Abstract
This cross-sectional study compared optical coherence tomography angiography (OCTA) parameters between older Black and White adults with systemic comorbidities in an effort to further understand racial differences in the retinal microvasculature. We analyzed vessel density at the superficial (SCP), intermediate (ICP), and deep capillary plexuses (DCP), foveal avascular zone (FAZ) parameters, and blood flow area (BFA) at the choriocapillaris. We used a mixed-effects linear regression model, controlling for hypertension and two eyes from the same subject, to compare OCTA parameters. Black subjects had lower foveal vessel density at the SCP and ICP, while no differences were observed at the parafovea or 3x3 mm macular area of any capillary layer. Black subjects had greater FAZ area, perimeter, and FD-300, a measurement of vessel density in a 300 μm wide ring around the FAZ. Black subjects also had lower BFA at the choriocapillaris. Within a cohort of subjects without hypertension, these differences remained statistically significant, with the exception of foveal vessel density at the SCP and foveal BFA of the choriocapillaris. These findings suggest that normative databases of OCTA parameters must strive to be diverse in nature to adequately capture differences across patient populations. Further study is required to understand if baseline differences in OCTA parameters contribute to epidemiological disparities in ocular diseases.

Abstract
This study compared macular capillary parameters between healthy black and white subjects using optical coherence tomography angiography (OCTA). We measured vessel density (VD) of superficial (SCP), intermediate (ICP), and deep (DCP) capillary plexuses and choriocapillaris blood flow area (BFA) of the fovea, parafovea and total 3 mm-diameter circular area centered on the fovea, as well as the foveal avascular zone (FAZ) parameters, controlling for axial length. Black subjects had lower foveal and parafoveal VD in the SCP (p = 0.043 and p = 0.014) and the ICP (p = 0.014 and p = 0.002). In the DCP, black subjects had a trend toward lower foveal and parafoveal VD. Black subjects had decreased choriocapillaris BFA in the total 3 mm area (p = 0.011) and the parafovea (p = 0.033), larger FAZ area (p = 0.006) and perimeter (p = 0.014), and a higher capillary density in a 300 μm wide region around the FAZ (FD-300) (p = 0.001). There was no significant difference in FAZ acircularity index. To our knowledge, this is the first report analyzing the three distinct retinal capillary plexuses and identifying differing baseline VD, choriocapillaris and FAZ parameters in healthy young black compared to white subjects. Larger studies are needed to validate these findings and better understand racial differences in vulnerability to ocular diseases.

Abstract
Purpose: We report a case of recurrent macular hole (MH) formation and spontaneous closure in the absence of any vitreoretinal interface abnormality. Methods: A 49-year-old man presented for his annual ocular examination with no specific ocular complaints. He had a history of retinal detachment in the left eye, which was treated years prior with vitrectomy and scleral buckle. During a routine follow-up, the patient was discovered to have a full-thickness MH. Optical coherence tomography revealed the formation of an MH with spontaneous closure after 3 months without intervention. One month later, the MH recurred but once again closed spontaneously over 4 months. Results: The patient remained asymptomatic during the entire follow-up without any symptoms, vision changes, or therapeutic intervention. Conclusions: To our knowledge, this is the first known case report of recurrent spontaneous opening and closure of an MH in the absence of any vitreoretinal interface abnormality, as revealed by macular optical coherence tomography imaging.

Abstract
This is a cross-sectional, prospective study of a population of black diabetic participants without diabetic retinopathy aimed to investigate optical coherence tomography angiography (OCTA) characteristics and correlations with systemic diseases in this population. These parameters could serve as novel biomarkers for microvascular complications; especially in black populations which are more vulnerable to diabetic microvascular complications. Linear mixed models were used to obtain OCTA mean values ± standard deviation and analyze statistical correlations to systemic diseases. Variables showing significance on univariate mixed model analysis were further analyzed with multivariate mixed models. 92 eyes of 52 black adult subjects were included. After multivariate analysis; signal strength intensity (SSI) and heart disease had statistical correlations to superficial capillary plexus vessel density in our population. SSI and smoking status had statistical correlations to deep capillary plexus vessel density in a univariate analysis that persisted in part of the imaging subset in a multivariate analysis. Hyperlipidemia; hypertension; smoking status and pack-years; diabetes duration; creatinine; glomerular filtration rate; total cholesterol; hemoglobin A1C; and albumin-to-creatinine ratio were not significantly associated with any OCTA measurement in multivariate analysis. Our findings suggest that OCTA measures may serve as valuable biomarkers to track systemic vascular functioning in diabetes mellitus in black patients.

