Abstract |
We investigated the effect of trabeculoplasty using Q-switched,frequency doubled Nd: YAG laser (Selecta 7000, Coherent,U.S.A.) which was developed to selectively destroy pigmented trabecular meshwork cells without producing collateral or thermal structural damage to adjacent structure. Twenty eyes of 14 patients with medically uncontrolled primary open angle glaucoma were enrolled in this study. The mean prelaser intraocular pressure (IOP) was 20.5 +/-5.0 mmHg (12-32mmHg) and the decrease of IOP was 5.8 +/-5.3 mmHg (26.7%) at 1 week, 5.9 +/-3.7 mmHg (27.7%)at 1 month and 5.4 +/-4.7 mmHg 22.9%) at 6 months. Moderate anterior chamber inflammation was noted in 7 cases but resolved in 1 week and peripheral anterior synechia was not noted in any case until 6 months. |
