A Hospital-based Clinical Study on Risk Factors of Pterygium
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 9
Abstract
Background: Pterygium is a common ophthalmological disease seen in day-to-day practice. Many factors play their role individually and collectively in causing pterygium. The present study analyses the different risk factors in patients attending a tertiary teaching hospital. Aim of the Study: This study aims to determine the risk factors associated with pterygium through history taking and examination findings. Materials and Methods: A total of 46 patients with pterygium were included in the study excluding other systemic and local diseases producing dry eye. Thorough clinical and ophthalmology examination was done to know the risk factors contributing to pterygium. The breadth and pterygium on long axis was measured. Observation and Results: Among the 46 patients, there were 35 (76.08%) males and 11 (23.91%) females with a male-to-female ratio of 3.18:1. The age of the patients was from 23 to 67 years with a mean age of 49.63 ± 3.72. Exposure to dust, hot, and dry atmosphere was in 34 (73.91%) patients. Exposure to toxic fumes and other irritating substances was observed in 29 (63.04%). 30 (65.21%) patients were working in outdoors when compared to 16 (34.78%) patients in indoors in this study. Xerophthalmia was reported by 22 (47.82%) of the patients in this study. Conclusions: Even though the risk factors of pterygium identified in the study are outdoor exposure to ultraviolet light, toxic fumes, dust, and dry hot weather conditions. The examination findings point toward the presence of multiple associations simultaneously in most of the patients, and this overlap of associations indicates several factors operating together to cause pterygium and not a single factor.
