Summary
Releasable sutures in trabeculectomy significantly reduce short-term complications like hypotony and shallow anterior chamber. They also improve long-term intraocular pressure control and bleb scores compared to conventional sutures.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Glaucoma Treatment
Background:
- Trabeculectomy is a common surgical procedure for glaucoma.
- Scleral flap suturing technique impacts surgical outcomes.
- Conventional interrupted sutures may lead to complications.
Purpose of the Study:
- To compare releasable sutures versus conventional interrupted sutures for scleral flap in trabeculectomy.
- To evaluate short-term and long-term efficacy of both suturing methods.
Main Methods:
- Prospective randomized study at a university-affiliated eye hospital.
- Thirty patients with uncontrolled primary glaucoma were included.
- Fifteen patients received releasable sutures, and fifteen received permanent interrupted sutures.
Main Results:
- Releasable sutures group showed significantly lower incidence of short-term hypotony (20% vs 53%) and shallow anterior chamber (7% vs 33%).
- Long-term intraocular pressure was significantly lower with releasable sutures (15.0 mmHg vs 16.9 mmHg).
- Success rate was 100% with releasable sutures versus 80% with conventional sutures; bleb scores were higher with releasable sutures.
Conclusions:
- Releasable sutures are effective in maximizing long-term bleb score and lowering intraocular pressure.
- This technique minimizes short-term complications of trabeculectomy without additional cost or instrumentation.
- Releasable sutures offer an improved safety and efficacy profile for trabeculectomy.
