Double Vision and Severe Headache in Adults
By: Jeffrey Colburn, MD
A new symptom of double vision, particularly in adults, may be sign of a neurologic abnormality and should be evaluated by an eye doctor for signs of anything serious. The most immediately dangerous potential cause in an adult is an aneurysm causing a Cranial Nerve 3 Palsy. Signs of this include brand-new double vision, with one eye that doesn’t track toward the nose well, often with a severe headache, and possibly with a droopy upper eyelid or an enlarged pupil. This is a possibly urgent and life-threatening situation and you should go directly to the Emergency Room as soon as possible for an emergency aneurysm evaluation. Most other double vision situations will be evaluated in the eye doctor’s office first.
