PURPOSE: To analyze the outer retinal and retinal pigment epithelium (RPE) features of reticular pattern dystrophy of the retina using spectral-domain optical coherence tomography (SDOCT). DESIGN: Retrospective observational case series. METHODS: Consecutive patients with reticular pattern dystrophy of the retina underwent a complete ophthalmologic examination, including assessment of best-corrected visual acuity (BCVA), fundus biomicroscopy, fluorescein angiography (FA), and SDOCT. RESULTS: Twenty-two eyes of 13 patients (6 men, 7 women, mean age 68.6 +/- 14.5 years) were included. In the foveal area, the RPE layer appeared normal in 45.5% of eyes, while small RPE elevations and RPE bumps were detected in 31.8% and 22.7% of eyes, respectively. The SDOCT scans showed disruption of inner segment/outer segment (IS/OS) junction in 54.6% of eyes, a slight elevation in 59.1% of eyes, and an absence in 45.5% of eyes. The outer limiting membrane (OLM) appeared disrupted in 50.0% of eyes: absent in 22.7% of eyes, and elevated in 63.6% of eyes. Hyper-reflective subretinal material accumulation or hyporeflective subretinal lesions in the retrofoveolar region were detected in 70% and in 20% of eyes, respectively. SDOCT showed hyporeflective retinal pseudocysts in 13.6% of eyes. CONCLUSION: In this study on reticular pattern dystrophy of the retina, SDOCT provided a description of the material deposits and the alterations of the RPE and the different retinal layers. We observe that the lesions present specific features distinct from other macular dystrophies, but closer to those reported in fundus flavimaculatus than those reported in adult-onset foveomacular vitelliform dystrophy. Further analyses are needed, particularly to analyze the progression of the lesions. ((C) 2013 by Elsevier Inc. All rights reserved.)

PURPOSE To describe the case of a patient presenting with persistent placoid maculopathy imaged with optical coherence tomography angiography. METHODS Case report of a 72-year-old man who presented with blurred vision in his right eye. fundus photography, fluorescein angiography, infracyanine green angiography, fundus autofluorescence imaging, spectral domain optical coherence tomography, optical coherence tomography angiography, and split spectrum amplitude decorrelation angiography were performed. The diagnosis was made based on ophthalmological manifestations and multimodal imaging. RESULTS The spectral domain optical coherence tomography image of the right eye revealed disruption of the ellipsoid layers, and an underlying sliver of hyporeflectance. In the left eye, there were no obvious changes on spectral domain optical coherence tomography. In both eyes, infracyanine green angiography showed hypocyanescence of the lesions, persisting throughout late phases. In optical coherence tomography angiography, imaging of the choroidal capillary layers revealed hyposignal lesions, topographically corresponding exactly to hypocyanescent lesions on infracyanine green angiography. CONCLUSION In this patient, a distinct hyposignal on optical coherence tomography angiography, combined with hypocyanescence on infracyanine green angiography, was interpreted as indicating focal hypoperfusion of the choriocapillaris.

Age related macular degeneration (AMD) is the leading cause of vision loss in the elderly in developed countries. Genetic factors play a major role in this multifactorial and polygenic disease. Genomewide analysis identified two loci on 1q25-31 and 10q26 chromosomes associated with AMD, and association studies highlighted the implication of SNPs located in the complement H factor gene (CFH) on 1q25-31 and in PLEKHA1-HTRA1-LOC387715 on 10q26 in the disease. Homozygous carriers for the at-risk alleles of the CFH, HTRA1, and LOC387715 genes have an increased risk to develop exudative AMD with odds ratio of 6.2, 6.9, et 7.3 respectively. Moreover, other genes involved in the complement cascade, namely the genes of the C2, C3 component, and factor B, are associated to the disease. The SCARB1 gene has also recently been associated to AMD. Genotype-phenotype correlations have been performed in AMD patients and found that occult CNV are more often associated to CFH at-risk allele and classic CNV to HTRA1 at-risk allele. This last allele seems also linked to more severe forms of the disease. These new major genetic factors could lead to a new clinical approach of AMD and to the discovery of new therapeutic targets.

