Figure 4: Doppler OCT images of the feeder vessel. In the high-magnification Doppler OCT angiography image of the feeder vessel (A), thedistribution of Doppler signals from the retina, choroid, and the space between the RPE and Bruch’s membrane are color-coded blue, green,and red, respectively. The transition point from green to red represents the penetration site of the feeder vessels through Bruch’s membrane.A series of colored Doppler OCT images (B) show penetration of the feeder vessels across Bruch’s membrane, and arrows indicate theposition of Doppler signals in the colored Doppler OCT images.
