Ferrets

Ocular lymphoma

Contributor(s): Cathy Johnson-Delaney, David Perpinan

Introduction

  • Signs: lymphoma of the tissues surrounding the eye, may be diffuse or more definitive mass; can also affect the eye producing visual deficits.
  • Diagnosis: ophthalmic examination, ocular tissue biopsy.
  • Treatment: tissue excision, glans nictitans removal, topical prednisolone.
  • Prognosis: poor for multicentric lymphoma.

Pathogenesis

Etiology

  • The eye itself is not the site of the lymphoma.
  • There may be enlargement on the bulbar surface of the glans nictitans.
  • One or both of the eyes may be affected.
  • If the mass enlarges, it may proptose the globe and cause blindness.

Epidemiology

  • Neoplasia of the eye and orbit is uncommon in ferrets.
  • Malignant lymphoma is the most common neoplasm in both the eye and the orbit.
