Introduction: Suturing is a conventional method for pterygium surgery. Owing to its several disadvantages newer techniques like autologous fibrin glue have been introduced as an alternative method of graft attachment. There are few studies which have compared the two techniques.

Aim: To compare suture versus patientís own blood for conjunctival autografting in pterygium surgery.

Materials and Methods: A pilot study was conducted in a Tertiary care hospital from October 2014-June 2016. Seventy-two adult patients with primary progressive pterygium undergoing pterygium surgery with conjunctival autograft were evaluated in this study. Thirty-six patients underwent primary pterygium excision and conjunctival autografting with autologous fibrin glue (glue group) and 36 with 10-0 monofilament polyamide (suture group). Parameters such as mean operating time, presenting complaints like pain, watering, burning and foreign body sensation and graft stability were compared between the two groups on 1st and 5th postoperative days respectively. Categorical data were analysed by Fisher-exact test and continuous data were analysed using Studentís t-test and Wilcoxon signed rank test as applicable.

Results: There was statistically significant difference in the mean operating times between the two groups with results favouring the glue group (p<0.05). The difference in pain (p<0.05 each), watering (p=0.032), burning (p=0.023) and foreign body sensation (p<0.05 each) was found to be statistically significant between the two groups on 1st and 5th postoperative days respectively. The difference in graft stability between the two groups was not statistically significant (p=0.114).

Conclusion: In present study we found that autologous fibrin glue was associated with significantly shorter duration of surgery, lesser postoperative discomfort compared to suturing.
