We investigated the relationship between value fluctuations in multiple measurements during noncontact tonometer measurements and cardiac rate.Materials and Methods: Forty-two healthy subjects were included and IOP was measured using a noncontact tonometer. The measurement was performed three times each for the right eye and the left eye, for a total of six times. Blood pressure and cardiac rate were measured at the same time as the IOP measurement. Using repeated-measures analysis of variance, we examined whether the measured IOP and cardiac rate fluctuate throughout the day over the course of 4 days.Results: There was a fluctuation in the IOP in a sequence only on day 1 of the four measurement days (P < 0.001). The IOP on day 1 tended to be high for the first and second measurements (P = 0.0111– 0.0015). Systolic blood pressure and diastolic blood pressure did not fluctuate over the 4 days (P = 0.6247 and 0.7132), but cardiac rate was high only on day 1 (P = 0.0276).Conclusion: The IOP on day 1 tended to be high in the first and second measurements. The IOP measured on days 2– 4 did not fluctuate during the sequence of measurements. The cardiac rate measured at the same time as the IOP was high only on the first day.Keywords: intraocular pressure, noncontact tonometer, blood pressure, cardiac rate, repeated measurementTatara SMaeda FTsukahara YHanda TYaoeda KDove Medical Pressarticleintraocular pressurenoncontact tonometerblood pressurecardiac raterepeated measurementOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 4507-4512 (2021)
