Contributor(s):

David L Williams


Introduction

  • Cause: toxoplasmosis in a small number of cases - mostly idiopathic.
  • Signs: episcleritis is a differential diagnosis for the red eye and may cause ocular irritation but rarely visual disturbance.
  • Diagnosis: a differential diagnosis of the red eye.
  • Treatment: topical steroid as a main treatment.

Pathogenesis

Etiology

  • Has been associated with Toxoplasma infection but only rarely.

Pathophysiology

  • In man, scleritis is often associated with rheumatoid arthritis but no such link with connective tissue disorders is seen in the dog.
  • There seems to be no obvious etiopathogenic mechanism underlying episcleritis and scleritis in the dog. Indeed, the pathology from different cases can be quite varied, suggesting different pathways to disease occurence.
