(A) DPPR induced by HFL in the right eye of a 60-year old female subject, color coded over 45 degrees. (B) Circumferential average of the DPPR map in (A). Similar results are shown for the left eye of a 50-year old female (C, D). Error bars represent one standard deviation of the circumferential trace. Note the elevated DPPR in the lower left corner of the map in (A) due to the birefringent RNFL. This subject had a relatively thick RNFL and large blood vessel at this location that together caused the reference (which was chosen using a fixed offset to the location of the IS/OS) to intersect the RNFL. While the resulting DPPR is high, the corner falls outside the circumferential average window (<7.5° retinal eccentricity) that was used for processing.