Abstract
The aim of this study was to demonstrate the sensitivity of Optical coherence tomography (OCT) in detection of geographic atrophy (GA) secondary to exudative age related macular degeneration (AMD). In this retrospective case series study 77 patients (53% female, with mean ± standard deviation [SD] of 82.6±9.3 years) with 97 eyes (45 OS [left eyes]/52 OD [right eyes]) were included. This was a retrospective review of the charts of patients who presented with exudative AMD at the Pitié Salpetrière Hospital, Paris, France, between December 2016 and August 2017 that received intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) therapies. At baseline, following biomicroscopy examination, multimodal imaging was performed including, fluorescein angiography (FA), fundus auto-fluorescence (FAF), spectral domain optical coherence tomography (SD-OCT) and indocyanine green angiography (ICGA). During the follow-up, SD-OCT with/without FAF and FA were performed for each patient at 6, 12 and 18 months. For investigation of the prevalence of GA in eyes undergoing intravitreal injections with anti-VEGF therapy, FAF and SD-OCT images were qualitatively reviewed by four independent observers (two graders per group). Kappa coefficient of Cohen was calculated to determine agreement between the graders. The kappa coefficient of Cohen, for inter-rater agreement in the evaluation of FAF images was 0.468, indicating a moderate agreement between the first and second raters. Thus, the sensitivity and specificity of FAF for the diagnosis of GA were 70% and 57%, respectively. If atrophy was assessed with SD-OCT image analysis, the kappa coefficient for inter-rater agreement was 0.846, implying an acceptable agreement between both readers. The sensitivity and specificity of SD-OCT were 93% and 58% respectively. In conclusion, SD-OCT image analysis was more sensitive than FAF for identifying GA in patients treated for exudative AMD.

Abstract
INTRODUCTION Current screening recommendations for chloroquine (CQ) and hydroxychloroquine (HCQ) retinopathy are based on central 10°C static perimetry and a high-resolution SD-OCT with a special attention to the inferior part of the macula where the toxicity usually starts by ellipsoid zone disruption. However, Melles and Marmor, have recently shown a great variability in the topography of the initial toxicity observed among various ethnicities, which is important to keep in mind so as not to miss early toxicity in certain subgroups of patients. METHODS Review of the literature. RESULTS Ethnic differences have been shown regarding the topography of the initial retinal toxicity of CQ and HCQ, particularly between Caucasian and Asian subjects. In Caucasians, the first signs of toxicity are more often localized in the inferior para-foveal area associated with a decrease in retinal sensitivity in the upper 10°C visual field. However, in Asian subjects, the first signs of toxicity appear more pericentral (still inferior) with an extramacular pattern that could be missed by the usual 10°C visual field screening. DISCUSSION/CONCLUSION The pathophysiology of these ethnic differences is unknown and may be due to distinct genetic predisposition to CQ and HCQ toxicity. Screening strategies should be adjusted to the ethnicity and performed in Asian subjects with larger visual fields (30°C), along with SD-OCT, looking for ellipsoid disruption≥8°C from the fovea. The recognition of this pericentral topography and an adjusted screening protocol should avoid late diagnosis in Asians treated with CQ and HCQ.

