Brown's syndrome is an easily recognizable congenital or acquired ocular motility defect. Typically, there is restriction to active and passive elevation of the eye in adduction. Elevation improves as the eye is rotated out of the field of vertical action of the superior oblique muscle. In abduction, there is little to no elevation deficit. If a hypotropia exists in primary gaze, the patient may present with a compensatory chin-up head posture. We treated a young woman who presented with typical Brown's syndrome that developed shortly after the birth of her first child.
Report of a Case.
A 17-year-old woman developed vertical diplopia less than 2 hours after an uncomplicated vaginal delivery. She denied any history of orbit or facial trauma or any history of rheumatoid arthritis or sinusitis. A photograph taken 1 year earlier revealed no evidence of anomalous head posture, lid fissure asymmetry, or ocular misalignment. On ocular motility
