Fornix-based Trabeculectomy With Mitomycin C Using the Horizontal Conjunctival Suture Technique

Area of Science:

• Ophthalmology
• Surgical Techniques
• Glaucoma Treatment

Background:

• Glaucoma management often requires surgical intervention to reduce intraocular pressure.
• Trabeculectomy is a common glaucoma surgery, with variations in technique influencing outcomes.
• Mitomycin C is frequently used to enhance trabeculectomy success rates.

Purpose of the Study:

• To evaluate the safety, efficacy, and bleb morphology of fornix-based trabeculectomy using mitomycin C and a horizontal suture technique.
• To assess the long-term outcomes and complication rates associated with this specific surgical approach.

Main Methods:

• A retrospective case series included 79 eyes from 69 patients who underwent fornix-based trabeculectomy with mitomycin C.
• Conjunctival closure was performed using a horizontal suture technique with 10-0 nylon.
• Key outcome measures included bleb morphology, surgical success, and postoperative complications.

Main Results:

• At a mean follow-up of 25.5 months, 82.3% of eyes exhibited diffuse blebs.
• Complete or qualified success was achieved in 87.4% of patients.
• Complications such as corneal encroachment (3.8%) and bleb leakage (8.8%) were observed, with overfiltration in 2.5% of eyes.

Conclusions:

• The horizontal suture technique is a simple and time-efficient method for fornix-based trabeculectomy.
• This technique results in excellent bleb morphology and a low rate of long-term complications.
• Fornix-based trabeculectomy with mitomycin C and horizontal sutures offers a safe and effective glaucoma treatment option.
