This prospective case series evaluated the 12-month outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) in children with glaucoma following cataract surgery (GFCS). Glaucoma following pediatric cataract surgery is a recognized postoperative complication that may require surgical management when medical therapy is insufficient. Gonioscopy-assisted transluminal trabeculotomy (GATT) is a minimally invasive conjunctiva-sparing procedure designed to improve aqueous outflow through circumferential trabeculotomy. This prospective interventional case series will evaluate outcomes of GATT in eligible pediatric patients with glaucoma following cataract surgery treated at Cairo University Hospitals. Participants will undergo preoperative ophthalmic assessment, standardized surgical intervention, and scheduled postoperative follow-up visits. Outcomes to be assessed include intraocular pressure, use of glaucoma medications, and safety parameters during follow-up.
12-month Outcome of Gonioscopy-assisted Transluminal Trabeculotomy in Pediatric Glaucoma Following Cataract Surgery. Abstract Introduction Glaucoma following cataract surgery (GFCS) represents the most common vision-threatening complication after pediatric lensectomy, frequently necessitating surgical management. While ab-externo circumferential trabeculotomy has yielded promising results in previous studies, gonioscopy-assisted transluminal trabeculotomy (GATT) offers a minimally invasive, conjunctiva-sparing ab-interno approach for circumferential angle incision. This study evaluated the outcome of GATT in children diagnosed with GFCS. Methods This prospective interventional case series included 30 eyes of 24 pediatric patients (aged 0.5-13 years) diagnosed with GFCS. We excluded eyes with opaque corneas, extensive synechial angle closure, eyes in which \>180° incision could not be achieved and patients who could not complete a 12-month follow-up period. The primary outcomes were IOP reduction and changes in number of antiglaucoma medications; secondary outcomes were surgical success and complications. Success was defined as final IOP ≤21 mmHg without further glaucoma intervention and absence of vision-threatening complications.

The operating microscope is tilted 45 degrees,, the head of the bed is elevated, and the head of the patient is tilted to the opposite side. While sitting on the temporal side of the patient a temporal corneal incision is created by a 23 Gauge MVR. An inferior or superior paracentesis is created. The anterior chamber (AC) is filled using cohesive viscoelastic then the angle is visualized by direct gonioscopy using Swan Jacob lens. Nasal goniotomy for 2 clock is performed by using MVR blade to incise the inner wall of Schlemm's canal. Cohesive OVD is used to open the lips of the incision, then 5/0 prolene after being blunted by cautery pen is threaded inside Schlemm's canal guided it inside the canal using 23-gauge vitreoretinal forceps until we retrieve it from the opposite end of the incision. The two ends of the 5/0 prolene suture are pulled to incise the Schlemm's canal and trabecular meshwork over 360°.The AC is washed by BSS followed by injection of air to tamponade any bleeding t
