Aniseikonia after reduced-fluence photodynamic therapy in patients with central serous chorioretinopathy.

This study investigated aniseikonia after reduced-fluence photodynamic therapy (RFPDT) for central serous chorioretinopathy (CSC). We examined 48 eyes of 48 patients (38 men; mean age, 49.2 ± 9.9 years) with CSC resolved after RFPDT. Horizontal and vertical aniseikonia were measured using the New Aniseikonia Test at baseline, 6 months, and 12 months after RFPDT. The maximum absolute value of the horizontal and vertical measurements indicated the aniseikonia score. The aniseikonia score was 2.2 ± 2.3 at 6 months and 2.2 ± 2.0 at 12 months after RFPDT, both of which improved significantly from the baseline score of 4.1 ± 2.9 (P < 0.05 and P < 0.01, respectively). The 12-month aniseikonia score significantly correlated with the baseline aniseikonia score (P = 0.047), outer nuclear thickness at baseline (P = 0.027) and 12 months after RFPDT (P = 0.014), baseline SRD area (P = 0.005), and ellipsoid zone disruption at 12 months after RFPDT (P = 0.021). In multivariate analysis, baseline serous retinal detachment (SRD) area (P = 0.034) was significantly associated with aniseikonia score at 12 months after RFPDT. Eyes with a larger SRD area might have higher aniseikonia scores even after SRD resolution following RFPDT.

Short-Term Outcomes of Faricimab Treatment in Aflibercept-Refractory Eyes with Neovascular Age-Related Macular Degeneration.

To evaluate the functional and anatomical effects of switching to faricimab for patients with neovascular age-related macular degeneration (nAMD) refractory to intravitreal aflibercept, this retrospective study evaluated patients with nAMD who received intravitreal injections of aflibercept (IVA) every <8 weeks and were switched to faricimab. After switching, the patients were treated with a treatment and extended regimen that started with the interval just before switching and received at least three injections. We evaluated changes in the best-corrected visual acuity (BCVA), central retinal thickness (CRT), central choroidal thickness (CCT), treatment interval, and presence of retinal fluid. Overall, 55 eyes from 55 patients were examined. After three injections of faricimab, the BCVA and CCT did not change significantly. However, the CRT decreased significantly (p < 0.05), the injection interval was significantly extended (7.5 ± 2.3 vs. 5.9 ± 1.5 weeks, p < 0.01), and the rates of the presence of intraretinal fluid and subretinal fluid decreased significantly to 16.4% and 40% of eyes, respectively (both p < 0.01). An ocular adverse event (retinal pigment epithelium tear) developed in one eye. Switching to faricimab was effective for anatomic changes. It may be an additional treatment option for some eyes refractory to IVA.

Two-year outcome of half-time photodynamic therapy for chronic central serous chorioretinopathy with and without choroidal neovascularization.

PURPOSE: To compare the two-year outcome of half-time photodynamic therapy (htPDT) in chronic central serous chorioretinopathy (cCSC) with and without choroidal neovascularization (CNV). METHODS: In this retrospective study, we included 88 eyes of 88 patients with cCSC who underwent htPDT and were followed up for more than 24 months. Patients were divided into two groups with (21 eyes) or without (67 eyes) CNV before htPDT treatment. The best-corrected visual acuity (BCVA), central retinal thickness (CRT), subfoveal choroidal thickness (SCT), and the presence of subretinal fluid (SRF) were evaluated at baseline and at 1, 3, 6, 12, and 24 months after PDT. RESULTS: A significant intergroup difference was noted in terms of age (P = 0.038). Significant improvements in the BCVA and SCT were found at all time points in eyes without CNV but only at 24 months in eyes with CNV. CRT was significantly reduced in both groups at all time points. No significant intergroup differences were noted in terms of BCVA, SCT and CRT at all time points. There were significant differences in the rate of recurrent and persistent SRF between groups (22.4% (without CNV) vs. 52.4% (with CNV), P = 0.013, and 26.9% (without CNV) vs. 57.1% (with CNV), P = 0.017, respectively). The presence of CNV was significantly associated with the recurrence and persistence of SRF after initial PDT (P = 0.007 and 0.028, respectively). Logistic regression analyses showed that the baseline BCVA, and not the presence of CNV, was significantly associated with BCVA at 24 months after initial PDT (P < 0.01). CONCLUSIONS: A htPDT for cCSC was less effective in eyes with CNV than in those without CNV regarding the recurrence and persistence of SRF. Additional treatment might be required in eyes with CNV during 24-month follow-up periods.
