OBJECTIVE: To determine the reduction in intraocular pressure (IOP) of multiple selective laser trabeculoplasty (SLT) in eyes with open-angle glaucoma (OAG) and ocular hypertension (OHT). METHODS: Forty-nine OAG eyes that received multiple SLTs were retrospectivel]j studied. The first and second SLT treated 180 degrees and the third treat! 180 to 360 degrees of the trabecular meshwork. Main outcome (response rate)] was IOP reduction of a3 mm Hg from baseline at 6 months after each SLT.Only patients followed up for at least 6 months were included. CONCLUSION: Multiple selective SLT successfully lowers IOP. A second SLT lowered IO1 by 19 percent from baseline IOP after 6 months and a third by 47 percent after another f months. Eyes with baseline IOP >21 mm Hg had greater IOP reduction; higher response rates for each SLT compared to those with baseline IOP ? 21 mm Hg.