Choroidal neovascularization (CNV) secondary to traumatic rupture of Bruch's membrane is a rare condition, without standardized treatment. Here we describe one case of CNV related to traumatic rupture of Bruch's membrane which was successfully treated with intravitreal injection of ranibizumab.A 14-year-old patient was referred for ocular contusion, complicating interpapillomacular rupture of Bruch's membrane in left eye. Indeed, a correct initial visual acuity, juxtafoveolar CNV appeared 4 months later on the border of Bruch's membrane rupture. The patient was treated with an off-label intravitreal ranibizumab because of worsening of visual acuity.One month after intravitreal injection, visual acuity improved, from 20/40 to 20/25. At 12-month follow-up, visual acuity remained at 20/25, fundus examination. Fluorescein angiography, indocyanine green angiography and optic coherence tomography showed fibrotic evolution of CNV. The Bruch's membrane rupture remained stable. No side-effect of intravitreal injection of ranibizumab was observed.For this patient affected with CNV secondary to traumatic Bruch's membrane, one single intravitreal ranibizumab injection was efficient, with 1-year follow-up.

Purpose:To analyze retrospectively the efficacy of intravitreal ranibizumab injections for the management of choroidal neovascularization in patients with angioid streaks over a long term.Methods:In this nonrandomized, double-center, retrospective, interventional case series, a consecutive series of patients affected with choroidal neovascularization associated with angioid streaks were treated with intravitreal ranibizumab injections (0.5 mg/0.05 mL). Best-corrected visual acuity, fundus photography, optical coherence tomography, and fluorescein angiography were examined before and after treatment. The primary endpoint was the percentage of eyes with stable or improved visual acuity at the end of follow-up (loss of less than 3 Early Treatment Diabetic Retinopathy Study lines). Secondary endpoints were the percentage of eyes with stable or decreased macular thickness on optical coherence tomography (less than a 10% increase in macular thickness) and the percentage of eyes with persistent leakage on fluorescein angiography at the last observation carried forward.Results:Thirty-five eyes of 27 patients were treated with repeated intravitreal ranibizumab injections (mean of 9.9 7.2 injections, range 2-26) for a mean of 48.6 +/- 17.1 months (range 8-66). At the end of follow-up, best-corrected visual acuity was stabilized or improved in 22 of 35 eyes (62.9%). Macular thickness had stabilized or decreased in 16 of 35 eyes (45.7%). At the last follow-up examination, on fluorescein angiography, no further leakage was observed in 27 of 35 eyes (77.1%).Conclusion:In this large series of patients with choroidal neovascularization associated with angioid streaks followed for 4 years, ranibizumab injections allowed stabilization of best-corrected visual acuity in most eyes. Ranibizumab appear as an effective therapeutic option in CNV associated with angioid streaks over long time.

