A 20-year-old woman with diabetes, hypertension, and hypothyroidism had a 3-day history of severe pain and vision loss in the left eye. She also noticed a slowly enlarging nodule on the left eye over the previous 5 months. Review of systems was negative for fever. Visual acuity was 20/20 OD and counting fingers OS. Intraocular pressure was 43 mm Hg OS. Examination showed an elevated perilimbal subconjunctival nodule, large keratic precipitates, 3+ anterior segment inflammation, 2+ vitreous haze, and subretinal exudate (Figure 1A and B). Ultrasonography revealed diffuse scleral thickening. Laboratory testing revealed no leukocytosis, a normal angiotensin-converting enzyme level, a nonreactive rapid plasma reagin test result, and a slightly elevated erythrocyte sedimentation rate (25 mm/h). Tuberculosis skin testing and chest radiography results were normal. Results of testing for antinuclear antibodies, anticytoplasmic nuclear antibodies, and HLA-B27 were negative.
