CRION is a rare disease that causes inflammation of the eye nerve, causing severe eye pain and progressive vision loss, the diagnosis of which is defined by the ophthalmologist when these symptoms are not accompanied by other diseases, such as sarcoidosis, which can justify optic nerve degeneration and vision loss.
Generally, the CRION patient has periods of worsening symptoms, in seizures, which last about 10 days and then disappear, and may recur within a few weeks or months; however, vision loss doesn’t usually go away even after the crisis is over.
- CRION does not heal.
- But seizures can be treated with corticosteroids.
- So as not to aggravate the injury.
- So it is recommended to go to the hospital immediately when the pain begins.
The main symptoms of recurrent chronic inflammatory optic neuropathy include:
Symptoms can appear in one eye or affect both eyes without visible changes in the eye, such as redness or swelling, as the disease affects the optic nerve at the back of the eye.
Treatment of recurrent chronic inflammatory optic neuropathic disease should be guided by an ophthalmologist and is usually done by injecting corticosteroids, such as dexamethasone or hydrocortisone, directly into the vein to prevent worsening vision and relieve pain caused by the disease.
In addition, your doctor may recommend taking a daily dose of corticosteroid tablets to increase the symptom-free period and prevent gradual deterioration of vision.
The diagnosis of recurrent chronic inflammatory optic neuropathic disease is usually made by an ophthalmologist by looking at the patient’s symptoms and medical history.
However, in some cases, diagnostic tests such as MRI or lumbar puncture may also be necessary to eliminate the other possibility of diseases that cause vision loss, eye pain or feeling increased pressure, thus confirming the diagnosis of CRION.
