IN cataract surgery iridectomy or iridotomy has been done as a general rule since 1864, when von Mooren first introduced it (Bellows, 1944). Different types of iridectomies have been advocated by various surgeons. Chandler in 1890 suggested a pin-hole peripheral iridectomy (Knapp, 1947), and Harrington (1949) also concluded that peripheral iridectomy was better than a complete iridectomy. Kirby...

For the past 12 years peripheral iridectomy has been used as the initial surgical procedure after an acute attack of angle-closure glaucoma. The operation has been performed 2 to 5 days after the pressure has been controlled medically and has been followed routinely by prophylactic peripheral iridectomy in the fellow eye. Peripheral iridectomy for primary acute angle-closure glaucoma controlled...

ALTHOUGH prophylactic peripheral iridectomy is probably one of the most satisfactory operations in the whole of surgery if carefully performed on carefully selected cases, we have the clinical impression that posterior synechiae in the part of the pupil related to the iridectomy can be a common complication. Posterior synechiae following peripheral iridectomy were mentioned by Lowe (1962). The ...

The treatment of acute angle closure glaucoma has been influenced by the development of the YAG laser and its ability to perform iridotomies as an outpatient procedure. In this retrospective study the results of YAG iridotomy were compared with surgical peripheral iridectomy. When compared with surgical peripheral iridectomy patients, YAG iridotomy patients were at greater risk of proceeding to...

purpose: to evaluate the results of one-site phacotrabeculectomy using sutureless tunnel technique without peripheral iridectomy (no-pi) in glaucoma patients with cataract methods: a retrospective study of cases which has been recorded of patients who have had one-site no-pi phacotrabeculectomy using sutureless tunnel technique. we collected pre- and postoperative data in all patients including...

I present a technique designed to ensure an atraumatic patent basal iridectomy for phakic refractive lens implantation. The technique divides the iridectomy procedure into 2 steps. First, the stromal layer is removed by surgical excision. Then, the pigment layer is removed by gentle vacuum aspiration with a 25 gauge cannula. Atraumatic, small, basal peripheral iridectomies that are functional a...

Malignant glaucoma, which is characterized by a shallow or flat anterior chamber with high intraocular pressure, can usually be resolved by pars plana vitrectomy with anterior hyaloidectomy. We describe two cases in which malignant glaucoma was refractory to conventional treatment and complete vitrectomy. Case one an 88-year-old woman with pseudoexfoliation glaucoma underwent trabeculotomy and ...

PURPOSE To study the mechanisms of pupillary block in eyes with occludable angle by ultrasound biomicroscopy. METHODS Initially, a pilot study of 13 eyes with acute primary angle-closure without medication was executed. Ultrasound biomicroscopy measurements of the angle, posterior chamber depth and iris thickness were performed in the temporal quadrant under light and dark conditions. Afterwa...
