Coil embolization of a congenital orbital varix in a dog.

A 10-week-old Labrador Retriever was examined because of a swelling above the left eye. Ophthalmic examination revealed a tubular, light-pink, slightly raised lesion of the left conjunctiva that extended from the limbus to the fornix and into the dorsal eyelid. The lesion affected the entire margin of the dorsal eyelid and extended 2 cm dorsal to the eyelid margin.
