Abstract
PURPOSE To review a case of bilateral diffuse chorioretinopathy as a presenting sign of juvenile dermatomyositis (JDM) and review the literature regarding retinal manifestations associated with this disease. METHODS Review of case record and literature regarding retinal manifestations related to juvenile dermatomyositis. RESULTS A 13-year-old girl presented with bilateral diffuse chorioretinopathy as the presenting sign of juvenile dermatomyositis. A review of the literature suggests that retinopathy associated with JDM is a rare finding that is symptomatic to patients and often responds to systemic treatment of juvenile dermatomyositis. This is also the first documented case of paracentral acute middle maculopathy in the setting of juvenile dermatomyositis. CONCLUSION Chorioretinopathy is a rare finding in juvenile dermatomyositis. While all patients with JDM likely do not warrant screening ophthalmologic examinations, any patient who has visual symptoms should have a careful dilated examination to evaluate for retinopathy or steroid-induced cataracts.

Abstract
IMPORTANCE Comparisons of monthly vs treat-and-extend anti-vascular endothelial growth factor (anti-VEGF) regimens for macular edema from central retinal vein occlusion or hemiretinal vein occlusion is needed. OBJECTIVE To compare visual acuity letter score and central subfield thickness outcomes of participants in the Study of Comparative Treatments for Retinal Vein Occlusion 2 (SCORE2) trial who then received either monthly injections or treat-and-extend (TAE) regimens of aflibercept or bevacizumab after a good response at month 6. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial enrolled participants from 66 private practice or academic centers in the United States. All participants had macular edema associated with central retinal vein occlusion or hemiretinal vein occlusion, had enrolled in the SCORE2 trial, and had a protocol-defined good response to monthly injections in the first 6 months of the trial. Participants initially assigned to receive monthly aflibercept were randomized to aflibercept on a monthly or TAE schedule, and participants initially assigned to receive monthly injections of bevacizumab were randomized to receive bevacizumab on a monthly or TAE schedule. The first participant was randomized in the SCORE2 trial on September 17, 2014, and the last month 12 visit occurred on October 24, 2016. MAIN OUTCOMES AND MEASURES Change from month 6 to month 12 in best-corrected electronic visual acuity letter score (per the Early Treatment Diabetic Retinopathy Study). RESULTS The 293 participants had a mean (SD) age of 68.9 (11.9) years; 127 (43.3%) were female. Of these, 79 were randomized to aflibercept on a monthly schedule, 80 to aflibercept on a TAE schedule, 67 to monthly bevacizumab, and 67 to bevacizumab on a TAE schedule. Mean treatment group difference (the change in visual acuity letter score in the monthly group minus the change in the TAE group) from month 6 to month 12 was 1.88 (97.5% CI, -1.07 to 4.83; P = .15) for aflibercept and 1.98 (97.5% CI, -1.08 to 5.03; P = .15) for bevacizumab. In the aflibercept arm, the mean number of injections between months 6 and 11 was 5.8 in the monthly injection group (95% CI, 5.6 to 5.9) and 3.8 in the TAE group (95% CI, 3.5 to 4.1; P < .001); in the bevacizumab arm, the mean number of injections was 5.8 (95% CI, 5.6 to 5.9) in the monthly group and 4.5 in the TAE group (95% CI, 4.2 to 4.8; P < .001). CONCLUSIONS AND RELEVANCE One to 2 fewer injections of aflibercept or bevacizumab were given to the TAE groups than the monthly groups in months 6 to 12 for macular edema associated with central retinal or hemiretinal vein occlusion. Because of wide confidence intervals on the differences between the groups, caution is warranted before concluding that the regimens are associated with similar vision outcomes.

