If your eyes suddenly go dark, it may be a sign of blindness due to a stroke! The best rescue time is only 1.5 hours...

You must be tired after studying and working all day. If you are tired, why not go to bed early?

Sleep? Impossible. The night life has just begun. If I don’t play with my phone before going to bed, it’s like eating without soup. I always feel like something is missing.

There are three hardest things to quit in this world: staying up late, playing with mobile phones, and staying up late playing with mobile phones.

Not long ago, Metropolis Express reported that a Ningbo man suddenly found his right eye blurred while at work. He could not see the computer screen clearly and could only see the fingers placed in front of his eyes. He immediately went to the hospital for treatment and was diagnosed with an ocular stroke.

This is the first time I've heard the term "eye stroke"

We have all heard of brain stroke, but do you know what eye stroke is?

Eye stroke is a figurative term. It is a serious, acute, blinding eye disease usually caused by blockage of the retinal artery or vein. It can cause decreased vision, blurred vision, difficulty focusing, partial darkening of the visual field, and even permanent blindness in severe cases.

Specifically, our arterial blood flows from the heart to the eyes. Once the ophthalmic artery is blocked, the retinal artery will suffer from ischemia and hypoxia, leading to edema. If not treated in time, the retinal cells will completely die within 53 hours, resulting in permanent blindness.

Unlike arteries, venous blood flows from our eyes back to the heart. Once the veins are blocked, the blood cannot flow away from the eyes, which will manifest as bleeding. Some small black shadows will appear at the bleeding site, and it will also cause edema of the fundus cells. Although it is not more critical than retinal artery blockage, it has very serious complications, namely neovascular glaucoma. In severe cases, even the eyeball may not be saved.

There is a golden time for rescue of cerebral stroke, and similarly, there is a golden time for rescue of eye stroke.

If the eye is ischemic for more than 1.5 hours, the retinal photoreceptors will be irreparably damaged. If the eye is ischemic for more than 2 hours, the retina will atrophy and vision will be difficult to recover.

Who is prone to eye stroke?

Eye stroke generally occurs more frequently in the elderly and those suffering from hypertension, hyperlipidemia, and hyperglycemia. However, the population suffering from eye stroke is getting younger and younger, and the reason for this has a lot to do with our current lifestyle habits.

Looking at electronic screens such as mobile phones, iPads, and televisions in a dark environment for a long time, overusing the eyes, staying up late, frequent drinking, smoking, and emotional instability may all lead to sudden eye stroke.

I don't want an eye stroke, what should I pay attention to?

When it comes to eye stroke, prevention is the main thing, and treatment is secondary. Good eye habits are important:

1. Perform eye exercises carefully and properly, maintain correct reading and writing posture, and avoid reading, writing or working in strong light or dark environments.

2. Try to reduce the number of times you use eye drops. Although eye drops can help us temporarily relieve fatigue and reduce red eye symptoms, they only treat the symptoms and not the root cause. Inflammation will still exist, and repeated use may be counterproductive.

3. Don’t rub your eyes with your hands, because there are many invisible bacteria on our hands. Rubbing your eyes with your hands will bring bacteria into your eyes and may cause eye inflammation.

4. Avoid overusing your eyes. Staring at mobile phones, computers and other electronic devices for a long time will cause our eyes to become dry and sore, and will also affect our vision. In more serious cases, it may even cause glaucoma. For people who overuse their eyes, such as programmers and media workers, it is important to pay attention to the combination of work and rest. After working for a period of time, look up and look at the scenery in the distance to relax your eyes and avoid long-term high-pressure conditions for the eyes.

5. For people with three highs, they must follow the doctor's advice and treat the underlying diseases. It is important to develop good work and rest habits, eat light food instead of greasy food, exercise actively every day, play less with mobile phones, and go to bed early.

Regardless of which group we belong to, we should all pay attention to eye health and have regular physical examinations every year.

Fundus photography can show the blood flow in our retinal arteries and veins, and can intuitively understand the health level of the retinal tissue. When our fundus is diseased, the structure, shape, and color of the vitreous body and retina at the back of our eyeball will change accordingly. Only by discovering these risk factors in time can we do better prevention.

It is worth noting that eye stroke may have precursors. If you sometimes suddenly see black in front of your eyes, and then it clears up after a while, or if there are intermittent black shadows in front of your eyes, you must not be careless, please go to the hospital for a check-up in time to prevent it from happening.

Eyes are the windows to the soul. In order to protect our young hearts from being hurt, let’s start by protecting our eyes. Play less with mobile phones and stay up late less. After all, we only have one pair of eyes, but we can have countless mobile phones!
