Patent ID: 8915593

Claim:
An ophthalmologic apparatus comprising: an optical measurement system that radiates measurement light to an eye to be examined, a drive unit that moves the optical measurement system relative to the eye, an imaging unit that takes a cross sectional image of the eye by using reflected light of the measurement light from the eye, a detecting unit that detects a position of a corneal top of the eye, and a controller that controls the drive unit and the imaging unit, wherein when the drive unit positions the optical measurement system relative to the eye, the controller obtains a two-dimensional cross sectional image by the imaging device, one axis of the two-dimensional cross sectional image extending in a vertical direction of the eye, and wherein the drive unit positions the optical measurement system such that the position of the corneal top detected by the detecting unit is positioned at a reference position preset in the two-dimensional cross sectional image obtained by the imaging unit, and the controller determines whether the eye is in an examinable state or not based on a specific area preset in the two-dimensional cross sectional image, the specific area having a predetermined range in the vertical direction and is a predetermined distance away from the reference position in the vertical direction.
