Summary
Noncontact transscleral Nd:YAG laser cyclocoagulation is a relatively effective treatment for uncontrolled glaucoma. While some patients experienced transient pain and inflammation, the procedure demonstrated good tolerability and efficacy in managing intraocular pressure.
Area of Science:
- Ophthalmology
- Medical Procedures
Background:
- Glaucoma is a leading cause of irreversible blindness worldwide.
- Uncontrolled glaucoma often requires advanced treatment modalities to preserve vision.
Purpose of the Study:
- To evaluate the efficacy and safety of noncontact transscleral Nd:YAG laser cyclocoagulation.
- To assess the procedure's effectiveness in managing various forms of uncontrolled glaucoma.
Main Methods:
- Retrospective review of 25 patients (25 eyes) who underwent the procedure.
- Application of 13-35 pulses (mean 22.7) at 1-2 mm behind the limbus with 3.4-8.2 J energy (mean 4.5 J).
- Follow-up duration ranged from 6 to 23 months.
Main Results:
- 36% of eyes required repeat treatments.
- 48% of eyes achieved intraocular pressure < 21 mm Hg and > 4 mm Hg.
- 40% experienced transient moderate to severe pain.
- 40% developed transient substantial inflammation.
Conclusions:
- Noncontact transscleral Nd:YAG laser cyclocoagulation shows relative efficacy in treating uncontrolled glaucoma.
- The procedure is generally well-tolerated, despite potential transient side effects like pain and inflammation.
