Abstract
PURPOSE To describe the treatment outcomes and recurrence risk of chronic central serous chorioretinopathy (cCSC) in patients who had complete resolution of subretinal fluid (SRF) after either primary half-dose photodynamic therapy (PDT) or high-density subthreshold micropulse laser (HSML) in the PLACE trial. METHODS This multicentre prospective follow-up study evaluated cCSC patients at 1 year after completion of the PLACE trial. Outcomes included: complete resolution of SRF on OCT, best-corrected visual acuity (BCVA) in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters, retinal sensitivity on microperimetry and a visual function questionnaire (NEI-VFQ25). RESULTS Twenty-nine out of 37 patients who received half-dose PDT and 15 out of 17 patients who received HSML could be evaluated at final visit. At final visit, 93% of the patients treated with half-dose PDT had complete resolution of SRF, compared with 53% of HSML-treated patients (p = 0.006). At final visit, the mean estimate increase in the PDT group compared with the HSML group was + 2.1 ETDRS letters, +0.15 dB for the retinal sensitivity and + 5.1 NEI-VFQ25 points (p = 0.103, p = 0.784 and p = 0.071, respectively). The mean estimated central retinal thickness in the half-dose PDT group was -7.0 µm compared with the HSML group (p = 0.566). The mean estimated subfoveal choroidal thickness in the half-dose PDT group was -16.6 µm compared with the HSML group (p = 0.359). CONCLUSION At 20 months after treatment, cCSC patients successfully treated with half-dose PDT are less likely to have recurrences of SRF compared with those successfully treated with HSML. However, functional outcomes did not differ.

Abstract
PURPOSE To evaluate the impact of cataract surgery on visual and anatomic outcomes in patients with diabetic macular edema treated with intravitreal aflibercept injection (IAI) or laser control and who did not require rescue therapy. DESIGN Post hoc analysis of 2 phase 3 trials, Study of Intravitreal Aflibercept Injection in Patients with Diabetic Macular Edema (VISTA) and Intravitreal Aflibercept Injection in Vision Impairment Due to DME (VIVID). PARTICIPANTS Fifty-four patients (laser treatment, n = 11; IAI, n = 43) who underwent cataract surgery during the study period. METHODS In VISTA and VIVID, patients received IAI 2 mg every 4 weeks, IAI 2 mg every 8 weeks after 5 monthly doses, or laser control through week 100. Starting at week 24, if rescue treatment criteria were met, IAI patients received laser therapy, and laser therapy patients received IAI 2 mg every 8 weeks (after 5 monthly doses). Patients who received rescue treatment before cataract surgery were excluded. MAIN OUTCOME MEASURES Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in the laser control and pooled IAI groups before and after cataract surgery. RESULTS The cumulative incidence of cataract surgery did not depend on treatment group assignment (rate ratio, = 1.517; 95% confidence interval, 0.782-2.944; P = 0.2174). At the last study visit before surgery, BCVA was 62.2 and 56.9 letters and CRT was 342 μm and 301 μm in the laser control and IAI groups, respectively. At the first study visit after cataract surgery, BCVA was improved significantly in both the laser control and IAI groups to 73.5 letters (P = 0.010 compared with last visit before surgery) and 67.2 letters (P < 0.001 compared with last visit before surgery), respectively. Corresponding change in CRT was a modest increase to 364 μm (P > 0.05 compared with last visit before surgery) and 359 μm (P = 0.013 compared with last visit before surgery), respectively. CONCLUSIONS Incidence of cataract surgery was similar in both treatment groups. Despite a modest worsening in CRT after cataract surgery, BCVA was improved in both treatment groups.

