An investigation into the use of the ocular pulse as a diagnostic tool

1 April 1981

Abstract

If the IOP is measured continuously a cyclic fluctuation called the ocular pulse is noted. The diagnostic value of this pulse was studied by screening 80 subjects for their pulse amplitude values which when analyzed on the basis of the subjects' ages, were correlated with the presence or absence of diabetes and hypertension. Once the mean values for each age and condition group were calculated, it was found that, with age held constant, there was no significant difference between the mean values for the normal, diabetic, or hypertensive groups. While the inter-eye variation in ocular pulse amplitude values of one hypertensive population was significantly lower than that of the normal population, this difference approximated the measurement reliability. Still, the norms established by this study were able to isolate one subject with systemic vascular conditions which had not been previously determined by other objective methods.