Abstract
PURPOSE To assess macular thinning in individuals with prediabetes or type 2 diabetes without diabetic retinopathy (DM2 w/o DR) compared with individuals with normal glucose metabolism (NGM). METHODS Using spectral domain optical coherence tomography (SD-OCT), we measured macular thickness in six subfields as defined by the Early Treatment Diabetic Retinopathy Study (ETDRS) in 1838 participants from The Maastricht Study, a population-based cohort study (mean age 59 ± 8 years, 49% men, 1087 NGM, 279 prediabetes, 472 DM2 w/o DR). Multivariable linear regression was used to assess the association between macular thickness and glucose metabolism status. RESULTS After adjustment for age, sex and spherical equivalent, individuals with prediabetes showed a significant decrease in pericentral superior macular thickness [β = -2.14 μm (95% confidence interval (CI): -4.24 to -0.03), p < 0.05] compared with individuals with NGM. In individuals with DM2 w/o DR, the fovea [β = -4.05 μm (95% CI: -6.30 to -1.79), p < 0.001] and the four pericentral quadrants (range: β = -4.64 to -5.29 μm, p < 0.001) were significantly thinner compared with individuals with NGM. There was a significant linear trend of macular thinning with severity of glucose metabolism status in five subfields (p < 0.001). CONCLUSION Macular thickness is reduced in prediabetes and a greater reduction occurs in DM2, even before DR is clinically present. About half of the thinning observed in DM2 w/o DR was already found in prediabetes. Generalized thinning of the macula could be related to thinning of the temporal side of the optic nerve head through the connecting papillo-macular bundle.

Abstract
AMD pathobiology was irreversibly changed by the recent discovery of extracellular cholesterol-containing deposits in the subretinal space, between the photoreceptors and retinal pigment epithelium (RPE), called subretinal drusenoid deposits (SDDs). SDDs strikingly mirror the topography of rod photoreceptors in human macula, raising the question of whether an equivalent process results in a deposition related to foveal cones. Herein we propose that AMD's pathognomonic lesion-soft drusen and basal linear deposit (BLinD, same material, diffusely distributed)-is the leading candidate. Epidemiologic, clinical, and histologic data suggest that these deposits are most abundant in the central macula, under the fovea. Strong evidence presented in a companion article supports the idea that the dominant ultrastructural component is large apolipoprotein B,E-containing lipoproteins, constitutively secreted by RPE. Lipoprotein fatty acids are dominated by linoleate (implicating diet) rather than docosahexaenoate (implicating photoreceptors); we seek within the retina cellular relationships and dietary drivers to explain soft druse topography. The delivery of xanthophyll pigments to highly evolved and numerous Müller cells in the human fovea, through RPE, is one strong candidate, because Müller cells are the main reservoir of these pigments, which replenish from diet. We propose that the evolution of neuroglial relations and xanthophyll delivery that underlie exquisite human foveal vision came with a price, that is, soft drusen and sequela, long after our reproductive years.

Eichenbaum, DA, Duerr, E, Patel, HR, Pollack, SM
Ophthalmic surgery, lasers & imaging retina. 2018;(11):e191-e197
Abstract
BACKGROUND AND OBJECTIVE Compare fixed monthly dosing of ranibizumab to treat-and-extend (T&E) ranibizumab during a period of 24 months for diabetic macular edema (DME) treatment. PATIENTS AND METHODS Single-center, randomized, prospective pilot study that included 20 eyes of 20 subjects. Patients' best-corrected visual acuity (BCVA) was less than or equal to 20/40 and central foveal thickness on spectral-domain optical coherence tomography was greater than 325 µm. Intravitreal ranibizumab was dosed monthly or by protocol-specified treat-and-extend. Primary outcome was mean change in mean BCVA. Institutional review board approval was obtained. RESULTS At month 24 (M24), there was a mean 8.3-letter gain in the monthly treatment group and an 8.5-letter gain in the T&E group (P = .082; 90% confidence interval). The average change from baseline BCVA was not statistically significantly different at any timepoint. At M24, the median number of injections in the monthly and T&E groups were 22.5 and 18.5, respectively (P = .287). CONCLUSIONS Visual acuity with monthly dosing appears equivalent to T&E dosing during the course of 24 months. There was a trend toward a lower injection burden in the T&E arm.