Purpose Genetic susceptibility could be modified by environmental factors and may also influence differential responses to treatments for age-related macular degeneration (AMD). We investigated whether genotype could influence response to docosahexaenoic acid (DHA)-supplementation in the occurrence of choroidal new vessels (CNV). Methods The Nutritional AMD Treatment 2 (NAT2) study was a randomized, placebo-controlled, double-blind, parallel, comparative study, including 250 patients aged 55 to 85 years with early lesions of age-related maculopathy, visual acuity better than 0.4 Logarithm of Minimum Angle of Resolution units in the study eye and neovascular AMD in the fellow eye. Patients were randomized at baseline to receive either 3 daily fish-oil capsules, each containing 280 mg DHA, 90 mg EPA and 2 mg Vitamin E, or placebo. Results Patients carrying the risk allele (C) for CFH Y402H had no statistically significant increased risk for developing CNV in the study eye (Hazard Ratio (HR)=0.97; 95% Confidence Interval (CI): 0.54-1.76 for heterozygous and HR=1.29; 95%CI: 0.69-2.40 for homozygous). Patients carrying the risk allele (T) for ARMS2 A69S had no statistically significant increased risk for developing CNV in the study eye (HR=1.68; 95%CI: 0.91-3.12) for heterozygous and HR=1.78; 95%CI: 0.90-3.52 for homozygous). A significant interaction was observed between CFH Y402H and DHA-supplementation (p=0.01). We showed a protective effect of DHA-supplementation among homozygous non-risk patients. Among these patients, occurrence of CNV was 38.2% in placebo group versus 16.7% in DHA group (p=0.008). Conclusions These results suggest that a genetic predisposition to AMD conferred by the CFH Y402H variant limits the benefit provided by DHA supplementation.

PURPOSE We assessed the associations of serum, red blood cell membranes (RBCM) and dietary long-chain n-3 polyunsaturated fatty acids (LC-PUFAs) with neovascular age-related macular degeneration (AMD). METHODS We included 290 patients of the Nutritional AMD Treatment 2 Study (NAT2) with neovascular AMD in one eye and early AMD lesions in the other eye, and 144 normal vision controls without AMD. Dietary intake of seafood was estimated by food frequency questionnaire. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) composition in serum and RBCM were determined by gas chromatography from 12-hour fasting blood samples and was expressed as percentages of total fatty acids profile. Logistic regressions estimated associations of neovascular AMD with dietary intake of seafood and circulating n-3 LC-PUFAs. RESULTS Dietary oily fish and seafood intake were significantly lower in AMD patients than in controls. After adjustment for all potential confounders (age, sex, CFH Y402H, ARMS2 A69S, and ApoE4 polymorphisms, plasma triglycerides, hypertension, hypercholesterolemia, and family history of AMD), serum EPA was associated significantly with a lower risk for neovascular AMD (odds ratio [OR] = 0.41; 95% confidence interval [CI], 0.22-0.77; P = 0.005). Analysis of RBCM revealed that EPA and EPA+DHA were associated significantly with a lower risk for neovascular AMD (OR = 0.25; 95% CI, 0.13-0.47; P < 0.0001 and OR = 0.52; 95% CI, 0.29-0.94; P = 0.03, respectively). CONCLUSIONS The RBCM EPA and EPA+DHA, as long-term biomarkers of n-3 dietary PUFA status, were associated strongly with neovascular AMD and may represent an objective marker identifying subjects at high risk for neovascular AMD, who may most benefit from nutritional interventions.

PURPOSE: To investigate the effects of ranibizumab 0.5 mg on gray hyper-reflective subretinal lesions diagnosed by spectral-domain optical coherence tomography (SD OCT) in patients with exudative age-related macular degeneration (AMD). DESIGN: Retrospective interventional study. METHODS: Data from 28 consecutive patients affected with neovascular AMD that presented subretinal hyper-reflective lesions as visualized by SD OCT were collected. Gray hyper-reflective subretinal lesion characteristics were analyzed before and after intravitreal ranibizumab 0.5 mg injection. RESULTS: Thirty eyes of 28 patients (5 male, 23 female, aged 57-91 years) were included. At study entry, gray lesion was associated with exudative features in 24 of 30 eyes (80%), including subretinal fluid (SRF) in 20 of 30 eyes (67%) and retinal cystoid spaces in 11 of 30 eyes (37%). Twenty-four eyes with exudative features at study entry received prompt treatment; 6 eyes without exudative features at study entry received deferred treatment (after 1 month observation), when exudative signs emerged (SRF in 3/6 eyes and retinal cystoid spaces in 5/6 eyes). Ninety-three percent of the gray lesions responded to ranibizumab treatment at 2 months and 77% at 6 months. Gray hyper-reflective subretinal lesion thickness was significantly reduced after treatment at both 2 months (from 482 +/- 116 mu m to 367 +/- 102 mu m, P < .0001) and 6 months (from 482 +/- 116 mu m to 369 +/- 71 mu m, P < .0001). CONCLUSION: Our findings suggest that gray hyper-reflective subretinal lesions might be considered as a qualitative criterion for retreatment of exudative AM:D. They may represent an early sign of active choroidal neovascularization, and should prompt to early treatment. ((C) 2014 by Elsevier Inc. All rights reserved.)

