Living with Congenital oculomotor nerve palsy

A rare eye condition present from birth that causes a droopy eyelid and trouble moving the eye, usually on one side.

Understanding Congenital oculomotor nerve palsy

Congenital oculomotor nerve palsy is a rare eye condition present from birth that involves one of the nerves that move the eye.

It causes a partly or fully drooping eyelid (ptosis) and weakness of eye movements (ophthalmoplegia). The eye may have trouble moving up, down, or inward, which can cause crossed eyes (strabismus) and lazy eye (amblyopia). The pupil can be widened. It is typically on one side only.
