What was discovered

Japanese ophthalmologist Mikito Takayasu described a "wreathlike" appearance of retinal vessels in a patient, which two other physicians at the same conference linked to the absence of a radial pulse: the first described signs of this large-vessel inflammation.

The description was collective, at the 1908 annual meeting of the Japan Ophthalmological Society; it is attributed to Takayasu for presenting the index case.

What it led to

  • Recognition of Takayasu's arteritis as a large-vessel autoimmune disease
  • Diagnostic criteria via angiography
  • Specific immunosuppressive treatments
