Modification of the standard recession of the inferior oblique muscle for overacting inferior obliques has been performed by the authors. The inferior oblique has been detached from the globe as in the usual recession procedure, but has been reattached slightly anterior to the temporal border of the insertion of the inferior rectus. The results in 64 anterior transpositions are compared to the results in 90 standard recessions varying from 8 to 14 mm in magnitude. Our analysis shows that anterior transposition appears to be an effective procedure in eliminating inferior oblique overaction. It also produced excellent results in seven cases in which inferior oblique overaction persisted following previous standard recessions. This procedure appears to have excellent applicability in persistent and, possibly, marked cases of overaction of the inferior oblique.