PURPOSE. To compare macular choroidal thickness (MCT) in eyes with adult onset foveomacular vitelliform dystrophy (AOFVD) and eyes with AMD. METHODS. Five groups of 38 eyes each were included in a prospective, observational, comparative study: AOFVD eyes with fluid accumulation; AOFVD fellow eyes without fluid (early stage); advanced exudative (wet) AMD; advanced dry AMD; and healthy normal eyes. All study eyes underwent a comprehensive ophthalmologic examination. Macular choroidal thickness was measured using enhanced depth imaging optical coherence tomography (EDI-OCT). RESULTS. Subfoveal choroidal thickness (SFCT) in AOFVD with subretinal fluid (325.66 +/- 85.98 mu m) was significantly (P < 0.001) thicker compared with that in exudative AMD (158.55 +/- 57.87 mu m) and in dry AMD (157.53 +/- 67.08 mu m). Also, in AOFVD, the choroid was significantly (P = 0.001) thicker than that in the normal group (255.87 +/- 87.46 mu m). However, in AOFVD, there was no significant difference (P = 0.69) between the SFCT in the study eye and in the fellow eye (317.66 +/- 90.04 mu m). The choroidal thickness at each of the other 12 measured points showed similar results. CONCLUSIONS. This study demonstrates choroidal thickening in AOFVD in contrast with the choroidal thinning observed in advanced AMD. These findings suggest that the pathogenic mechanisms in AOFVD are different from those in exudative AMD. Choroidal thickness measurement could help differentiate the challenging diagnosis between exudative AMD and the advanced stage of AOFVD (with fluid accumulation but without choroidal neovascularization).

Purpose: To assess intraobserver and interobserver agreement among physicians with different degrees of clinical experience, using a novel fundus autofluorescence semiautomated software for quantification of geographic atrophy in clinical setting. Methods: Fundus autofluorescence frames (excitation: 488 nm; emission: 500-700 nm) of 29 eyes (20 patients; mean age, 79.6 +/- 6.2 years) with geographic atrophy secondary to age-related macular degeneration, and no signs of choroidal neovascularization, were analyzed using Region Finder, a semiautomated software embedded in Spectralis (Heidelberg Engineering, Heidelberg, Germany). For each study eye, semiautomated atrophy identification and quantification were independently performed, twice (in a 2-week time frame), by 3 readers with different degrees of clinical experience (2 fellows, and 1 resident). Intraobserver and interobserver agreements were assessed. Results: Mean difference in intraobserver agreement (Bland-Altman statistics) ranged from -0.17 mm(2) to 0.13 mm(2). Intraobserver agreement was excellent until the geographic atrophy threshold value of 15.72 mm(2). Variability correlated with the size of atrophy. Mean difference in interobserver agreement (Bland-Altman statistics) ranged from -0.25 mm(2) to 0.27 mm(2), with no significant difference between senior and junior readers. Multifocal lesion or foveal involvement in atrophy was not the cause of disagreement. Conclusion: Region Finder is a reliable tool for the identification and quantification of geographic atrophy in patients with age-related macular degeneration, in a clinical setting even when performed by junior reader.

