[The mechanism of inhibition of binocular vision in convergent strabismus (author's transl)].

The mechanism of inhibition of binocular vision (at a cortical level in the Pavlovian sense) in convergent strabismus is described. The study concerns both those patients whith no amblyopia and those whose amblyopia has been cured. Part one of the article describe the clinical characteristics of this cortical inhibition as shown by the polarised light stereoscopic projector. Some basic concepts with this therapeutic application are described in part two. In this paper the author suggests a relationships between the severity of inhibition of binocularity and the degree of disturbance in spatial localisation. The greater the inhibition at a cortical level, the more disturbed is the localisation of objects in space in binocular vision. The treatment of inhibition must include precipitating causes that is to say the disturbed binocular relationships of abnormal retinal correspondence and is complete when cortical inhibition and abnormal retinal correspondence has been completely rectified. On the other hand there are occasions when it is not possible to eliminate abnormal retinal correspondence, this is especially true in older patients, and under this circumstances, it is better to accept inhibition of binocular function than to have diplopia.
