Fig. 3. Refractive error correlations. (A) Positive correlation of refractive error with pulse amplitude (OBFa) (r = 0.729, p < 0.001). (B) Positive correlation of refractive error with pulse volume (OBFv) (r = 0.772, p < 0.001). (C) No significant correlation of refractive error with pulse rate (OBFr) (r = -0.157, p = 0.113). (D) Positive correlation of refractive error with pulsatile ocular blood flow (POBF) (r = 0.781, p < 0.001). D = diopters.
