Does choroidal thickness predict persistent subretinal fluid after rhegmatogenous retinal detachment repair? A retrospective study with fellow eye comparison

Abstract

Purpose To evaluate whether choroidal thickness (CT) is associated with persistent subretinal fluid (pSRF) after simple primary rhegmatogenous retinal detachment (RRD) repair. Methods This single‐centre, retrospective, observational study included patients who underwent RRD repair with at least 12‐month follow‐up. Preoperative and postoperative parameters were evaluated for association with pSRF. CT measurements were obtained at the central 1 mm area on enhanced depth imaging (EDI) OCT scans, using a semiautomatic method. Multiple logistic regression analyses were assessed to determine predictive factors for pSRF. Results Overall, 100 eyes of 100 patients, mean age of 59.9 ± 12.6 years were included. pSRF was found in 21.0% of eyes and resolved over time in 85.7% of eyes at 12 months. In the pSRF group both RRD and fellow eyes showed lower mean choroidal and RPE thickness values as compared to those without pSRF (p < 0.05). A significant correlation was found between pSRF occurrence and choroidal thinning (p = 0.02). After multiple regression analyses, macula‐off RRD (p = 0.005) and scleral buckling (SB) technique (p = 0.001) were retained as final predictors for pSRF. In macula‐off SB eyes, detachment duration was the only factor associated with pSRF (p = 0.046). There were no significant differences in best‐corrected visual acuity outcomes between the pSRF and the no‐pSRF eyes. Conclusions Patients with pSRF showed lower choroidal and RPE thickness as compared to those without pSRF. CT did not turn out to be a final predictor for pSRF, as this was mainly associated with macular involvement, surgical technique and detachment duration.

“…Peripapillary Retinal Nerve Fiber Layer (pRNFL) thicknesses were acquired using a 12 • circular scan centered on the optic disk with 100 frames, and 360 • peripapillary RNFL, as well as superior, temporal, inferior, and nasal quadrant average thicknesses, were recorded. Choroidal thickness (CT) measurements at the central 1 mm area of the ETDRS macular grid were obtained from the horizontal, raster, 20 • × 20 • , 19-line enhanced depth imaging (EDI) scan protocol using a semiautomatic method [29].…”
