[Binocular sensory defects in intermittent divergent strabismus].

Intermittent divergent strabismus represents an entity in terms of motoric characteristics rather than in its sensorial basis. Separate investigations were carried out in two clinics on 156 patients. The results were evaluated together, the authors discussing each case. Only in 27 cases was the condition cured. The main group comprised 78 patients with subnormal binocular vision based on facultative microexotropia and instable/normal correspondence. Basic microexotropia with obligate ARC was found in 51 cases, i.e., more often than expected. Testing the stereo threshold proved to an inadequate criterion for cure.
