What this study is about
The goal of this clinical trial is to to evaluate how well Direct Selective Laser Trabeculoplasty (DSLT) lowers eye pressure in eyes of adult, non-Caucasian participants with primary open angle glaucoma.
View original scientific description
The goal of this clinical trial is to to evaluate how well Direct Selective Laser Trabeculoplasty (DSLT) lowers eye pressure in eyes of adult, non-Caucasian participants with primary open angle glaucoma. The main question it aims to answer is: What is the washed out eye pressure (eye pressure when not on any glaucoma medications) of participants 6 months after the Direct Selective Laser Trabeculoplasty (DSLT) procedure compared to the washed out eye pressure of participants prior to the DSLT procedure. Participants will: Undergo the DSLT procedure in one or both eyes and visit the clinic 1 month, 3 months, and 6 months after the procedure to have their vision and eye pressure measured.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Adult patients of Black African descent scheduled to undergo DSLT treatment in one or both eyes.
- Diagnosis of mild to moderate primary open angle glaucoma (POAG).
- Mild to moderate POAG will be defined as Stage 2 or better of the Hodapp-Anderson-Parrish glaucoma staging system.
- Treatment naive or washed out IOP at time 0 ranging from ≥ 21 through 32 mm Hg.
Exclusion criteria
- 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).
- Secondary glaucoma:
- 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.
- Subjects who are pregnant, breast-feeding, or intend to become pregnant during the study period as determined by verbal inquiry.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
