What Are the Symptoms of an Eye Stroke? - Oren Zarif - Eye Stroke

If you've suddenly noticed a decrease in your vision, you may have suffered an eye stroke. The stroke typically leads to a temporary loss of vision but may also cause other complications. While you should seek medical attention as soon as possible, you should also be aware of the symptoms of an eye stroke. Some common symptoms of eye stroke include decreased vision, blurred or double vision, and loss of peripheral vision. Read on to learn more about these conditions and how to identify them.

Among the most common types of eye stroke are RVO and AION. RVO occurs when a vein becomes blocked, preventing blood from flowing through it. These venous conditions can also cause floaters, which are merely small gray spots in your field of vision caused by blood and other fluid leakage. If the condition is left untreated, the retina may become detached and result in irreversible vision loss. Despite the possibility of permanent damage, the symptoms of an eye stroke are usually painless.

In most cases, eye stroke results from a blockage in one or both of the arteries and veins supplying the retina with oxygen and nutrients. Because these arteries and veins can become blocked, the retina loses its ability to get oxygen, resulting in vision loss or weakened vision. Without proper treatment, a patient can lose their vision and even become blind. It's important to seek medical attention immediately if you suspect an eye stroke.

Some patients may receive medications to dissolve clots or reduce pressure in the eye. In some cases, medications to treat diabetes, high blood pressure, or heart disease may also be prescribed. Treatment of any of these conditions will depend on the underlying disease. However, the earlier you receive medical care, the more likely you are to be able to save your sight. Your doctor may recommend routine blood pressure checks and cholesterol levels and discuss other potential risk factors with you.

While a blood clot can result in an eye stroke, the blockage in an artery can also be caused by cholesterol. In some cases, the blockage may break down on its own but it can cause substantial damage if left untreated. If you've had a history of strokes or other health issues, you are at a higher risk for eye stroke. If you've experienced a stroke, it is imperative to seek medical attention immediately.

An eye stroke must be treated immediately, as delayed treatment may lead to a more serious condition. Symptoms of eye stroke can include sudden loss of vision, as well as increased stroke risk. Eye stroke is often treated by doctors at Mount Sinai Emergency Departments. Treatment must be administered within six to twelve hours after the stroke is diagnosed. A retina specialist at Mount Sinai can diagnose a retinal artery occlusion and direct you to a qualified eye doctor.

Another cause of eye stroke is a blockage in the retinal artery. These blood vessels carry nutrients and oxygen to every part of your body. When this blood flow is cut off, the body part can suffer substantial damage. When this happens to your retina, it can affect your vision permanently, and even result in blindness. So if you think you might be experiencing an eye stroke, it's imperative to get medical treatment as soon as possible.

In addition to visual changes, another symptom of eye stroke is sudden, painless vision loss. The symptoms usually appear quickly, but sometimes they can progress slowly. To diagnose a stroke, an ophthalmologist must examine your eyes and take a fundus photo. A fundus photo is a specialized test that allows a doctor to see the internal components of the eye, including the retina and optic nerve. You should see a doctor as soon as possible in an emergency room.

Unlike a true stroke, a nonarteritic anterior ischemic optic neuropathy (NAION) happens when the blood vessels in the eye are not sufficiently perfused. The optic nerve suffers from a lack of blood. Without treatment, vision loss can become permanent. The eye doctor will assess the optic nerve to ensure that it's healthy. This test is known as tonometry. Once the diagnosis is made, treatment will be focused on restoring vision.

TPA therapy is a clot-busting drug used to treat eye stroke. It is important to start treatment within six to twelve hours of the stroke. The earlier the blood flow is restored, the better the chance of saving the patient's vision. In the meantime, the New York Eye Institute (NYEE) is actively researching TPA for the treatment of eye stroke. These findings suggest that TPA treatment may be an important component of primary prevention for the disease.
