Abstract
The aim of our study is to correlate the structure-function relationship of the macula following successful repair of rhegmatogenous retinal detachment, by correlating the SD OCT and FAF macular images with BCVA. Prospective observational case series study. Forty five eyes underwent surgical repair of RRD followed by SD OCT and FAF imaging one to three months post operative. SD OCT and FAF findings were correlated with post - operative BCVA. Forty - five eyes achieved complete post-operative reattachment with 95.6% SOSR. Mean preoperative logMAR visual acuity showed significant difference with mean postoperative logMAR BCVA (p < 0.001). Statistical analysis showed significant correlation between the duration of retinal detachment and log MAR BCVA (r = 0.503, p < 0.001). The values of BCVA showed significant difference between eyes with the following OCT findings: macular edema, persistent SRF, RPE choriocapillaries complex, IS/OS junction disruption and neurosensory detachment and eyes not showing the same OCT changes (p < 0.05). The values of BCVA showed significant difference between eyes showing hyper-autofluorescence on FAF imaging and eyes not showing hyper-autofluorescence (p = 0.015). We found significant association between fundus hyper-autofluorescence and the following OCT findings: macular edema, RPE-choriocapillaries complex irregularity, IS/OS junction disruption and neurosensory detachment
