Single Injection of Bupivacaine for Correction of Strabismus

To evaluate the effectiveness of a single injection of Bupivacaine (BPX) application for correction of eso/exodeviations this study has been performed.A retrospective review of 30 patients with eso/exodeviations less than 20 prism diopters (PD). Preoperative deviations were recorded in PD, using the alternate prism cover test. Postoperative angles at 1 and 3 months were measured in the same manner.The mean angle of deviation for near in all patients reduced significantly by 3.1 PD and 2.1 PD at 1 and 3 months. The mean angle of deviation for distance in all patients also decreased significantly by 2.3 PD and 1.9 PD at 1 and 3 months.As conclusions, single injection of BPX in a heterogeneous group of patients with horizontal strabismus caused a mild improvement in a qualitative success rate of 37%.
