[The surgical treatment of vertical strabismus in children].

The paper deals with principles of surgical treatment of vertical squint caused by paresis of muscles of vertical action. The authors consider to be optimal one-stage surgical intervention consisting of enhancing the paretic muscle and weakening the antagonist of the same eye, i. e. the rectus and oblique muscles. The dosage of the surgery was calculated considering the angle of squint. A new method is proposed for calculating the position, on the sclera, of the point of fixation of inferior oblique muscle at its recession. Results of 73 operations are analysed. Orthotropia was achieved in 72.6% of patients. The authors recommend the operation to be widely used in clinical practice.
