Abstract
A fundus blood flow metering method includes a series of steps of carrying out alignment of the positional relation with an eye to be examined, carrying out aiming of a blood vessel to be measured, and measuring a velocity of blood flow while tracking the blood vessel so as to track and capture eye movement. After the sequential operation, the direction of incidence of a measuring beam is switched to another direction and the series of steps are again carried out for the same blood vessel, starting from the alignment.
