[Results of the surgical therapy of exotropia (author's transl)]

An analysis of 113 exotropia operations showed a reduction of the evodeviation for distance to a residual angle of -9 and -12 delta. In 67 cases with unilateral surgery (recession-resection) each additional millimeter beyond two millimeters produced a reduction of angle of about 3 delta for distance, the variance, however, was considerable. The operation of 58 cases with intermittant exotropia improved the manifestation for distance significantly in 71%.
