What is temporal pallor of optic nerve?
It refers to pallor of the optic disc which results from irreversible damage to the retinal ganglion cells and axons. The axons of the retinal ganglion cells make up the optic nerve and continue onto the optic chiasm, optic tract and up to the lateral geniculate body before they synapse.
What is temporal pallor?
• Altitudinal pallor is often observed in vascular disease such as anterior ischemic optic neuropathy. • Temporal pallor, as seen in our patient, is typical of optic neuritis, toxic/nutritional, and hereditary optic neuropathies.
What causes pallor of optic nerve?
Compressive Lesions That Cause Disc Pallor Compressive neuropathy by a mass lesion often can result in disc pallor and optic atrophy. Prolonged compression results in optic atrophy, which may present with pallor and/or cupping of the nerve head. Optociliary collateral vessels may be noted at the disc margin.
What is bilateral optic nerve atrophy?
Optic atrophy is a condition that affects the optic nerve, which carries impulses from the eye to the brain. (Atrophy means to waste away or deteriorate.) There is no effective treatment for this condition. Appointments 216.444.2020.
Is a pale optic nerve serious?
Underlying causes of pale optic nerves can range from benign to brain tumor, so the stakes are potentially high.
Why is temporal pallor used in optic discs?
It can be temporal or altitudinal disc pallor. Temporal pallor results due to involvement of the papillomacular bundle and commonly seen in toxic, nutritional optic neuropathy. NAION initially presents with disc swelling followed by sectoral disc pallor.
How do you treat a pale optic nerve?
Unfortunately, there is no treatment to reverse atrophy of the optic nerve; however, limiting further optic nerve damage (if possible) is the goal. For example, reduction of increased fluid pressure around the brain and spinal cord (hydrocephalus) may prevent further optic nerve damage.
Does optic atrophy show up on MRI?
[19] The diagnosis is based on opthalmoscopic findings. MRI reveals diffuse bilateral optic nerve atrophy.
What is pallor of the eye?
Optic atrophy is a sign and typically is noted as optic nerve pallor. This is the end stage of a process resulting in optic nerve damage. Because the optic nerve fiber layer is thinned or absent the disc margins appear sharp and the disc is pale, probably reflecting absence of small vessels in the disc head.
Is optic nerve atrophy a disability?
If your child is diagnosed with infantile bilateral optic atrophy, he or she will automatically qualify medically for Social Security disability under the compassionate allowances program.
What does “pale” optic nerve mean?
Then, what is a pale optic nerve? Optic atrophy, pallor of the optic nerve head, is a sign found in patients with visual loss due to pathology of the optic nerve or retinal ganglion cells. There are many causes. It refers to pallor of the optic disc which results from irreversible damage to the retinal ganglion cells and axons.
What are the causes of bilateral median nerve neuropathy?
Removal of pressure.
What is the difference between olfactory nerve and optic nerve?
Olfactory nerve The olfactory nerve is tested by asking the patient to recognize various odours. The right and left nerves can be tested separately by closing one nostril and putting the substance near the open nostril. Optic nerve and visual pathway Testing the optic nerve: To test the optic nerve first ask the patient if his vision is normal.
Does the optic nerve pass through the foramen ovale?
The optic foramen, the opening through which the optic nerve runs back into the brain and the large ophthalmic artery enters the orbit, is at the nasal side of the apex; the superior orbital fissure is a larger hole through which pass large veins and nerves.…. Click to see full answer.
