[Experiences with transtrabecular iridectomy]

A transtrabecular iridectomy was performed in 17 eyes with narrow angle glaucoma, and in 3 eyes in which the trabecular meshwork was gonioscopically not visible. Postoperatively, the conjunctive lied directly on the sclera in 14 cases; in 6 cases a circumscribed conjunctival bleb developed in the operation field. After a follow-up of 12 or 24 months, the intraocular pressure was normalized without miotics in 15 of 17 eyes. The mechanism of transtrabecular iridectomy is discussed.
