Eye Alignment (Degrees) During Monocular and Binocular Viewing Across the Four Groups

Groups	BEV (degrees)	FEV (degrees)	AEV (degrees)
Group 0	0.75 ± 0.82 2.17 ± 0.91	0.67 ± 0.75 2.6 ± 1.0	0.78 ± 0.68 3.4 ± 1.3
Group 1	2.0 ± 2.4 5.1 ± 4.2	2.5 ± 3.1 5.0 ± 3.9	1.9 ± 3.3 4.6 ± 5.1
Group 2	1.7 ± 1.9 3.8 ± 2.7	4.4 ± 3.8 7.6 ± 4.1	4.5 ± 4.4 7.5 ± 6.3
Group 3	6.2 ± 6.1 9.6 ± 8.6	9.8 ± 8.9 13.5 ± 8.6	5.6 ± 6.0 9.1 ± 5.8

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.

BEV, both eye viewing; FEV, fellow eye viewing; AEV, amblyopic eye viewing.

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.
