IgG serology for toxoplasmosis. The patient was a young female with red painful eyes, bilateral eyelid edema, and panuveitis with periphlebitis. In laboratory testing, she was IgM and IgG positive for toxoplasmosis and anergic in the tuberculin test. Topical treatment for anterior uveitis and oral antibiotics for toxoplasmosis were started, without improvement. Orbit tomography showed increased lacrimal glands bilaterally, and chest X-ray radiographic findings were consistent with pulmonary sarcoidosis, which supported the presumed ocular sarcoidosis diagnosis. The patient was treated with oral prednisone and methotrexate without antibiotics. She showed clinical and vision improvement without recurrences during the 1-year follow-up. Ocular sarcoidosis is an important differential diagnosis requiring careful anamnesis and ophthalmological examinations. Ancillary tests, such as X-ray radiography, tomography, and clinical and laboratory evaluations may help rule out other causes. Treatment mainly consists of corticosteroids and immunosuppression.
