Dorsal Midbrain Syndrome With Bilateral Superior Oblique Palsy Following Brainstem Hemorrhage

Dorsal midbrain syndrome with bilateral superior oblique palsy following brainstem hemorrhage.

Lesions affecting the dorsal midbrain can result in a constellation of ocular findings such as vertical gaze disturbances, convergence retraction nystagmus, light-near dissociation of pupils, and eyelid retraction. Although bilateral superior oblique palsy can occur after a stroke, its occurrence secondary to nontraumatic brainstem hemorrhage is extremely rare. We report a combination of dorsal...

When does masked bilateral superior oblique palsy occur in children?

Bilateral superior oblique palsies.

Eighteen consecutive cases of bilateral superior oblique palsy have been studied retrospectively. The patients were typically adults with a history of severe head trauma. All patients complained of diplopia, either vertical, torsional, or both. Other neurological sequelae were common. Central disruption of fusion was seen in three patients. Eight patients underwent surgery for torsional or vert...

Inferior 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...

Extraocular Muscle Compartments in Superior Oblique Palsy

Purpose To investigate changes in volumes of extraocular muscle (EOM) compartments in unilateral superior oblique (SO) palsy using magnetic resonance imaging (MRI). Methods High-resolution, surface-coil MRI was obtained in 19 patients with unilateral SO palsy and 19 age-matched orthotropic control subjects. Rectus EOMs and the SO were divided into two anatomic compartments for volume analysis...
