Treatment of recurrent giant iris cyst with intracyst administration of mitomycin C

COMMENT Photocoagulation of iris implantation cysts can induce a rise in IOP believed to be due to clogging of the trabecular meshwork by released viscous contents of the cyst. 2 Moreover, since the original structure and function of the epithelial lining of the cyst remains fundamentally unchanged, recurrence after photocoagulation is common. 2 Total surgical excision may be performed, although the cyst can be adherent to the posterior surface of the cornea and excessive surgical manipulation may induce epithelial downgrowth.
