摘要： A first signal and a second signal are captured at the same time, and the optical characteristics of a subject eye and the corneal shape thereof are measured simultaneously or substantially simultaneously. A calculation section captures a received light signal (first signal) from a first light receiving section and a received light signal (second signal) from a second light receiving section at the same timing or substantially the same timing, obtains the optical characteristics of the subject eye on the basis of the first signal, and obtains the corneal shape of the subject eye on the basis of the second signal. A measurement timing decision section decides, on the basis of the first and/or the second signal, measurement timings of the first signal and the second signal as objects for which a measurement calculation is carried out. The measurement timing decision section uses, as a predetermined decision factor for measuring timing, at least one of a blink, a poor tear film, a lack of a pupil diameter, and a poor eyelid. A display section displays, as an image, the first signal and/or the second signal. The operator judges, on the basis of the displayed first signal and/or second signal, suitableness of measurement with the predetermined decision factor for measuring timing, and decides a measurement signal used for the calculation section.

摘要： A subject is placed in a more natural state or is encouraged to blink at specified intervals to obtain a measurement result under a fixed condition, and the judgment of the degree of dry eye is facilitated. A measurement part obtains, based on a reflected light flux from a subject eye, optical characteristic data of a two-dimensional vector form representing the time course of each optical characteristic of the subject eye in an blink interval from a certain blink to a next blink with respect to the first to the nth blink intervals. An analysis part one-dimensionally arranges each of the optical characteristic data with respect to the first to the nth blink intervals measured by the measurement part, and arranges the one-dimensional arrangement of the optical characteristic in a p-th blink interval at a p column to create a two-dimensional array, and performs a principal component analysis processing on the two-dimensional array.

摘要： There is provided an ophthalmologic apparatus which can be effectively used for the clinic of a dry eye by using, as a basic principle, that when a tear film dries up, a corneal shape is changed and/or a wavefront aberration becomes large. When a measurement is started, the ophthalmologic apparatus is aligned. An arithmetic part performs an initial setting of a measurement interval of the apparatus, a measurement time and the like by a wavefront measurement part. An input part or the arithmetic part triggers a measurement start, and the arithmetic part repeats a measurement of the corneal shape and corneal wavefront aberrations by a measurement part until time reaches a measurement end time. When the time reaches the measurement end time, a judgment part analyzes a breakup state as one index for judgment of a state of a dry eye. The judgment part obtains values relating to the breakup to output them, and performs an automatic diagnosis about dry eye on the basis of the values.
