Aim: To find out the proportion of Dry eye among patients affected with Pterygium. Materials And Methods: It was a cross-sectional study. The patients with clinical diagnosis of Pterygium were selected. Ocular examination with special emphasis on Schirmer test, Tear film Break–up Time, Tear Meniscus Height, size of Pterygium was conducted. Data was entered into Microsoft Excel. Statistical analysis was made using Chi-Square test and Correlation test. Results: Dry eye condition was assessed on the basis of the tests. 20.5% of eye on Schirmer test, 33.5% of eyes on Tear film Break–up Time, and 59.5% of eyes on Tear Meniscus Height were found to be affected with Dry eye. Mean value of Schirmer test was 16.94 mm on right eye and 17.85 mm on left eye. Mean value of Tear film Break–up Time was 10.14 sec on right eye and 10.72 sec on left eye.Mean value of Tear Meniscus Height was 0.39 mm on right eye and 0.38 mm on left eye. The association between Dry eye tests and presence of Pterygium not showed any positive association, expect in the case of Tear film Break–up Time and Pterygium on right eye. The Dry eye tests between right and left eyes showed strong association, irrespective of unilateral or bilateral Pterygium. Conclusion: Dry eye condition is seen at least in 26% of eyes, but significant association between Dry eye and presence of Pterygium is not seen. Irrespective of the eye affected with Pterygium, Dry eye tests of both eyes showed strong association. Further case control studies can be done.
