Anatomy of the orbit

Retrobulbar bleeding, also known as retrobulbar hemorrhage, is when bleeding occurs behind the eye.[1] Symptoms may include pain, bruising around the eye, the eye bulging outwards, vomiting, and vision loss.[1] Complications may include orbital compartment syndrome (OCS).[2]

Retrobulbar bleeding can occur as a result of trauma to the eye, surgery to the eye, blood thinners, or an arteriovenous malformation.[1]

In those with significant symptoms lateral canthotomy with cantholysis is indicated.[1] This is recommended to be carried out within two hours.[1] The condition is rare.[1]
