Potential explanation for observed flow patterns in the choriocapillaris. (A) The choriocapillaris is a dense mesh of capillaries as shown in red and in the posterior pole the intercapillary pillars are small (shown in black). (B) The presence of ghost segments (white arrow) occurs with age, but is more common in eyes with drusen and with pseudodrusen. (C) The induced flow abnormality is larger than the segment and is shown in as the blue gradient. (D) To produce a power law relationship, two features need to be present. Additional segments need to become nonfunctional over time and the location of these nonfunctioning segments should have a tendency to occur in the vicinity of an already nonfunctional segment.
