Physiologic anisocoria under various lighting conditions

Figures & data

Table 1 Comparison of the prevalence of anisocoria under different light levels using various cut-offs

Cut-off	Scotopic (0 lux), %	Low mesopic (0.3 lux), %	High mesopic (3 lux), %	Photopic (675 lux), %
≥0.2 mm	72.5	70.6	76.5	54.9
≥0.4 mm	43.1	43.1	47.1	27.4
≥0.6 mm	19.6	15.7	21.6	19.6

Table 2 Effect of adjusting the cut-off on the prevalence of subjects exhibiting anisocoria under every light condition or at least one condition

Cut-off	Subjects with anisocoria under all light conditions, %	Subjects with anisocoria under at least one condition, %
≥0.2 mm	31.4	100
≥0.4 mm	7.8	72.5
≥0.6 mm	1.9	47.0
