An eye stroke, also known as retinal artery occlusion, happens when blood flow is interrupted or significantly reduced in the retina. The retina’s located at the back of the eye.
Basically, an eye stroke is similar to a stroke in the brain, except it affects the eye. When blood supply to the retina is cut off, the retina can’t do its job properly, which causes all sorts of problems, leading to damage. So, what exactly causes an eye stroke, what are the signs, and what can you do about it?
Causes of Eye Stroke
The eyes like other parts of your body rely on a steady supply of oxygen-rich blood to function. Eye strokes happen when the blood supply is cut off. One of the main reasons for this is when a vessel in the back of the eye gets blocked.
An eye stroke seriously messes with the signals sent from the eye to the brain. These signals rely on the tiny blood vessels the small and big arteries that move blood to and from the heart. This blood, by the way, is super important for seeing. When there’s a sudden blockage in the eye’s blood supply, it can lead to blindness.
An eye stroke can occur when blood flow is blocked, caused by a blood clot. This can block the arteries in your eye. I remember my grandfather who had high cholesterol levels, was at a higher risk.
Thinking about my grandfather, it made me think a lot about how modern diets affect our eye health. We’re so focused on preventing the obvious illnesses we often overlook how nutrition supports our eyesight. What are some key nutrients that are essential for maintaining healthy vision? How can we easily incorporate them into our everyday meals?
Types of Eye Stroke
There are different kinds of eye strokes, depending on which blood vessel is affected – whether it’s an artery or a vein.
- Central Retinal Vein Occlusion (CRVO): A blockage in the main vein that drains blood from the retina.
- Central Retinal Artery Occlusion (CRAO): A blockage in the main artery that supplies blood to the retina.
- Branch Retinal Vein Occlusion (BRVO): A blockage in a smaller branch of the retinal vein.
- Branch Retinal Artery Occlusion (BRAO): A blockage in a smaller branch of the retinal artery.
Who Is Most at Risk of an Eye Stroke?
Some folks are more likely than others to experience an eye stroke, including:
- People with high blood pressure.
- People with high cholesterol.
- People with high levels of bad cholesterol or high triglycerides.
- People who’ve had a heart attack or stroke before.
- People who suffer from migraines.
- People with heart disease.
- People with diabetes.
- People with glaucoma, which affects the optic nerve responsible for transmitting information from the eye to the brain.
- Older adults, especially men.
Symptoms of Eye Stroke
Symptoms of an eye stroke can show up fast – like, within hours or days. Or sometimes, it happens suddenly. You might experience:
- Blurry vision, with spots or floating shapes in one or both eyes. Some folks describe it like seeing cobwebs or floaters.
- Pain or pressure in the eye which, honestly isn’t usually part of the deal, so that could be something else.
- Seeing dark spots in one or both eyes.
- Complete vision loss that hits you all at once.
If you’re experiencing any of these symptoms, see a doctor ASAP! The faster you act, the better your chances of saving your eyesight.
Complications of Eye Stroke
You can recover from an eye stroke, but there can be complications. Especially if you don’t get the treatment you need in a timely manner. Some common complications include:
- Permanent vision loss.
- Neovascular glaucoma, where new blood vessels grow and cause a buildup of fluids and proteins, in the front part of the eye. This can really mess with your sight.
- New blood vessel growth in the retina which can lead to bleeding and glaucoma.
- Increased pressure inside the eye due to new blood vessel formation.
Diagnosing an Eye Stroke
To figure out if you’ve had an eye stroke, doctors will usually do a bunch of tests to look at the back of your eye, including:
- Optical Coherence Tomography (OCT): This test can show damage to the retina.
- Eye dilation with drops, so they can see the retina better.
- Fluorescein Angiography: This involves injecting a dye into your arm to light up the blood vessels in your eye so they can see any blockages or other problems.
- Checking the pressure inside your eye.
- Examining the front part of your eye using drops and a special microscope to look inside.
- Vision tests, like reading eye charts and checking your peripheral vision.
Treatment for Eye Stroke
There are a few treatment options for an eye stroke, and they’re mostly aimed at minimizing damage and improving blood flow to the retina. Treatment options include:
- Medications to dissolve blood clots and improve blood flow to the eye. These can help open up the blocked blood vessels and allow blood to flow more freely to the retina.
- Managing other health conditions, like diabetes, heart disease, and high cholesterol.
- Laser treatments if the need arises.
Ways to Prevent Eye Stroke
These tips might help you prevent an eye stroke:
- Get your eyes checked regularly – especially if you are at risk.
- Get some exercise regularly, aiming for at least 30 minutes most days of the week.
- Eat a healthy diet, lots of fruits, veggies, and healthy fats.
- Don’t smoke.
Key takeaways
- An eye stroke is a serious condition that can lead to permanent vision loss if left untreated.
- People with certain health conditions, like high blood pressure and diabetes, are at higher risk of experiencing an eye stroke.
- Prevention is key, so make sure to get regular eye exams, exercise, eat a healthy diet, and avoid smoking.
FAQ, Myth & Facts
Can an eye stroke cause blindness?
Yes, if left untreated, an eye stroke can lead to significant and even permanent vision loss.
Is an eye stroke the same as a regular stroke?
No, while both involve a disruption of blood flow, a regular stroke affects the brain, whereas an eye stroke affects the retina.
Are there any warning signs of an eye stroke?
Sometimes, but not always. Sudden blurred vision or vision loss can be a warning sign, but it’s not always the case. It’s crucial to see a doctor if you notice any sudden changes in your vision.
Myth: Eye strokes only happen to older people.
Fact: While older adults are more at risk, eye strokes can happen to anyone, especially those with certain medical conditions.
I had an incident last year that was quite alarming. I suddenly lost vision in one eye. After a whirl wind of tests, the doctor determined it was an eye stroke. The recovery has been slow, and I still have some blind spots, but I’m grateful I sought help immediately. It made all the difference.
My dad experienced sudden vision loss and it turned out to be an eye stroke. We learned so much about the importance of managing his blood pressure and cholesterol to prevent further incidents. It’s been a wake-up call for the whole family to prioritize health.
I’ve always taken my eyesight for granted until I started experiencing blurry vision and floaters. After seeing a specialist, I found out I had an eye stroke. Now, I’m on medication and making lifestyle changes, like eating healthier and exercising regularly. It’s been a journey, but I’m determined to protect my vision.
Thinking about my grandfather, you know, this whole thing has made me want to get my eyes checked – it’s just one of those things we put off, isn’t it? And maybe, just maybe, swap that burger for a salad sometimes. Our health, and our vision, is truly worth it.
