ABSTRACT

Introduction: The objective of the present study was to determine whether resection of Tenon capsule produces a smaller inflammatory response after strabismus surgery. Matherial and methods: A prospective, comparative, and longitudinal study was performed. Patients with diagnosis of esotropia and candidates for surgery were included. After a complete ophthalmologic evaluation, a symmetrical and bilateral surgery in both internal rectus muscles was carried out. At the end of surgery in one eye, the Tenon capsule was resected in the study group and the control group consisted of patients without resection of the remaining eye. During the postoperative period, antibiotics and topical steroids were administered for 2 weeks. Inflammatory response was evaluated in 110 eyes divided into two groups: group I with resection of Tenon capsule and group II, without resection. The following parameters were analyzed: tearing; hyperemia, and subconjuntival edema; these were evaluated on the day following surgery, at 1 week, at 2 weeks, at 1 month after surgery. For statistic analysis, Mann-Whitney test was used with significance level of 0.05. Results: Fifty-five patients were included, 29 females and 26 males from 2-21 years of age, average age of 6.5 years. One hundred ten eyes were evaluated, difference was found in tearing between the groups at all moments of evaluation. Conjuntival hyperemia was greater in group II during the entire follow-up, this being a meaningful difference. Subconjuntival edema did not show significant changes at the beginning and at end of evaluation; however, greater edema was observed in the group II in evaluations done between days 8 and 15. With these study results, we can conclude that a smaller inflammatory response is present after strabismus surgery if carried out with resection of Tenon capsule at end of surgical procedure.
