Direct Selective Laser Trabeculoplasty (DSLT) for Patients With Glaucoma or Ocular Hypertension Previously Treated With SLT

Starting soon · Not applicable

Conditions studied: Ocular Hypertension Glaucoma, POAG

In brief

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.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• • Adult patients (18-80 years old), scheduled to undergo DSLT treatment in one eye.
• Diagnosis of ocular hypertension (OHTN) or primary open angle glaucoma (POAG).
• Previous history of selective laser trabeculoplasty (SLT) treatment. • Medication free or washed out IOP at time 0 ranging from ≥ 18 through 32 mm Hg.

You may not qualify if…

• • Screened patients who were on IOP-lowering medications who did not successfully complete medication washout at the time of the procedure (time 0)
• Previous glaucoma surgeries/interventions:
• Patients who have undergone prior glaucoma-related procedures (e.g., trabeculectomy, laser trabeculoplasty, MIGS, or tube shunt).
• Recent SLT failures (within 6 months of initial treatment).
• Patients who have undergone cataract surgery within the prior 2 years.
• Secondary glaucoma:
• o Patients with secondary forms of glaucoma, such as angle-closure glaucoma, neovascular glaucoma, or glaucoma resulting from trauma or other systemic diseases.
• Other significant ocular conditions including advanced cataracts, retinal diseases (e.g., age-related macular degeneration), or any condition that might complicate the assessment of intraocular pressure (IOP) or visual function as deemed by the investigator.
