Patent ID: 7828437

Claim:
A fundus oculi observation device comprising: an image forming part configured to optically acquire data by imaging through an imaging optical system and form a tomographic image of a fundus oculi of an eye; a storage configured to store optical information representing a state of an ocular optical system of the eye, the optical information including at least one of measured values of corneal curvature, refractive power and axial length of the eye; a calculator configured to calculate a magnification of the ocular optical system, based on the optical information, wherein the calculator is configured to calculate a magnification of the imaging optical system; a measurement position setting part configured to specify and set measurement positions of the fundus oculi; and an analyzer configured to analyze the tomographic image, in order to determine a thickness of a layer of the fundus oculi at the measurement positions set by the measurement position setting part, based on the magnification of the ocular optical system and the magnification of the imaging optical system.
