Double Vision Symptoms
Introduction
Double vision, medically known as diplopia, is an eye condition where a person sees two images of a single object. It is caused due to an issue with one or more eye structures.
What is Double Vision?
Each eye has a separate nerve that carries a picture of the object as seen by that eye to the brain. Double vision occurs if each eye sends information to both hemispheres of the brain and each side of the brain receives two images.
Types
There are two types of double vision:
- Monocular diplopia is present when a person uses only one eye at a time, appearing as a shadow. It is less severe and more common.
- Binocular diplopia occurs when both eyes are simultaneously open and disappears if you cover one eye. It has more serious underlying conditions.
Symptoms
The symptoms associated with double vision include:
- Headache
- Nausea
- Dizziness
- blurred vision
- Pain
What are the causes of double vision?
Monocular diplopia is commonly caused by cataracts, astigmatism, dry eye syndrome, iris (the colored part of your eye) abnormalities, or ill-fitting glasses or contact lenses.
Binocular diplopia is caused by misaligned eyes, cranial nerve issues, brain aneurysms, or stroke. Other causes of double vision are myasthenia gravis, proptosis, vertigo, keratoconus, and diabetes.
Celebrex (inflammation), Tylenol (pain relief), Adipex (for obesity), Mevacor (elevated cholesterol), Lamictal (seizures), and Zantac (ulcers) can also induce double vision.
When should you consult a doctor if you have double vision?
Consult a doctor as soon as you notice any changes in your vision. Get your eyes examined regularly if you wear glasses or contact lenses. Seek medical advice to get rid of the condition.
