Primary Vicocanalotomy for Juvenile Open-angle Glaucoma

Purpoe To evaluate the efficacy and afety of primary vicocanalotomy for medically uncontrolled juvenile open-angle glaucoma (JOAG). Deign Propective, noncomparative, interventional cae-erie tudy. Method The tudy included 20 eye of 20 conecutive patient with medically uncontrolled JOAG who were treated by vicocanalotomy at one intitution. No urgical or laer procedure preceded vicocanalotomy. urgical outcome wa defined a an overall ucce by the following criteria: no viual field deterioration, no optic-neuropathy progreion, potoperative intraocular preure IOP ≤20 mm Hg, and IOP reduction ≥30% compared with baeline value with or without medication. When medication were not required, ucce wa defined a complete. Cae that did not fulfill the aforementioned criteria and cae in which a urgical reviion or further goniopuncture wa performed were defined a a failure. Reult Gender ditribution wa imilar. Fourteen eye belonged to the white race; five eye belonged to the black race, and one eye belonged to Arab ethnicity. Mean age (±D) at operation wa 33.77 ± 6.16 year, with the mean preoperative IOP (±D) at 22.9 ± 4.77 mm Hg. Thirty-ix month after operation, 16 cae (80%) were conidered an overall ucce. In 11 cae (55%), ucce wa complete. Four cae (20%) were conidered failure. No eriou complication were documented either during or after operation. In two cae (10%), we documented a pontaneouly reaborbed microhyphema. Trabeculo-Decemet-membrane microperforation occurred in two cae (10%). In two other cae (10%), Trabeculo-Decemet-membrane perforation occurred and wa accompanied by iri prolape that needed peripheral iridectomy. Concluion Primary vicocanalotomy can efficiently and afely reduce intraocular preure in cae of medically uncontrolled JOAG and provide a rational alternative to conventional urgical modalitie.
