The pathology of the optic nerve in the advanced elderly has been investigated at autopsy in a sample of 50 subjects (43 males, 7 females), aged 95-103 years. Septal fibrous thickness and slendering of nerve fibers were the most frequently encountered lesions as well as degenerative processes involving the cribriform lamina. Other significant features included gliosis, demyelination, and corpora amylacea. Complete arteriosclerotic disease was rarely observed. The results of the present study suggest that optic nerve pathology in aged people is almost the consequence of an inadequate blood supply; nevertheless, the degree of these lesions does not seem to parallel that usually observed in other sites particularly injured by ischemic disease.
