afferent limb, of pupillary pathway
Section of the visual pathway originating in the rods and cones of the retina and terminating in the brainstem. The fibres follow the visual pathway, decussating in the optic chiasma, and continuing in the optic tracts. The fibres exit the optic tracts before reaching the lateral geniculate body, and project to the brainstem. After synapsing in the brainstem, the fibres then project to the ipsilateral and contralateral Edinger-Westphal nuclei. See pupil light reflex.
