Third Nerve Palsy:
The third nerve of the brain is responsible for pupillary function, moving the lid up and moving the up, down, and towards our nose. A third nerve palsy presents with a droopy lid, inability to move the eye and sometimes pain. It is associated with high blood pressure, diabetes, and Herpes Zoster. Usually self-limited and improves over time without treatment. If the pupil is involved, it is more ominous and may herald a tumor or aneurysm without pain.
