APLASIA of the optic nerve occurring as an isolated abnormality in an eye of normal external appearance is rare. It is seen more frequently in association with more obvious developmental anomalies of the eye and its adnexa, and with such gross defects as anencephaly.

متن کاملLipofuscin in human glaucomatous optic nerves.
Lipofuscin accumulation has been observed in a number of neurodegenerative diseases. We recently found that autofluorescent particles also occur in the aged human optic nerve. In this study we sought to determine the nature of these particles and their correlation with aging, age-related macular degeneration (AMD) and primary open angle glaucoma (POAG). Groups of eight optic nerves from patient...
