Glaucoma, Surgical Management
Drs. Alicia Jiang and Emily Zimmerman demonstrate a technique to trim the end of an Ahmed glaucoma valve (AGV) tube prior to repair of a retinal detachment in a patient with a history of congenital rubella complicated by glaucoma and a chronic retinal detachment. A side port blade is used to make an incision into the anterior chamber; afterwards, viscoelastic is injected to separate the tube from the corneal endothelium. A 27-gauge needle is bent and inserted into the anterior chamber, and then a Kelman-McPherson forceps is used to stabilize the tube while inserting the end of the needle into the tube. The tube is trimmed and the end is guided out of the anterior chamber through the initial incision.
