Summary
This study shows fornix-based trabeculectomy with mitomycin C and an anchoring corneal suture is safe and effective for lowering intraocular pressure in Chinese patients.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
Background:
- Glaucoma management requires effective surgical interventions.
- Fornix-based trabeculectomy is a common glaucoma surgery.
- The anchoring corneal suture technique aims to improve surgical outcomes.
Purpose of the Study:
- To evaluate the safety and efficacy of fornix-based trabeculectomy using the anchoring corneal suture technique.
- To assess outcomes in Chinese patients undergoing this specific surgical procedure.
Main Methods:
- A retrospective case series of 66 eyes from 63 Chinese patients.
- Fornix-based trabeculectomy combined with intraoperative mitomycin C (0.4 mg/mL).
- Conjunctival closure utilized the anchoring corneal suture technique with 9-0 nylon suture.
Main Results:
- Mean intraocular pressure decreased significantly from 26.83 mmHg to 17.74 mmHg (P < 0.001).
- Mean glaucoma medication use decreased from 2.95 to 1.23 (P < 0.001).
- 47% of eyes required no medication post-surgery; 30.3% achieved qualified success. Early wound leakage occurred in 12.1% of eyes, with most resolving conservatively.
Conclusions:
- Fornix-based trabeculectomy with mitomycin C and the anchoring corneal suture technique is safe and effective.
- This surgical approach shows promising results for managing glaucoma in Chinese patients.
- The anchoring suture technique contributes to successful outcomes and minimizes complications.
