Ocular surface squamous neoplasia

Background: It describes a spectrum of conjunctival and corneal epithelial neoplasia, manifesting as Dysplasia, Carcinoma in Situ and Ocular squamous cell neoplasia (OSSN). Aim: To study the association between human immunodeficiency virus and ocular surface squamous neoplasia. Materials and methods: It was a prospective interventional study on total 60 eyes of 60 patients with Ocular squamous cell neoplasia (OSSN) was included in this study diagnosed Histopathologically. Bilateral and recurrent OSSN cases, which were diagnosed by repeat excision biopsy and HPE were included only once to exclude HIV statistics. Results: A total of 72 patients of clinical OSSN attended, the OP Department of Occuloplastics. 3 patients did not consent for surgery and were dropped from the study (2 HIV reactive 1 HIV non-reactive). 9 patients HPE negative for OSSN and were dropped from the study. 60 eyes of 60 patients were included in the study all had histopathologically confirmed diagnosis of OSSN. Minimum age was 6 years and maximum age was 80 years. HIV reactive and HPE positive OSSN was 12. 1 patient had lower lid palpabral conjunctival tumor OSSN – A typical presentation. CD4+ T lymphocytes of the patients were around 250 cells / cuml and below in all HIV positive patients. OSSN can occur from 6 years to 80 years Common age group for affection was 51 - 60 years i.e. above 50 years but it can affect any age group. This disease has male preference. HIV association was 20% of cases. Neglected old patients reported late i.e. 3.3% had radical surgery. Recurrence of the tumour was 3.3% so regular follow up is needed. OSSN develops when the CD4 counts were less than 250cell/cu ml. Conclusion: It can be concluded from the study that there is an association between HIV infection and OSSN.
