Uveitis: recurrent

Synonym(s): Periodic ophthalmia, Moon blindness, Iridocyclitis

Contributor(s): Joe Bertone

Introduction

  • Cause: idiopathic uveitis is characterized by lack of evidence of obvious etiology.
  • Incidence: single or recurrent (more usual) episodes of clinical signs of a varying periodicity.
  • Signs: sudden onset unilateral or bilateral (more usual) acutely painful eye   →   progressive, irreversible ocular pathology with increasing numbers of flare-ups; a whole range of acute and chronic ocular changes varying with individual cases.
  • Treatment: rapid and intense topical and systemic therapy to minimize long-term sequalae.
  • Prognosis: guarded: see equine anterior uveitis: overview   Uveitis: anterior - overview  .
  • A common cause of blindness in horses.

Pathogenesis

Etiology

Pathophysiology

  • Idiopathic uveitis - characterized by the absence of historical or clinical evidence of an obvious etiology.
  • A single or recurrent (more usual) acute episode of uveitis with a varying periodicity.
  • Probably a group of immunologically mediated, etiologically and pathologically distinct conditions.
  • Recurring episodes of acute anterior uveitis and/or chorioretinitis/optic neuritis are associated with progressive, irreversible ocular pathology which is dependent upon the severity and duration of each exacerbation and the promptness/effectiveness of therapy.
