Ocular Hypertension Glaucoma

This study looks at a new laser treatment for people with high eye pressure or a type of glaucoma called open-angle glaucoma. All patients in the study have already had a similar laser treatment before (called SLT). In this study, everyone will receive the same treatment, called Direct Selective Laser Trabeculoplasty (Voyager™ DSLT). This device is approved by the FDA and will be used as directed. The goal is to understand how safe it is and how well it works in these patients. Glaucoma is a major cause of permanent vision loss. A common treatment, called SLT, uses a laser to help lower pressure inside the eye. The newer treatment, DSLT, works in a similar way but does not touch the eye, which may make it quicker and more comfortable. DSLT has worked well in patients who have never had laser treatment before, but there is not much information about how well it works in people who have already had SLT. The main goal of this study is to see how much the treatment lowers eye pressure after 6 months, compared to before treatment. To get accurate results, patients will stop their usual glaucoma eye drops for a short time before their eye pressure is measured. This helps show the true effect of the laser treatment. The study will also look at other outcomes. These include how much eye pressure drops in percentage terms, how many patients have successful results, and whether patients can reduce the number of glaucoma medications they use. It will also track if any patients need additional glaucoma treatments later.
