Functional muscle insertional changes and strabismus after scleral buckling.

We report 3 cases of esotropia following scleral buckling surgery for retinal detachment, a relatively undocumented complication. All patients exhibited alterations at the site of the rectus muscle insertions. In all cases, the distance from the limbus to the functional muscle insertion was increased, highlighting the importance of considering the functional muscle insertion in strabismus surgery after scleral buckling.
