title: Efficacy of different techniques of superior oblique weakening in the correction of the "A" anisotropia.
abstract: The authors present the results of 118 operations in which five different techniques for superior oblique weakening were employed for the correction of "A" pattern: recession of the tendon, split-lengthening, posterior fiber tenectomy near the scleral insertion, full tenectomy near the scleral insertion and marginal tenotomy (Z lengthening). In all the techniques but one, the marginal tenotomy, a high percentage of correction and a good coefficient of correlation between initial incomitance and obtained correction were found. We propose a new technique of superior oblique weakening, the full tenectomy of the tendon near the scleral insertion, and an easy, safe and effective technique.
