To evaluate foveal morphologic changes in eyes with anatomically successful repair of rhegmatogenous retinal detachments (RRD)
DESIGN: Retrospective, consecutive, observational case series.
From June 2010 to January 2014, we observed 112 eyes from 108 patients who underwent 25-gauge pars plana vitrectomy as the primary surgery for RRDs. The average follow-up duration was 7.8 ± 2.8 months (range, 6–15 months). A microscopic fundus examination was conducted followed by Time-domain and Spectral-domain optical coherence tomography (TD-OCT and SD-OCT) to assess the postoperative foveal microstructure at one month, three months and six months. The correlation between the postoperative best-corrected visual acuity (BCVA) and microstructural findings at the fovea was evaluated.
Foveal anatomic abnormalities were detected in 67 eyes (60%); disruption of the junction between the photoreceptor inner and outer segments (IS/OS) in 52 eyes (46%), epiretinal membranes (ERM) in 22 eyes (20%), cystoid macular edema in 10 eyes (9%), and macular hole in 1 eye (%1). Disruption of the photoreceptor IS/OS junction was observed only in macula-off eyes. In preoperative macula-off eyes, the postoperative BCVA was significantly correlated with the integrity of the photoreceptor IS/OS signals detected by TD-OCT and SD-OCT postoperatively (P:0.001). Eyes with an ERM more often had multiple breaks (P:0.01).
After anatomically successful RRD repair, OCT is a valuable, noninvasive tool for evaluating foveal microstructural changes. The most common foveal morphologic changes are disruption of IS/OS and ERM.
