Eye Stroke Diagnosis - Oren Zarif - Eye Stroke
There are several ways to diagnose eye stroke, including a blood test and an imaging study. Noninvasive imaging studies, such as optical coherence tomography (OCT), use light waves to create detailed images of the eye. Fluorescein angiography uses a fluorescent dye to highlight vascular structure in the eye. Blood tests can also be helpful in diagnosing the underlying cause of the eye stroke. The sooner treatment begins, the better the chances of saving the patient's vision.

People with eye stroke generally experience little warning, noticing a loss of vision in one eye upon waking. As the symptoms worsen, they often do not feel any pain. Some may notice darkened areas in their field of vision or a decreased visual contrast. Others may experience light sensitivity. If there are smaller blood vessels in the retina, the condition is known as branch retinal vein occlusion. The result is distorted vision or reduced vision.

The hallmark symptom of eye stroke is sudden and painless vision loss. It may occur suddenly or slowly. To diagnose eye stroke, your doctor will conduct a thorough eye exam and use imaging devices to see what's going on inside the eye. Fluorescein angiography highlights damaged blood vessels in the retina. Fluorescein angiography can be performed using advanced optometric imaging equipment. This type of imaging helps your doctor determine the cause of the stroke and determine how to treat it.

The most common type of eye stroke is retinal vein occlusion (RVO), which is caused by an obstructed blood vessel in the eye. A blood clot or plaque can block the artery or vein. Sometimes nearby artherosclerotic arteries can compress the veins. If your doctor suspects RVO, they may recommend a brain stroke test. AION usually causes permanent vision loss, while NAOIN is associated with an array of factors.

If you suddenly lose vision and experience double or triple vision, you should see an eye doctor right away. Even though the condition may be painless, it is still a sign of a larger problem. During the first week or two after an eye stroke, you may not be aware that you've had a stroke. Your doctor may use medications to reduce the pressure in your eye. But if you don't seek medical help immediately, your chances of a brain stroke are much higher.

Treatment of eye stroke involves medication that breaks up the clot and reduces pressure in the eye. Another treatment involves removing fluid from the eye and lowering pressure inside the eye. In many cases, people with eye stroke also suffer from other health conditions. High blood pressure or high cholesterol are two major risk factors. As such, it is critical to regularly see your doctor for regular physicals. If you're overweight, you may be at greater risk of an eye stroke than you think.

Some types of eye stroke can be painful or even life threatening. They can be caused by a blockage of the retinal veins or artery. When a blockage occurs in the main vein, the blood flow will be reduced, preventing oxygen and nutrients from reaching the retina. As a result, you may experience floaters, which appear as small gray spots in your field of vision. However, an eye stroke is usually asymptomatic. If you have symptoms, contact your doctor as soon as possible.

When you have severe blurred vision or loss of vision, it's important to visit the Emergency Room immediately. A temporary loss of vision may be caused by the retina detaching. If left untreated, vision loss may result in permanent damage. In either case, treatment aims to restore vision. In some cases, eye stroke can be treated. However, if a stroke does occur, the patient will need to follow up with their doctor for a year or longer.

Other health conditions may also contribute to the occurrence of an eye stroke. Keeping your blood pressure, glucose, and cholesterol levels within optimal levels can help prevent eye stroke. Regular exercise and eating heart-healthy foods can also reduce the risk of retinal artery occlusion. Smoking also increases the risk of stroke and should be quit gradually. Finally, regular eye examinations are important to avoid eye stroke and to prevent further damage. Even the smallest changes can have a huge impact on your health.
