Summary
Selective laser trabeculoplasty is as effective as latanoprost for newly diagnosed open-angle glaucoma. This study supports considering selective laser trabeculoplasty as an initial treatment option.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Laser Therapy
Background:
- Open-angle glaucoma is a leading cause of irreversible blindness.
- Intraocular pressure (IOP) reduction is the primary goal in managing glaucoma.
- Current treatments include medical therapy, laser procedures, and surgery.
Purpose of the Study:
- To evaluate selective laser trabeculoplasty (SLT) as an initial treatment for open-angle glaucoma.
- To compare the efficacy and safety of SLT versus latanoprost.
- To assess SLT's role as adjunctive therapy.
Main Methods:
- Prospective, multicenter, nonrandomized clinical trial.
- Patients with newly diagnosed open-angle glaucoma or ocular hypertension were assigned to SLT or latanoprost.
- Follow-up at 1, 3, 6, and 12 months.
Main Results:
- SLT and latanoprost showed comparable IOP reduction (31.0% vs. 30.6%).
- Responder rates (20% IOP reduction) were similar (83% vs. 84%).
- SLT efficacy was independent of angle pigmentation; a contralateral effect was noted.
Conclusions:
- Selective laser trabeculoplasty is equally effective as latanoprost for newly diagnosed open-angle glaucoma.
- SLT is a viable first-line treatment option, regardless of angle pigmentation.
- Nonsteroidal anti-inflammatory drugs and steroids showed similar efficacy post-SLT.
