Objective: To evaluate the surgical technique for excision of primary pterygium with fibrin glue, as the symptoms and epidemiological data. Methods: Clinical prospective non-controlled and randomized study with 30 patients of the Hospital Universitario Lauro Wanderley, consistent with the term informed consent, approved by the Ethics in Research. The surgeries were evaluated at 1, 7 and 21 postoperatively (PO). Results: Of the 30 operated patients, 16 (53,3%) were female, aged 21-67 years (42.2). As for the degrees of pterygium (1-3): grau 1-10 (33,3%), grade 2-16 (33,3%) and grade 3-10 (33,3%), 16 (53,3%) in the right eye and 16 (44.4%) in the left eye. 56,7% of patients had intense sun exposure during their lifetime and cases in the family. In the trans-operative period, there were complaints of pain (43,3%) and foreign body sensation (46,7%). Surgical time ranged from 11 to 32 minutes (17.7). The complaints in the first, seventh and 21 PO, respectively, were pain (60%, 26,6% e 6,66%), redness (93,3%, 66,6% e 36,6%), foreign body sensation (53,3%, 46,6% e 20%), epiphora (83,3%, 43,3% e 6,66%), discharge (33,3%, 36,6% e 6,66%), burning (53,3%, 36,6% e 16,6%) and dry eye (6,66%, 26,6% e 23,3%). 43,3% reported being very satisfied with the surgery and 63.8% considered excellent aesthetic appearance. 3 (10%) patients did not attend the 7 DPO and 5(16,6%), at 21 DPO. There was no graft loss in the cases studied. Conclusion: Autologous conjunctiva is currently the most effective alternative for the treatment of pterygium. Associated with the use of fibrin adhesive, which is composed of fibrinogen and thrombin and has the advantage of being totally absorbable, has advantages, among them a reduction in surgical time. In this study, corroborating recent studies, the mean operative time was 19.05 (+/- 6.1) minutes and there was a high incidence of family pterygium patients and UV exposure. Complaints of dry eye increased progressively after surgery, revealing a possible change in blink rate. Rarely addressed in the literature, the symptoms assessed in this study, showed that complaints Intraoperative mild and marked the first POD, regressed from the 7th POD, justifying the higher patient satisfaction and excellent aesthetics that using this technique.
