Group O was further divided into subgroups Z and M, 26 eyes each. Subgroup Z underwent inferior oblique Z (2 cuts) myotomy to treat grade 1 or 2 inferior oblique overaction, while subgroup M underwent inferior oblique M (3 cuts) myotomy to treat grade 3 or 4 inferior oblique overaction, thus termed \u201cgraded marginal myotomy\u201d.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A successful outcome was achieved in 25\/26 patients (96.2%) in Group O and 9\/13 patients (80.8%) in Group E,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .035, after 6 months of postoperative follow-up.
