Aims:
The aim of this study was to evaluate the efficacy of mitomycin C in reducing postoperative adhesions following strabismus surgery.
Methods:
This study was a prospective, single-center, interventional case series. We randomized 14 patients with restrictive strabismus to the mitomycin C group (7 patients) or to the control group (7 patients). We used mitomycin C intraoperatively for 5 min at a concentration of 0.2 mg/mL in the mitomycin group after adhesion release. We compared postoperative results using the forced duction test.
Results:
Compared to the control group, the mitomycin C group exhibited a better range of passive duction at all postoperative follow-up times; however, mitomycin C did not completely eliminate the problem of postoperative adhesions. Patients receiving mitomycin C did not report any complications during this study.
Conclusions:
The intraoperative application of mitomycin C is a safe and effective adjunct to surgery in the treatment of restrictive strabismus.
Insights
Mitomycin C effectively reduced postoperative adhesions in strabismus surgery patients, improving passive duction range without complications. While not a complete solution, it proved a safe and beneficial addition to surgical treatment.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Pharmacology
Background:
- Postoperative adhesions are a common complication following strabismus surgery.
- These adhesions can lead to restrictive strabismus and negatively impact surgical outcomes.
- Mitomycin C is an antifibrotic agent with potential to inhibit adhesion formation.
Purpose of the Study:
- To assess the efficacy of intraoperative mitomycin C in preventing postoperative adhesions after strabismus surgery.
- To evaluate the safety and impact of mitomycin C on passive duction range post-surgery.
Main Methods:
- A prospective, single-center, interventional case series involving 14 patients with restrictive strabismus.
- Patients were randomized into two groups: mitomycin C (n=7) and control (n=7).
- Mitomycin C (0.2 mg/mL for 5 minutes) was applied intraoperatively in the treatment group; forced duction tests were used for comparison.
Main Results:
- The mitomycin C group demonstrated an improved range of passive duction compared to the control group across all follow-up periods.
- Mitomycin C did not entirely prevent postoperative adhesions.
- No complications were reported in patients who received mitomycin C during the study period.
Conclusions:
- Intraoperative mitomycin C application is a safe adjunctive therapy for strabismus surgery.
- Mitomycin C demonstrates efficacy in reducing postoperative adhesions and improving surgical outcomes in restrictive strabismus.
- Further research may explore optimal concentrations and durations for mitomycin C use.
