Vogt-Koyanagi-Harada syndrome is a condition that involves chronic inflammation of melanocytes, which are specialized cells that produce a pigment called melanin.  Melanin is the substance that gives skin, hair, and eyes their color.  Melanin is also found in the retina, where it plays a role in normal vision.  Individuals with Vogt-Koyanagi-Harada syndrome usually develop vision and hearing disturbances first, followed by signs of skin problems.  Research suggests this condition is an autoimmune disease.  Vogt-Koyanagi-Harada syndrome is more common in individuals with darker skin pigmentation including Asian, Middle Eastern, Hispanic, and Native American populations.[1][2]
