A 37-year-old man with a history of sarcoidosis, hypertension, asthma, depression and prior intravenous drug use presented with complaints of difficulty in finding his way around the house, headache, and blurred vision in both eyes. The symptoms had been increasing in severity over the prior several months. Physical examination showed normal visual acuity, pupil reactions, and fundi but severe, circumferential constriction of the visual fields bilaterally. The visual fields enlarged appropriately on increasing the distance from the patient to the tangent screen. Neuroimaging revealed bilateral, occipital meningeal involvement and parenchymal lesions consistent with sarcoidosis. Treatment with oral corticosteroids produced a mild subjective improvement in the patient's symptoms and stabilized the visual fields, without improving them. This case represents an unusual presentation of presumed neurosarcoidosis involving the visual pathways at the level of the occipital lobes.
