[Argon laser trabeculoplasty--long-term results]
1Ocná klinika LF UPJ, Kosice.
Summary
Argon laser trabeculoplasty (ALT) effectively lowers intraocular pressure in primary open-angle glaucoma (POAG). However, its long-term efficacy diminishes significantly over time, with success rates dropping substantially after 10 years.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Interventions
Context:
- Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness worldwide.
- Argon laser trabeculoplasty (ALT) is a common surgical option for managing POAG.
- Long-term effectiveness data for ALT in POAG patients is crucial for clinical decision-making.
Purpose:
- To evaluate the long-term success rate and efficacy of argon laser trabeculoplasty (ALT) in patients with primary open-angle glaucoma (POAG).
Summary:
- A study analyzed 302 eyes of 175 POAG patients post-ALT, with follow-up up to 10 years.
- Success was defined as intraocular pressure (IOP) < 21 mmHg without optic disc or visual field progression.
- Success rates were 81.8% at 2 years, 64.4% at 5 years, 27.8% at 8 years, and 15.6% at 10 years.
Impact:
- Confirms ALT's initial effectiveness in POAG management.
- Highlights a substantial decline in ALT efficacy over extended follow-up periods.
- Suggests the need for re-evaluation of long-term glaucoma treatment strategies.
