Eye Alignment (Degrees) During Dichoptic Viewing Across The Four Groups

Groups	FE Contrast 100%	FE Contrast 50%	FE Contrast 25%	FE Contrast 10%
Group 0	0.80 ± 0.42 2.0 ± 0.41	0.72 ± 0.56 2.1 ± 0.76	0.96 ± 0.66 2.3 ± 0.83	1.4 ± 0.67 2.9 ± 0.98
Group 1	0.72 ± 0.55 2.4 ± 1.7	0.38 ± 0.47 2.2 ± 1.7	0.70 ± 0.97 2.2 ± 1.7	0.63 ± 0.79 2.2 ± 1.6
Group 2	1.9 ± 1.8 4.7 ± 3.3	2.0 ± 2.2 4.7 ± 3.2	2.1 ± 2.2 5.7 ± 3.7	2.2 ± 2.7 5.7 ± 4.6
Group 3	4.3 ± 4.3 6.5 ± 4.7	3.7 ± 3.2 5.4 ± 3.6	3.8 ± 2.9 5.9 ± 3.6	4.3 ± 3.5 6.7 ± 4.2

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

The 95% lower bound (top row) and 95% upper bound (bottom row) of the histogram of composite eye position difference between the right and left eyes.

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