Eyelid: blepharedema

pequis

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.
