摘要: Disclosed is an ophthalomological diagnosis method and apparatus in which a blood vessel the eye fundus illuminated with laser beam of predetermined spot whose diameter substantially equal to or smaller than that order produce speckle pattern produced by light scattered from fundus. Boiling motion thus then detected through multiple detection aperture comprised plurality small apertures as fluctuation total amount passing obtain signal evaluated measure velocity flowing concerned. This arrangement makes it possible detect without any averaging process increase intensity detected, enabling advantageous successful measurement flow state
