Topical interferon alpha-2B topic as the first therapeutic option in a clinical case of conjunctival intraepithelial neoplasia.

INTRODUCTION

Conjunctival intraepithelial neoplasia is a pre-malignant lesion of the ocular surface. It can be treated with topical interferon alpha-2b (INF α-2b) as first choice.

CLINICAL CASE: A 71-year-old man referred for corneal-conjunctival, gelatinous lesion in the left eye (LE) with an area of almost 270°. The clinical diagnosis was compatible with a corneal-conjunctival intraepithelial neoplasia. Topical treatment was started with INF α-2b at a dose of one million international units (IU)/ml, 4 times/day for 4 months, with remission being achieved.

CONCLUSION

The isolated use of topical INF α-2b is an effective treatment as a first option in the case of corneal-conjunctival intraepithelial neoplasia, positioning itself as a form of effective and safe treatment compared to other therapeutic options. Surgical excision and use of other chemotherapy agents could lead to severe limbic deficits and other side effects.
