Clinical Result of Trabeculotomy(ab externo)

• Lee SH

Abstract

The introduction of microsurgical techniques in trabeculotcmy ab externo led to further improvement in the control of intraocular pressure of developmental glaucoma and glaucoma in young adults. Trabeculotomies were performed in 23 eyes: 7 eyes with congenital glaucoma, and 6 eyes with infantile glaucoma, and 10 eyes with juvenile glauccma or primary open-angle glaucoma in young adults. Five eyes of the cases had previous filtering operation. Intraocular pressure was controlled in 7 eyes(100.0%) with congenital glaucoma, 5 eyes(83.3%) with infantile glaucoma, and 8 eyes(80.0%) with juvenile glaucoma or glaucoma in young adults, with/without less medication. The average reduction of IOP was 17.9 mmHg after the operation. A strong statistical relationship was present between the success of the operation and low C/D ratio or no history of previous filtering operation, and the success was not dependent on the high IOP, the size of corma, and age of onset.
