—Cyclocryotherapy, which decreases intraocular pressure by disrupting the function of the ciliary processes with a resultant decrease in aqueous humor production, is used to treat refractory glaucoma.1-3 A number of well-known complications may occur following this procedure.1,2 We observed a patient who developed massive subretinal fibrosis following cyclocryotherapy.
Report of a Case.
—A 62-year-old man with chronic open angle glaucoma in both eyes had uncontrolled intraocular pressure in the right eye despite maximum medical therapy and three unsuccessful filtration procedures; cyclocryotherapy was therefore performed on this eye. The intraocular pressure decreased from 37 to 6 mm Hg, and large choroidal effusions were noted. The choroidal effusions slowly diminished with a regimen of 1% atropine sulfate given twice daily and frequent use of topical prednisolone acetate.The patient was unavailable for follow-up evaluation between the sixth and 12th weeks postoperatively. During this time, his visual acuity
