secondary epitheial iris cyst with pus-like precipitate: a rare presentation

purpose: to report two cases of secondary epithelial iris cyst (seic) with pus-like precepitates in the cyst. patients and findings: two young men with history of penetrating trauma to the eye and primary repair developed secondary epithelial iris cyst several years later. slit-lamp biomicroscopy revealed a large cyst originating from the site of the laceration. the cyst was filled with pus-like precipitates inferiorly and clear fluid superiorly. contents of the cyst were aspirated and the cysts were treated successfully by chemical cautery with 98% ethanol irrigation. aspirated fluid culture and smear was negative and cytology revealed lymphocysts and epithelial cells. conclusion: pus-like precipitate within iris cyst is a rare presentation which seems to be sterile. treatment with intracystic ethanol irragation is successful in such cases.
