Superior Oblique Myokymia

This is an uncommon ophthalmology finding. With this disorder, the superior oblique muscle spasmically fires, and the eye rotates. Look closely at one of the conjunctival vessels and you can see it move. This is different than rotary nystagmus, as nystagmus are more rhythmic.
