Summary
Postoperative topical mitomycin application after trabeculectomy significantly reduces hypotony risk compared to intraoperative use. This new technique shows promise for preventing severe hypotony complications.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Glaucoma Surgery
Background:
- Persistent hypotony is a serious complication after trabeculectomy when mitomycin is used intraoperatively.
- Mitomycin application aims to enhance surgical outcomes but carries risks.
Purpose of the Study:
- To decrease the incidence of hypotony following trabeculectomy.
- To evaluate a modified mitomycin application technique using lower concentration and topical application to the filtering bleb post-surgery.
Main Methods:
- Prospective study of patients undergoing trabeculectomy with postoperative topical mitomycin (group 1).
- Comparison with historical data of intraoperative mitomycin (group 2) and no mitomycin (group 3).
- Evaluation of preoperative/postoperative data, complications, and need for further surgery.
Main Results:
- Postoperative mitomycin (group 1) showed a lower incidence of hypotony compared to intraoperative use (group 2).
- Severe hypotony (>3 months) occurred only in the intraoperative group (14/22 eyes).
- Choroidal detachment and hypotony maculopathy were exclusively observed in the intraoperative mitomycin group.
Conclusions:
- Postoperative topical mitomycin application following trabeculectomy is associated with a reduced risk of severe, long-standing hypotony.
- This novel application method appears promising for preventing hypotony in specific patient groups.
- Further research may validate this technique for broader clinical use in glaucoma management.
