Sympathetic ophthalmia is a rare, bilateral granulomatous uveitis that occurs after either surgical or accidental trauma to one eye. The ocular inflammation in the fellow eye becomes apparent usually within 3 months after injury. Clinical presentation is an insidious or acute anterior uveitis with mutton-fat keratic precipitates. The posterior segment manifests moderate to severe vitritis, usually accompanied by multiple yellowish-white choroidal lesions. Evidence suggests that sympathetic ophthalmia represents an autoimmune inflammatory response against choroidal melanocytes mediated by T cells. Diagnosis is based on clinical findings and a history of previous ocular trauma or surgery. Other causes of granulomatous uveitis, such as Vogt-Koyanagi-Harada disease, sarcoidosis, tuberculosis, and syphilis should be considered. Treatment of sympathetic ophthalmia consists of systemic anti-inflammatory agents with high dose oral corticosteroid as the drug of choice. However, if the inflammation cannot be controlled, cyclosporine is then used. Other immunosuppressive agents, such as chlorambucil, cyclophosphamide or azathioprine, may be necessary for the control of inflammation. The role of enucleation after the diagnosis of sympathetic ophthalmia remains controversial. Visual prognosis is reasonably good with prompt wound repair and appropriate immunomodulatory therapy.
