A 61-year-old man presented with 2 days of "flickering" vision. The symptom resolved with closure of the left eye. Examination demonstrated involuntary high-frequency, low-amplitude intorting movements of the left eye, consistent with superior oblique myokymia (Video 1). Ocular ductions were full, and there were no abnormal movements of the right eye.