Abstract
PURPOSE To evaluate the efficacy of intravitreal aflibercept monotherapy for submacular hemorrhage secondary to neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). METHODS This prospective, phase 4 clinical trial included 29 patients diagnosed with fovea-involving submacular hemorrhage secondary to neovascular AMD (7 patients) or PCV (22 patients). Patients were initially administered 3 monthly aflibercept injections, followed by 1 injection every 2 months. The primary outcome measure was changes in Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA) during the 56-week study period. Other key outcome measures were the proportion of patients who exhibited changes in BCVA of ≥ 15 ETDRS letters from baseline and changes in central retinal thickness (CRT). RESULTS The mean size of hemorrhage was 6.2 ± 4.8-disc-diameter area. The mean BCVA significantly improved from 52.9 ± 17.8 ETDRS letters at week 0 (baseline) to 71.8 ± 16.1 letters at week 56 (P < 0.001). At week 56, improvement in BCVA of ≥ 15 letters was noted in 16 patients (55.2%), whereas none of the patients experienced a loss of ≥ 15 letters. The mean CRT significantly decreased from 498.9 ± 194.2 μm at week 0 to 248.3 ± 45.0 μm at week 56 (P < 0.001). During the study period, retinal break developed in one patient. CONCLUSIONS Intravitreal aflibercept administered every 2 months after the 3 initial monthly doses was found to be an effective and safe treatment method for submacular hemorrhage secondary to neovascular AMD.

Abstract
PURPOSE Choroideremia (CHM) is a rare inherited retinal degeneration resulting from mutation of the CHM gene, which results in absence of functional Rab escort protein 1 (REP1). We evaluated retinal gene therapy with an adeno-associated virus vector that used to deliver a functional version of the CHM gene (AAV2-REP1). METHODS THOR (NCT02671539) is a Phase 2, open-label, single-center, randomized study. Six male patients (51-60 years) with CHM received AAV2-REP1, by a single 0.1-mL subretinal injection of 10 genome particles during vitrectomy. Twelve-month data are reported. RESULTS In study eyes, 4 patients experienced minor changes in best-corrected visual acuity (-4 to +1 Early Treatment Diabetic Retinopathy Study [ETDRS] letters); one gained 17 letters and another lost 14 letters. Control eyes had changes of -2 to +4 letters. In 5/6 patients, improvements in mean (95% confidence intervals) retinal sensitivity (2.3 [4.0] dB), peak retinal sensitivity (2.8 [3.5] dB), and gaze fixation area (-36.1 [66.9] deg) were recorded. Changes in anatomical endpoints were similar between study and control eyes. Adverse events were consistent with the surgical procedure. CONCLUSION Gene therapy with AAV2-REP1 can maintain, and in some cases, improve, visual acuity in CHM. Longer term follow-up is required to establish whether these benefits are maintained.

Abstract
PURPOSE To assess efficacy of intravitreal ranibizumab injections and targeted panretinal photocoagulation (TRP) for radiation retinopathy-related macular edema. DESIGN Phase IIb, prospective, randomized clinical trial. METHODS Setting: Multicenter. SUBJECTS Forty eyes in 40 treatment-naïve patients with radiation-induced macular edema and a resulting decrease in visual acuity ranging between 20/25 and 20/400 (Snellen equivalent). INTERVENTION Patients either received intravitreal 0.5 mg ranibizumab monthly, monthly ranibizumab with TRP, or 3 monthly ranibizumab (loading doses) followed by as-needed (PRN) injections and TRP. After week 52, all subjects entered a treat-and-extend protocol for ranibizumab. MainOutcomeMeasures: Mean Early Treatment Diabetic Maculopathy Study (ETDRS) BCVA change from baseline. RESULTS Mean patient age was 57 years (range, 22-80 years), ETDRS BCVA was 56.7 letters (20/74 Snellen equivalent), and central macular thickness (CMT) was 423 μm (range, 183-826 μm). Thirty-seven patients completed the month 12 visit (92.5%), at which time the change in mean BCVA was +4.0 letters, -1.9 letters, and +0.9 letters in the monthly, monthly plus laser, and PRN plus laser cohorts, respectively. There was a significant difference in mean BCVA at 1 year among all 3 cohorts (P < .001), as well as between cohorts in pairwise comparisons, with the most significant gains in the monthly group. A total of 82.5% of the patients retained visual acuity of 20/200 or better, and 20.0% improved 10 or more ETDRS letters. CONCLUSIONS Ranibizumab may improve vision and anatomy in patients with radiation retinopathy-related macular edema and prevent vision loss through 48 weeks of therapy. Monthly injections were more effective than as-needed approach, and the addition of TRP yielded no therapeutic benefits.
