Adesivo biológico de fibrina na mioescleropexia posterior em coelhos: estudo experimental

PURPOSES: 1. To evaluate the adhesion capacity of the fibrin biological adhesive in surgery of posterior fixation of the superior rectus muscle, when it is used for the reduction of the arc of contact. 2. To compare the reduction of the superior rectus muscle's action of eyes in which the biolo...

Sumario:PURPOSES: 1. To evaluate the adhesion capacity of the fibrin biological adhesive in surgery of posterior fixation of the superior rectus muscle, when it is used for the reduction of the arc of contact. 2. To compare the reduction of the superior rectus muscle's action of eyes in which the biological adhesive has been used with those used as a control group. METHODS: The sample consisted of 30 animals, 60 eyes. One of the eyes of each animal was treated with biological adhesive (30 eyes), while the other was used as a control (30 eyes). All animals were sacrificed on the 60th postoperative day. Muscle reduction was analyzed and the sizes of the adherences produced at surgery and after 60 days were measured. RESULTS: The fibrin clot was produced immediately after applying the biological adhesive and at the end of few seconds all muscle fibers were adhered to the sclera. All muscles treated with biological adhesive showed reduction in motor function on the 60th postoperative day when compared with the control group. The sizes of the initially produced adherence compared with those after 60 days was reduced 28.48%. There was an ascending and positive but weak correlation (r=0.367204). There must exist other variables affecting adherence reduction. There was no significant inflammatory reaction or any other complication related to the surgery. CONCLUSIONS: The clinical results of motor function demonstrated that the biological adhesive of fibrin produced muscle-scleral adhesion, reducing the arc of contact of the superior rectus muscle in rabbits.
