  • If the patient presents with a secluded pupil from extensive posterior synechiae, iris bombe with angle-closure glaucoma may be present. Perform iridotomy as soon as possible (after quieting the eye with anti-inflammatory medications).[emedicine.medscape.com]
Cat Scratch
  • […] lymphadenopathy Known risk factors Treatment with fine needle aspiration: amylase in cyst fluid confirms diagnosis Actinomycosis May be acute or chronic, usually with history of dental trauma Anaerobic culture for diagnosis Treat with long-term penicillin therapy Cat-scratch[medicine.uiowa.edu]

Prognosis

  • Prognosis and recovery time of the patient with ocular uveitis If left untreated, uveitis can cause loss of vision.[hickeysolution.com]

  • Prognosis Some forms of AAU have a tendency to recur.[eyewiki.aao.org]
  • The prognosis of AAU associated with AS is generally good; each acute attack usually responds to topical corticosteroid drops with or without cycloplegics.[the-rheumatologist.org]

Etiology

  • In severe cases of iritis, oral corticosteroids may be added to the treatment regimen (after ruling out the infectious etiology or after under coverage of medication, which treats the infectious etiology).[emedicine.medscape.com]
  • Increased intraocular pressure at the onset may suggest a viral etiology, particularly in unilateral disease.[emedicine.medscape.com]
  • Although certain etiologies may be more common in certain parts of the world (eg, TB in endemic areas). Mortality/Morbidity Morbidity may arise from both the iritis and any associated systemic disease if present.[emedicine.medscape.com]
