  1. LogMAR = logarithm of the minimum angle of resolution. Five eyes were excluded from the analysis because retinal perfusion status could not be determined due to blockage by a dense retinal hemorrhage. Retinal perfusion status was determined in a central area between the fovea and the point where a vertical line through the fovea and the affected arcade vessels intersect.
