Recently, an aunt often turned off the lights and brushed the short video to cause the eye "stroke" news on the hot search. Staying up late to watch dramas, hiding under the covers and playing with mobile phones before going to bed, are many people doing such things? Will you go blind?
There is a special reminder that winter is the high incidence of "eye stroke", in addition to staying up late for a long time, people who use their eyes excessively, people with high blood pressure, hyperlipidemia, hyperglycemia and other "three high" basic diseases, must pay special attention to their vision, once there is blurred vision, blackening in front of the eyes and other issues, must catch 90 minutes of golden first aid time!
According to reports, aunt Zhou of Jiangsu province suddenly lost sight in her right eye after getting up recently, and after the doctor's examination, it turned out that she had a "stroke" in the eye, and was told that this was related to her bad habit of often brushing short videos for a long time and brushing until one or two o'clock in the morning after turning off the lights at night.
What is "eye stroke"?
Jin Chenjin, chief physician of the Department of Ophthalmology of The Zhongshan Eye Center of Sun Yat-sen University, introduced that "eye stroke" is an ophthalmic emergency, which is menacing, and once the disease occurs, the golden treatment time is 90 minutes.
"Eye stroke" is a disease of ophthalmic artery blockage, when the blood vessel blockage causes ischemia and hypoxia, the patient will have symptoms, if it occurs in the central retinal artery, almost the entire fundus blood supply is gone, then the eye will be completely invisible; if it occurs in the branch artery, it will cause a certain range of visual field to be invisible or partially affected vision, because it is painless, often let the patient despise negligence, resulting in cell necrosis, then go to the hospital, it is difficult to save the damaged vision.
Sudden "stroke of the eye" case is not uncommon in the clinic, but because many patients do not understand this disease, often take it lightly, and when they go to the hospital, they have missed the golden treatment time, "the dead retinal nerve cells can not be resurrected, nor can they regenerate, once the macular central depression is affected and the visual impairment is permanent."
It's more common in middle-aged and elderly people, but these people should also be careful
"Stroke" is more common in middle-aged and elderly people, but it has been found in the clinic that "stroke" can occur at any age stage, and in recent years, there has also been a phenomenon of rejuvenation.
Jin Chenjin introduced that this disease has some high risk factors, such as long-term use of the eyes, emotional tension leading to the eyes in a state of overwork, smoking and other significant impact on blood vessels is a risk factor, hypertension, hyperlipidemia, hyperglycemia and other three high groups are the key prevention and control objects.
"In recent years, every year, I have encountered 2 or 3 cases of young people's unauthorized beauty and blindness, which makes people sigh." Jin Chenjin, chief physician, introduced that these young people in their twenties and thirties went to informal beauty institutions, and when injecting hyaluronic acid (also known as hyaluronic acid) or fat, there was a reflux situation, and these substances regurgitated from the ocular surface vein to the eye artery, resulting in blockage of the eye artery, and finally led to blindness of the eye, which was a pity that they could not be seen at a young age.
Hold on to 90 minutes of golden healing time
When the symptoms of "eye stroke" appear, such as high-risk people suddenly blurred eyes can not see clearly, after a while it is better, or blurred vision gradually completely invisible, etc., do not hesitate, should immediately go to the hospital for treatment, to keep 90 minutes of this golden treatment time.
"At this time, don't be stuck in finding an expert or waiting for work during the day to see it." Experts said that the decision-making of patients in the clinic often delays the timing of treatment, in fact, "stroke" as an ophthalmic emergency, not a difficult disease, the general ophthalmic emergency doctor can diagnose and treat, the emergency department also has the basic equipment to check the fundus to help quickly diagnose the diagnosis.
