What Causes Double Vision?

Aneurysm

A brain aneurysm can cause an affected individual to experience double vision as a result of their condition. When a weakened region of the arterial wall fills with blood and bulges in the brain, it is called a brain aneurysm. An aneurysm can be the result of trauma or another underlying condition. An aneurysm in the brain can remain unruptured for an extended period, or it can rupture. A ruptured aneurysm is a life-threatening and urgent emergency. An unruptured aneurysm is a projection of tissue in a place where it does not belong. Aneurysms can press on any surrounding organs or structures just like a projection of any other tissue in a place where it does not belong. When a brain aneurysm occurs in the area near an individual's eye, it can cause some of the nerves connecting the eye to the brain to become compressed. The compressed nerves are unable to transmit the electrical impulses that feed the image from the eyes to the brain. This disruption in the nerve pathway can cause a patient to have blurry and or double vision.
