Eye Stroke - Causes and Treatment - Oren Zarif - Eye Stroke
An eye stroke is an emergency situation in which blood flow to the retina is blocked. The retina contains arteries from the heart and retinal cells require blood flow to get enough oxygen to stay alive. When this blood flow is blocked, the retinal cells begin to die and can damage vision permanently if not treated. The causes of eye stroke can range from a blood clot to fatty plaque that have accumulated over time. A medical emergency is vital in order to protect your vision.

There are three major types of eye stroke. There are two types of occlusion: central retinal vein occlusion and branch retinal vein occlusion. When these arteries are obstructed, fluids leak into the retina, making the eye swell. The fluids block the blood flow to the retina, making it hard for it to receive oxygen and nutrients. In the case of an eye stroke, the vision can be temporarily lost, but the symptoms of the condition are very serious and may result in permanent vision loss.

When eye stroke occurs, it typically comes with little warning. Most people with a stroke experience a loss of vision in a single eye and the vision will get worse over time. Fortunately, eye stroke rarely causes pain. Some people may notice darkened patches in their field of vision or loss of peripheral vision or visual contrast. They may also experience light sensitivity. In less severe cases, the retinal artery can be occluded and restore 80% of vision.

Treatment for eye stroke depends on the type of clot and the underlying disease. Depending on the symptoms and cause of the stroke, patients may be treated with medications that act as neuroprotectors. If early treatment is not possible, treatments like laser treatments or blood pressure-lowering medications can help save sight. But, treatment isn't complete without the appropriate testing and treatment. While the early treatment is crucial, a patient should have regular follow-up visits with a physician to ensure the condition is not worse.

The treatment for eye stroke includes drugs that dissolve clots and decrease pressure in the eyes. A doctor can also reduce pressure in the eye by inserting a needle into it and withdrawing fluid. Occasionally, breathing into a paper bag helps reduce pressure in the eye. It also increases carbon dioxide in the blood, which helps to lower pressure. However, it should be noted that eye stroke victims usually have other cardiovascular problems. If these conditions are present, patients may need to take blood thinners to reduce the risk of future strokes.

Emergency care for eye stroke is critical. Patients must seek medical treatment immediately, as even the smallest delay in treatment can result in irreversible vision loss. Emergency departments of Mount Sinai Health System are equipped with high-resolution imaging technology. A team of retina specialists and stroke experts work closely with emergency room physicians to ensure the patient receives proper care. A physician will immediately determine if you are suffering from retinal artery occlusion or a clot in the eye. If the eye is swollen or red, a clot-dissolving drug is administered.

If you notice that your vision has gone suddenly, see an expert as soon as possible. A doctor may perform tests or massage your eye and administer medications to relieve pressure. If you don't receive medical care within 24 hours, the stroke is already too advanced. You are at increased risk of a stroke in your brain. If you experience an eye stroke, seek immediate medical help and get a referral to a specialist. medicul eye stroke patients to avoid future problems.

There are several risk factors for developing an eye stroke. One of the most significant is having a history of heart disease. Studies show that up to 64 percent of those with eye stroke also had a new heart disease risk factor. High cholesterol is one of the leading risk factors for eye stroke. Depending on the type of stroke and the success of treatment, the long-term outlook for an eye stroke survivor varies. In addition to the risk of stroke, people with eye stroke may suffer significant vision loss.

The eyes need oxygen-rich blood flow to function properly. The retina contains nerves that send visual signals to the brain. A blockage in the blood vessels in the retina can severely damage your vision, and can lead to blindness. Thankfully, there are treatments for eye stroke. In the meantime, it's important to quit smoking. So, if you've suffered an eye stroke, seek medical attention immediately. The sooner you start the treatment, the better.
