Eccentricity is the distance between the PRL and the fovea in degrees of visual angle. The retinal fovea location was determined from the normal fixation position relative to the optic disk.17
†
Polar angle is the angle between the upward vertical axis from the fovea and a line connecting the PRL and the fovea in a clockwise direction in visual field coordinates.
‡
Fixation stability is defined as the diameter of the retinal region, in degrees of visual angle, where fixation points were located during a 20-second SLO fixation stability test (visual inspection of retinal motion during fixation of a 1° fixation cross).
