PEREZ DE ARCELUS, M.; ARANGUREN, M.  e  ANDONEGUI, J.. Topical interferon alfa-2b for primary treatment of conjunctiva-cornea intraepithelial neoplasia. Anales Sis San Navarra [online]. 2012, vol.35, n.1, pp.137-141. ISSN 1137-6627.

We describe two cases of conjunctival-cornea intraepithelial neoplasia (CIN), treated with topical IFN alfa 2b. The traditional treatment for CIN is surgical excision usually with adjunctive cryotherapy. However, residual tumour may remain, which can lead to recurrence rates of more than 50%. 5-Fluorouracil, mitomicyn C and interferon alfa 2b are new pharmacological agents that have proved their efficacy in the treatment of CIN. As side effects are common, we present IFN alfa 2b as a single therapeutic agent as an effective and optimal treatment for presumed recurrent corneal and conjunctival intraepithelial neoplasia. It offers the benefits of topical therapy and avoids the risks of surgical or other interventions - specifically, ocular surface toxicity, cicatricial conjunctival changes, and limbal stem cell deficiency.
