Summary
Selective laser trabeculoplasty (SLT) effectively lowers intraocular pressure and medication use in Brazilian patients. Denser angle pigmentation and post-SLT corticosteroid use predict better treatment outcomes.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Laser Therapy
Background:
- Selective laser trabeculoplasty (SLT) is a common treatment for glaucoma.
- Real-world data on SLT outcomes in diverse populations is crucial for clinical decision-making.
Purpose of the Study:
- To evaluate the real-world effectiveness of primary selective laser trabeculoplasty (SLT) in Brazil.
- To identify predictors of treatment success and failure in a large cohort of Brazilian glaucoma patients.
Main Methods:
- Multicenter retrospective case series including 835 eyes from 835 patients undergoing primary SLT.
- Analysis of intraocular pressure, medication use, visual acuity, and visual field over a mean follow-up of 916.8 days.
- Kaplan-Meier survival analysis and multivariable modeling to identify success predictors.
Main Results:
- Significant reduction in intraocular pressure (18.4 to 14.8 mmHg) and glaucoma medications (1.8 to 1.4).
- Treatment success probability was 88% at 12 months, decreasing to 54% at 36 months.
- Denser angle pigmentation (HR 0.69) and post-SLT corticosteroid treatment (HR 0.59) were associated with a lower risk of failure.
Conclusions:
- Primary SLT demonstrates high success rates and a favorable safety profile in a large Brazilian patient cohort.
- Findings support SLT as an effective glaucoma treatment and provide insights into patient selection.
- Denser angle pigmentation and judicious use of corticosteroids post-SLT may enhance treatment longevity.

Open Angle Glaucoma: Treatment
741
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
874
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Glaucoma: Overview
947
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
