Abstract

We use Spatio-Temporal Optical Coherence Tomography (STOC-T) to record flicker ORG signals. The chirped frequency stimulus (5 Hz to 45 Hz) provides a more convenient way of measuring photoreceptors' frequency characteristics. Our method detected significant differences in response amplitudes in two measured subjects when comparing responses to different stimulus amplitudes as well as when comparing responses to rectangular and sinusoidal stimulation.
