Double vision, or diplopia, can be a sign of serious medical conditions such as weak eye muscles, nerve damage, or brain problems. Treatment may include medication or surgery, and routine eye exams can detect potential problems. Brain injuries and diseases such as diabetes and multiple sclerosis can also cause double vision.
Double vision, known to the medical community as diplopia, can be very annoying and should always be taken seriously. While most cases are relatively mild, double vision can be a sign of something serious. Common causes of double vision include weak eye muscles, nerve damage, or in severe cases double vision can be caused by problems with the brain. Double vision may be the only symptom or it may be accompanied by other symptoms such as eye pain, nausea, or headaches. Treatment may include the use of medications or surgery, depending on the exact causes of the double vision.
Problems with the cornea, the clear part of the eye that covers the iris and pupil, can be one possible cause of double vision. This problem can develop due to an infection or as a complication of eye surgery. Opacity in the eye, known as a cataract, can also be among the potential causes of double vision. A routine visit to an eye doctor can often detect these problems before they cause a significant impact on your ability to see clearly.
Weak eye muscles are another potential cause of double vision. This muscle weakness can occur due to underlying medical conditions such as myasthenia gravis or Grave’s disease. In these situations, medications may be able to help correct double vision, although surgery is often needed to repair weakened muscles in order to prevent further damage.
Damage to the nerves that feed the eyes can also be a cause of double vision. Diseases such as diabetes or multiple sclerosis are known to affect the nerves and can cause many vision problems, including the development of double vision. While medications and surgery may be appropriate choices in some cases, these diseases can lead to permanent eye damage and some degree of vision loss in addition to double vision.
Among the more serious causes of double vision are various problems with the brain itself. A person who suffers from frequent migraines may develop double vision as a result of the migraine. Those who have suffered a stroke or suffered a direct injury to the brain are prone to developing double vision. If you have a traumatic brain injury that causes permanent brain damage, there may not always be a cure for symptoms such as double vision.
