Summary
Long-term trabeculectomy success in chronic open-angle glaucoma relies on a functional filtering bleb. While cataracts are common, especially in older patients, bleb presence is key for sustained intraocular pressure control.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Outcomes
Context:
- Trabeculectomy is a common surgical procedure for managing glaucoma.
- Primary chronic open-angle glaucoma (COAG) is a leading cause of irreversible blindness.
- Long-term follow-up data is crucial for understanding surgical efficacy.
Purpose:
- To evaluate the long-term efficacy and complications of trabeculectomy in primary chronic open-angle glaucoma.
- To identify factors associated with sustained intraocular pressure stabilization after surgery.
Summary:
- This study analyzed 93 trabeculectomy cases in primary chronic open-angle glaucoma patients with 2-11 years of follow-up.
- Effective subconjunctival filtering bleb formation was strongly correlated with long-term intraocular pressure stabilization.
- Cataract development occurred in 46% of cases, influenced by patient age, typically within 1-3 years post-surgery.
Impact:
- Findings highlight the critical role of filtering bleb maintenance for enduring glaucoma control.
- Understanding long-term outcomes aids in patient counseling and surgical planning.
- Identifies cataract formation as a significant, age-related complication requiring monitoring.
