Optic Disc Atrophy

Optic disc atrophy is a condition of the optic nerve in which the number of neurons is decreased, the shape of the nerve rim thins, and the color becomes pallid.Ê The patient may experience blurred vision, decreased peripheral vision, decreased color vision and an overall reduction in the visual field and contrast sensitivity. There are many causes for optic atrophy, including diminished blood flow, glaucoma, optic neuritis, and compression of the optic nerve, trauma, sterile inflammation, and infection. In order to determine the exact cause, blood tests and imaging may be performed.
