Overview. Eye contusion is a bruise around the eye. It may involve the eye, eyelid, eye socket, and associated muscles and is usually the result of a blunt injury to the eye.
The eyes are particularly prone to contusions because the skin lies close to the underlying bone and there is little muscle or fat to protect fragile small blood vessels.Incidence and Prevalence: Contusions are very common. Approximately 2.4 million eye injuries occur in the US annually (Eye Trauma).
