The brain receives different images when the two eyes do not focus together. Two images are seen, instead of one. This is called diplopia or double vision. Double vision can occur when the muscles surrounding the eyes do not work in unison.
A wide range of health problems can produce double vision and include: - diabetes
- myasthenia gravis
- early cataract
- brain tumour
- retinal surgery
- poorly fitted contact lenses
- multiple sclerosis
- Graves' disease
- brain injury
- facial fractures and
- alcohol intoxication
In these kinds of health problems, nerves that carry impulses between the brain and the eye muscles, or the nerves of the eye muscles themselves, do not work correctly. Due to the wide range of disorders that can cause this symptom, anyone with double vision should seek medical care. Double vision may be resolved by treatment of the underlying health problem. If not, prescriptive eyeglasses may help. Muscle misalignment problems can be surgically corrected. Article #4512 Copyright (c) 2002 McKesson. All Rights Reserved. |
