Purpose: To determine the effect of Panretinal photocoagulation on RNFL thickness , as determined by using OCT in diabetic retinopathy.
Material and method: This is a prospective observational study. 50 eyes of 30 patients of diabetic retinopathy who were planned for panretinal photocoagulation (PRP), were evaluated. Study was carried from January 2015 to December 2015. Baseline retinal nerve fibre layer thickness was measured using SD-OCT, and was repeated in these 50 eyes at 3 months and 6 months after PRP. Data was evaluated, compared and statistical analysis was performed.
Result and conclusion: The average RNFL shows significant thickening over 6 months post PRP .This change in peripapillary RNFL thickness varies according to RNFL quadrant. The superior and inferior quadrant RNFL thickness increased significantly in 6 months post PRP. The nasal and temporal quadrants RNFL thickness increased in 6 months post PRP, but did not show any significant change, at any follow up visits.
