Bio-socio-demographic study of individuals with Pteryzium: A case series type of descriptive study
Abstract
Pterygium is a common disorder in many parts of the world including India. So this study is designed to find out the bio-socio-demographic profile of Pteryzium cases which can help in understanding its distribution. This study observed that mean age of individuals with Pteryzium was 37.23±1.71 years. Maximum number of cases belongs to ≥26-50 years of age (83%). Pterygium was found slightly more in females was 55.71% as compared to males (44.29%). Most of the cases were housewife (52.86%) followed by labourer (14.29%). Majority (80%) cases were exposed to sunlight. Mean size of pterygium was 2.616±0.529 mm ranging from 2 mm to 3.8mm.In our study, with Keratometer, mean astigmatism was found 1.35±1.127D and from Scheimpflug imaging, mean astigmatism was found 1.22±0.95D in this study.

Introduction
Sight is one of the best and most precious gift that God has bestowed upon us. Pterygium most often refers to a benign growth of the conjunctiva Pterygium is a common disorder in many parts of the world, with reported prevalence rates ranging from 0.3 to 29%.
Pterygium is commonly seen in India, a part of the "pterygium belt" described by Cameron1 . A “pterygium belt” has been mapped within the 30th parallels and is rare in north or south of the 40th parallels. Studies suggest an association with chronic exposure to UV- B radiations2,3
Several reports have previously demonstrated that pterygia cause corneal distortion and induce a significant amount of astigmatism. 4,5,6,7,8 Most of those topographic changes in the cornea have been reported to be reversed by successful pterygium surgery, although eyes with advanced pterygia might not normalize completely.14,8,9
Heat, dry atmosphere, high winds and abundance of dust have been implicated in etiopathogenesis.10 Pterygium occurs as a result of disruption of tear film either by rapid evaporation or by microtrauma from microparticles of dust.10
Conclusion
This study concludes that mean age of individuals with Pteryzium was 37.23±1.71 years. Maximum number of cases belongs to ≥26-50 years of age (83%). Pterygium was found slightly more in females was 55.71% as compared to males (44.29%). Most of the cases were housewife (52.86%) followed by labourer (14.29%). majority (80%) cases were exposed to sunlight. Mean size of pterygium was 2.616±0.529 mm ranging from 2 mm to 3.8mm. With Keratometer, maen astigmatism was 1.35±1.127D and from Scheimpflug imaging, mean astigmatism was 1.22±0.95D in this study.
