Vogt–Koyanagi–Harada disease at the University of Tokyo, in 1911. It was the much later article, published in 1929, that definitively associated Koyanagi with the disease. Harada's 1926 paper is recognized for its comprehensive description of what is now known as Vogt–Koyanagi–Harada disease. Vogt–Koyanagi–Harada disease Vogt–Koyanagi–Harada disease (VKH), also known as Vogt–Koyanagi–Harada syndrome, uveomeningitis syndrome and uveomeningoencephalitic syndrome, is a multisystem disease of presumed autoimmune cause, that affects pigmented tissues, which have melanin. The most significant manifestation is bilateral, diffuse uveitis, which affects the eye. VKH may variably also involve the inner ear with effects on hearing, the skin, and the meninges of

The most useful diagnostic tests detect the bacteria in coughed-up mucus, find "Legionella" antigens in urine samples, or allow comparison of "Legionella" antibody levels in two blood samples taken 3-6 weeks apart. A urine antigen test is simple, quick, and very reliable, but only detects "L. pneumophila" serogroup 1, which accounts for 70% of disease caused by "L. pneumophila",
