The symptoms of an eye stroke usually don't include pain. The first and main symptom is usually a sudden loss of vision or change in vision in one eye that may include: Floaters and flashes. Blurred vision.
Eye Stroke Symptoms
The hallmark signs of eye stroke are sudden and painless vision loss or changes in vision -- like blurriness, floaters, a darkened area in your field of vision, decreased visual contrast, and light sensitivity -- in one eye. Although these symptoms usually come on quickly, they can appear gradually.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
If you notice a sudden increase in eye floaters, contact an eye specialist immediately — especially if you also see light flashes or lose your vision. These can be symptoms of an emergency that requires prompt attention.
Most people with eye stroke notice a loss of vision in one eye upon waking in the morning with no pain. Some people notice a dark area or shadow in their vision that affects the upper or lower half of their visual field. Other symptoms include loss of visual contrast and light sensitivity.
Stroke: Sometimes eye doctors can detect blood vessel blockages in the back of the eye, which pose a high stroke risk. A regular vision exam can help detect a stroke before it happens, especially in older individuals.
Floaters can be harmless and a normal sign of aging. However, if they increase or appear with light flashes or any vision loss, call your healthcare provider since it could indicate something more serious.
As long as eye floaters are not impairing your vision and are just a nuisance, you have no need to be concerned. However, if eye floaters are brought on suddenly accompanied by flashes of light, blurred vision, loss of peripheral vision, and an increase in the number of floaters, seek immediate medical attention.
What causes floaters? Floaters usually happen because of normal changes in your eyes. As you age, tiny strands of your vitreous (the gel-like fluid that fills your eye) stick together and cast shadows on your retina (the light-sensitive layer of tissue at the back of the eye). Those shadows appear as floaters.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
The signs and symptoms of a stroke often develop quickly. However, they can develop over hours or even days, such as when a transient ischemic attack (TIA) turns into a stroke. The type of symptoms depends on the type of stroke and the area of the brain that is affected.
A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
It is a mass compression on the optic nerve crossing. The result from these impairments is blurred vision, vision loss, and some have also claimed to have seen white spots in their field of view. Patients suffering from a brain aneurysm may also experience double vision.
Eye floaters and heart disease
An increase in floaters can occasionally indicate an eye condition called retinal vein occlusion, which is linked to heart disease. A vein behind the eye gets blocked (occluded) in this condition, causing a reduction in vision.
In most cases, the occasional eye floater or flash in your vision isn't something you need to worry about. This often happens as you age and it's very normal. However, if you start to notice a lot more floaters than you've experienced in the past or many flashes, you should call your doctor.
A large number of floaters can signal a hole or tear in the retina, which can lead to retinal detachment. Because there is no way to assess the extent of damage based on symptoms alone, the only way to know for sure is to see an ophthalmologist.
Eye floaters are very common. As a matter of fact, 7 out of 10 people will experience them at some time in their lives. Eye floaters are an ordinary part of the aging process because the clear substance inside the eye (vitreous gel) changes with age. When the vitreous gel shrinks or thickens, particles form in the gel.
High blood pressure and vision disturbance
Increased pressure in the eyes can damage the blood vessels and surrounding tissues over time, leading to various vision changes, including blurring, eye floaters and seeing double.
Most people become accustomed to floaters and they can ignore them, but there are some instances when you should not ignore floaters. It may be necessary to call your eye doctor if you notice an increase in eye floaters, eye pain, changes in peripheral vision or see flashes of light.
Can eye floaters fluctuate from day to day or throughout the day? Yes, they can vary in different light conditions and can appear more prominent against light backgrounds. Some people notice floaters more when they are tired or at the end of the day.
Strokes. Let's get back to those blood vessels in your retina. Detecting a theme here? Sometimes, especially in older patients, those blood vessels can exhibit blockages or clots that are visible during a dialed eye exam.
Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms.
Even if your vision can't be restored, always seek medical advice after an eye stroke, as you are at increased risk of a stroke in your brain.
