Ocular Surface Squamous Neoplasia (OSSN) includes the entire spectrum of dysplastic, pre-invasive and malignant squamous lesions of conjunctiva and cornea, typically presenting as slightly elevated pearly grey growth straddling the limbus with tufts of feeder vessels. Etiological factors are UV-B light, HPV-16, HIV seropositivity and stem cell factors.
Interferon α 2b (INF- α 2b) has been used as off-label immunotherapy in OSSN. It is a naturally occurring glycoprotein which binds to cell surface receptors affecting intracellular events resulting in antitumor and antiviral properties.
