[New viewpoints on the pathogenesis and the treatment of strabismus. First part: pathogenesis of strabismus (author's transl)].
In 1962 the anteroposition of the inferior oblique muscle has been introduced. This surgery enlarges the angle between the muscle and the visual axis favouring the torsional action at the cost of the vertical one. The results of 554 cases with a postoperative follow-up of at least ten years are analysed. The spontaneous recovery of binocular vision and the disappearance of the accommodative component suggest that a sagittalization of the oblique muscles might be an important cause of strabismus. The evolution of the suppression scotoma demonstrates that the position of the eyes depends on the optomotor balance between the nasal and temporal retinal halves. A new concept of the pathogenesis of squint is presented. The sagittalization of the oblique muscles and the hemiretinal suppression are considered to be the keys by means of which the problem of strabismus could be solved.
