What is the definition of Vogt-Koyanagi-Harada Disease?
Vogt-Koyanagi-Harada disease (VKH disease) affects the eyes, ears, nervous system, and skin. The symptoms of VKH occur in different phases. The early symptoms include headaches, eye pain, and dizziness. These are followed by hearing loss and inflammation of the eye (panuveitis). Later symptoms include development of white patches of skin and hair (vitiligo), hair loss (alopecia), cataracts, and glaucoma. The exact cause of VKH disease is unknown, but the symptoms are thought to be due to an abnormal response of the immune system to a viral infection. Genetic factors may be involved. Diagnosis of VKH disease is based on the symptoms, clinical exam, and imaging studies. Other more common diseases may need to excluded before a diagnosis of VKH disease is made. VKH disease is treated with corticosteroids and other medications.

How is Vogt-Koyanagi-Harada Disease diagnosed?
Vogt-Koyanagi-Harada (VKH) disease is diagnosed based on the symptoms, clinical exam, eye exam, and imaging studies. In addition, other more common conditions may need to be excluded before VKH disease can be diagnosed. A set of standard signs and symptoms have been published to help guide the diagnosis of VKH disease.
