Optic neuropathy in Paget's disease.
Of 22 patients (18 men and four women ranging in age from 50 to 89 years) with radiographic and clinical evidence of Paget's disease, nine had visual field defects. All nine had arcuate scotomas and five of the nine had generalized constriction. The visual field changes were asymptomatic in six of nine patients and progressive in two patients. Only two patients had radiographic evidence of optic canal constriction by bony impingement. There was no objective improvement in the optic neuropathy in the three patients treated with synthetic salmon calcitonin. Our data suggested that the optic neuropathy of Paget's disease cannot be explained solely on the basis of bony compression and the cause of optic neuropathy in patients with normal optic canals remains unknown.
