title: Anterior segment ischemia after cyclocryotherapy.
abstract: The syndrome of anterior segment ischemia occurred in three patients as a complication of cyclocryotherapy for hemorrhagic glaucoma. Cryotherapy was applied with a retinal probe (2.5 mm in diameter) for 12 one-minute applications (-60 degrees or -80 degrees C) over the entire 360-degree circumference at the globe. The pathogenesis for this complication may be related, and unique, to chronic ocular ischemia associated with rubeosis iridis.
