Navigated focal laser photocoagulation of choroidal neovascularization in central serous chorioretinopathy

Purpose. To study the efficacy and safety of focal navigated laser photocoagulation (FLC) in the treatment of central serous chorioretinopathy (CSCR) complicated by choroidal neovascularization (CNV). Material and methods. The study included patients with CSCR complicated by CNV, defined as the presence of characteristic OCT angiography features. All patients underwent FLP, in the area of CNV localization, using the NAVILAS 577 navigation laser system, followed by at least six months of followup. The main outcome measure was complete resolution of subretinal fluid (SRF) at the end of follow-up. Results.This study included 16 eyes of 16 patients (6 males and 10 females, mean age 59.3 ± 7.9 years). Mean baseline CNV area was 0.44 ± 0.23 mm2. All eyes achieved complete resolution of SRF at 1.1 ± 0.4 months after FLP. At the beginning and at the end of follow-up best-corrected visual acuity was 0.16 ± 0.17 and 0.07 ± 0.12 LogMAR (p = 0.12), respectively. Central retinal thickness decreased from 372.4 ± 83.06 to 215.3 ± 21.5 μm (p < 0.0001), while subfoveal choroidal thickness remained stable (344.6 ± 101.0 μm at baseline and 316.8 ± 99.9 μm at the end of the follow-up; p = 0.53). No visual or anatomical deterioration was observed during 11.5 ± 7.5 months of follow-up. Conclusion.Navigated FLP of the area of CNV is an effective and safe option in the management of CSCR complicated by relatively small extrafoveal neovascular membranes.
