A Successfully Treated Case of Invasive Ocular Surface Squamous Neoplasia Involving the Subtotal Cornea in a Monocular Patient: Management in a Resource-Constrained Setting

We present a case of a 65-year-old monocular patient who was clinically diagnosed with ocular surface squamous neoplasia covering all but 2 clock hours of the limbus and almost the entire cornea. He underwent complete tumor excision followed by amniotic membrane transplantation. Postexcision, the patient had a clear cornea and stable ocular surface without inflammation or recurrence for 18 months of follow-up. The visual acuity improved to 6/18 from count fingers at face. The histopathology result uncovered squamous cell carcinoma of conjunctiva and cornea. The absence of recurrence can be attributed to complete excision and intraoperative mitomycin C.
