What causes anisocoria?

Anisocoria can be caused by a lot of conditions in your body, injuries, traumas and even some medicines.

Some of the most common causes include:

• Migraine headaches.
• Glaucoma.
• Seizures.
• Eyedrops, scopolamine skin patches and some other medicines.
• Recreational drugs like cocaine.

Anisocoria can also be caused by serious, life-threatening conditions, including:

• Brain aneurysms.
• Strokes.
• Brain tumors.
• Infections like meningitis.
• Injuries and trauma to your head, eyes or the arteries that supply blood to them.

Your healthcare provider will classify your anisocoria as either pathological (caused by a disease) or physiological (caused by something malfunctioning inside your body).

This distinction isn’t as important as getting your symptoms evaluated right away. No matter what’s causing your pupils to be irregularly sized, you should see your provider as soon as possible.
