In the second case, an 81-year-old man, a nodular lesion in the temporal conjunctiva on his RE, with corneal adjacent opalescence, one millimeter in extent, was observed. Both patients were initially treated with excisional surgery, the samples being reported as conjunctival intraepithelial neoplasia with high-grade dysplasia. Co-adjuvant treatment with topical interferon alpha-2b 1\u2005mIU\/mL was indicated 4 times\/day uninterruptedly. In the first case, there was no response despite 8 months of treatment, while in the second, the corneal lesion progressed in an arboriform pattern after 4 months of topical chemotherapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Management &amp; outcome<\/jats:title>\n                    <jats:p>In the absence of efficacy, the treatment was then changed to topical 5-fluorouracil (1%), 4 times\/day for 7 days with a time-lapse of 21 days off, which constitutes a course. Two and four courses of treatment with 5-fluorouracil 1% were completed in both cases in the absence of important side effects. After the first course, both patients showed complete remission of the lesions. No clinical signs of relapse were noted after 1 year of follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n
