<prompt> What will be the consequence if the left optic nerve is cut-Left eye complete blindness with loss of contralateral direct and ipsilateral consensual light reflexLeft eye complete blindness with loss of ipsilateral direct and contralateral consensual light reflexLeft eye complete blindness with no effect on light reflexBitemporal hemianopia  <response>: 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 convergenceaccommodative reflex is intact as optic nerve is not involved in near reflex.
