Anisocoria is an uncommon but well-documented early sign of nervous system dysfunction in cases of superficial siderosis. The pupils of both eyes are uneven or unequal in size greater than 0.4mm. It is an indication of optic nerve involvement and often a person will not realize it’s happening until someone notices it and points it out. Anisocoria doesn’t require treatment, does not cause pain or affect vision.
