An observational study in Primary Open Angle Glaucoma and Ocular Hypertension, sponsored by The Eye Institute of West Florida. Recruiting at 1 site in United States. Per ClinicalTrials.gov, last updated 2026-04-20.
Sponsored by The Eye Institute of West Florida · Observational
This is a prospective, single arm, open label study conducted at a single site to evaluate the efficacy of Direct Selective Laser Trabeculoplasty (DSLT) in reducing medication burden in patients with medically controlled ocular hypertension or primary open angle glaucoma.
The study will assess the primary endpoint of reduction in medication count at 6 months compared to baseline. Secondary endpoints include IOP reduction compared to baseline (both percentage and absolute), complete success rate (no increase in IOP without medications), proportion of eyes needing medication at 6 months, and any secondary surgical interventions at 6 months post-DSLT.
Participants will undergo DSLT with 120 shots, 400 µm spot size, and 1.8mJ fixed energy delivered at the limbus over 2.4 seconds. Follow-up visits will occur at 1 month, 3 months, and 6 months post-procedure, with IOP measured using a calibrated Goldmann tonometer.
924 studies on the registry are indexed under Glaucoma, Open-Angle; 117 are open to participants now.
This study's planned enrollment of 60 is below the median of 101 across 184 observational studies indexed under Glaucoma, Open-Angle.

Adult patients scheduled to undergo DSLT treatment in one or both eyes.
Exclusion Criteria:
Previous glaucoma surgeries/interventions:
Secondary glaucoma:
Voyager DSLT
Reduction in the number of glaucoma medications required to maintain target intraocular pressure (IOP)
The primary outcome will be assessed by comparing the number of medications needed to maintain target IOP before and after DSLT treatment.
Time frame: 6 months post-DSLT treatment
Change in intraocular pressure (IOP) from baseline
IOP will be measured using Goldmann applanation tonometry at each follow-up visit.
Time frame: 6 months post-DSLT treatment
Proportion of eyes needing medication stratified by number of IOP medications required
Time frame: 6 months post-DSLT treatment
Number and type of Secondary surgical interventions
Time frame: 6 months post-DSLT treatment
Started Feb 2026 (actual). Primary completion is estimated for Jan 2027, 11 months after the start.
Of 53 observational studies under Glaucoma, Open-Angle, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 12. This study's planned 11 months is below that.
