Abstract

The microscopic and ultrastructural modifications of glial and mesenchymal components of the optic nerve in the physiologic aging were studied in 182 human optic nerves. According to the age of subjects, a modification of topography of astrocytes was observed. In the 7th-8th decade, the axons of the optic nerve showed some phenomena of swelling and axonal degeneration. During the years, the central artery of retina showed an evident hyperplasia of intima and an increase of collagen of the media. While the connective tissue was good represented by the end of the 1st decade in the central vein of retina, the muscular tissue was almost absent. The interfascicular connective tissue increased considerably in the aging.
