Key result
The piezoelectric ocular pulse measurement (POPM) instrument uses a piezoceramic transducer in minimal contact with the cornea to record ocular pulses for diagnosing carotid occlusions.
Describes a novel piezoelectric ocular pulse measurement instrument designed to detect minute corneal displacements for the diagnosis of carotid occlusions.
May enable non-invasive carotid occlusion screening; leaves open prospective clinical validation of the piezoelectric instrument.
This paper describes a new technique to record minute corneal displacements caused by blood pressure pulsations behind the eye. The piezoelectric ocular pulse measurement (POPM) instrument uses a piezoceramic transducer in minimal contact with the cornea. The POPM system is intended to be used in the diagnosis of carotid occlusions which often lead to stroke.
