Idiopathic orbital inflammation: ocular mechanisms and clinicopathology.

Pathogenesis of idiopathic orbital inflammation remains elusive but several lines of evidence point to immune-mediated processes as the likely underlying ocular mechanism. The exact nature of the immunological process and possible role of infection need to be elucidated in greater depth. There is an obvious need for a more satisfactory animal model for orbital pseudotumor. Given the prevalence of recurrent and persistent orbital inflammation, therapeutic alternatives to corticosteroids need to be further explored and systematically investigated.
