What symptoms might occur with optic nerve damage? Any intrinsic or extrinsic compression anywhere along the optic nerve can produce compressive optic neuropathy (CON). For this reason, the condition only affects one eye at a time.
When MS attacks the optic nerve, it slows down the speed at which an image reaches the brain, resulting in vision distortion and vision loss. It is usually bilateral and affects both eyes.
Optic neuritis usually affects one eye.
Eleven cases were treated by surgical decompression of the optic canal and 22 cases were followed by medical treatment. Diabetes and Nerve Damage. When the optic nerve becomes damaged, this visual information is not fully transmitted, so the brain does not receive a complete picture. Direct injury is the result of penetrating eye trauma, seen frequently with orbital fractures. Most eye doctors treat if pressures are consistently higher than 28-30 mm Hg because of the high risk of optic nerve damage.
Although its signs and symptoms vary, this condition is traditionally defined by three characteristic features: underdevelopment (hypoplasia) of the optic nerves, abnormal formation of structures along the midline of the brain, and pituitary hypoplasia.

The clinical presentation is determined by the size, location, and extent of the tumor, but 90% of the lesions are symptomatic by the second decade. Optic neuritis is frequently associated with multiple sclerosis. No loss of function : Minimal optic nerve damage seen in early glaucoma is a structural change with or without visual field loss, depending on how the nerve is structurally changed. Optic nerve degeneration related to glaucoma may cause an effect called optic nerve cupping. Optic Neuritis . Damage to an optic nerve can cause vision loss. Optic nerve atrophy is the death of a portion of these fibers, leading to blurry or dim vision, side vision loss and altered color vision.
Examination must be done to differentiate between effects of optic nerve damage versus damage to non-nerve related areas to the visual system. For example: Open-angle glaucoma Patchy blind spots in your side (peripheral) or central vision, frequently in both eyes Tunnel vision in the advanced stages Acute angle-closure glaucoma Severe headache Eye pain Nausea and vomiting Blurred vision Seeing flashing or flickering lights when moving the eyes.
