Abstract:
This cycloduction measurement device is provided with a blood vessel position recognition unit and a first angle calculation unit. The blood vessel position recognition unit recognizes the position of a blood vessel in a sclera region in an eye image, and acquires information pertaining to the position of the blood vessel. The first angle calculation unit calculates the angle of cycloduction on the basis of the first information pertaining to the position of a predetermined blood vessel acquired by the blood vessel position recognition unit during actual measurement of cycloduction, and a second information pertaining to the position of the predetermined blood vessel while in a reference state.
