Summary
Nd: YAG laser iridotomy is a safe and effective treatment for primary angle-closure glaucoma, successfully relieving pupil block in 130 eyes. Postoperative complications were minor and did not impact visual acuity.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Laser Therapy
Context:
- Primary angle-closure glaucoma (PACG) is a leading cause of irreversible blindness.
- Pupil block is a critical mechanism in PACG pathogenesis.
- Effective and safe interventions are needed to manage PACG.
Purpose:
- To evaluate the efficacy and safety of Nd: YAG laser iridotomy in eyes with primary angle-closure glaucoma.
- To assess the long-term patency of iridotomies and relief of pupil block.
- To document the incidence and impact of potential complications.
Summary:
- 130 eyes with primary angle-closure glaucoma underwent successful Nd: YAG laser iridotomy.
- Iris perforations remained patent from 1 week to 8 months post-procedure, effectively relieving pupil block.
- Common complications included transient peripheral corneal opacity, mild iris hemorrhage, and temporary intraocular pressure (IOP) elevation, none affecting visual acuity.
Impact:
- Nd: YAG laser iridotomy provides a safe and effective treatment option for primary angle-closure glaucoma.
- The procedure demonstrates sustained efficacy in relieving pupil block.
- Minimal complications suggest a favorable safety profile for this intervention.
