What Is Optic Atrophy? The optic nerve is a bundle of nerve fibers that carry images from your retina to your brain. Each fiber carries a part of the visual information to the brain. If these nerve fibers become damaged, the brain doesn't receive all of this vision information and sight becomes blurred. Optic atrophy means the loss of some or most of the nerve fibers in the optic nerve. The effects range from visual change to severe visual loss.
Background. Optic atrophy is the final common morphologic endpoint of any disease process that causes axon degeneration in the retinogeniculate pathway. Clinically, optic atrophy manifests as changes in the color and the structure of the optic disc associated with variable degrees of visual dysfunction.ressure or traction atrophy is observed in diseases such as glaucoma and papilledema. Postinflammatory atrophy. Postinflammatory atrophy is observed in diseases such as optic neuritis, perineuritis secondary to inflammation of the meninges, and sinus and orbital cellulites.
