Ab interno 180-degree trabeculectomy with a dual blade in a patient with refractory primary congenital glaucoma

Abstract

A 13-year-old female patient with refractory primary congenital glaucoma (PCG) in the right eye who had a history of multiple glaucoma operations underwent ab interno 180-degree trabeculectomy with the Kahook Dual Blade (KDB) targeting the nasal and inferior angles. On postoperative day 1, the intraocular pressure (IOP) of the right eye reduced from 43 to 15 mmHg while on medical therapy. The patient maintained this IOP level throughout the 6-month follow-up. Ab interno KDB trabeculectomy targeting both nasal and inferior angles may be an effective and safe procedure for the treatment of PCG even in eyes with a history of previously failed glaucoma procedures.

Treatment of Pediatric Glaucoma

“…KBD has been shown to be effective in the treatment of congenital glaucoma 18–21 . Elhilali and colleagues compared 21 eyes of patients with primary congenital glaucoma that underwent a conventional ab interno goniotomy with a 25-G needle with 21 eyes that underwent a goniotomy with KBD.…”

“…KBD has been shown to be effective in the treatment of congenital glaucoma. [18][19][20][21] Elhilali and colleagues compared 21 eyes of patients with primary congenital glaucoma that underwent a conventional ab interno goniotomy with a 25-G needle with 21 eyes that underwent a goniotomy with KBD. Both groups had a significant reduction of IOP from preoperatively levels, but there were no differences between the conventional goniotomy group and the KBD group.…”
