We present a novel ab externo glaucoma device occlusion method for patients with hypotony following glaucoma drainage device placement. In this case study, a patient with symptomatic hypotony due to cyclophotocoagulation after glaucoma drainage device implantation underwent occlusion of the drainage device via a modified ab externo approach. After externalizing the tube through a corneal paracentesis incision, a bulbed 3-0 polypropylene suture fragment was inserted into the tube, with subsequent reinsertion of the occluded tube into the anterior chamber. Intraocular pressure increased from 4 mmHg to teens in the first month after the procedure, peaking at 18mmHg at post-operative month four, and stabilizing at 10mmHg on dorzolamide at 14 month follow-up. Visual acuity improved from 20/1000 to 20/400. The technique improves upon previously-described occlusive methods owing to its technical simplicity, safety, minimal invasiveness, and reversibility.
