[External trabeculotomy in the treatment of developmental glaucoma: a clinical report on 140 eyes of 88 cases].

: 140 eyes of 88 cases with developmental glaucoma including 128 eyes of 80 cases with infantile glaucoma and 12 eyes of 8 cases with juvenile glaucoma were treated by external trabeculotomy. The success rate of the operation is 73.9% and by addition of small amount of topical antiglaucoma agent the rate of glaucomatous control reaches to 86.4%, the average period of follow-up being 15.2 months. The complications of the operation are few and mild in degree. The important steps of the operative procedure and the critical points of the post-operative management were described, the therapeutic effect of the operation was evaluated and the factors which possibly can affect the prognosis of the operation were analyzed. It is recognized that the operation is better than goniotomy. We recommend external trabeculotomy for treatment of developmental glaucoma which is especially suitable for primary infantile glaucoma.
