How does diplopia occur?
Nerve or muscle damage in the eye might cause double vision. Each eye creates its own image of the environment. The brain combines the representations from each eye and perceives them as one clear picture. Damage to the muscles that move the eyes or the nerves that control eye movement can create a double image.
How do you test for diplopia?
By asking you to follow his or her finger as it moves up and down and to the far right and left, the doctor can determine if there is any eye muscle weakness. If the diplopia is monocular, the cause may be within the eye, so a doctor may use an instrument called a slit lamp to examine the eye under magnification.
When should you see a doctor for double vision?
