What is ischemic optical neuropathy?
ischemic optical neuropathy is an eye disorder that is most commonly observed in people over 50 years of age. It is characterized by a slight to severe loss of vision, which is usually painless and worse in one eye than in the other. Visual problems occur when the optical nerve does not receive a stable supply of new oxygen -rich blood due to inflammation or damage in nearby blood vessels. Ischemic optical neuropathy may or may not be a sign of a very serious basic health problem called giant cellular arteritis, so it is important to see a doctor in the first signs of deteriorating visual problems to obtain an accurate diagnosis. Most patients are able to register at least part of their vision prescription medications.
Most cases of ischemic optical neuropathy are related to the problems with the front of the optical nerve, the part closest to the eye, which is also called an optical disk. The disk collects information from millions of small nerve endings in the eye and transmits the signals of the brain. In order to make a sprayOutside, it requires a constant supply of oxygenated blood. If the blood vessels are weak or damaged, the nerve is less effective in passing signals. As a result, the sharpness of vision and the perception of light is reduced.
The cause of ischemic optical neuropathy is not always clear. Many patients have a basic disease that increases the risk of blood vessel problems and optical disk damage such as diabetes, arthritis, high cholesterol, high blood pressure and heart disease. Problems occur when blood circulation is bad, leading to a sudden sharp drop in eye pressure and swelling of the optical disk. Giant cell arteritis is a rare but severe potential that induces inflammation of the blood vessels in the head and neck, including fine blood vessels.
Most cases that do not include arteritis are painless. VISPOZEMINE ions tend to proceed quickly, sometimes in a few days or evenDIN. Some people wake up from night sleep to find out they don't see well or at all from one eye. It is also common for a person to lose the ability to detect fine shades of color, depth and light of light. The vision can also be very spotted or blurred. If arteritis is present, a person may have other symptoms such as fever, headache and neck and fatigue.
Ophthalmologist can diagnose ischemic optical neuropathy by clinical examination. A specialized microscope is used to view optical disk and surrounding blood vessels to find symptoms of inflammation. If the problem is discovered, blood tests are required to confirm or exclude arteritis. The decision on treatment is taken on the basis of basic causes when they can be discovered.
ischemic optical neuropathy is usually treated with oral or injected steroids to alleviate acute inflammation. Basic factors such as diabetes or high cholesterol are treated appropriately by drugs or surgery. ArteRitis may require a very long course of anti -inflammatory drugs and drugs that suppress the immune system. The outlook may vary, but most people who receive quick treatment will start to see in a few days.
