An analytical study on the epidemiology ofpterygium in a tertiary care centre
Journal Title: Medpulse International Journal of Ophthalmology - Year 2019, Vol 10, Issue 2
Abstract
Aim: To study and analyse the epidemiology ofpterygiumin a tertiary care centre. Design: Cross sectional observational study. Materials and methods: The patients more than 20 years of age, with true pterygium attending the outpatient clinic of Department of Ophthalmology of Coimbatore Medical College Hospital were included in the study. Data collection was done using a structured questionnaire which comprises of socio-demographic characteristics including age, sex, occupation and detailed history.The exact hours of sun exposure per day and the years of sun exposure werenoted as well as any other ocular or systemic co morbid conditions like diabetes and hypertension. A complete ocular examination was done and recording of the uncorrected and best corrected visual acuity along with the degree of astigmatism was done with the help of automated keratometry. Tear film was assessed with Schirmer’s test and tear film break-up time. Results and conclusion: Middle aged to elderly people were found to bemore affected due to their prolonged exposure to inciting agents in the environment. There was no significant gender predilection, if the environmental factors are the same. Sunlight exposure was found to be a significant risk factor and dry eye played a contributory role. No co relation was found between development of pterygium and systemic diseaseslike diabetes and hypertension.
