Inferior oblique surgery. Experience at the Mayo Clinic from 1960 to 1981
T. W. Jones Jr, D. A. Lee and J. A. Dyer
Three hundred thirty-seven patients underwent inferior oblique
disinsertions at the Mayo Clinic Rochester, Minn, from 1960 to 1981.
Versions and hyperdeviations in the primary position were recorded
preoperatively and postoperatively. The criteria of a successful result
were (1) correction of diplopia, (2) correction of hyperdeviation in the
field of action of the inferior oblique, and (3) correction of versions in
adduction. Clinical failure was reflected in persistence of hyperdeviation
in primary gaze and persistence of overaction of the inferior oblique
muscle in adduction. A successful result was found in 88% of primary
inferior oblique disinsertions. For secondary inferior oblique overaction,
a successful result was found in 72% of patients. We have found that
inferior oblique disinsertion is a safe, fast, reliable, and effective
weakening procedure with good results.
