Magnetic resonance imaging of the functional anatomy of the inferior oblique muscle in superior oblique palsy.
PURPOSE To study size and contractility of the normal inferior oblique (IO) muscle using high-resolution magnetic resonance imaging (MRI) and to evaluate abnormalities of the superior oblique (SO) and IO muscles in chronic SO palsy. DESIGN Prospective, case control study. PARTICIPANTS Thirteen patients with SO palsy and 17 orthotropic subjects. METHODS High-resolution, surface coil MRI wa...
متن کاملMagnetic resonance imaging of the functional anatomy of the superior oblique muscle.
PURPOSE To study the size and contractile changes of the normal superior oblique (SO) muscle using high-resolution magnetic resonance imaging (MRI), and to evaluate the abnormalities in these characteristics produced by SO palsy. METHODS Multiple coronal MRI image planes were obtained using a surface coil to span the antero-posterior extent of each orbit and were repeated in multiple directio...
متن کاملSuperior Rectus Muscle Recession for Residual Head Tilt after Inferior Oblique Muscle Weakening in Superior Oblique Palsy
PURPOSE Residual head tilt has been reported in patients with superior oblique muscle palsy (SOP) after surgery to weaken the inferior oblique (IO) muscle. The treatments for these patients have not received appropriate attention. In this study, we evaluated the superior rectus (SR) muscle recession as a surgical treatment. METHODS The medical records of 12 patients with SOP were retrospectiv...
متن کاملInferior oblique muscle anteriorization in congenital superior oblique palsy.
BACKGROUND Inferior oblique muscle overaction of variable amounts is usually present with congenital superior oblique palsy. Inferior oblique muscle anteriorization has been described as a suitable surgical procedure in this entity. The aim of this study was to investigate the effect of inferior oblique muscle anteriorization in patients with congenital superior oblique palsy on vertical, torsi...
متن کاملSurgical effects of nasal transposition of inferior rectus muscle – 135 cases of acquired superior oblique palsy
Nasal transposition of the inferior rectus (IR) muscle, which is transposed nasally with the insertion parallel to the spiral of Tillaux, could correct excyclotropia. However, as far as we are aware, there have been no reports examining the surgical effects of this procedure in multiple cases. Therefore, we examined the surgical effects of IR nasal transposition in 135 cases with acquired troch...
