eFigure 1. Change in Comitance Based on Prior Strabismus Surgery
A
B
In both groups, induced incomitance was smallest in the symmetric group (p < 0.0001).
There was a significantly larger change in comitance in the 3-muscle re-operation group
(p = 0.01) compared with the other groups. Error bars indicate standard deviation.

Asymmetric vs Symmetric Surgery and by Procedure Type
A
B
Asymmetric surgery had the largest CIC (p < 0.0001), and none of the asymmetric
procedure types (1-muscle, 2-muscle asymmetric and 3-muscle surgery) had more CIC
than the others (P=0.67). Error bars indicate standard deviation.

B
No age-based differences in subgroups were observed (P>0.05 in all instances.) Error
bars indicate standard deviation.

No correlation between the change in comitance and the surgical dosage was gleaned.

Strabismus Surgery
B
A
Overall there was no significant difference between groups (p = 0.21) Among
subgroups, there was a larger CIC in patients undergoing simultaneous vertical rectus
and oblique surgery (p = 0.006.) Error bars indicate standard deviation.
