Permanent and absorbable sutures used to temporarily occlude glaucoma seton tubes are removed when capsular fibrosis around the plate provides adequate resistance to aqueous outflow. However, the consequences of unsuccessful or incomplete suture removal have not been described, to our knowledge. We report a case of welltolerated long-term retention of 4-0 chromic absorbable suture in a seton tube in the anterior chamber.
Report of a Case.
—Two years after trabeculectomy, a 55-year-old woman with a history of chronic uveitis and secondary glaucoma in her right eye developed an intraocular pressure (IOP) of 33 mm Hg. Medication to treat her included 4% pilocarpine hydrochloride and 0.5% timolol maleate. Examination revealed visual acuity of 20/30+1, trace cell and flare, and a cup-to-disc ratio of 0.9. A Molteno implant was placed superonasally under a fornix-based conjunctival flap with a scleral patch graft over the tube, which was temporarily occluded with a 4-0 chromic
