Can radiation damage optic nerve?

Radiation-induced optic neuropathy (RION) is a devastating late complication of radiotherapy to the anterior visual pathway resulting in acute, profound, irreversible visual loss. It is thought to be a result of radiation necrosis of the anterior visual pathway.

What is the likely outcome of optic neuritis?

In people with optic neuritis, the risk of developing multiple sclerosis after one episode of optic neuritis is about 50% over a lifetime. Your risk of developing multiple sclerosis after optic neuritis increases further if an MRI scan shows lesions on your brain.

Can radiotherapy cause blindness?

RION is a devastating late complication affecting the anterior visual pathway in NPC patients following radiotherapy. Despite this being a rare complication, the disabling damage to vision severely affects the patients’ quality of life and usually results in profound irreversible visual loss.

What does radiation do to your eyes?

Possible side effects of radiation therapy The main concern with radiation therapy is damage to parts of the eye, leading to problems such as blurry vision, dry eye, cataracts, retinal detachment, glaucoma (increased pressure inside the eye), loss of eye lashes, problems with tear ducts, or bleeding into the eye.

Can stress cause optic neuritis?

In fact, continuous stress and elevated cortisol levels negatively impact the eye and brain due to autonomous nervous system (sympathetic) imbalance and vascular dysregulation; hence stress may also be one of the major causes of visual system diseases such as glaucoma and optic neuropathy.

How can I protect my eyes from radiation?
