Prevalence of Pterygium and Visual Impairment in Patients at a Tertiary Care Centre of Etawah District: A Hospital Based Study
Abstract:
Introduction: Pterygium is a non-malignant, slow
growing, wing shaped proliferation of the fibro vascular tissue, which is arising
from the sub-Conjunctival tissue, which may extend over the cornea and thus disturbing
the vision.
Background
and Purpose: To assess the prevalence
of Pterygium and Visual impairment in patients at a tertiary care centre of Etawah
district.
Methods:
A cross-sectional study was done over a period of 3 months
on both genders with the categorised age group and into grades according to the
size of the Pterygium in the Department of Ophthalmology at UP University of Medical Sciences hospital Saifai,
Etawah. After taking an informed consent a total
of 2100 patient were examined by eye screening and diagnosed with the help of ophthalmologist
in which 130 patients were found with Pterygium problem. Out of these 94
patients (135 eyes) was found purely with Pterygium in one or both eyes and the
rest 36 were excluded because of other associated morbidities. The selected participants underwent assessment
by eye examination sheet and the subject undergone specific test. The data were
recorded on the basis of set predesigned, pretested, semi structured questionnaires
and the grading was done with the help of slit lamp examination.
The data was collected and analyzed using chi square test.
Result and conclusion: A high prevalence of Pterygium was found in patients working in outdoor (76.29%) in comparison to indoor (23.70%) because of exposure to sunlight.
