Summary
Large-area mitomycin C (MMC) application during trabeculectomy surgery led to greater intraocular pressure reduction and higher success rates compared to small-area application. However, it was associated with more frequent complications.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
Background:
- Trabeculectomy is a common surgical procedure for glaucoma.
- Mitomycin C (MMC) is frequently used to enhance surgical outcomes.
- Optimizing MMC application is crucial for improving trabeculectomy efficacy.
Purpose of the Study:
- To compare the efficacy and safety of small-area versus large-area mitomycin C (MMC) application during trabeculectomy.
Main Methods:
- Retrospective analysis of 191 eyes undergoing trabeculectomy with either small-area (96 eyes) or large-area (95 eyes) MMC application.
- Outcomes assessed included intraocular pressure (IOP) reduction, medication needs, complication rates, and postsurgical interventions.
Main Results:
- Both groups showed significant IOP reduction (p < 0.0001).
- Large-area MMC application resulted in greater IOP reduction in the first postoperative year and a higher success rate at 12 months.
- The large-area group experienced more choroidal detachment, shallow anterior chamber, and bleb leaks.
- The small-area group had higher rates of bleb scarring and failure.
Conclusions:
- Large-area MMC application appears more effective in reducing IOP and improving trabeculectomy success rates.
- The increased efficacy of large-area MMC application must be balanced against a higher risk of certain early postoperative complications.
