Subjects P1 to P7 have LR palsy. Subjects ET1 to ET3 have nonparalytic ET. MRI was performed before and after strabismus surgery in subject P7, after strabismus surgery in ET2 and ET3, and before surgery in all other subjects.

^*Vertical rectus transposition shifted insertions of the superior and inferior rectus muscles to abut the LR insertion on the sclera and were augmented with scleral sutures 8 mm posteriorly to shift further the vertical rectus pulleys temporally