PURPOSE To evaluate the changes of outer retinal tubulations (ORTs) as seen on spectral-domain optical coherence tomography (SD OCT) in eyes with neovascular age-related macular degeneration (AMD) where treatment was switched from intravitreal ranibizumab to intravitreal aflibercept. METHODS This was a prospective study of eyes diagnosed with neovascular AMD and previously treated with >6 intravitreal ranibizumab injections and switched to aflibercept, conducted at a single centre (Department of Ophthalmology at Pitié Salpetriere Hospital, Paris VI University) from January to July 2015. Before and after treatment was switched from ranibizumab to aflibercept, SD-OCT was used to evaluate the presence of ORTs. Additional assessments in this patient group included best-corrected visual acuity (BCVA), fluorescein angiography (FA), indocyanine green angiography (ICGA). Changes in pigment epithelium detachments (PED), presence of intraretinal cysts, and presence of subretinal fluid (SRF) were also noted. RESULTS Twenty-four eyes of 24 consecutive patients (15 female/nine male, mean age 70 years) diagnosed with neovascular AMD and previously treated with >6 intravitreal ranibizumab injections and switched to aflibercept were included in the analysis. After receiving aflibercept, patients were followed for a mean of 6.1 months. Prior to treatment switch, 97 % of eyes showed ORTs, while after treatment switch to aflibercept, at the end of the study period, 75 % had ORTs (p = 0.219). Changes in BCVA (LogMAR) were not statistically significant (1.16 ± 0.44 to 1.18 ± 1.06, p = 0.12), however, a significant reduction in central macular thickness (CMT) (from 406 μm ± 112 to 263 μm ± 68, p = 0.001), PED (from 70.8 % to 41.7 % , p = 0.016), presence of intraretinal cysts (from 83.3 % to 33.3 %, p = 0.002) and SRF (from 91.7 % to 25 %, p = 0.001 ) were noted. CONCLUSION After switching from ranibizumab treatment to aflibercept, ORTs remained present in 75 % of eyes, and significant reductions in CMT, PED, and SRF, and presence of intraretinal cysts were observed.

Abstract
Macular edema (ME) may complicate anterior, intermediate, and posterior uveitis, which may be because of various infectious, neoplastic or autoimmune etiologies. BRB breakdown is involved in the pathogenesis of Uveitic ME (UME). Optical coherence tomography has become a standard tool to confirm the diagnosis of macular thickening, due to its non-invasive, reproducible, and sensitive features. Retinal fluorescein and indocyanine green angiography is helpful to study the macula and screen for associated vasculitis, detect ischemic areas and preretinal, prepapillary or choroidal neovascular complications, and it may provide information about the etiology and be needed to assess the therapeutic response. UME due to an infection or neoplastic infiltration may require a specific treatment. If it remains persistent or occurs in other etiologies, immunomodulatory treatments may be needed. Intravitreal, subconjunctival, or subtenon corticosteroids are widely used. Their local use is contraindicated in glaucoma patients and limited by their short-lasting action. In case of bilateral sight-threatening chronic posterior uveitis, systemic treatments are usually needed, and corticosteroids are used as the standard first-line therapy. In order to reduce the daily steroid dose, immunosuppressive or immunomodulatory agents may be added, some of them being now available intravitreally. Ongoing prospective studies are assessing biotherapies and immunomodulators to determine their safety and efficacy in this indication.

Abstract
Modern retinal drug therapy is a result of the recent challenges and breakthroughs in chemistry, physics, genetics, cell biology and biotechnologies. Specific pharmaceutical and pharmacokinetic characteristics of a drug are of major importance and contribute to its ability to penetrate targeted ocular tissues in order to result in effective therapeutic concentrations. In addition, the drugs should maintain a prolonged time of activity and be safe with minimal local and systemic toxicity. The transporter vehicle or drug delivery system is crucial in order to enhance ocular tissue penetration and establish controlled drug release. Administration methods should be local, thereby reducing systemic side effects, and, ideally, treatment should be noninvasive. Within the group of so-called classic therapies, the use of pharmacologic treatments has become widespread for most severe retinal diseases. Thereby, ocular therapy of diseases like exudative age-related macular degeneration has improved markedly. Moreover, new metabolic pathways have been identified, new molecules have emerged, new synthesis technologies have been discovered, and new formulae conceived. These developments have opened new avenues for limiting disease progression.

