What is the difference between optic neuropathy and retinal artery occulsion?

Related issues. Optic neuropathy is a generic term referring to damage to the optic nerve from any cause including trauma, decreased blood flow, or genetic disease. Retinal artery occlusion is a blockage in the artery feeding the retina, which leads to damage or death of the retinal nervous tissue. A central retinal artery occlusion can cause an optic neuropathy.

What are the differences between ischaemic optic neuropathy and retinal artery occulsion?

Difficult to answer. If one distinguishes between anterior and posterior ischemic optic neuropathy this is easier to answer as the former is almost always caused by giant cell arteritis and treated with prednisone and the latter is due to systemic atherosclerosis. Acute central retinal artery occlusion may be caused by carotid occlusion or dissection or cardioembolic events. Treatment includes hyperbaric O2. Read more...
Location. Ischemia affecting the anterior optic nerve is due to occlusion of the short posterior ciliary arteries, whereas posterior ischemia is due to occlusion of pial vessels arising from the ophthalmic artery. A retinal artery occlusion is due to blockage of an arteriole inside the eyeball, usually from emboli. Both are serious causes of loss of vision with near similar prognosis but different treatment.

Can you please tell me how ischaemic optic neuropathy and retinal artery occulsion differ?

Nerve vs. artery . Arterial occlusion generally from embolus, inflammatory, which affects the inner retinal lining of the eye. Ischemic optic neuropathy is due to blockage of the blood flow to the optic nerve (anterior ciliary arteries or posterior nutritive). Other causes can be from compression form tumors or inflammation as in giant cell arteritis. Read more...

Please help! What is the difference between optic neuropathy, and optic neuritis?

General terms. Optic neuropathy is the general term for any condition that affects the transmission or appearance of the optic nerve, the main nerve carrying visual information from the eye to the brain. Optic neuritis is a subset of neuropathy, referring to inflammatory conditions of the optic nerve. Read more...

Can bilateral optic neuropathy really not be treated & if it's in 1 eye will it go to the other eye?

See below. Damage to vision from optic neuropathy can not be undone. The treatment (what will allow it to not get worse) depends on the exact cause. Also, whether optic neuropathy becomes bilateral (both eyes) or not depends on the cause. You need to see your ophthalmologist and ask these questions. Read more...

Can you tell me about lebers hereditary optic neuropathy in one eye and not have it move to the other eye?

Leber's HON. Leber's hereditary optic neuropathy is felt to be due to a defect in mitochondrial dna. If it occurs in one eye, it almost always eventually shows up in the other. Some genetic testing can be performed if the diagnosis is in doubt. Read more...
