Abstract
PURPOSE: To describe the case of a 9-year-old boy with congenital glaucoma secondary to Klippel - Trenaunay - Weber Syndrome (KTW) with a history of trabeculotomy in both eyes (BE) and further trabeculectomy in the left eye (LE) presented with high intraocular pressure (IOP) and progression in the LE despite maximum tolerated medical therapy. OBSERVATIONS: GATT surgery was performed firstly in the LE, followed by the right eye (RE) two months apart since the IOP in the RE started to increase later on. First post-operative day the IOP was under 15 mmHg. In the last visit, 6 months after the first surgery, IOPs were 10 and 11 mmHg RE and LE, on one fixed combination; slit lamp examinations were normal with wide open angles and a good view of the Schlemm's Canal (SC) posterior wall. CONCLUSIONS AND IMPORTANCE: GATT surgery can be done after failed incisional surgery in children with glaucoma secondary to KTW syndrome.
