Summary
Fixed high-energy selective laser trabeculoplasty (SLT) significantly reduces intraocular pressure (IOP) more than the standard titrated approach. This method is safe and effective, especially for patients not on glaucoma medications.
Area of Science:
- Ophthalmology
- Glaucoma Management
- Laser Therapy
Background:
- Selective Laser Trabeculoplasty (SLT) is a common glaucoma treatment.
- Optimal laser energy settings for SLT remain debated.
- This study compares fixed high-energy SLT to the standard titrated approach.
Purpose of the Study:
- To compare the efficacy of fixed high-energy SLT versus standard titrated-energy SLT.
- To evaluate outcomes within a residency training program setting.
- To assess intraocular pressure (IOP) reduction and medication use.
Main Methods:
- Retrospective review of 354 eyes undergoing SLT between 2011-2017.
- Comparison of fixed high-energy (1.2 mJ/spot) SLT with standard titrated SLT (starting at 0.8 mJ/spot).
- Exclusion of patients with prior SLT history and repeat treatments.
Main Results:
- Fixed high-energy SLT showed significantly greater IOP reduction at 12 and 36 months postprocedure.
- In medication-naïve patients, fixed high-energy SLT yielded significantly greater IOP reduction at all time points.
- Complication rates (IOP spike, iritis, macular edema) were similar between groups.
Conclusions:
- Fixed-energy SLT is as effective as the standard-energy approach without increasing adverse events.
- Fixed-energy SLT demonstrated superior IOP reduction in medication-naïve patients.
- Results suggest fixed high-energy SLT may be a more effective treatment option.
