Aim: To study the effect of retinal laser photocoagulation on contrast sensitivity in diabetic retinopathy.
Method: Prospective interventional study of all the patients with diabetic retinopathy presenting at our Institute of Ophthalmology with indications of Retinal Photocoagulation. Contrast sensitivity was assessed prior to laser and then again after 1 week of 1st and 2nd sitting and after 6 weeks of 3rd sitting of panretinal photocoagulation. The Contrast Sensitivity was statistically compared and he data collected was analyzed for statistical significance using SPSS version 20 by Repeated ANOVA test.
Result: The contrast sensitivity improved in 24 eyes (68%), decreased in 2 eyes (6%) while it remained constant in 9 eyes (26%).
Conclusion: Retinal Laser Photocoagulation causes statistically significant improvement in contrast sensitivity after a period of 6 weeks post laser in patients of diabetic retinopathy.
