Eyelid: trauma – contusion and abrasion
Introduction
- Cause: blunt injuries of the eyelid without skin disruptions cause contusions, while disruption of the cutaneous epithelial barrier is an abrasion.
- Signs: may be associated with other more serious globe or orbital injuries.
- Treatment: rapidly respond to symptomatic treatment.
- Prognosis: fair to good without any complications.
Presenting signs
- History of blunt trauma.
- With or without skin penetration.
- Eyelid swelling.
- Decreased lid function.
Cost considerations
- Treatment.
Pathogenesis
Etiology
- Direct blunt trauma.
Pathophysiology
- Contusions are blunt injuries of the eyelid without skin barrier disruption whereas abrasions have loss of skin epithelial tissue.
- Both may be associated with serious injury to the globe or orbit Orbit: trauma .
- The eyelids in the horse lack dermal fatty tissue and hematomas develop readily (contusions).
- Loss of the epithelial barrier may allow infection to establish with possibilities of orbital cellulitis Orbit: cellulitis or retrobulbar abscess Orbit: retrobulbar abscess formation.
- Lid abscesses may also occur.
