Eyelid: blepharedema

Contributor(s): Paul E Miller, Graham Munroe

Introduction

  • Rapid onset of eyelid edema readily occurs in the horse.
  • Cause: both local (unilateral) and systemic (bilateral) causes are documented.
  • Signs: eyelid(s) are swollen and upper lid droops over cornea; restricted lid movement may lead to exposure keratopathy.
  • Diagnosis: full clinical and ophthalmic examination of horse to assess local and systemic causes.
  • Treatment: varies with cause.
  • Prognosis: generally better for local causes.

Pathogenesis

Etiology

Unilateral - local processes

Bilateral - systemic processes

Pathophysiology

  • Eyelid edema (blepharedema) readily occurs in the horse because of the relative lack of fat in the eyelid dermis.
  • Both local and systemic causes are known.
  • A thick swollen upper eyelid may droop and eyelid function may be compromised.

Timecourse

  • Rapid onset <24 h.
