• Five patients with a clinical diagnosis of buried or exposed drusen of the optic nerve head were examined by computerized tomography (CT). The relative x-ray absorption within their nerve heads was significantly larger than in controls, reflecting the high calcium content of drusen. Computerized tomography, and particularly high-definition CT, therefore merits consideration in the investigation of disc swelling.
