Study of surgical outcome of sutureless & glueless conjunctival autografting after pterygium surgery: a retrospective study
Journal Title: IP International Journal of Ocular Oncology and Oculoplasty - Year 2016, Vol 2, Issue 3
Abstract
The term pterygium comes from the ancient Greek word (pteryx: wing & geon: fin). Pterygium is characterized by a triangular portion of bulbar conjunctiva encroaching upon the cornea(1) . Pterygium is most common in the so called “Pterygium area” which is defined by geographical altitude of 40 degree north and south of equator(1) . It is more common in adult male involving in outdoor activities(2) . The exact cause of pterygium is still unknown but UV radiation is supposed to be the most important cause. Other causes include exposure to dry & dusty environment. Pterygium is most often seen from nasal side in the inter-palpebral area. The nasal affinity of pterygium is attributed to the fact that a greater portion of bulbar conjunctiva is exposed to the UV radiation. Secondly there is sparseness of subconjunctival tissue in the temporal region & the temporal region is exposed to a lesser extent to UV radiation due to a greater amount of bowing of outer 2/3rd of upper lids.
