Surgical procedure for restoration of the physiological alignment of the eyes following muscular dysfunction

Eight adult patients suffering from bilateral or unilateral N VI paralysis of more than one year's standing, and from rupture of the inferior rectus muscle due to accident underwent transposition of the muscle venter, a method which has been practiced now for five years. In all these patients the starting point of eyeball movement was shifted either outward or downward with the result that the primary position of the yeses could be used for either full or intermittent binocular vision. Where the patient had monocular vision either unilateral or alternating, at least spatial orientation was improved, as a result of the restored physiological alignment of the visual axes with the sagittal plane of the body.