Abstract
PURPOSE This study was designed to evaluate and compare the efficacy of early treatment of CRVO with either hemodilution by erythrocytopheresis or intravitreal (IVT) ranibizumab, or both. MATERIAL AND METHODS A multicentric prospective randomized study including patients with CRVO for less than 1 month was designed. Patients were randomized into 3 treatment groups: hemodilution (HD group), 3 monthly intravitreal injections of ranibizumab followed by PRN treatment (IVT group), or combined treatment (IVT+HD group). A monthly evaluation during a 6-month follow-up included best-corrected visual acuity (BCVA) and macular thickness measurements with OCT. Fluorescein angiography was performed at baseline, month 2 and month 6. Local and systemic tolerability of the different treatments were also compared. RESULTS Forty-four CRVO patients were included between February 2010 and June 2013: 20 in the IVT group, 13 in the HD group and 11 in the HD+IVT group. The mean duration of CRVO at baseline was 10 days and 16 days at the time of treatment without any significant difference between groups. Retinal ischemia was present at baseline in 40% of eyes in each group. After a 6-month follow-up, no difference between the 3 groups was observed in BCVA (10.5 ETDRS letters, 14.6 and 14.1 in the IVT group, HD group and IVT+HD group respectively, P=0.726) or in macular thickness (398 μ, 440 μ and 379 μ respectively, P=0.465). The time until treatment from CRVO onset, ranging from 1 to 35 days, was not correlated to final outcomes. No significant difference in the mean number of IVT (3.2 in the IVT+HD group vs 3.7 in the IVT group) was observed at 6 months. CONCLUSION No difference in BCVA nor in macular thickness was seen at M6 between the study groups. The duration of CRVO at the time of the initiation of the treatment was not correlated to better visual outcomes. Therefore, etiologic treatment with HD can still be proposed as a first-line treatment in young patients, which allows delaying or avoiding the IVT treatment and its potential side effects. Anti-VEGF IVT still remains an effective option in every case and can be started one month after the beginning of the CRVO.

Abstract
PURPOSE To evaluate the impact of traditional French summer vacation on visual acuity and spectral domain-optical coherence tomography (SD-OCT) of Wet AMD patients being treated with intravitreal Ranibizumab. METHODS This was a consecutive, comparative, single-centre, prospective analysis. All patients who were being treated with intravitreal injection of 0.5 mg ranibizumab at Cergy Pontoise Hospital, Department of Ophthalmology between July 2013 and September 2014 were included. Patients were divided into two groups: (A) patients who skipped one ranibizumab intravitreal injection during holidays, and (B) patients who received injection during their holidays. Evaluations occurred prior to traditional holiday (baseline) and 2 months later, consisting of BCVA using ETDRS, and a complete ophthalmic examination that included slit-lamp biomicroscopy, fundus examination, fluorescein angiography (FA), indocyanine green angiography (ICGA), and spectral domain-optical coherence tomography (SD-OCT). All patients were being treated with PRN anti-VEGF regimen and criteria for reinjection included a visual acuity loss >5 ETDRS letters and/or an increase of central retinal thickness, presence of subretinal fluid, intraretinal fluid, or pigment epithelium detachment. If reinjection criteria were not met, patients were advised to return in 4 weeks. RESULTS The mean visual acuity change was -0.071 ± 0.149 (LogMAR) in group A and + 0.003 ± 0.178 in group B (P = 0.041). At the second visit (2 months after preholidays visit), 61.8% of patients in group A had SRF and/or intraretinal cysts, and only 27.6% of patients in group B. There was a significant difference in the persistence of fluid between the two groups (P = 0.007, χ(2)-test). CONCLUSION This cases series demonstrated the detrimental impact of holidays on visual acuity in patients treated with ranibizumab for AMD, which, in spite of their treatment regimen, still leave in vacation. Therefore, it is important to convey the message of treatment adherence to patients, despite their need of holidays.

Abstract
Macular edema may complicate anterior, intermediate, and posterior uveitis, which may be due to various infectious, tumoral, or autoimmune etiologies. Breakdown of the internal or external blood-retinal barrier is involved in the pathogenesis of inflammatory macular edema. Optical coherence tomography has become standard in confirming the diagnosis of macular thickening, due to its non-invasive, reproducible and sensitivity characteristics. Fluorescein and indocyanine green angiography allows for, in addition to study of the macula, screening for associated vasculitis, detection of ischemic areas, easy diagnosis of preretinal, prepaillary or choroidal neovascular complications, and it can provide etiological information and may be required to evaluate the therapeutic response. Treatment of inflammatory macular edema requires specific treatment in cases of infectious or tumoral etiologies. If it remains persistent, or occurs in other etiologies, anti-inflammatory treatments are needed. Steroid treatment, available in intravitreal, subconjunctival and sub-Tenon's routes, are widely used. Limitations of local use include induced cataract and glaucoma, and their short-lasting action. Such products may reveal retinal infection. Thus, bilateral chronic sight-threatening posterior uveitis often requires systemic treatment, and steroids represent the classic first-line therapy. In order to reduce the daily steroid dose, immunosuppressant or immunomodulatory drugs may be added. Certain of these compounds are now available intravitreally.

