Summary
Selective laser trabeculoplasty (SLT) showed low success rates in a tertiary clinic. Most patients experienced treatment failure within months, with lower baseline IOP predicting poor outcomes.
Area of Science:
- Ophthalmology
- Glaucoma Management
- Surgical Interventions
Background:
- Selective laser trabeculoplasty (SLT) is a common glaucoma treatment.
- Efficacy data from tertiary care centers are crucial for understanding real-world outcomes.
Purpose of the Study:
- To evaluate the effectiveness of selective laser trabeculoplasty (SLT) in a tertiary care setting.
- To identify factors influencing SLT success and failure rates.
Main Methods:
- Retrospective analysis of 94 eyes from 94 patients undergoing SLT.
- Majority (90%) received 180-degree SLT.
- Failure defined by IOP decrease <3 mm Hg or <20% on two visits.
Main Results:
- High overall failure rates: 68% (definition 1) and 75% (definition 2) at initial assessment.
- Mean time to failure was 5.5-6 months.
- By 14.5 months, failure rates reached 86% and 92%.
- Lower baseline intraocular pressure (IOP) was the sole significant predictor of failure.
Conclusions:
- Selective laser trabeculoplasty demonstrated a low success rate in this tertiary clinic population.
- Failure rates for 180-degree SLT ranged from 68% to 74%.
