摘要：Purpose
To compare ocular pulse amplitude (OPA) measured using dynamic contour tonometry (DCT) and ocular blood flow analyzer (BFA).
Methods
Thirty-five eyes of 35 patients were enrolled in this cross-sectional and retrospective study. OPA was measured using DCT. Pulse amplitude (PA) and pulsatile ocular blood flow were measured using BFA.
Results
OPA measured using DCT (2.79 ± 0.89 mm Hg) was not significantly different from PA measured with BFA (3.02 ± 0.90 mm Hg; p = 0.082) and both were significantly correlated (r = 0.663, p < 0.001). Mean difference ± limit of agreement was -0.22 ± 1.44 mm Hg between OPA and PA. OPA correlated significantly with intraocular pressure (IOP) measured using Goldmann applanation tonometry (r = 0.330, p = 0.047) but not PA (r = 0.057, p = 0.745). Both PA and OPA did not show significant correlation with the spherical equivalent of refractive error and central corneal thickness.
Conclusions
Although both OPA and PA measure IOP fluctuation and are not significantly different, they showed different relationships with IOP.
