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. © 2022 The Authorseninfo:eu-repo/semantics/openAccessCongenital glaucomaGonioscopy – assisted transluminal trabeculotomyKlippel – Trenaunay - Weber SyndromeArticleQ328
