Superior oblique myokymia: quantitative description of the eye movement.
We studied superior oblique myokymia (intermittent uniocular microtremor) using magnetic scleral search coils. The monocular disorder consisted of both phasic and tonic components consistent with the primary, secondary, and tertiary actions of the superior oblique muscle. These observations support the hypothesis of a disorder restricted to the superior oblique motor unit.
