Fig. 6. Synchrony of color-encoded trabecular meshwork and cardiac pulse.

Fig. 6.

(A) Representative structural image captured by OCT. (B) Heartbeat signals obtained from a digital pulsimeter shows the frequency domain positions (red markings). The trabecular meshwork (TM) motion signal is the filtered frequency domain TM motion (black trace, synchronized with the heartbeat signal. (C) Color-encoded instantaneous velocity is overlaid on the structural image. Red indicates anterior tissue movement toward the probe above the scleral surface. Blue indicates posterior tissue movement toward the anterior chamber. Tissue source: Human subject. From Xin C, Pulse-dependent TM motion in normal humans using phase-sensitive OCT.
