摘要： An ophthalmologic apparatus comprises an optical measurement system that radiates measurement light to an eye to be examined, an imaging unit that takes a cross sectional image of the eye by using reflected light of the measurement light from the eye, and a controller that controls the optical measurement system and the imaging unit. When the optical measurement system is positioned at a measurement position, the controller obtains a two-dimensional cross sectional image by the imaging device. One axis of the two-dimensional cross sectional image extends in a vertical direction of the eye, and another axis of the two-dimensional cross sectional image extends in a depth direction of the eye. The controller determines whether the eye is in an examinable state or not based on the two-dimensional cross sectional image.
