Introduction: Pterygium is defined as a growth of the conjunctiva over the cornea, is a progressive disorder main in advanced ranges to visible impairment, restriction of ocular motility, chronic inflammation and cosmetic concerns. Surgical elimination is the therapy of choice, but recurrence can be a problem. The goal of this study is to examine fibrin glue versus suturing on contrast sensitivity in sufferers present process pterygium excision with free conjunctival autograft. Materials and Methods: In this cross-sectional descriptive-analytical study, 36 patients with pterygium and indication for pterygium surgery had been blanketed in this learn about in two groups of 18 patients. The first group underwent pterygium excision and conjunctivolimbal autograft using suture and the second group underwent pterygium excision and conjunctivolimbal autograft the usage of Fibrin Glue. Patients' contrast sensitivity earlier than and six months after surgical treatment have been measured the usage of a functional acuity contrast test (F.A.C.T) panel beneath the identical prerequisites and by way of one expert person. Results: Among all the variables related to the history of cataract surgery and history of cataract disease, disease characteristics, symptoms and complications of surgery and recurrence of the disease in the subjects were assessed using statistical methods. The foreign body sensation in the agencies of patients undergoing pterygium and conjunctival autograft via suture method used to be significantly greater than Fibrin Glue approach (P = 0.026). Among the variables related to visual status and contrast sensitivity components, logarithm of contrast sensitivity (Log Cs) far B earlier than and after surgery, Log Cs far C after surgery, Log Cs near B before surgery and Log Cs near D before surgery in the groups of sufferers undergoing pterygium and conjunctival autograft by means of suture technique used to be drastically greater than Fibrin Glue technique (P < 0.05) Between the time periods before and 6 months after surgery, the variables of Spherical equivalent refraction, Log Cs far C, Log Cs far D, Log Cs far E, Log Cs near C, Log Cs near D and Log Cs near E in the groups of patients undergoing pterygium and conjunctival autograft by Fibrin Glue method and in the variables of Log Cs far B, Log Cs far E, Log Cs near B, Log Cs near D and Log Cs near E in the groups of sufferers present process pterygium and conjunctival autograft by suture method, there have been no statistically vast modifications (P > 0.05). Conclusion: In phrases of evaluating the difference in contrast sensitivity postoperative between the two agencies of suture and Fibrin Glue, except for the far contrast sensitivity at low spatial frequencies, there was no difference between the two groups. Therefore, we conclude that due to the high cost and the need for surgery of several patients simultaneously when using Fibrin Glue method, the use of the suture method can be equally effective and acceptable.
