PURPOSE: An ophthalmologic apparatus and a blood flux calculation method are provided to measure blood flux in a constant measurement range regardless of a scanning direction. CONSTITUTION: A light beam emitted from a light source(101) is divided into a reference light(105) and a measurement light(106) by an opto-coupler(131). An SLO(Scanning Laser Ophthalmoscope) device(109) leads the measurement light to an eye to be measured(107) through a single mode fiber(130-4), first and second spatial modulators(159-1,159-2), an XY scanner(119), and a plurality of spherical mirrors(160-1-160-9). The measurement beam is moved as a feedback beam(108) to a detector(138) that changes the intensity of the feedback beam into a voltage signal. The detector forms a plane image of the eye to be measured based on the voltage signal and calculates blood flux based on the plane image. |
