Pterygium is a fibrovascular proliferation of subconjunctival tissue that crosses the limbus and develops on the cornea. It's a chronic condition brought on by a degenerative disease of the ocular surface. The eyes are irritated, the tear film is disrupted, and the patient's eyesight worsens. The purpose of this study was to evaluate the efficacy of sutures vs fibrin glue adhesive for securing the conjunctival autograft during pterygium surgery. Methods: There were a total of, participants in this prospective comparison research. The participants, all of whom had primary pterygium of at least one eye, were randomly assigned to one of two groups (A and B), each of which had 25 people. The results showed that the two groups' best corrected visual acuity (BCVA) did not vary significantly before and after surgery. The research found that the fibrin glue group required significantly less time (264.5 minutes) than the suture group. (38+ 2,2). Within the suture group, graft retraction is the most frequent consequence. After a mean follow-up time of 7.2 months, the recurrence rate in this trial was 8% in the glue group and 13% in the suture group. fibrin glue is superior to 8/0 vicryl sutures for attaching the free conjunctival autograft during pterygium surgery due to its ability to reduce operating time, postoperative pain, and recurrence rate.
