Summary
Mitomycin C (MMC) combined with covered sclerotomy significantly reduced intraocular pressure in glaucoma patients. This minimally invasive procedure improved success rates, with 58% achieving target pressure without medication.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Glaucoma Management
Background:
- Covered sclerotomy is a minimally invasive glaucoma surgery with low complication rates.
- Early bleb fibrosis is a primary challenge limiting surgical success.
- This study evaluates mitomycin C (MMC) in covered sclerotomy for advanced glaucoma.
Purpose of the Study:
- To analyze intraocular pressure (IOP) reduction and one-year success rates after covered sclerotomy with MMC application.
- To compare outcomes with a previous study that did not use MMC.
- To assess the efficacy of MMC in preventing bleb fibrosis.
Main Methods:
- A prospective clinical study involving 76 eyes with advanced glaucoma.
- Covered sclerotomy combined with a 3-minute application of 0.02% MMC.
- Regular IOP and bleb monitoring over 12 months.
Main Results:
- Mean preoperative IOP was 27 mmHg, reduced to 16.2 mmHg after 12 months (40% reduction, p < 0.05).
- Absolute success rate (IOP < 21 mmHg without medication) was 58%; relative success rate (IOP < 21 mmHg with medication) was 71%.
- No MMC-related complications were observed; 29% of eyes required revision or needling.
Conclusions:
- Additional MMC application significantly enhances pressure reduction in covered sclerotomy.
- Covered sclerotomy with MMC improves success rates compared to procedures without antifibrotic agents.
- 58% of patients achieved target IOP without needing glaucoma medication post-surgery.
