Diplopia is an eye condition in which a single object appears double. Also expressed as double vision or seeing double, this vision malady drastically impairs visual sharpness.
Binocular and monocular are the two forms of double vision. Binocular diplopia is only present if both of your eyes are open. Thus, closing either eye puts a halt to seeing double.
Binocular double vision is a natural “out of alignment” result whenever the muscles or nerves that control your eyeball’s function are affected by some other health problem. Some causes of this seeing double outcome include:
- brain tumors
- pituitary tumor
- Grave’s disease
- Botox treatment
- diabetes mellitus
- multiple sclerosis
- myasthenia gravis
- traumatic brain injury
- cranial nerve, third nerve palsy
Seeing double in one eye is monocular diplopia. This means your double vision continues whenever you cover the non affected eye.
Monocular double vision is not caused by misalignment, but a problem with the eyeball itself. Monocular diplopia causes of seeing double are usually due to:
And you can have temporary diplopia, which is very often caused by alcohol intoxication or a concussion.
If you experience a sudden, inexplicable onset of diplopia vision, contacting an eye health professional should be your next call.
Treatment for seeing double starts by determining its cause. Treating the underlying health condition often corrects many binocular double vision situations.
As for other seeing double circumstances, vision correction treatment may involve:
- eye surgery
- vision therapy
Over time, binocular diplopia vision may appear to go away. It’s because your brain eventually suppresses one of the images to avoid seeing double.
