[Argon laser peripheral iridoplasty and laser iridectomy for plateau iris glaucoma]

To evaluate the therapeutic effects of a combined laser technique for plateau iris glaucoma.

20 cases (37 eyes) of early plateau iris glaucoma were treated by a laser technique that included argon laser peripheral iridoplasty and argon + Nd:YAG laser iridectomy.

The postoperative follow-up ranged from 8 months to 4 years and 7 months (30 eyes for more than 2 years, mean 2.7 years). 17 cases (32 eyes) obtained satisfactory effects, no acute-attacks were seen in the follow-up, intraocular pressure decreased from 5.8 +/- 1.04 kPa to below 2.74 kPa, peripheral anterior chamber depth increased, angle widened, the iris retracted away from the trabecular meshwork, thus further synechiae of chamber angle were prevented effectively, and the dark room provocative test results turned to negative in 86.7% of cases.

Argon laser peripheral iridoplasty combined argon + Nd:YAG laser iridectomy may be a safe and effective method for treatment of plateau iris glaucoma.
