The authors reviewed the outcome of trabeculotomy for congenital glaucoma associated with dysgenesis of anterior ocular segment in 13 eyes of seven cases. Sclerocornea was present in all 13 eyes. Other anomalies included posterior embryotoxon (six eyes), congenital iris ectropion (three eyes), Peters' anomaly (two eyes), and sectorial iris heterochromia (one eye). Control of intraocular pressure was obtained after one session of trabeculotomy in seven eyes. The other six eyes, which had either Peters' anomaly or iris ectropion, had to be treated by additional surgery. These findings show that the effect of trabeculotomy may differ depending on the type and severity of associated ocular anomalies.
