    Abstract:
    Gonioscopy-assisted transluminal trabeculotomy (GATT) is a minimally invasive ab interno procedure, performed with guidance of an illuminating microcatheter device (iTrack). The pathophysiology of raised intraocular pressure (IOP) in uveitic glaucoma is commonly due to increased resistance at the trabecular meshwork-Schlemm canal. By removing this resistance, GATT can potentially control the IOP. In addition, the ab interno approach avoids violating the conjunctiva and reduces the risk of complications including infection, leak, and hypotony. In this series, we discuss 3 uveitic glaucoma cases secondary to juvenile idiopathic arthritis (JIA) that underwent GATT. Case 1 was a 16-year-old phakic female with a preoperative IOP of 25 to 33 mm Hg had 360-degree GATT; her IOP remained stable at 6 to 10 mm Hg over 14 months. Case 2 was a 23-year-old pseudophakic female with a preoperative IOP of 28 to 34 mm Hg had 180-degree GATT; her IOP reduced to 8 mm Hg over 10 months. Case 3 was an 8-year-old aphakic male with a preoperative IOP of 21 to 32 mm Hg had 360-degree GATT; his IOP remained stable at 13 to 15 mm Hg over 21 months. In our limited case series, GATT is very successful in controlling IOP in young uveitic patients with JIA by surgically targeting the underlying pathophysiology.
