Goniotomy in comparative study with trabeculotomy AB externo for treatment of primary congenital glaucoma

Thirty eight eyes of 22 patients with primary congenital glaucoma were treated with goniotomy under direct visualization with goniolens [17 eyes] and with trabeculotomy ab externo [21 eyes] between May 1982 and February 1988. A single goniotomy could control the intraocular pressure in seven eyes, [41.2%], while a single trabeculotomy was successful in seventeen eyes, [81%]. Two goniotomies were successful in six eyes, [35.3%] while two trabeculotomies were successful in two eyes, [9.5%]. Three goniotomies were successful in one eye, [5.9%]