Abstract
PURPOSE Our purpose was to compare the impact in diabetic macula edema (DME) of two intravitreal drugs (0.5 mg ranibizumab vs. 8 mg triamcinolone) on changes in retinal morphology in spectral-domain optical coherence tomography (SD OCT) images, color fundus photography (CF) and fluorescein angiography (FA) images during a 1-year follow-up. METHODS Post hoc analysis was conducted of morphologic characteristics in OCT, FA and CF images of eyes with a center involving DME that were included in a prospective double-masked randomized trial. Eligible patients were divided at random into two groups receiving either pro re nata treatment with 0.5 mg ranibizumab or 8 mg triamcinolone after a fixed loading dose. OCT and CF images were acquired at monthly visits and FA images every three months. RESULTS Twenty-five eyes of 25 patients (ranibizumab: n = 10; triamcinolone: n = 15) were included in this study. Patients treated with ranibizumab showed better visual acuity results after 12 months than patients receiving triamcinolone (p = 0.015) although edema reduction was similar (p = 0.426) in both groups. The initial effect on macular edema shedding after a single ranibizumab injection could be amplified with the following two injections of the loading dose. After a single injection of triamcinolone the beneficial initial effect on the macula edema faded within 3 months. Subretinal fluid and INL cystoid spaces diminished early in the course of treatment while fluid accumulation in the ONL seemed to be more persistent in both treatment arms. In FA, the area of leakage diminished significantly in both treatment arms. After repeated injections the morphologic OCT and FA characteristics of the treatment arms converged. CONCLUSIONS Despite the higher dosage of triamcinolone, both therapies were safe and effective for treating diabetic macular edema. Fluid accumulation in the INL and subretinal space was more responsive to therapy than fluid accumulation in the ONL. Clinicaltrials.gov : NCT00682539.

Retinal complications of gout: a case report and review of the literature.
Jiang, Y, Brenner, JE, Foster, WJ
BMC ophthalmology. 2018;(1):11
Abstract
BACKGROUND There have been few reported findings of posterior segment complications of gout. While exudative lesions, an increased risk of macular degeneration, and vascular occlusions have been previously reported, to our knowledge, refractile macular lesions have not been reported in a patient with chronic uncontrolled gout. CASE PRESENTATION Highly refractile, crystal-like lesions were found in the macula of a 62 year old male patient with chronically uncontrolled gout. The lesions appeared at the termination of retinal arterioles and were located at the level of the retinal pigment epithelium. The lesions did not stain with fluorescein and were associated with larger areas geographic atrophy. Review of the patient's blood tests revealed well-controlled vasculopathic risk factors. Fundus appearance and best-corrected visual acuity remained stable over 12 months of follow-up during which the uric acid levels were well controlled. CONCLUSION Retinopathy may be associated with chronically uncontrolled gout and patients with visual complaints should undergo a dilated examination in addition to the typical anterior segment slit-lamp exam.

Abstract
PURPOSE Identify predictors for response to anti-vascular endothelial growth factor (VEGF) therapy in patients with neovascular (wet) age-related macular degeneration (nAMD). METHODS Retrospective, post hoc analysis of VIEW 1/2. Patients were randomized 1:1:1:1 to 0.5 mg intravitreal aflibercept (IVT-AFL) injection every 4 weeks (0.5q4); 2 mg IVT-AFL every 4 weeks (2q4); 2 mg IVT-AFL every 8 weeks (2q8) after an initial three injections at weeks 0, 4 and 8 or 0.5 mg intravitreal ranibizumab every 4 weeks (0.5q4). RESULTS 1815 patients [IVT-AFL 2q4 (n = 613); IVT-AFL 2q8 (n = 607); ranibizumab 0.5q4 (n = 595)] were included. Baseline demographics/characteristics were evenly balanced. Younger age (49-69 years), lower visual acuity (VA) [10.0-≤45.0 Early Treatment Diabetic Retinopathy Study (ETDRS) letters] and smaller choroidal neovascularization (CNV) size [0.0-≤3.1 disc areas (DA)] at baseline were associated with the most vision gain (≥15 letters) over 52 weeks (all nominal p < 0.0001).Younger age, higher baseline VA (>64.0-≤83.0 letters) and smaller CNV size were associated with a VA ≥20/40 at week 52. Predominantly classic CNV at baseline (nominal p = 0.0007), older age (≥90 years), lower baseline VA (10.0-≤ 45.0 ETDRS letters) and larger CNV size (>10.1-≤32.6 DA) were all associated with a VA ≤20/200 at week 52 (all nominal p < 0.0001). Along with treatment (nominal p < 0.0001), lower VA (p = 0.0166) and smaller central retinal thickness (both nominal p = 0.0190) were predictors for dry retina development. CONCLUSION Younger age, lower VA and smaller CNV size at baseline were all associated with greater vision gains over 52 weeks while younger age, higher VA and smaller CNV size at treatment start were more likely to achieve best-corrected VA 20/40 or better after a year's treatment, suggesting the benefit of early anti-VEGF treatment.

