DRY EYE IN PATIENTS WITH PTERYGIUM- A CROSS-SECTIONAL STUDY AT A TERTIARY CARE CENTRE IN THRISSUR
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 6
Abstract
BACKGROUND Pterygium is a degenerative condition of the eye, recorded since ancient times.1 It is seen as a triangular patch on the exposed part of the eye. The main disadvantage due to the disease is cosmetic. It also causes vision defect due to either refractive error or extending over the visual axis. Aims and Objectives of the study are1. To find out proportion of dry eye among patients with Pterygium. 2. To find out the factors associated with dry eye among patients with Pterygium. MATERIALS AND METHODS A cross-sectional study was done on patients with clinical diagnosis of Pterygium. Information was collected on age, sex, occupation, dietary habit, smoking, menstrual history and systemic illness. Ocular examination including refraction with special emphasis on Schirmer’s test, Tear film Break-up Time, Tear Meniscus Height and Size of Pterygium was conducted. Data was entered into Microsoft Excel. Statistical analysis was made using Chi-Square test and Correlation. RESULTS Dry eye condition was assessed on the basis of the tests. 20.32% of eyes on Schirmer’s test, 35.77% of eyes on TBUT and 62.60% of eyes on TMH were found to have dry eye. Mean value of Schirmer’s test was 16.70 mm on right eye and 18 mm on left eye. Mean value of TBUT was 10.2 sec on right eye and 10.7 sec on left eye. Mean value of TMH was 0.4 mm in both eyes. The Dry eye tests of right and left eyes did not show significant difference in the case of unilateral Pterygium. The association between Dry eye tests and presence of Pterygium also did not show any statistically significant association, except in the case of TBUT and Pterygium on right eye. Association between dry eye tests and risk factors was positive only in the case of aged. The Dry eye tests between right and left eyes showed strong correlation, irrespective of unilateral or bilateral Pterygium. CONCLUSION Dry eye condition is seen in at least 20.32% of eyes, but significant association between Dry eye and presence of Pterygium is not seen. Age showed positive association with Schirmer’s test among the Pterygium patients. Also refractive error showed positive association with TBUT among the Pterygium patients.
