Purpose: The aim of this study was to evaluate the efficacy of topical interferon (IFN) therapy in pseudophakic cystoid macular edema (P-CME). Methods: This is a prospective, interventional case series of patients with P-CME. Patients presenting with P-CME were given the option of topical IFN therapy against conventional treatment with oral, topical, intravitreal, and periocular steroid therapy and antivascular growth factors. Patients who consented for the same were advised to use the IFN drops four times/day. Commercially available injection IFN alfa-2b was reconstituted to prepare the eye drops (1 MIU/ml). Optical coherence tomography (OCT) was done at the baseline and on each review visit until complete resolution of P-CME. Results: Eight eyes of eight patients diagnosed with P-CME were studied. Mean central macular thickness (CMT) on OCT at the presentation (n = 8) and at 4 weeks post topical IFN therapy (n = 6) was 560.1 μm (range: 349–702 μm) and 344.33 μm (range: 250–390 μm), respectively. All eyes except one had posterior capsular rent (PCR). Five patients had regular follow-up until resolution. The mean duration of complete first resolution of P-CME was 5 weeks (range: 4–7.1 weeks) in those patients. Relapse was seen in three patients who responded after resuming or continuing the therapy. Case 1 had 9 months follow-up after completion of IFN therapy, and no recurrence was noted. No ocular or systemic side effects related to the topical IFN therapy were noted clinically, except papillary conjunctivitis in one patient. Conclusion: Topical IFN therapy can be a noninvasive, economical, and effective choice of treatment for P-CME, especially in the case of PCR, and where steroids are contraindicated.

Purpose To evaluate the follow up and treatment outcome of central serous chorioretinopathy (CSCR) based on the new multimodal imaging-based classification and identify the predictors for anatomic and visual outcome. Methods Retrospective, multicentric study on 95 eyes diagnosed with CSCR and a follow up of at least 12 months were included. Eyes with macular neovascularization, atypical CSCR or any other disease were excluded. Results At the baseline, observation was advised to 70% eyes with simple CSCR whereas photodynamic therapy (PDT) was performed in 49% eyes with complex CSCR. Over the follow up, decrease in CMT was significantly higher in simple CSCR as compared to complex CSCR ( P = 0.008) and the recurrences were significantly more in eyes with lower CMT at baseline ( P = 0.0002). Median time of resolution of SRF was 3 months and 6 months in simple and complex CSCR respectively ( P = 0.09). For the 12 months follow up, the median fluid free period was greater ( P = 0.03) while number of interventions performed was lesser in eyes with simple CSCR as compared to complex CSCR ( P = 0.006). Multiple regression analysis showed baseline best corrected visual acuity (BCVA) and baseline persistent SRF to be significantly predictive of BCVA and persistent SRF at 12 months ( P < 0.0001, 0.04) respectively. Conclusions Complex CSCR more often required PDT, was associated with shorter fluid free interval and longer time for SRF resolution. Baseline BCVA and persistent SRF were predictive of final visual and anatomical outcome. The new multimodal imaging based classification is helpful in establishing objective criteria for planning treatment approaches for CSCR.

This study evaluated predictors for choroidal neovascularization (CNV) associated with central serous chorioretinopathy (CSCR) based on multimodal imaging. A retrospective multicenter chart review was conducted on 134 eyes of 132 consecutive patients with CSCR. Eyes were classified as per the multimodal imaging-based classification of CSCR at baseline into simple/complex CSCR and primary episode/recurrent/resolved CSCR. Baseline characteristics of CNV and predictors were evaluated with ANOVA. In 134 eyes with CSCR, 32.8% had CNV (n = 44) with 72.7% having complex CSCR (n = 32), 22.7% having simple (n = 10) and 4.5% having atypical (n = 2). Primary CSCR with CNV were older (58 vs. 47, p = 0.00003), with worse visual acuity (0.56 vs. 0.75, p = 0.01) and of longer duration (median 7 vs. 1, p = 0.0002) than those without CNV. Similarly, recurrent CSCR with CNV were older (61 vs. 52, p = 0.004) than those without CNV. Patients with complex CSCR were 2.72 times more likely to have CNV than patients with simple CSCR. In conclusion, CNV associated with CSCR was more likely in complex CSCR and older age of presentation. Both primary and recurrent CSCR are implicated in CNV development. Patients with complex CSCR were 2.72 times more likely to have CNV than patients with simple CSCR. Multimodal imaging-based classification of CSCR supports detailed analysis of associated CNV.

Objective The objective of this study was to assess the structural-functional relationship in choroideremia (CHM) patients using optical coherence tomography (OCT) and autofluorescence (AF) images. Methods In this study, 53 eyes of 28 CHM patients were included. Demographic, ocular and clinical fundus features were recorded. Fundus AF and OCT images were analysed. Patients were classified into two groups based on AF features: group 1, CHM patients where the foveal island was present and group 2, CHM patients where the foveal island was absent. Inner and outer retinal layer thicknesses, retinal pigment epithelium (RPE) and subfoveal choroidal thickness (SFCT) were measured and correlated with visual acuity (VA). Results There were 26 eyes in group 1 and 27 eyes in group 2. Mean age in groups 1 and 2 were 51.7 ± 13.4 and 63.6 ± 11.6 years, respectively. Age (p = 0.001) and VA (p < 0.001) between the two groups were significantly different. The retinal and SFCT showed significant differences that were analysed for each eye between the two groups. Reduced VA was noted with increasing age (r = 0.483; p ≤ 0.001), thin total retina (r = −0.378; p = 0.005), inner (r = −0.512; p < 0.001), outer (r = −0.59; p < 0.001) retinal thicknesses and thin RPE (r = −0.653; p < 0.001). Multivariate analysis showed RPE thickness (p = 0.001) as the most important index that affected VA. Conclusion RPE thinning contributes to poor VA in patients with advanced CHM. Further studies are needed to evaluate the role of retinal thickness and SFCT and its relationship to VA.
