Comparison of Bimatoprost Sustained Release (SR) to Selective Laser Trabeculoplasty (SLT) in Adults With Open-Angle Glaucoma or Ocular Hypertension

* Diagnosis of either open-angle glaucoma or ocular hypertension in each eye that require IOP lowering treatment. * In the investigator's opinion, patient's IOP is not adequately managed with topical medication for reasons other than medication efficacy (eg, due to intolerance or nonadherence). * In the investigator's opinion, both eyes can be treated adequately with topical prostamide, prostaglandin, or prostaglandin analog eye drops as the sole therapy if medication was taken as directed, or with SLT monotherapy.

* History of previous laser trabeculoplasty * History or evidence of complicated cataract surgery: eg, surgery resulting in complicated lens placement (such as anterior chamber intraocular lens implant \[IOL\], sulcus IOL, aphakia, etc) or intraoperative complications (such as a posterior capsular tear \[with or without vitreous loss\], substantial iris trauma, etc) or history of phakic IOL insertion for refractive error correction * Intraocular surgery (including cataract surgery) and/or any ocular laser surgery within the 6 months prior to treatment * Previous use of commercially available Bimatoprost SR; concurrent enrollment in another Allergan Bimatoprost SR study; or previous enrollment in which an implant was received.
