Double vision diagnosis and treatment is a very large part of this practice specialty. Many other eye care providers refer their double vision patients to us for further evaluation. What is double vision? Essentially it is seeing two images, but sometimes patients may complain only of image blur, headache or the perception of images/objects "running together."  It is also called "diplopia." The diagnosis of eye disease and medical problems associated with double vision is long and difficult, but very important. Certain patients may have to undergo MRI or CT scanning of the brain and orbits to evaluate for important neurologic diseases associated with double vision. Equally important at times are blood work ups, and other specialists which can include neurologists and cardiologists. Occasionally, strokes and tumors of the brain and orbits can result in double vision. Thyroid disease is another clinical problem that can result in double vision. Once diagnosis is made, treatment is directed toward the disease itself. In many cases, the double vision can also be alleviated or eliminated with eye muscle surgery, or with special glasses that contain "prism" a visual tool that neutralizes the double vision that is perceived. When glasses with prism are worn, an individual will be able to see everything as "one image" again. The same can be true of surgery. Depending on the situation, some patients may require glasses with prism, eye muscle surgery, or both. Diagnosis and treatment of a patient with double vision is highly complex and specialized and can be very rewarding for the physicians as well as the patients who present with this problem.
