A 55 year old man with rheumatoid vasculitis and an apparent left inferior oblique palsy is described. This unusual extraocular complication of rheumatoid arthritis probably resulted from a tenosynovitis of the superior oblique tendon sheath, and resolved with steroid treatment.

PURPOSE To evaluate the outcome of strabismus surgery for congenital superior oblique palsy (SOP) in relation to correction of head tilt and hypertropia. The cohort of patients mainly involved very young children. This is the first study to use a standardized instrument to objectively measure torticollis before and after surgery. MATERIALS AND METHODS A non-comparative interventional case ser...

BACKGROUND Refractive errors, strabismus, nystagmus, amblyopia, and cortical visual impairment are observed in 50 to 90 % of patients with cerebral palsy. Ocular abnormalities are known to differ according to cerebral palsy type, and spastic type has been reported to be more likely to be associated with ocular defects than the athetoid and ataxic types. METHODS A retrospective review of medic...

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...

I n t e rnational scholars have addressed various issues related to superior oblique palsy (SOP) many times in recent years owing to its epidemiologic relevance (1-3). Recently, it has been recognized as a leading cause of anomalous head posture in the pediatric age group (4). In this issue, two studies analyze the results of inferior oblique (IO) weakening pro c e d u res in the treatment of S...

The purpose of this study is to know clinical factors underlying either a single surgery or repetitive surgeries, required to treat superior oblique muscle palsy. Retrospective review was made on 246 consecutive patients with idiopathic (n = 212) or acquired (n = 34) superior oblique muscle palsy who underwent surgeries in 8 years at one institution. Idiopathic palsy included congenital and dec...

PURPOSE We report a patient with abnormal head posture following ocular blunt trauma. METHODS This is report of a case that despite findings compatible with diagnosis of left superior oblique (SO) palsy, the patient acquired an ipsilateral (left) head tilt. The interesting observation in our patient was reduction of left hypertropia and consequent less diplopia with ipsilateral head tilt. R...

PURPOSE To study causes of overcorrection after surgery for unilateral oblique superior palsy and treatment options. METHODS Nine cases with overcorrection following surgery for unilateral oblique superior palsy between 2004 and 2006 were identified. Their causes were divided into three types: excessive surgery, bilateral masked palsy and antielevation or adherence syndrome. Treatment was req...
