Third Cranial Nerve Compression Mononeuropathy

Compression mononeuropathy of the third cranial nerve is a disorder of the nerve that controls much of the movement of the eye and eyelid, produced when a nearby structure puts pressure on it.

Frequent symptoms: Drooping eyelid, double vision, difficulty moving the eye in certain directions, and, in some cases, changes in the size of the pupil.

When to see a doctor? The sudden appearance of double vision or a drooping eyelid, especially with pain, requires a prompt evaluation.

Which specialist evaluates it? Although the general practitioner can guide the first contact, its workup falls to neurology and ophthalmology. With these vision changes, it is important to have them reviewed by a professional to determine the cause.
