Abstract

Aim: To evaluate optical coherence tomography angiography (OCTA) in diabetic retinopathy (DR) after panretinal photocoagulation (PRP) Methods: In a prospective study on 52 eyes of DR, OCTA changes were examined at baseline and three months after PRP. Results: Distance BCVA reduced from LogMAR 0.700.18 to 0.760.18. The OCTA showed an enlarged, distorted and vertically oval foveal avascular zone (FAZ) and macular ischemia. The pre-treatment FAZ size, perimeter and circularity were 0.370.11 mm2, 2.571.35 mm and 0.390.11 and these increased to 0.380.19 mm2 (p=0.07), 2.621.32 (p=0.07) mm and 0.4140.17 (p=0.06) following PRP. The vascular density (VD) in superficial capillary plexus increased from 12.7911.11 to 23.2110.76 (p=0.02) and in deep capillary plexus increased from 7.257.09 to 10.15 7.38 (p=0.04) after PRP. Conclusion: The PRP in DR caused an increase in size of FAZ, perimeter, and circularity index. It also improved VD in SCP and DCP.
