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.
