Color fundus, ICGA, OCT, and OCA images of PCV obtained from the left eye of a 77-year-old man. Color fundus photographs (
A) show multiple PEDs with subretinal hemorrhage. An
orange-red spot (
white arrow) is observed in the macula. In the ICGA images, branching vascular networks overlying the large choroidal vessels (
white arrow) are evident in the early phase (
B), and polypoidal lesions adjacent to the vascular network (
white arrows) are readily seen in the late phase (
C).
Black line: area of Doppler OCT imaging;
white line: scanning line of B-scan OCT images (
D,
E). An intensity B-scan OCT image (
D) shows the space between the RPE and Bruch's membrane. Bidirectional color Doppler B-scan OCT image (
E) shows the presence of blood flow in the space between the RPE and Bruch's membrane. Doppler OCA image superimposed on ICGA images (
F) shows the distribution of the Doppler signals in the space between the RPE and Bruch's membrane; this distribution corresponds well with the area of the abnormal vascular network in the ICGA image. The same color codes as in
Figure 7 were used in the Doppler OCA image.
Black line: area of Doppler OCA imaging.
