This is a tough case of a patient with Granulomatosis with Polyangiitis (formerly known as Wegener's Granulomatosis). He also has a history of high myopia. In his other eye, he has a history of retinal detachment requiring a scleral buckle and tube shunt implantation for refractory glaucoma. Over time, both of these developed recurrent erosion/exposure, leaving him essentially monocular. He was referred with medically-uncontrolled glaucoma in his better-seeing eye. Given his prior history, we opted to try a canal-based procedure to avoid the issues of erosion. We chose Ab Interno Canaloplasty since he was monocular, and we wanted to reduce the risk of hyphema.
