Abstract
Purpose
To evaluate the efficacy of navigated focal laser photocoagulation in patients with chronic central serous chorioretinopathy (CSCR) and active leakage on fluorescein angiography (FA).
Methods
Thirty-two eyes of 32 patients (age 48 ± 11, m/f = 24/8) with persistent or recurrent CSCR (> 3 months) who received navigated laser photocoagulation (Navilas®) of leaking point(s) between June 2013 and 2016 were included in this retrospective case series. Outcome parameters after 4 weeks and 3 months were the number of patients presenting with complete resolution of subretinal fluid, the volume of subretinal fluid measured on SD-OCT (Spectralis Heidelberg Engineering©), and best corrected visual acuity (BCVA/ (Snellen equivalent).
Results
Complete resolution of subretinal fluid was achieved in 17 eyes (50%) after 4 weeks and in 24 eyes (75%) after 3 months with an average number of 1.3 laser procedures (range 1–3). Five eyes displayed a nearly complete resolution with a reduction of over 80% of the subretinal fluid compared to baseline. Three eyes showed no reduction in subretinal fluid. BCVA improved from median 0.58 (range 0.16–1.25) to 0.66 (0.16–1.0) (p = 0.001). The seven patients who had been treated within the central 1 mm of the ETDRS-OCT Grid but outside the avascular foveal zone showed an improvement of BCVA from median 0.6 (range 0.2–1.0) to 0.8 (0.2–1.0). No patient experienced a treatment-induced visual loss.
Conclusions
Laser treatment with Navilas® using eye tracking and FA-based planning is a safe and effective alternative therapy in patients with chronic CSCR.