To compare choroidal thickness (CT) between eyes with adult onset foveo macular vitelliform dystrophy (AOFVD) eyes with age-related macular degeneration (AMD). 5 group (38 eyes each) with AOFVD, fellow eyes with AOFVD wet AMD, dry AMD, age-matched normal subjects.Choroidal thickness was measured using enhanced-depth imaging optical coherence tomography (EDI-OCT) with Spectralis. Subfoveal choroidal thickness (SFCT) in each eye was analyzed with measurement of the vertical distance from the Bruch’s membrane to the innermost choroid/sclera junction, at 500µm intervals up to 1500µm, from temporal to nasal and from superior to inferior to the center of the fovea.The difference between SFCT AOFVD (325.66 +/- 86 µm) versus CT in wet AMD (168.21 +/- 57.7 µm) and CT in dry AMD (158.77 +/- 68 µm) and versus elderly normal (238,33 +/- 83µm) are statistically significant, (p <

Background Our purpose was to describe the different morphological features in adult onset foveomacular vitelliform dystrophy (AOFVD), using en face enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT). Methods Thirty eyes of 22 consecutive patients presenting with diagnosis of AOFVD were enrolled. Diagnosis of AOFVD was concluded based on fundus examination, autofluorescence imaging, fluorescein angiography and SD-OCT. En face OCT imaging was obtained with the Spectralis EDI SD-OCT; 97 inverted sections (nine averaged B-scans per image) were acquired. Results On en face OCT, vitelliform lesions appeared as regular concentric rings of different reflectivity. From the periphery to center of the ring, we observed: (1) the hypereflective ring representing the inner segment/outer segment (IS/OS) junction, which was continuous in 23 out of 30 eyes, and (2) a well-detectable hyporeflective ring between the IS/OS junction and vitelliform material in 20 out of 30 eyes; the innermost composant of the lesion was hypereflective, and it corresponded to vitelliform material. In eight out of 30 eyes, a hyporeflective "croissant"-shaped lesion with inferior concavity in the upper part of the hyperreflective material was present. Hypereflective retinal pigment epithelium (RPE) elevations or bumps were detected in 25 out of 30 eyes. These areas of focal RPE thickening or bumps appeared to be intensely hypereflective on infrared reflectance imaging. Conclusion En face imaging of the retina helps visualizing the distribution of vitelliform material in AOFVD. The sedimentation of vitelliform lesions is characterized by a upper "croissant"-shaped hypoflectivity. The bumps/thickening of RPE appeared as hypereflective lesions on IR imaging.

Purpose: To analyze the genetic and environmental factors associated with reticular pseudodrusen (RPD) in age-related macular degeneration (AMD). Methods: In a large population, AMD patients (n = 519) with and without RPD were assessed with a standardized examination including infrared images and spectral domain optical coherence tomography scans. Three groups were defined: Group 1: AMD patients with RPD (n = 105); Group 2: AMD patients without RPD (n = 414); and Group 3: controls with no AMD and no RPD (n = 430). Four genes associated with AMD (CFH, ARMS2/HTRA1, C3, apolipoprotein E) and environmental factors were assessed between the 3 groups. Results: None of the environmental factors studied were more significantly associated to either Group 1 or Group 2. The odds ratios and 95% confidence intervals for individuals homozygous for the CFH risk allele were 4.0 (2.1-7.7) ([95% confidence interval: 2.1-7.7]; P < 0.0004) in Group 1 and 4.3 ([2.6-7.1]; P < 0.0004) in Group 2, compared with Group 3. The odds ratios for individuals homozygous for the ARMS2 risk allele for Groups 1 and 2 compared with Group 3 were 16.3 ([7.6-35.4]; P < 0.0004) and 11.9 ([6.3-22.3]; P < 0.0004), respectively. None of the genotypes studied were more significantly associated to Group 1 than Group 2. Conclusion: Genotypes known to be associated with AMD were similarly observed in patients with and without RPD. RETINA 33: 998-1004, 2013

Age-related macular degeneration (AMD) is a complex, multifactorial disease associated with environmental and genetic factors. This review emphasizes the clinical impact of the major genetic factors mainly located in the complement factor H gene and on the 10q26 locus, and their current and future implications for the management of AMD.

