%X <B>OBJECTIVE: </B>The RiGOR study's primary outcome measure was a 15% reduction in intraocular pressure (IOP) for patients with open-angle glaucoma at 1 year.<BR><B>METHODS: </B>Patients received treatment according to the ophthalmologist's usual practice.<BR><B>RESULTS: </B>A higher proportion of patients in the incisional and other surgery group achieved a 15% reduction in IOP than in the laser surgery or additional medication groups (82, 57, and 57% respectively). In multivariate regression analyses, incisional surgery patients were 2.7-times as likely as patients treated with additional medication to achieve a 15% reduction in IOP (odds ratio: 2.67; 95% CI: 2.01-3.57).<BR><B>CONCLUSIONS: </B>Incisional and other surgical procedures are effective treatments. There were no differences in treatment response by race or ethnicity.
