Summary
Adding mitomycin-C (MMC) to viscocanalostomy (VCO) may enhance surgical success for glaucoma patients. This technique showed improved filtration and potentially wider indications for VCO.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
Background:
- Glaucoma is a leading cause of irreversible blindness.
- Viscocanalostomy (VCO) is a surgical procedure to reduce intraocular pressure (IOP).
- Mitomycin-C (MMC) is an antifibrotic agent used as an adjunct in some ophthalmic surgeries.
Purpose of the Study:
- To compare the efficacy and outcomes of standard viscocanalostomy (VCO) versus VCO with intraoperative mitomycin-C (MMC).
Main Methods:
- A retrospective comparison of 15 standard VCO cases (Group 1) with 15 prospective VCO cases using intraoperative MMC (Group 2).
- MMC was applied to the scleral flap for 3 minutes.
- Patients were followed for at least 1 year, with IOP < or = 18 mmHg defined as surgical success.
Main Results:
- Both groups showed significant IOP reduction (p<0.001).
- The MMC group (Group 2) had a higher complete success rate (67%) compared to the standard VCO group (Group 1) (40%).
- Conjunctival bleb morphology differed significantly, with thin-walled, avascular blebs more common in the MMC group.
Conclusions:
- Intraoperative MMC may improve long-term outcomes in viscocanalostomy by enhancing subconjunctival filtration.
- The use of MMC could potentially broaden the applicability of the VCO technique for glaucoma management.
