Long term use of topical interpheron alpha 2-b for recurrent conjunctival squamous neoplasia

CASE STUDY: An 80-year-old woman diagnosed with a recurring conjunctival squamous cell carcinoma treated by surgical excision of the lesion, ocular surface reconstruction and topical interferon alpha 2-b. DISCUSSION: Squamous cell carcinoma is the most frequent malignant tumour of the ocular surface. Surgical removal of the lesion is the traditional treatment for these tumours, but this technique has a high recurrence rate. Immunotherapy is the current alternative for these carcinomas. Recent studies have proven the effectivity of interferon against epithelial neoplasms of the ocular surface. We could consider life-long treatments with topic interferon depending on the clinical characteristics of the patient, as its side effects are uncommon
