Abstract: Objective: To the measure the effect of retinal laser on contrast sensitivity(CS), visual acuity and self reported visual disability in patients of diabetic retinopathy (DR). Methods: A prospective and analytical study in 53 eyes undergoing frequency doubled Nd-YAG retinal laser photocoagulation for DR was conducted over a period of 1 year at a tertiary care center. Best corrected visual acuity (BCVA) and CS were measured before each laser sitting and on subsequent follow-ups. The pre-laser measurements were compared with those of 3 month follow-up. On the final visit a self reported visual disability questionnaire was administered.
