[The clinical picture and treatment of dissociated vertical strabismus].

The paper describes clinical picture of a special form of oculomotor pathology--dissociated vertical squint characterized by vertical deviation into different directions, a different value of vertical deviation in abduction-adduction, a forced position of the head, infrequently--pseudoptosis of the upper lid of the downwards deviated eye, normal or slightly reduced visual acuity. The approach of surgical treatment is described. A stage-by-stage surgical treatment in 125 patients resulted into elimination of deviation in 67.2% of cases, restoration of normal binocular vision at different distances in 23.2%, binocular vision for near in 11.2% of patients. Orthoptic-diploptic treatment is shown to be expedient in patients with periodically small (to 8 degrees) angles of dissociated vertical squint, leading to restoration of binocular vision in 54.4% of patients.
