Interferón alfa-2B tópico como primera opción terapéutica en un caso clínico de neoplasia intraepitelial córneo-conjuntival / Topical interferon alpha-2B topic as the first therapeutic option in a clinical case of conjunctival intraepithelial neoplasia

Introducción: La neoplasia intraepitelial córneo-conjuntival es una lesión premaligna de la superficie ocular. Puede ser tratada con interferón alfa-2b (INF α-2b) tópico como tratamiento de primera elección. Caso clínico: Varón de 71 años de edad remitido por lesión córneo-conjuntival en ojo izquierdo (OI) de aspecto gelatinoso con una extensión de casi 270° (de las IX a las V h), cuyo diagnóstico clínico era compatible con una neoplasia intraepitelial córneo-conjuntival. Se inició tratamiento tópico con INF α-2b, en dosis de un millón de unidades internacionales (UI)/mililitro (ml), con una posología de 4 veces/día durante 4 meses, con lo que se consiguió su remisión. Conclusión: El uso aislado de INF α-2b tópico es un tratamiento efectivo como primera opción en el caso de neoplasia intraepitelial córneo-conjuntival, que se sitúa como una forma de tratamiento eficaz y segura frente a otras opciones terapéuticas como la escisión quirúrgica y frente al empleo de otros agentes quimioterápicos que pueden condicionar insuficiencias límbicas severas, entre otros efectos secundarios (AU)

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 (AU)
