(Example: When the left eye is stimulated by light, left pupil does not constrict, because the efferent signals cannot pass from midbrain to the left pupillary sphincter.) The contralateral consensual reflex is intact. (Example: When the left eye is stimulated by light, the right pupil constricts, because the afferent limb on the left and the efferent limb on the right are both intact ) The contralateral direct reflex is intact.
