ABSTRACT Background & Objectives Pterygium being a prevalent ocular surface lesion, alteration in normal functioning of tear film is noticed leading to various ophthalmic features which may be mild to vision threatening, thus, it should be investigated thoroughly to prevent, treat or limit complications. Material & Methods This study was conducted at NMCTH, Birgunj from August 2018 to July 2019 taking sample size of 93 cases of pterygium and 186 non-pterygium patients with no ocular surface disorder and objective analysis was done by Schirmer’s I without and with anaesthesia and Tear Breakup Time. Results During the study period of one year, out of 93 patients in Pterygium group, 48 (51.6%) were male and 45 (48.4%) were female, Age of patients ranged from 26 - 71 years and the mean age was 47.8 years (SD ±11.09). In age matched other non-pterygium group without ocular surface disorder 186 in number, 101 (54.3%) were male and 85 (45.7%) were female and average age was 42.16 (SD ±13.13). On analyzing the objective tear film stability indices for both groups, I obtained mean SCH I without and with anesthesia and TBUT values as, 16.94 mm, 13.81 mm, 10.14 sec in pterygium cases respectively with their SD of ±5.61, ±5.06 and ± 4.06 respectively while indices of non-pterygium group were 20.39 mm, 16.74 mm, and 13.05 sec and SD was ±6.08, ±5.25 and ±4.32 respectively. The statistical difference of dry eye indices between the pterygia group and the non pterygia group were significant with p-value < 0.001. Conclusion There is statistically significant difference in dry eye results between pterygium patients and patients without pterygium, thus our study concludes with results that pterygium being an ocular surface disorder leads to instability of tear film and thus dry eye.
