title: Comparative study of argon laser trabeculoplasty in primary open-angle and pseudoexfoliation glaucoma.
abstract: In 93 phakic eyes--52 eyes with primary open-angle and 41 eyes with exfoliation glaucoma--with increased intraocular pressure, argon laser trabeculoplasty was performed. Fifty to sixty burns were made over 180 degrees of the lower trabecular meshwork. During the follow-up period, visual acuity, intraocular pressure, medication changes and the need for surgery were studied. In 25 eyes a second laser treatment was performed over 180 degrees of the upper trabecular meshwork. Intraocular pressure control was obtained in 81% of the eyes with primary open-angel glaucoma and 71% of the eyes with pseudoexfoliation glaucoma. The average reduction of pressure obtained after laser trabeculoplasty was 9.22 mm Hg for the group of eyes with primary open-angle glaucoma and 13.42 mm Hg for the group of eyes with pseudoexfoliation glaucoma (p less than 0.001). Reduction in medical treatment was obtained in 27 eyes from the 71 eyes with successful reduction of the intraocular pressure. In 6 eyes with successful results after argon laser trabeculoplasty, cataract extraction was performed. The intraocular pressure remained normal in all eyes after the operation.
