Summary
Two surgical methods for repairing late-onset bleb leaks after trabeculectomy show similar effectiveness. Bleb de-epithelialization requires fewer glaucoma medications post-surgery compared to bleb excision.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Techniques
Background:
- Trabeculectomy is a common glaucoma surgery.
- Late-onset bleb leaks can occur after trabeculectomy, potentially leading to complications.
- Effective surgical repair is crucial for managing bleb leaks and maintaining intraocular pressure control.
Purpose of the Study:
- To compare the outcomes of two surgical techniques for repairing late-onset bleb leakage following trabeculectomy.
- To evaluate the efficacy and safety of bleb excision versus bleb de-epithelialization with conjunctival advancement.
Main Methods:
- Retrospective study of 21 eyes (20 patients) with late-onset bleb leaks post-trabeculectomy.
- Group 1: 14 eyes underwent bleb excision and conjunctival advancement.
- Group 2: 7 eyes underwent bleb de-epithelialization and conjunctival advancement.
Main Results:
- No significant difference in complete, qualified, or overall success rates between the two groups (P>0.05).
- Mean follow-up was 20.3 months.
- The bleb excision group required significantly more antiglaucoma medications (P=0.02).
Conclusions:
- Both bleb repair techniques are comparably effective in resolving leakage and achieving target intraocular pressure.
- Bleb de-epithelialization is associated with a reduced need for postoperative glaucoma medications.
