Superior Oblique Myokymia – A Case Study

Bronwyn Jennings, BappSc(Orth)

Superior Oblique Myokymia is a rare spasmodic contraction of the superior oblique muscle giving rise to monocular vertical and rotary microtremor and accompanied by torsional shimmering oscillopsia. A fifty-five year old woman presented with a long history of right ocular discomfort and a lack of synchronisation between the eye movements of the two eyes without diplopia. This was diagnosed as being due to right superior oblique Myokymia. The unusual clinical presentation of this condition is discussed and treatment options outlined.
