We report a case of an 84-year-old man who had an Ex-PRESS R-50 glaucoma shunt placed under a scleral flap in his right eye for primary open angle glaucoma and uncontrolled intraocular pressure. Twenty-one days after placing the implant, the patient returned with a dislocated shunt resting in the inferior angle of the anterior chamber. Corrected vision was 20/30 with an intraocular pressure of 13mm Hg. There was no anterior chamber inflammation and no evidence of corneal decompensation. To our knowledge, this is the first report of an Ex-PRESS shunt dislocation into the anterior chamber. Ophthalmologists implanting this device should be aware of this possible complication of Ex-PRESS shunt insertion.
