摘要:
An ophthalmic ultrasonic diagnosing apparatus for measuring an ocular axial length of an examinees eye includes an ultrasonic probe for A-mode measurement including a transducer arranged to emit an ultrasonic wave toward the inside of the eye, and receive return echoes from eye constituent parts, and an analysis unit for identifying, by analyzing signals of the received echoes, the respective signals as a return echo signal from a cornea of the eye, a return echo signal from an intraocular lens implanted in the eye, multiple return echo signals produced from the signals repeatedly returning between the intraocular lens and the transducer, and a return echo signal from a retina of the eye, while distinguishing the retinal signal from the multiple signals based on a property shown by the multiple signals and/or a property shown by the retinal signal, and calculate the axial length based on the corneal and retinal signals.
