Congenital cysts of the iris stroma.

We studed the clinical and histopathologic findings in two congenital iris cysts, one in a 19-month-old girl and one in a 7-year-old boy. Our second case showed the resilience of these lesions, with the cyst returning to its original size after needle aspiration, argon iridotomy, marsupialization, and excisional iridotomy. Cryogenic therapy was needed to eliminate the cyst. In both cases, histologic studies showed squamous epithelium with few (Case 1) or no (Case 2) goblet cells.
