Non-contact ultrasonic tonometer |
摘要 |
A non-contact ultrasonic tonometer for measuring an intraocular pressure of an examinee's eye (E) in non-contact manner by use of an ultrasonic wave, comprises: an ultrasonic transducer (10) including a transmitter (11) which emits an ultrasonic transmission pulse wave to the eye and a receiver (13) which detects an ultrasonic reflection pulse wave from the eye, the transducer being arranged to be placed in a position apart from the eye and to transmit and receive the pulse wave with respect to the eye through the medium of air; and a calculation part (70) being arranged to obtain a peak amplitude level of the reflection pulse wave based on an output signal from the ultrasonic transducer and measure the intraocular pressure based on the obtained peak amplitude level.