Ophthalmology. 2018;(2):267-275
Abstract
PURPOSE Identification and characterization of patients with diabetic macular edema (DME) are important for individualizing treatment and optimizing outcome. We investigated OCT biomarkers for DME treated by intravitreal dexamethasone (DEX) implant. DESIGN Multicenter, retrospective, observational cohort study. PARTICIPANTS A total of 299 eyes from 284 patients treated with DEX implant for DME (naïve, n = 209; refractory, n = 90). Baseline best-corrected visual acuity (BCVA) was between 0.3 and 1.0 on a logarithm of minimum angle of resolution visual chart. METHODS The OCT scans previous to DEX implants were evaluated for submacular fluid, size and location of cystoid changes, inner segment-outer segment (IS-OS) continuity, quantity and location of hyperreflective foci (HRF), vitreomacular interface abnormalities, and epiretinal membrane. The BCVA and central macular thickness were recorded at baseline and at 1, 2, and 4 months after treatment with DEX implants. Correlations between OCT measures and visual outcome were analyzed using the generalized estimating equations procedure. MAIN OUTCOME MEASURES The correlation between spectral-domain (SD) OCT measures at baseline and BCVA response (mean change from baseline; categorized improvement [<5, 5-9, or ≥10; Early Treatment Diabetic Retinopathy Study letters] in BCVA) after treatment with a DEX implant. RESULTS The presence of subretinal fluid (odds ratio [OR], 1.98; 95% confidence interval [CI], 1.23-3.20; P = 0.01), absence of HRF (OR, 3.66; 95% CI, 1.40-9.62; P = 0.01), and integrity of the IS-OS layer (OR, 2.09; 95% CI, 1.30-3.37; P = 0.003) were all predictive of better visual outcome after treatment with DEX implants. Although eyes with naïve DME gained more vision than refractory eyes (P < 0.001), the predictive value of OCT findings did not differ according to this classification. CONCLUSIONS Spectral-domain OCT is useful in identifying various imaging findings in DME. Among eyes with DME, those with submacular fluid, no HRF, and a continuous IS-OS layer responded better to DEX implants than those without these features. These findings call for further study of combinations of OCT and metabolic biomarkers.

Abstract
PURPOSE To assess layer- and location-specific retinal thickness deficits in autosomal dominant optic atrophy (ADOA) using Spectralis SD-OCT. METHODS This cross-sectional study included 41 ADOA patients with OPA1 exon 28 (2826delT) mutation [age, 8.6-83.5 years; best-corrected visual acuity (BCVA), 8-89 Early Treatment Diabetic Retinopathy Study (ETDRS) letters] and 55 mutation-free first-degree relatives as healthy controls (age, 8.9-68.7; BCVA, 80-99). Participants underwent routine examination and optical coherence tomography (OCT) with segmentation of the whole retina, inner retinal layers (IRL) and outer retinal layers (ORL). Individual segmentation was performed of the perifoveal retinal nerve fibre layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), retinal pigment epithelium (RPE) and the peripapillary RNFL. Combinations of layers and sectors were tested for their diagnostic significance. Only right eye data are presented. Statistical analysis was adjusted for age, gender, spherical equivalent, axial length and family clustering in a mixed model analysis. RESULTS The perifoveal RNFL, GCL, IPL and the peripapillary RNFL were all significantly thinner in ADOA patients than in healthy controls (p < 0.0001). No statistical difference was found for other layers. The most prominent and diagnostically most valuable deficit was found in the GCL (-49.9%) in the 'nasal inner macula' (NIM) sector (-63%). Attenuation of the peripapillary RNFL was most significant in the temporal sector (-58.4%). CONCLUSION In ADOA, retinal ganglion cells are most prominently reduced in the nasal perifoveal area of the GCL, which together with the temporal peripapillary RNFL area serves as the strongest diagnostic OCT marker.