Abstract
PURPOSE To investigate the multimodal morphological features in the different stages of Best vitelliform macular dystrophy (VMD) in subjects harboring mutations in the BEST1 gene, and their changes during the progression of the disease. METHODS In this retrospective observational study performed between January 2007 and December 2012, 21 patients (42 eyes) with Best VMD from eight families with the BEST1 mutation were included. Best-corrected visual acuity (BCVA), fundus autofluorescence (FAF), and spectral domain optical coherence tomography (SDOCT) were evaluated at study entry and at last visit. RESULTS The mean age of patients was 26.3±17.4 years. Seven new missense mutations in BEST1 were identified. Mean follow-up was 41.1±18.5 months. Mean BCVA was 0.34±0.34 LogMAR at study entry and 0.32±0.33 LogMAR at last follow-up visit (p = 0.2). The overall lesion area on FAF increased from 6.62±4.9 mm² to 7.34±6.1 mm² (p = 0.05). At study entry, on SD-OCT, photoreceptor inner segment ellipsoid portion (ellipsoid zone, EZ) was normal in 15 eyes, disrupted in 14 eyes, and absent in 13 eyes. In two eyes, EZ changed from normal to disrupted during follow-up. Three eyes of three patients showing pseudohypopyon lesions at study entry progressed to vitelliruptive lesions at the last follow-up visit. Three eyes of three patients showing vitelliruptive lesion at study entry reverted to pseudohypopyon lesion with overall enlargement of the lesion size. CONCLUSIONS Multimodal analysis allowed documenting a continuous material accumulation and reabsorption in Best VMD progression. Blue FAF and SD-OCT could represent noninvasive imaging techniques to monitor Best VMD.

Abstract
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.

Abstract
PURPOSE To analyze the internal structure of fibrovascular pigment epithelial detachment (FV-PED) due to AMD using en face enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT). METHODS Thirty-eight consecutive patients presenting with FV-PED due to AMD were enrolled in this study. Retinal images were automatically obtained with a spectral domain (SD) OCT instrument; the typical inverted 97 sections at 30-μm intervals, each comprised of nine averaged B-scans, were acquired in less than 60 seconds. The resultant images of en face cross-sections of the choroid (C-scans) were compared with indocyanine green angiography (ICGA) images, currently the only technique available for directly viewing occult choroidal neovascularization (CNV). RESULTS Thirty-eight eyes of 38 consecutive patients (27 females and 11 males, mean age 76.7±3 years) were studied. In all 38 eyes, ICGA allowed visualization of the CNV within the FV-PED. In 30 eyes, en face EDI-OCT revealed what appeared to be the hyperreflective course of presumed CNV, which was located just beneath the detached retinal pigment epithelium; this was confirmed by comparative analysis of the extent of hyperreflective lesions on en face EDI-OCT images and that of the neovascular network on ICGA. An area of homogeneous hyporeflectivity, consistent with serous exudation, separated the CNV from the Bruch's membrane and the choroid. In the remaining eight eyes, en face EDI-OCT revealed homogenous hyperreflectivity, consistent with fibrous tissue that partially hid the neovascular network. CONCLUSIONS Noninvasive en face EDI-OCT technique enables visualization and localization of the entire branching neovascular network of CNV within FV-PED without dye injection.

Abstract
PURPOSE The purpose of this study was to understand clinical significance of near-infrared reflectance (NIR), blue fundus autofluorescence (FAF) and near-infrared autofluorescence (NIA) in dry age-related macular degeneration (AMD), by correlation with fluorescein angiography (FA) and cross-sectional spectral domain optical coherence tomography (SD OCT). METHODS We evaluated 110 eyes (62 patients, mean age: 64 ± 8 years) diagnosed with dry AMD between January 2010 and December 2010, which underwent NIR (λ = 830 nm), FAF and FA (excitation λ = 488 nm; emission λ > 500 nm), NIA (excitation λ = 787 nm; emission λ > 800 nm), and simultaneous SD OCT scanning using a combined confocal scanning laser ophthalmoscope/SD OCT device (Spectralis HRA + OCT; Heidelberg Engineering, Heidelberg, Germany). RESULTS Drusen showed variable increased/decreased NIR, FAF, NIA and FA, which corresponded to variable increased/decreased thickness of the retinal pigment epithelium (RPE) and possible presence of subretinal deposits on SD OCT. Geographic atrophy (GA) was present in 43/110 eyes (39.0%) and showed increased NIR and fluorescence (FA), absent FAF and NIA, and loss of RPE on SD OCT. The hyperautofluorescence of the GA margin was never larger in FAF than that in NIA, while in 16.2% of cases, it was larger in NIA than that in FAF and corresponded to mild choroidal hyperreflectivity on SD OCT. CONCLUSIONS Simultaneous recording of SD OCT scans provided ultrastructural data for the evaluation of NIR, FAF, NIA and FA in dry AMD. Near-infrared autofluorescence might detect earlier than FAF areas of RPE cell loss at the GA margin.