Purpose: To evaluate the efficacy and the safety of intravitreal ranibizumab injection (Lucentis) in eyes with macular oedema secondary to central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO). Methods: The files of consecutive patients (34 eyes, 15 CRVO, 19 BRVO) were retrospectively analysed. Intravitreal injections of 0.5 mg ranibizumab were administered; retreatment was based on acuity visual changes and optical coherence tomography findings. Patients received 2–4 injections (mean, 2.1). Mean follow-up was 7 months. Results: After the first injection, mean best-corrected visual acuity (BCVA) improved from 20/160 to 20/80 and mean central retinal thickness (CRT) decreased significantly from 549 to 301 μm (p

Purpose To describe the different morphological features in adult onset foveomacular vittelliform dystrophy (AOFVD) using high-resolution spectral domain optical coherence tomography (OCT). Design Prospective observational case series. Methods Complete ophthalmologic examination, including spectral domain OCT, was performed in 49 consecutive AOFVD patients (60 eyes). Results In 28/60 eyes, spectral domain OCT showed hyper-reflective clumps within the outer plexiform and outer nuclear layers. In 9/60 eyes, the photoreceptor inner segment/outer segment (IS/OS) interface appeared highly reflective like a shell all around the vitelliform material, and appeared irregular and discontinued in 27/60 eyes. The Verhoeff membrane was clearly visible at the border of the lesion, disappeared over the vitelliform lesion in 20/60 eyes, became thickened and less defined on the outer aspect of the lesion in 11/60 eyes, appeared without noticeable alterations in 10/60 eyes and not well defined in 19/60 eyes. The vitelliform material appeared as a highly reflective dome-shaped lesion (homogeneous in 14/60 eyes and heterogeneous in 36/60 eyes) located between the photoreceptor layer and the retinal pigment epithelium (RPE). In 10/60 eyes, the macular lesion appeared as hypo/a-reflective. The RPE appeared irregular in 14/60 eyes, with hyper-reflective mottling on its inner aspect. We observed discrete RPE detachments in 29/60 eyes. Conclusions We hypothesise that early changes involve the layer between RPE and the IS/OS interface, first with vitelliform material accumulation beneath the sensory retina, and then with IS/OS alterations, pigments migration towards inner layers and fluid accumulation. These changes come with RPE alterations such as hypertrophy or sub-RPE deposits.

PURPOSE: To assess morphologic changes associated with retinal flecks in fundus flavimaculatus using spectral-domain optical coherence tomography (SD-OCT). DESIGN: Observational case series. METHODS: Simultaneous recordings of SD-OCT and confocal scanning laser ophthalmoscope (cSLO) fundus autofluorescence images were obtained in fundus flavimaculatus patients. Morphologic aspects of the retinal flecks were analyzed and classified. RESULTS: Thirty-one eyes of 17 consecutive patients (8 male, 9 female; mean age 47.9 +/- 17.1 years) were included for analysis. SD-OCT revealed 5 distinct types of lesions. Group A lesions were limited to the outer segment (OS) of the photoreceptors, the retinal pigment epithelium (RPE) interdigitations, and the RPE/Bruch membrane complex. Group B showed a protrusion of the hyper-reflective material through the interface of inner segment (IS)/OS of the photoreceptors up to the external limiting membrane. A further protrusion of the hyper-reflective material into the outer nuclear layer was seen in group C lesions. Group D lesions were characterized by an accumulation of the hyper-reflective material limited to the outer nuclear layer. Type E lesions can be described as drusen-like retinal pigment detachments. No significant correlation between the different types of flecks and visual acuity was observed (P > .05). CONCLUSIONS: SD-OCT allows one to distinguish at least 5 different types of lesions associated with retinal flecks in fundus flavimaculatus. The ability to characterize the different types of flecks and to analyze the photoreceptor layers surrounding these lesions suggests that SD-OCT might have a potential clinical role in the evaluation and follow-up of the structural changes in fundus flavimaculatus.

