purpose: to determine the effect of recession and myectomy on inferior oblique overaction (iooa). method: this study was performed on 50 patients (82 eyes) scheduled for iooa surgery who were randomly divided into two groups: recession (r) versus myectomy (m). a complete eye examination was performed before the operation. io was cut off at its inferior temporal region when using m procedure. in...

OBJECTIVE To seek evidence for causative secondary changes in extraocular muscle volume, cross-sectional area, and contractility in superior oblique (SO) palsy using magnetic resonance imaging, given that vertical deviations in SO palsy greatly exceed those explained by loss of SO vertical action alone. METHODS High-resolution, quasi-coronal orbital magnetic resonance images in target-control...
