinopathy
(CSC).MethodsTwenty patients with acute unilateral treatment-naive idiopathic CSC
and 20 age-matched normal eyes were included in this prospective cross-sectional 
study. Subretinal fluid volume (SRFV) of study eyes was estimated using a
built-in segmentation-modifying tool of Spectralis spectral-domain optic
coherence tomography (SD-OCT). Subfoveal choroidal thickness (SCT) (measured with
enhanced depth imaging-OCT) and macular volume (MV) were also determined. The
correlation of SRFV with SCT and MV was analyzed statistically.ResultsThere was
no significant correlation of SRFV with SCT and MV in the study eyes (r=0.062,
P=0.796 and r= -0.061, P=0.798, respectively). The mean SCT of the study eyes,
the fellow eyes and the control eyes were 461.4±101.4, 375.3±103.7,
287.6±62.5 μm, respectively (P<0.001). The mean modified MV (determined excluding
SRF volume) of the study eyes, the macular volume of the fellow and the control
eyes was 8.57±0.59 mm(3), 8.75±0.4 mm(3) and 8.73±0.38 mm(3), respectively
(P>0.05).ConclusionsThe current study shows that subretinal fluid volume does not
correlate with subfoveal choroidal thickness. This novel finding suggests that
formation of subretinal fluid is not solely associated with choroidal vasculature
in acute CSC.Eye advance online publication, 19 September 2014;

PurposeTo compare choroidal, foveal, and peripapillary retinal thickness between 
patients with acromegaly and healthy adults.MethodsThis prospective,
cross-sectional, and comparative study included 30 patients with acromegaly
(study group) and 30 healthy subjects (control group). The subfoveal choroidal
thickness (SFCT), foveal thickness, and peripapillary retinal nerve fibre layer
thickness were measured with spectral domain optical coherence
tomography.ResultsThe mean SFCT in the study group and in the control eyes was
374.4±98.1 and 308.6±77.3 μm, respectively (P<0.001). The mean thinnest foveal
thickness value was 233.2±22.4 μm in the acromegaly group and 222.8±13.9 μm in
the control group (P=0.003). The mean peripapillary retinal nerve fibre layer
thickness did not differ significantly between the groups (P=0.34).ConclusionThe 
SFCT and foveal thickness were significantly higher in patients with acromegaly, 
whereas peripapillary retinal nerve fibre layer thickness was similar between the
groups.Eye advance online publication, 19 September 2014;

The purpose is to study the diagnostic performance of optical coherence
tomography (OCT) and alternative diagnostic tests for neovascular age-related
macular degeneration (nAMD). Methods employed are as follows:systematic review
and meta-analysis; Index test: OCT including time-domain (TD-OCT) and the most
recently developed spectral domain (SD-OCT); comparator tests: visual acuity,
clinical evaluation (slit lamp), Amsler chart, colour fundus photographs,
infra-red reflectance, red-free images/blue reflectance, fundus autofluorescence 
imaging (FAF), indocyanine green angiography (ICGA), preferential hyperacuity
perimetry (PHP), and microperimetry; reference standard: fundus fluorescein
angiography. Databases searched included MEDLINE, MEDLINE In Process, EMBASE,
Biosis, SCI, the Cochrane Library, DARE, MEDION, and HTA database. Last
literature searches: March 2013. Risk of bias assessed using QUADAS-2.
Meta-analysis models were fitted using hierarchical summary receiver operating
characteristic (HSROC) curves. Twenty-two studies (2 abstracts and 20 articles)
enrolling 2124 participants were identified, reporting TD-OCT (12 studies),
SD-OCT (1 study), ICGA (8 studies), PHP (3 studies), Amsler grid, colour fundus
photography and FAF (1 study each). Most studies were considered to have a high
risk of bias in the patient selection (55%, 11/20), and flow and timing (40%,
8/20) domains. In a meta-analysis of TD-OCT studies, sensitivity and specificity 
(95% CI) were 88% (46-98%) and 78% (64-88%), respectively. There was insufficient
information to undertake meta-analysis for other tests. TD-OCT is a sensitive
test for detecting nAMD, although specificity was only moderate. Data on SD-OCT
are sparse. Diagnosis of nAMD should not rely solely on OCT.Eye advance online

PurposeTo compare multimodal imaging in detecting lacquer cracks in highly myopic
eyes, and to correlate these findings with those of spectral-domain optical
coherence tomography (SD-OCT).MethodsAn observational case series study. Patients
with a refractive error worse than -8 diopters and lacquer cracks were recruited.
The rates of detection of the lacquer cracks using multimodal imaging including
near-infrared reflectance (NIR) imaging, fundus autofluorescence (FAF) imaging,
and fluorescence angiography (FA) were compared. The characteristic findings of
multimodal imaging were correlated with those of SD-OCT.ResultsNIR imaging was
more sensitive (92.9%) in detecting lacquer cracks than either FAF (12.5%) or FA 
(67.9%). Lacquer cracks showed hyperreflectance on NIR, and they were
consistently associated with a continuous retinal pigment epithelium-Bruch's
membrane complex, thinner choroid, and acoustic shadows on SD-OCT.ConclusionsNIR 
imaging is superior to blue laser light (FAF and FA) imaging in detecting lacquer
cracks. SD-OCT in combination with NIR located primary pathological lacquer
cracks in the intact retinal pigment epithelium-Bruch's membrane complex as well 
as thinner choroid. These findings indicate that multimodal cSLO and SD-OCT
imaging allow for detecting of lacquer cracks in highly myopic eyes.Eye advance