Abstract
PURPOSE To analyze reticular pseudodrusen progression using spectral domain-optical coherence tomography (SD-OCT). METHODS Thirty-three consecutive patients (48 eyes) underwent SD-OCT using the eye-tracked follow-up protocol 24 ± 2 months after baseline examination. Each pair of B-scans (only one per eye was evaluated among those showing pseudodrusen progression) was compared with respect to pseudodrusen appearance and retinal layer structure. Stage 1 pseudodrusen was defined as granular material between the RPE and the inner segment/outer segment (IS/OS), stage 2 as mounds of material sufficient to alter the contour of the IS/OS, stage 3 as thicker material adopting a conical appearance and breaking through the IS/OS, and stage 4 as fading of the material because of reabsorption and migration within the inner retinal layers. RESULTS A total of 78 pseudodrusen (detected on the 48 analyzed B-scans, and counting for a mean of 2.3 pseudodrusen per scan) showed progression over a mean of 23.9 ± 1.2 months. All 58 pseudodrusen (100%) graded as stage 1 at baseline examination progressed to stage 2. Thirteen of 16 pseudodrusen (81.3%) graded as stage 2 at baseline examination progressed to stage 3, and three (18.7%) progressed to stage 4. All four pseudodrusen (100%) graded as stage 3 at baseline examination progressed to stage 4. Among pseudodrusen that were stage 3 or 4 at follow-up (n = 20), 100% had IS/OS disruption whereas 12.1% (n = 7) had IS/OS disruption at stage 1 or 2 (n = 58) (OR, 1.736; 95% CI, 1.02-2.43). CONCLUSIONS The frequency of stage changes over time suggest that reticular pseudodrusen are dynamic pathologic structures.

Abstract
PURPOSE To analyze choroidal changes associated with reticular pseudodrusen by indocyanine green angiography (ICGA) and enhanced depth imaging spectral-domain optical coherence tomography (EDI SD-OCT). METHODS Twenty-two consecutive patients (22 eyes) with reticular pseudodrusen, and without medium/large drusen, underwent ICGA and EDI OCT. Twenty-one age- and sex-matched subjects (21 eyes) with early age-related macular degeneration (AMD), and without pseudodrusen, also underwent EDI OCT. RESULTS Mean age of patients with reticular pseudodrusen and with early AMD was 82.5 ± 0.9 and 79.3 ± 4.4 years of age, respectively (P = 0.9), and 59.0% and 76.2% were females, respectively (P = 0.7). On ICGA, reticular patterns appeared as hypofluorescent, not overlying the large choroidal vessels. Areas of iso/hyperfluorescence on ICGA, occurring adjacently to reticular patterns, appeared on OCT as subretinal deposits. The mean subfoveal choroidal thickness was significantly reduced in the group with reticular pseudodrusen compared with that in the control group (174.6 ± 10.1 and +241.4 ± 16.5, respectively; P < 0.001). At all measurement points, but the 3000 μm superior to the fovea, the choroidal thickness of eyes with reticular pseudodrusen appeared thinner than that of the control group. Interestingly, the choroid of eyes with reticular pseudodrusen appeared thicker at 3000 μm superior to the fovea compared with that at all other measurement points. CONCLUSIONS It was shown that the reticular patterns appeared as hypofluorescent lesions on ICGA, closely abutting, but not overlying the large choroidal vessels. In eyes with reticular pseudodrusen, EDI OCT revealed an overall thinned choroid.

