Figure 3: Slit-lamp photographs of a giant ocular surface squamous neoplasia with extensive limbal and corneal involvement. (a) Pretreatment and (b) posttreatment showing complete tumor regression after topical interferon alpha-2b (3 months) and 5-fluorouracil (2 weeks) after a follow-up of 17 months. Note the absence of pannus, corneal opacities, limbal stem cell deficiency, corneal or scleral thinning. (c) Slit-lamp photograph of ocular surface squamous neoplasia with predominantly corneal involvement. Pretreatment (c and d) after complete tumor resolution posttopical interferon alpha-2b (3 months) at 9 months follow-up. Note no evidence of corneal haze or opacity
