Histopathological study of pterygium

Abstract

Pterygium is a degenerative ocular disorder. The objective of this study was to determine the various histopathological changes in pterygium. Various findings such as goblet cell hyperplasia, basophilic degeneration, neovascularization, inflammatory infiltrate and dysplasia was observed. Ocular surface squamous neoplasia (OSSN) was identified in 14 out of 66 cases (21.3%). This high rate of OSSN in patients with pterygium is sufficient for the histopathological examination of all pterygium specimens so that patients can be warned of the possible recurrence of OSSN at a later time.
