SLT, latanoprost equally effective at lowering IOP

Selective laser trabeculoplasty and latanoprost are “equally efficacious” in reducing IOP in patients with newly diagnosed open-angle glaucoma and ocular hypertension, according to a study.

Ian McIlraith, MD, and colleagues prospectively assigned 100 eyes of 61 patients with newly diagnosed open-angle glaucoma or ocular hypertension to receive selective laser trabeculoplasty (SLT) or latanoprost according to patient choice. Both groups were followed up at 1, 3, 6 and 12 months. Of the eyes, 74 underwent SLT and 26 preferred the medical treatment regimen.

Eyes that underwent SLT had an average 8.3 mm Hg reduction in IOP, or about 31%. Eyes on latanoprost had a 7.7 mm Hg reduction in IOP, or about 30.6%.

There were “no differences” in IOP lowering with SLT on the basis of angle pigmentation, the researchers said.

The study is published in the April issue of the Journal of Glaucoma.
