It’s  signal a serious condition related to a skull or brain injury. Prompt diagnosis is crucial to reduce the risk of complications.

What Causes raccoon eyes?

It is most often caused by a basal skull fracture (BSF). The basal part of your skull is the bottom portion where the brain rests. When a fracture occurs, symptoms such as raccoon eyes may follow. BSF can occur from car accidents, falls, sports injuries, and other sources of head trauma.

Another possible cause of it is the breaking of the thin bones that surround your eyes. This can result from facial injuries. A broken nose or broken cheekbones are other possible causes.