PURPOSE Major genetic risk factors have recently been identified for age-related macular degeneration (AMD), including the ARMS2/LOC387715 and CFH at-risk polymorphisms. The study was conducted to establish correlations between the AMD genotype and both the phenotype and severity of AMD. METHODS In a prospective cohort of 1216 AMD patients, four genotypic homozygous groups were identified (n = 264): double homozygous for wild-type alleles (group 1, n = 49), homozygous for the at-risk allele of ARMS2/LOC387715 only (group 2, n = 57), homozygous for the at-risk allele of CFH only (group 3, n = 106), and double homozygous for both at-risk alleles (group 4, n = 52). The phenotypic classification of exudative AMD was based on fluorescein angiography. RESULTS Mean age at presentation was significantly lower in group 4 than in group 1 (P < 0.014). Patients in group 4 presented more often with bilateral CNV and fibrovascular scars than did patients in group 1 (P < 0.001 and < 0.0031 respectively) and with significantly lower visual acuity (VA) in the first affected eye than did patients in group 1 (P < 0.02). Patients in group 2 presented with worse VA than did patients in group 3 (P < 0.003). Classic CNV was more commonly associated with the at-risk allele of the ARMS2/LOC387715 locus than with the at-risk allele of the CFH gene (P < 0.026). CONCLUSIONS This study demonstrates an association between the at-risk allele of the ARMS2/LOC387715 locus and classic CNV, fibrovascular lesions, and poor VA. Individuals double homozygous for both at-risk alleles had a higher risk of being affected with a severe form of AMD at an earlier age.

Purpose: The purpose of this study was to evaluate the efficacy of intravitreal injections of ranibizumab in choroidal neovascularization secondary to pathologic myopia. Methods: A prospective case series of 32 eyes of 32 patients affected with choroidal neovascularization secondary to pathologic myopia treated by intravitreal injections of ranibizumab. Best-corrected visual acuity, fundus examination, fluorescein angiography, indocyanine green angiography, and spectral domain-optical coherence tomography were performed for the diagnosis of myopic choroidal neovascularization. Best-corrected visual acuity and central retinal thickness measurement were performed monthly during the follow-up. Results: The median number of injections was 3 with a median follow-up of 17 months. The median visual acuity at baseline was 20/100 and improved to 20/50 at final examination (P < 0.0001). Best-corrected visual acuity improved by >= 3 lines in 15 of 32 eyes (46.8%). The median central thickness was 336 mu m (range, 179-663 mu m) at baseline and 233 mu m (range, 125-465 mu m) at final examination (P < 0.0001). No severe drug-related side effect was reported. Conclusion: In our series of myopic choroidal neovascularization, intravitreal injections of ranibizumab showed visual acuity improvement and retinal thickness reduction. Further prospective multicentric clinical trials are needed to evaluate the safety and the efficacy of this treatment. RETINA 30: 399-406, 2010

