Exophthalmos – Rabbit

From WikiVet English
Jump to navigation Jump to search

Introduction

Unilateral exophthalmos (Wagner F et al 2005) may be caused by:

  • Orbital abscesses (is this the same as retrobulbar abscesses)
  • Orbital cellulites
  • Orbital cysts
  • Retrobulbar fat prolapse
  • Salivary mucocoele
  • Orbital neoplasia
  • Taenia serialis - coenurosis

Bilateral exophthalmos may be caused by, I assume, the above occurring bilaterally and also by:

  • Thymoma (Vernaue et al 1995)
  • Mediastinal lymphoma (Wagner F et al 2005)
