Safety and efficacy of fibrin glue versus infinity suture in SICS with extended scleral flap.

PURPOSE: To study the safety and efficacy of biologic fibrin glue (FG) in comparison with infinity suture in SICS with compromised scleral flap.

METHODS

A retrospective comparative study of patients who were treated with FG (Group A) with 10-0 nylon (Group B) as sealing agent for intraoperative compromised tunnels in SICS. Parameters noted were postoperative inflammation, wound integrity, anterior chamber (AC) depth, intraocular pressure (IOP), and surgically induced astigmatism (SIA) at postoperative day 1, 4 weeks, 6 weeks, and 6 months, respectively. Epi Info 7 software and SIA calculator, Version 2.1 were used to analyze the result.

RESULTS

We reviewed the two groups of 18 patients each and noted that there was no statistically significant difference in postoperative inflammation (P > 0.05), AC depth (P > 0.05), and IOP (P > 0.05) between both groups at each postoperative visit. One patient in Group A showed postoperative shallow AC and subconjunctival bleb. Exposed sutures causing foreign body sensation had to be removed in five patients in Group B. At the end of 6-month postoperative period, no statistically significant difference was found in SIA (P = 0.92) between the two groups.

CONCLUSION

Biologic FG can be safely used in securing the compromised scleral incisions in SICS. It also avoids suture-related complications.
