Provided is a method for an ophthalmic examination by an ophthalmic examination system including an ophthalmic examination apparatus and an examiner-side apparatus that is connected to the ophthalmic examination apparatus by a network and is provided with an interface for input/output, the method including: a transmission step of transmitting an error signal from the ophthalmic examination apparatus to the examiner-side apparatus upon occurrence of an error in the ophthalmic examination apparatus; a selection step of, upon the examiner-side apparatus receiving the error signal, notifying an examiner of the occurrence of the error via the interface and also accepting selection input for selecting any of a plurality of predetermined handling methods of the error; a response step of the examiner-side apparatus transmitting a response signal to the ophthalmic examination apparatus on the basis of the selection input; and a notification step of, upon the ophthalmic examination apparatus receiving the response signal, notifying the examinee of guidance information on the action against the error on the basis of the response signal via an output device.

Method for ophthalmic examination and remote examination program

An eye refractive power measurement apparatus includes: a measuring optical system for projecting measurement light onto a fundus of an examinee's eye, and causing a two-dimensional imaging device to capture the measurement light to be reflected from the fundus as a plurality of target pattern images at different distances from a measurement optical axis; a light deflecting member arranged at a position out of a conjugate position with a pupil of the examinee's eye on an optical path of the measuring optical system; a rotor for rotating the light deflecting member about an optical axis of the measuring optical system to allow a plurality of pattern light beams to be eccentrically rotated on the pupil; and a calculator for measuring an eye refractive power of the examinee's eye based on a target pattern image to be captured by the two-dimensional imaging device.

Eye refractive power measurement apparatus

An eye refractive power measurement apparatus measures both eye refractive powers in cases where a pupil is small and large in diameter with ease. This apparatus includes: a measuring optical system causing an imaging device to capture a ring-shaped image based on measurement light reflected from a fundus of an examinee's eye; a light deflecting member arranged at a position, which is not conjugated with a pupil of the examinee's eye, on an optical path of the measuring optical system; a rotor causing the light deflecting member to rotate about an optical axis of the measuring optical system; and an eccentricity amount changer changing an amount of eccentricity of the measurement light, which is rotated eccentrically on a surface of the pupil, with respect to a center of the pupil, in order to change a region, where the measurement light passes, on the surface of the pupil.
