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.

Pyogenic Granuloma on Eye

This ophthalmology finding is somewhat rare. Not only can pyogenic granulomas form on the inner eyelid (for example, at the site of a chalazion) they can also form on the bulbar conjunctiva. Typically treat with steroids and tears ... and if it doesn't melt away, than consider a surgical excision.
