Description
This eye movement abnormality presents with intermittent monocular oscillopsia, often following a particular eye movement or head tilt. The examiner will often miss the abnormality unless it can be provoked. It represents a microtremor of a superior oblique muscle and usually responds to an anticonvulsant, particularly carbamazapine. A patient with this condition in the right eye is shown.
