Yoshizo Koyanagi

Yoshizo Koyanagi (小柳 美三, Koyanagi Yoshizō, December 10, 1880 – 1954) was a Japanese ophthalmologist who is recognized for his description of what is now known as Vogt–Koyanagi–Harada disease (VKH).[1][2][3][4]

Koyanagi received his medical education at the Imperial University in Kyoto. He graduated in 1908 and studied ophthalmology under Ikujiro Asayama.[3] He held a variety of positions, eventually retiring in 1942.[5] In recognition of his contributions, the government posthumously conferred on him the Order of the Sacred Treasure, Second Class.[5]

His first description of what is now known as Vogt–Koyanagi–Harada disease was in 1914.[1] This was preceded by Jujiro Komoto, Professor of Ophthalmology at the University of Tokyo, in 1911.[1] However, Koyanagi became definitively associated with VKH in 1929, when he published an article in which he typified the time course of the disease as it went through its sequential phases.[1][6][7]
