Pierce Maxwell · Answer 1

Right oculomotor nerve

Explanation:

The oculomotor nerve is the third cranial nerve.

It contains fibers that supplies nerves to the extrinsic eye muscles which enables movements and pupillary response such as eye movement, response to light and raising of the eyelids.

It enters the obit via the superior orbital fissure.

Therefore, when a patient's right eye has dilated pupils, unresponsive to light and the eyelids drops. The lesion is on the oculomotor nerve.
