The new clinical finding of an iris cyst can cause diagnostic and management uncertainty.1-3 Iris cysts are uncommon and can be primary or secondary as well as benign or malignant.2-4 Management options for benign secondary iris cysts include observation, drainage, surgical excision, cryoablation, photocoagulation, or even intracystic irrigation of a cytotoxic agent such as ethanol.3,5,6 We report a case series of 4 secondary iris cysts in 4 patients, all successfully managed with endophotocoagulation assisted with viscoelastic.2
The patients included 2 males and 2 females, with a mean age of 36.8 years (range, 4-83 years). Three cases had a definitive history of preceding trauma, and the other was uncertain. The cyst was located superiorly in 3 cases and inferonasally in the fourth. The largest cyst diameter ranged between 4 and 5 mm in all cases. The main indication for surgery was visual symptoms (Figure and Table).