Abstract
PURPOSE To describe the natural course of adult-onset foveomacular vitelliform dystrophy using spectral-domain optical coherence tomography (SD-OCT). DESIGN Retrospective study. METHODS We reviewed the charts of all consecutive patients with adult-onset foveomacular vitelliform dystrophy who underwent SD-OCT at baseline and at least 12 months later (last visit). Main outcome measures were changes of clinical and SD-OCT features over time. RESULTS Forty-six eyes (31 patients, 15 male and 16 female; mean age 74.6 ± 8.2 years) were included. Follow-up was 16.2 ± 6 (range, 12-30) months. Visual acuity (VA) reduced from 0.32 ± 0.22 logMAR at baseline to 0.39 ± 0.28 logMAR at last visit (P=.03). The stage of the disease was vitelliform in 28 eyes (60.8%), pseudohypopyon in 7 eyes (15.2%), vitelliruptive in 11 eyes (23.9%) at baseline; vitelliform in 23 eyes (50%), pseudohypopyon in 5 eyes (10.9%), vitelliruptive in 13 eyes (28.2%), and atrophic in 5 eyes (10.9%) at last visit. Stabilization of the disease stage, inner segment/outer segment (IS/OS) interface status, and lesion reflectivity on SD-OCT determined no VA changes (P>.05), while their worsening determined a reduction of VA (P=.03). In eyes that presented a progression of the disease stage, mean central macular thickness, maximal thickness of the lesion, and maximal width of the lesion showed a significant change (from 404.1 ± 107.6 μm to 246.1 ± 74.0 μm, P = .004; from 277.0 ± 80.8 μm to 105.3 ± 92.3 μm, P=.001; from 2324.2 ± 1250.3 μm to 1751.0 ± 858.3 μm, P = .04, respectively). CONCLUSIONS In adult-onset foveomacular vitelliform dystrophy, progression of the lesion stage (partial/complete resorption of the material) is generally accompanied by IS/OS interface disruption/loss and visual impairment.

Abstract
PURPOSE To investigate the prevalence and clinical significance of cystoid macular degeneration in eyes that underwent intravitreal ranibizumab injections for exudative age-related macular degeneration. DESIGN Retrospective, interventional case series. METHODS We reviewed the charts of 56 consecutive patients (19 male, 37 female; mean age ± standard deviation, 80.81 ± 4.8 years) with exudative age-related macular degeneration who received the last intravitreal ranibizumab injection at least 6 months before and were judged to have a fibroatrophic scar without signs of progression by fluorescein angiography or spectral-domain optical coherence tomography. Main outcome measures were the estimated prevalence and clinical significance of cystoid macular degeneration. RESULTS Twenty-two eyes showed various combinations of degenerative pseudocysts, whereas 34 eyes did not show any pseudocysts. The 95% confidence interval for the prevalence estimate was 36.98% to 41.02%. Degenerative pseudocysts appeared square-shaped, did not change their overall appearance over time, and were located just below the internal limiting membrane in 11 eyes (50%), in the inner nuclear layer in 16 eyes (72.7%), in the outer nuclear layer in 8 eyes (36.3%), and in all the retinal layers in 6 eyes (27.2%). Best-corrected visual acuity improved in eyes with and without degenerative pseudocysts and decreased significantly in eyes with degenerative pseudocysts (P = .03). Mean central macular thickness decreased significantly (P < .001) to 324.1 μm and to 328.2 μm in eyes and without degenerative pseudocysts, respectively. CONCLUSIONS Cystoid macular degeneration represents a well-distinguished clinical entity that may be detected in exudative age-related macular degeneration eyes showing a posttreatment fibroatrophic scar and should not be considered as a manifestation of choroidal neovascularization activity.

Abstract
AIM To describe a patient with type 3 choroidal neovascularization (CNV) associated with fundus flavimaculatus (FFM), who underwent treatment with intravitreal ranibizumab. METHODS A 78-year-old woman diagnosed with FFM presented at our department complaining of decreased vision and metamorphopsia in her left eye. Upon a complete ophthalmologic examination, including best corrected visual acuity (BCVA), fundus autofluorescence, fluorescein angiography (FA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT), the patient was diagnosed with type 3 CNV associated with FFM, and was submitted to intravitreal ranibizumab injections at monthly intervals. RESULTS Six months after 3 monthly injections of ranibizumab, the patient's BCVA improved from 20/64 to 20/32. FA and ICGA revealed a type 3 CNV closure, and the SD-OCT scan showed a fibrous scar replacing the type 3 CNV, with resolution of serous retinal detachment. CONCLUSION This case represents the first demonstration of type 3 CNV associated with FFM. Based on our findings, intravitreal ranibizumab may be considered as a therapeutic option for this rare association.
