A Clinical Case from the Archives : 30/07/2005

This dog has a localised area of redness in the left eye. Are there other signs that aid you in your diagnosis? Might there be a systemic disaese associated with this condition?

Note the scleral swelling here too. This is scleritis. In man the systemic association is with a more generalised connective tissue disease be it rheumatoid arthritis or Wegener’s granulomatosis though we don’t seem to see this connection in the dog. This animal also has an epitheliotropic lymphoma – lymphoma masquerading as apparent scleritis is certainly seen in man (Dorey Orbital lymphoma misdiagnosed as scleritis. Ophthalmology. 2002 109:2347-50 for example), though this is the first case I’ve seen in the dog.
