Abstract

The authors describe two cases of corneal ocular surface squamous neoplasia (OSSN), presenting at our rural eyecare centre, which were initially misdiagnosed as viral epithelial keratitis and corneal pannus with focal limbal stem cell deficiency. Both the cases were refractory to initial treatment and corneal OSSN was suspected. Anterior segment-optical coherence tomography (AS-OCT) revealed a thickened, hyper-reflective epithelium with abrupt transition and an underlying cleavage plane, features typical of OSSN. Topical 1% 5-fluorouracil (5-FU) therapy was initiated and in two cycles (first case) to three cycles (second case), complete resolution was noted both clinically and on AS-OCT, with no significant side effects. Both patients are currently free of tumour at the 2-month follow-up period. The authors report the rare, atypical presentations of corneal OSSN, discuss the masquerades and highlight the role of primary topical 5-FU in managing corneal OSSN in limited resource settings.
