Optical coherence tomography can be used in evaluation of morphological and functional results after successful rhegmatogenous retinal detachment surgery with different tamponade agents

Abstract

Background: Optical coherence tomography (OCT) findings are helpful in assessing the cause of reduced visual acuity (VA) after successful rhegmatogenous retinal detachment (RRD) surgery. Objective: To study anatomical and functional results after successful RRD surgery with gas-air mixture or silicone oil (SO) tamponade using OCT. Materials and methods. 70 patients were divided into 2 groups: group I (n = 34) - gas-air mixture tamponade; group II (n = 36) - SO tamponade. At baseline, were no significant differences by gender, age and VA between the groups. Follow-up was 12 months after the surgery. OCT was performed with the Cirrus HD-OCT 4000, CARL ZEISS MEDITEC, USA. Results: VA increased significantly in both groups. Regression analysis showed lower VA in group II and statistically significant association between VA and IS/OS and ELM defects. Сonclusions. There is a strong association of disruption of the IS/OS and ELM with reduced vision after successful retinal detachment surgery. Gas-air mixture tamponade showed some benefits in comparison with SO tamponade.
