Abstract To assess the correlation between structural changes using the optical coherence tomography and retinal function using microperimetry after successful retinal detachment surgery for primary rhegmatogenous retinal detachment. Prospective cross-sectional observational study Methods: 21 patients underwent surgery for rhegmatogneous retinal detachment (1 pneumatic retinopexy, 5 scleral buckling and 15 pars plana vitrectomy). OCT, microperimetry (using OPTOS OCT/SLO) and BCVA measurement were performed at 1 and 4 months post operatively. 17 patients were included in the statistical analysis to correlate OCT findings with BCVA and mean sensitivity at 1 and 4 months post-operative. Pre-operative data (age, duration of RD, no. of quadrants detached, height of RD, grade of PVR) were documented and included in the statistical analysis to detect if there are any pre-op predictive factors for the final BCVA and mean sensitivity post-operative. The mean postoperative final BCVA was 0.75 +/- 0.24 LogMAR and mean macular sensitivity was 9.41 +/- 3.38 decibels. OCT showed micro structural changes. The most frequent changes were IS/OS disruption and ELM disruption (70.6%). Statistical significant difference was found for the decrease in BCVA and mean sensitivity in the presence of IS/OS disruption (p=0.04, p=0.035 respectively), and ELM disruption (p=0.014, p=0.006 respectively). Age, duration of retinal detachment and pre-operative vision are strong prognostic factor for the final BCVA and mean sensitivity |
