What Causes Double Vision?

Thyroid Dysfunction

An individual affected by thyroid dysfunction may experience double vision as a result of their condition. The thyroid is a gland in the body responsible for the regulation of numerous processes with the production and administration of hormones. Individuals with a thyroid gland that does not function correctly can experience an associated complication that is called thyroid eye disease. Thyroid eye disease occurs when an individual's immune system abnormally activates receptors in the thyroid gland that result in the excessive production of hormones. The immune system response that causes thyroid issues is also known to adversely affect the individual's eyes. The immune system attacks the healthy fat and muscle tissues behind the individual's eyes. This abnormal response results in inappropriate inflammation behind the eyes that cause the muscles to become stiff. The eyes become swollen, sore, red, and watery. The muscles cannot move the eyes properly, and double vision occurs because the brain is unable to combine both of the eye's representations correctly.