PurposeAmong some local side effects of prostaglandin-associated periorbitopathy 
(PAP), deepening of the upper eyelid sulcus (DUES) is the most prominent clinical
feature, and is one of the most significant adverse cosmetic events. Here, we
prospectively investigated the incidence of DUES in Japanese open-angle glaucoma 
patients initially treated with latanoprost (Xalatan 0.005%) ophthalmic
solution.MethodsThis was an open-label prospective study. Facial photographs and 
subjective reports of the recognition of DUES were obtained at the beginning of
latanoprost treatment and at 2, 4, and 6 months thereafter. Intraocular pressure 
(IOP) was measured at three consecutive visits before and after treatment with
latanoprost. The incidence of DUES was evaluated objectively by three blinded
investigators who compared the series of photographs.ResultsA total of 52 eyes of
52 newly diagnosed open-angle glaucoma Japanese patients (28 males, 24 females)
were evaluated. The objective rate of DUES was 1/52 (2%; 95% CI 0.05 to 10.7%) at
2 months, 2/52 (4%; 95% CI 0.5 to 13.9%) at 4 months, and 3/52 (6%; 95% CI 1.2 to
16.9%) at 6 months. During this period, no patient self-reported an occurrence of
DUES. Mean IOPs before and after treatment were 16.5±2.9 and 13.8±3.0 mm Hg,
respectively. Latanoprost reduced the IOP significantly (P<0.0001, paired
t-test).ConclusionsLatanoprost caused DUES rarely and had a robust IOP-lowering
effect in Japanese glaucoma patients.Eye advance online publication, 19 September

BackgroundTo investigate the changes in inner foveal contour after surgery for
macular hole (MH) and its clinical implications.MethodsThis retrospective
observational case series included 66 eyes from 66 patients who underwent surgery
for MH. Notching of tissue was defined as an abrupt alteration in the inner
contour of the parafoveal tissue based on postoperative optical coherence
tomography (OCT) image. The distance between the parafoveal edges of the outer
plexiform layer (OPL) was defined as the inter-OPL distance. The inter-OPL
distance was divided into nasal, temporal, superior, and inferior lengths. The
difference in the lengths of each direction between the early and late
postoperative period was compared between directions with and without
notching.ResultsThe early and late postoperative examination was performed at
4.6±2.9 weeks and 6.2±0.6 months, respectively. Notching of tissue was noted in
54 eyes (81.8%). In 53 eyes with a measurable inter-OPL distance, the notching of
tissue was noted in 45 eyes (84.9%) regardless of preoperative MH size. The mean 
amount of foveal tissue elongation that occurred during the designated period was
104.6±68.8 and 78.4±72.9 μm in the directions with and without the notching of
tissue (P<0.001), respectively.ConclusionsThe changes in the inner foveal
contour, including notching of tissue and elongation of foveal tissue, were noted
in the majority of eyes after MH surgery. Notching of tissue on OCT image could
be a clinical marker for the development of foveal tissue elongation after MH
surgery.Eye advance online publication, 19 September 2014;

It is becoming increasingly evident that epigenetic mechanisms influence gene
expression and can explain how interactions between genetics and the environment 
result in particular phenotypes during development. The extent to which this
epigenetic effect contributes to phenotype heritability in age-related macular
degeneration (AMD) is currently ill defined. However, emerging evidence suggests 
that epigenetic changes are relevant to AMD and as such provide an exciting new
avenue of research for AMD. This review addresses information on the impact of
posttranslational modification of the genome on the pathogenesis of AMD, such as 
DNA methylation changes affecting antioxidant gene expression, hypoxia-regulated 
alterations in chromatin structure, and histone acetylation status in relation to
angiogenesis and inflammation. It also contains information on the role of
non-coding RNA-mediated gene regulation in AMD at a posttranscriptional (before
translation) level. Our aim was to review the epigenetic mechanisms that cause
heritable changes in gene activity without changing the DNA sequence. We also
describe some long-term alterations in the transcriptional potential of a cell,
which are not necessarily heritable but remains to be defined in the future.
Increasing understanding of the significance of common and rare genetic variants 
and their relationship to epigenetics and environmental influences may help in
establishing methods to assess the risk of AMD. This in turn may allow new
therapeutic interventions for the leading cause of central vision impairment in
patients over the age of 50 years in developed countries.Search strategyWe
searched the MEDLINE/PubMed database following MeSH suggestions for articles
including the terms: 'ocular epigenetic mechanisms', 'human disease epigenetics',
and 'age-related macular degeneration genetics'. The headline used to locate
related articles in PubMed was 'epigenetics in ocular disease', and to restrict
search, we used the headlines 'DNA methylation in age related macular
degeneration', 'altered gene expression in AMD pathogenesis'. A manual search was
also based on references from these articles as well as review articles.Eye
