What are the symptoms of anisocoria?

Anisocoria can be accompanied by serious symptoms. Go to the emergency room if one pupil is bigger than the other and you experience any of the following:

• Eye pain.
• Loss of vision.
• Blurry vision.
• Double vision (diplopia).
• Light sensitivity.

You might have symptoms outside your eyes too, including:

• Fever.
• Headaches.
• Nausea or vomiting.
• Neck pain or stiffness.

Depending on what’s causing the anisocoria, you might have no symptoms. If that’s the case, you still need the change in your eyes examined by a provider. You might also still need imaging tests to rule out one of the causes of anisocoria that can be life threatening.
