Abstract

Purpose: : To assess the influence of pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) on retinal nerve fiber layer thickness (RNFLT) using optical coherence tomography (OCT).

Methods: : In 54 eyes of 54 patients undergoing primary PPV for RRD, RNFLT was assessed using OCT (Zeiss OCT3000). Contralateral healthy eyes of the patients served as the control group. Superior, inferior, nasal, temporal, and average RNFLT was analyzed. Multivariate analysis was performed to investigate the relationship between various explanatory factors and average RNFLT. Explanatory factors included age, best-corrected visual acuity (BCVA) after surgery, highest intraocular pressure after surgery, follow-up time, duration of RRD, location and area of RRD, and circumferential dimension of retinal tears.

Results: : Mean follow-up time was 3-60 months. Average RNFLT of the RRD eyes was significantly thinner than that of the control eyes (p<0.005), and superior RNFLT was significantly thinner than that of the control eyes (p<0.0001). None of the explanatory factors was found to be significantly associated with average RNFLT.

Conclusions: : Average RNFLT and superior RNFLT were thinner after PPV for RRD than the control eyes.
