In Situ Blood Coagulum versus Sutures for Autograft Fixation after Pterygium Excision

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Pterygium excision often requires autograft fixation to prevent recurrence.
• Traditional suture fixation can lead to patient discomfort and prolonged surgery.

Purpose of the Study:

• To compare the efficacy and patient outcomes of autograft fixation using blood coagulum versus sutures after pterygium excision.

Main Methods:

• A prospective study involving 30 patients with primary pterygium.
• Patients were randomized into two groups: suture fixation (Group 1) and blood coagulum fixation (Group 2).
• Outcomes assessed included graft failure, displacement, recurrence, surgery duration, and patient discomfort.

Main Results:

• Blood coagulum fixation significantly reduced mean surgery duration (14 min vs. 48 min).
• Graft failure/displacement occurred more frequently with blood coagulum (13.3% vs. 6.7%).
• Recurrence rates were similar; suture group reported higher discomfort due to foreign body sensation.

Conclusions:

• Autograft fixation with blood coagulum is an effective alternative to sutures for pterygium excision.
• This technique offers reduced operation time and improved patient comfort.
• While graft stability needs consideration, blood coagulum fixation presents a viable, less invasive option.
