We treated 54 eyes of 51 patients with refractory glaucoma by using contact transscleral Neodymium: YAG laser cyclophotocoagulation; 32 burns (7 watts during 0.7 second) were applied to each eye by positionning the anterior edge of the probe at 0.5 to 1 mm from the limbus. The mean preoperative intraocular pressure (IOP) was 33.7 mmHg and the mean postoperative IOP was 25.6 mmHg with a follow-up of five months. There was a decrease of IOP in 72.3% of the cases. The postoperative IOP was controlled (IOP < 21 mmHg) in 41.3% of the treated eyes. Pain decreased in 6.7% of the cases that had no control of IOP and they could stop their medical treatment. During the follow-up period we observed neither early post operative hypertonia nor phtisis bulbi. Three eyes had scleral perforations. Laser treatment can be repeated if necessary in no controlled IOP cases. We had less complications with the laser treatment than with cyclocryoapplication. We described the advantages of the contact probe used.
