Abstract

The purpose of this study was to evaluate the incidence, clinical features, risk factors, and treatment outcomes in cases of Pigmented ocular surface squamous neoplasia (OSSN). This was a retrospective case-control study from a cohort of 223 cases with OSSN. All the tumor details including tumor epicenter, extent, tissues involved, tumor morphological pattern were recorded both pre and post treatment. Extent of pigmentation of OSSN determines the response to treatment. Interferon alfa 2b is an effective immunotherapy agent for tumors with ≤6 clock hours of ocular surface in 75% cases and serves as an immunoreducing agent for larger tumors involving >6 clock hours of ocular surface in 25% cases.
