described in 1908 by Japanese ophthalmologist Mikito Takayasu at the Annual Meeting of the Japan Ophthalmology Society. Takayasu described a peculiar "wreathlike" appearance of the blood vessels in the back of the eye (retina). Two Japanese physicians at the same meeting (Drs. Onishi and Kagoshima) reported similar eye findings in individuals whose wrist pulses were absent.
