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%.
