Summary
Trabeculectomy surgery, a glaucoma treatment, showed a 90% success rate using either limbus-based or fornix-based conjunctival flaps. Limbus-based flaps offered slightly better intraocular pressure control post-surgery.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Glaucoma is a leading cause of irreversible blindness worldwide.
- Trabeculectomy remains a primary surgical intervention for managing intraocular pressure in glaucoma patients.
- Conjunctival flap technique is a critical component influencing surgical outcomes.
Purpose of the Study:
- To compare the efficacy and safety of limbus-based versus fornix-based conjunctival flaps in trabeculectomy.
- To evaluate the impact of flap technique on postoperative intraocular pressure control and surgical success rates.
Main Methods:
- A prospective study involving 40 consecutive trabeculectomies performed by a single surgeon.
- Eyes were randomized into two groups: 20 with limbus-based flaps and 20 with fornix-based flaps.
- Outcomes assessed included surgical success rate and intraocular pressure measurements.
Main Results:
- Both limbus-based and fornix-based flaps achieved a high success rate of 90%.
- Eyes with limbus-based flaps demonstrated slightly superior postoperative intraocular pressure reduction.
- No significant difference in major complications was noted between the two techniques.
Conclusions:
- Both limbus-based and fornix-based conjunctival flaps are effective surgical techniques for trabeculectomy.
- Limbus-based flaps may offer a marginal advantage in achieving lower intraocular pressure postoperatively.
- The choice of flap technique can be tailored based on surgeon preference and specific patient factors.
