Ans. is 'b' i.e., Left eye complete blindness with loss of ipsilateral direct and contralateral consensual light reflex * Lesions of optic nerve causes:-i) Complete visual field loss of the ipsilateral eye (blindness);ii) Abolition of ipsilateral direct and contralateral consensual light reflex;iii) Near (convergence/accommodative) reflex is intact as optic nerve is not involved in near reflex.
Left eye complete blindness with loss of contralateral direct and ipsilateral consensual light reflex
Left eye complete blindness with loss of ipsilateral direct and contralateral consensual light reflex
