Double Vision Services in Fort Myers, FL


Double Vision (Diplopia)

Over the past several years, West Coast Eye Care has treated an increased number of patients for diplopia, commonly called double vision. Double vision can occur at any age and usually occurs because of the eyes being misaligned.
It is not a normal state and can be a sign of serious eye or neurological disease. Each eye has six different muscles responsible for moving it, which means the brain must control twelve muscles simultaneously through a pathway of nerve connections that course throughout the central nervous system.

Causes of Double Vision

Eye muscle control is complex and vulnerable to many disease conditions. Three different cranial nerves supply the eye muscles of each eye and any condition affecting them such as strokes, injuries, or brain tumors can cause double vision. Diabetes frequently causes diplopia when the diabetic process is responsible for a small stroke to one of the cranial nerves. Thyroid disease and myasthenia gravis can affect the eye muscles also causing double vision.
A person experiences double vision usually after an injury or infection such as a viral illness. Their brain turns off or suppresses the information from a misaligned eye so that double vision does not occur.

Symptoms of Double Vision

A person with double vision sees two separate images—sometimes very close like a ghost image and some so far apart that the second image may be ignored. Images may be horizontally or vertically separated or both. Covering one eye usually eliminates diplopia.
The condition and severity of the double vision may vary based on where the person is looking. For instance, images may appear closer together when looking to the right and further apart when looking to the left. Adopting a particular head position may make the images single again.

Treatment of Double Vision

Under certain circumstances, the underlying cause can improve spontaneously and double vision can regress without treatment. If not, diplopia may be treated by applying special optical devices called prisms to the patient's glasses.
This is usually done through a comprehensive eye muscle evaluation performed by an orthoptist or eye muscle technician. If diplopia persists after medical or orthoptic treatment, muscle surgery may be needed. Eye muscle surgery adjusts the muscles to straighten the eyes, which will eliminate double vision.