However, there is an atypical category of "eye strokes" that are very hidden. Jin Chenjin introduced that this kind of atypical "eye stroke" is initially a vein blockage, the symptoms may be blurred vision in the eyes, and the vision loss is not serious, such as the initial venous blockage, which is difficult to be found because the symptoms are not obvious. However, after the venous blockage is secondary to the blockage of the artery, there will be a sharp decline in vision or even blindness, which means that the "eye stroke" has really occurred, "want to intercept the signal before the attack, it is recommended that such patients add a fluorescent contrast on the basis of general fundus photography, you can immediately know the static artery blockage." ”
Elderly people with diabetes, hypertension and other diseases, such as sudden blackening, vision loss or temporary blindness, eye ripples and other phenomena, on the way to the hospital ophthalmology, you can take certain self-help measures:
If you take nitroglycerin, and massage the eyeballs on your own, press lightly for a few seconds and then suddenly release, and so on, so as to reduce intraocular pressure and increase retinal vascular perfusion.
Treatment can be done for different causes
At present, "stroke" is difficult to implement mechanical thrombosis like "stroke", because the blood vessels in the eye are very small, the thrombolytic effect is difficult to predict, so even if the treatment time is immediate, it is difficult to ensure that vision can be fully restored.
Jin Chenjin introduced that at present, the causes of "eye stroke" are multifaceted, and can be treated for different causes.
If it is caused by embolus blockage, the drug thrombolysis method can be taken;
If it is caused by inflammation, viral infection, autoimmune diseases and other reasons, it is also necessary to treat the corresponding cause.
If the 90-minute golden window is missed, aggressive treatment within 24 hours may also have a certain stop-loss effect, and within a week, it can be considered to cooperate with oxygen therapy to reduce the further damage of hypoxia to nerve cells and increase the hope of saving part of the vision.
Therefore, it is more important to strengthen the prevention and control of this disease.
Examination: These high-risk groups require regular medical examinations
For people who use their eyes for a long time, such as media practitioners, engineers, IT workers, long-term screen brushing enthusiasts, etc., we must pay attention to the combination of work and leisure, and do not make the eyes in a state of tension and high pressure for a long time; for the three high groups, we must do a good job in the treatment of basic diseases; usually life and rest should be regular, and the diet should not be too greasy.
It is important to strengthen the annual medical examination. "Fundus photography can see the blood flow of the fundus artery vein, if the blood vessel is narrow, or the color of the artery is white (more oil), it is easy to trigger the blockage, and it is important to detect these risk factors in time for prevention." Jin Chenjin said.
In addition, experts remind that for people with "stroke of eye", even if the vision of one eye is not preserved, it is necessary to review regularly, because there is a healthy contralateral eye, try to find out the cause of the "stroke" attack, on the one hand, to curb the disease, on the other hand, it is helpful for contralateral eye prevention. "Stroke of the eye" attack for about 3 months, there may be secondary neovascular glaucoma, resulting in eye pain and headache, seriously affecting the quality of life, timely detection and treatment can alleviate the condition, so it is important to ensure regular review.
Prevent "eye stroke" Pay attention to eye health
Youjun especially reminded that winter is the high incidence of "eye stroke", because the temperature difference between day and night is easy to cause vasoconstriction and spasm, making embolus easy to form and blocking "eye blood vessels". Therefore, it is also necessary to pay attention to basic prevention such as keeping warm and exercising moderately.
Yang Chengming, chief physician of the Department of Ophthalmology of Southern University of Science and Technology Hospital, put forward the following eye suggestions for people who have used electronic screen products for a long time.
1 Control eye time
Use your eyes for about an hour or so to go out for a walk and relax, about 5 minutes to 10 minutes and then come back to continue using your eyes;
2. Overlook
If the floor is relatively high or there is a balcony or window, you can also look out the window for about 1 minute to 2 minutes;
3. Control brightness and distance
Usually when looking at the mobile phone, try to adjust the brightness of the screen a little lower, and the distance from the screen is about 30 cm to 50 cm;
4. The posture should be correct
Lying in such a position is very unfavorable to the eyes;
5. Try to avoid looking at your phone in a dim environment
At night, try to have a backlight with your eyes, so it is better to use your eyes.