Purpose To study the effect of anti–vascular endothelial growth factor (VEGF) therapy on subretinal hyperreflective exudation detected by spectral-domain optical coherence tomography (SD OCT) in myopic choroidal neovascularization (CNV). Design Retrospective consecutive observational cohort study. Methods Thirty-one eyes of 31 consecutive highly myopic patients with CNV and showing a subretinal hyperreflective exudation on SD OCT were included. Morphologic changes were assessed before and after anti-VEGF therapy, based on the subretinal hyperreflective exudation thickness, retinal thickness at the level of the CNV, and central macular thickness. Results After anti-VEGF treatment (mean follow-up of 1.9 ± 0.8 months, mean number of injections 1.8 ± 0.6), the subretinal hyperreflective exudation regressed completely in 29 of 31 eyes (93.5%) and partially in 2 of 31 eyes (6.5%). Mean subretinal hyperreflective exudation thickness, mean retinal thickness at the level of the CNV, and mean central macular thickness significantly decreased from 102 ± 50 μm to 2.6 ± 10.2 μm ( P P P = .0008), respectively. Conclusion The subretinal hyperreflective exudation was an SD OCT finding that correlated with signs of active myopic CNV (either subretinal fluid/intraretinal cysts on SD OCT or dye leakage on fluorescein angiography) and responded to treatment with anti-VEGF agents. The presence of a subretinal hyperreflective exudation on SD OCT could help in making decisions on the need to perform or not perform fluorescein angiography, and regarding treatment or retreatment.

SD-OCT was performed immediately, followed by fluorescein and infracyanine angiography at eight days and then at three weeks.Results: At presentation, a bubble of sub-macular deposit was observed on the right macula with central golden micronodules in a honeycomb pattern. SD-OCT showed an “anterior dislocation” of all the retinal layers up to the inner/outer segment (IS/OS) line and irregular deposits at the OS level together with thickening of the retinal pigment epithelial (RPE) layer. As visual acuity increased, eight days later, the OCT showed reduction of the sub-retinal deposits and an abnormal hyperflectivity of the sub-retinal and RPE layers was observed. The patient showed a positive serology for picornavirus.Discussion: The acute SD-OCT sections of this patient with ARPE were compared with histological sections of a 35 day old Royal College of Surgeons rat. Similar findings could be observed, with preservation of the IS/OS line and accumulation of debris at the OS level, suggesting that ARPE symptoms could result from a transient phagocytic dysfunction of the RPE at the fovea, inducing reversible accumulation of undigested OS. Picornaviruses comprising enterovirus and coxsachievirus described as being associated with acute chorioretinitis. In this case, it was responsible for ARPE.Conclusion: We hypothesize that ARPE syndrome results from a transient dysfunction of RPE, which can occur as a post viral reaction.Keywords: acute retinal pigment epithelitis, picornavirus, SD-OCT

Purpose: To evaluate the efficacy of intravitreal injections of ranibizumab for choroidal neovascularization associated with adult-onset foveomacular vitelliform dystrophy. Methods: Retrospective case series of 24 eyes affected with choroidal neovascularization associated with adult-onset foveomacular vitelliform dystrophy treated by intravitreal injections of ranibizumab (0.5 mg/0.05 mL). Best-corrected visual acuity, fundus examination, spectral domain optical coherence tomography, fundus autofluorescence, and fluorescein and indocyanine green angiography were performed for the diagnosis of adult-onset foveomacular vitelliform dystrophy and choroidal neovascularization. After initial 3 monthly injections of ranibizumab, patients were followed up monthly and retreated if neovascular activity persisted. Outcome measure was the proportion of patients losing fewer than 3 lines of visual acuity from baseline to 12 months (final visit). Results: At final visit, the mean number of ranibizumab injections was 4.5 +/- 1.29. From baseline to final visit, 21 of 24 eyes (87.5%) lost fewer than 3 lines of visual acuity. Mean best-corrected visual acuity did not change significantly from baseline to final visit (0.37 +/- 0.2 logarithm of the minimum angle of resolution vs. 0.30 +/- 0.25 logarithm of the minimum angle of resolution, respectively; P = 0.115). Mean central macular thickness significantly decreased from baseline to final visit (327 +/- 83 mu m vs. 260 +/- 57 mu m, respectively; P = 0.001). Conclusion: In this series, ranibizumab succeeded in stabilizing best-corrected visual acuity in patients with choroidal neovascularization associated with adult-onset foveomacular vitelliform dystrophy. Ranibizumab seems to be a reasonable therapeutic option in this condition. RETINA 33:513-521, 2013
