摘要:
Described is a system, method and apparatus for measuring a vibrational response in an eye for determination of ocular parameters such as intraocular pressure, corneal elasticity and scleral pressure. The method comprises positioning an air jet nozzle to direct an excitation stimulus at a single frequency to the apex of the eye along the optical axis of the eye; positioning a sensor to direct incident light at a fixed position of the eye distinct from the apex of the eye; exciting vibration in the eye with the excitation stimulus; directing incident light from the sensor to the fixed position of the eye; and detecting backscatter light from the eye with the sensor, to measure the vibrational response. Algorithms are used to calculate the ocular pressure from the vibrational response of the cornea or sclera. The method does not require contact with the eye, and is reliable and accurate.
