Frequency of Fast Fixation Eye Movements (Hertz) During Dichoptic Viewing Across the Four Groups

Groups	FE Contrast 100%	FE Contrast 50%	FE Contrast 25%	FE Contrast 10%
Group 0	0.74 ± 0.32	0.86 ± 0.40	0.96 ± 0.35	0.95 ± 0.50
Group 1	1.1 ± 0.42	0.95 ± 0.35	0.93 ± 0.33	0.94 ± 0.34
Group 2	1.1 ± 0.54	1.2 ± 0.53	1.2 ± 0.55	1.2 ± 0.42
Group 3	2.2 ± 1.3	2.1 ± 1.2	1.9 ± 0.79	1.9 ± 1.3

FE = fellow eye contrast varied at 100%, 50%, 25%, and 10% while amblyopic eye contrast was at 100% for all dichoptic viewing trials.

Group 0 = controls, group 1 = anisometropic amblyopia, group 2 = mixed/strabismic amblyopia without fusion maldevelopment nystagmus, and group 3 = mixed/strabismic amblyopia with fusion maldevelopment nystagmus.
