Abstract : Aim: To compare the tear film changes in diabetic population with and without diabetic retinopathy. To study the association of dry eye with different gradings of diabetic retinopathy. Materials and Methods: A case control study was conducted in 112 eyes in diabetics with and without diabetic retinopathy changes. Tests for tear film changes like Schirmers, TBUT and KES was conducted and the results were compared. Results: The mean value of Schirmer in diabetic retinopathy group was 10.84 +/- 4.785, mean value of TBUT was 7.73+/- 2.908 and that of KES was 1.34 +/- 0.745 whereas mean value of Schirmers in non DR group was 12.84+/- 2.947, that of TBUT was 10.43+/- 2.035 and that of KES was 0.73+/- 0.726. Significantly poorer Schirmers (p= 0.009), TBUT (p=0.001) and KES(p=0.001) was found in the DR group. Conclusion: With increasing severity of diabetic retinopathy these signs and symptoms of dry eye have found to increase thereby a significant association between dry eye and grading of DR.
