Does high blood pressure affect the fundus? How much damage does high blood pressure do to the fundu

Hypertension may have an impact on the fundus, so fundus disease is a complication of hypertension, provided that the hypertension has been suffered for a long enough time and the blood pressure is not well controlled, then this will cause some complications, one of which is the complication of the fundus. Then the changes in the fundus caused by hypertension are mainly the changes in the blood vessels and arteries of the fundus. In the early stage, there is arteriosclerosis and stiffness, and in the later stage, there may be plaque, stenosis, and even bleeding, which will have a certain impact on the blood vessels, and will also have a certain impact on the vision and the function of the eye itself.

Therefore, for the prevention of fundus diseases, it is very important to control blood pressure, and use reasonable antihypertensive drugs to achieve a more reasonable blood pressure fluctuation space. Regular fundus examination is also a necessary physical examination for patients with high blood pressure.

Hypertension is a very common cardiovascular disease, hypertension has become an "invisible killer" of human health, when caused by such factors, there will generally be no different discomfort in the early stage of hypertension, and some mild symptoms will be mistaken for bad habits, as well as other types of diseases. In particular, when high blood pressure occurs, it may also affect people's eyesight, which is really difficult to prevent. Let's take a look.

Effects of high blood pressure on the eye.

1. Fundus hemorrhage.

The location of the eyes, the brain, and any area of the body in the body, usually surrounded by arteries and veins throughout the body. If you suffer from high blood pressure for a long time, it usually leads to atherosclerosis in the arteries, which can easily lead to blockage of the arteries. The arterial tube is located above the venous vessel, and when the artery is blocked, it will severely compress the venous vessel.

The blood in the veins is blocked for a long time and cannot flow back, resulting in local bleeding, and some of the blood in the veins, because of the blockage, will find another pipe to enter the retina, resulting in retinal hemorrhage. If there is too much bleeding, it will flow into the vitreous of the eye, causing bleeding in the fundus, causing blurred vision and blindness.

Retinal artery embolization.

One of the more serious diseases in ophthalmology is the blockage of the retinal artery of the eye. In particular, patients with high blood pressure have greater mood swings, and this disease can cause people to lose their sight in a few seconds. This is because the retina is a part of the brain tissue, and if you are deprived of oxygen for too long, it will degenerate and cannot recover, resulting in blindness.

If you have this disease, you should detect it early**, and it is best to rush to the hospital within an hour**. Because as long as the hospital diagnoses the embolism of the retinal artery, it can actively reduce intraocular pressure, dilate blood vessels, inhale oxygen and other certain rescue measures, which can dredge the blood vessels in the eye in the shortest time and help restore vision. If you go for more than 2 hours and then go to the rescue, it will be difficult to restore the vision of the eye.

Hello friends, generally speaking, high blood pressure does not affect the fundus, but when the blood pressure is very high, it can affect the fundus.

Vary. It is recommended to keep your blood pressure under control as much as possible.

Having high blood pressure can cause definite fundus lesions. Hypertension is a long-term chronic disease, which will have a definite impact on the arteries and blood vessels of the surrounding organs, the most common is to cause the hardening of the blood vessels, and the fundus will affect the blood vessels of the fundus, first there will be arteriosclerosis of the fundus, and then bleeding and exudation may occur, which will lead to unclear vision and decreased vision in patients with high blood pressure.

Hypertension is a common disease in internal medicine, and it will also have a certain impact on the eyes, for example, long-term hypertension may cause hypertensive retinopathy, the main manifestations are the thinning of the blood vessels in the fundus, poor blood flow, patchy bleeding, exudation, etc., and the risk of ischemic optic neuropathy in hypertensive patients is also increased.

Complications of high blood pressure, as the course of the disease progresses, the continuous increase in blood pressure will cause changes in the heart, brain, kidneys and fundus, because we know that the fundus contains the fundus artery, so the blood pressure will also increase, which will cause changes in the fundus artery, and even fundus hemorrhage.

For severe hypertension, it will also affect the fundus, once there is a problem with the fundus, go to the hospital for examination as soon as possible, so that it is easier to be more timely than timely.

Yes, high blood pressure can cause vasoconstriction in the fundus and may also cause retinal detachment.

Hello, long-term hypertension causes arteriosclerosis of the blood vessels, which can affect the vascular lesions of the fundus.

If you have high blood pressure, if you are not usually active, or if you usually eat irregular diet, or often eat greasy things or antihypertensive drugs, eat and stop, and some complications will occur after a long time, such as fundus bleeding.

Does high blood pressure affect fundus hypertension? It will affect the fundus, so it will affect the fundus again and again.

Hello. High blood pressure can cause fundus lesions.

Be sure to keep your blood pressure under control.

Blood pressure medication must be taken on time.

Don't take it lightly.

Generally, high blood pressure and diabetes may affect the fundus of the eyes if not treated in time.

Hypertensive retinopathy. Chronic hypertension is usually asymptomatic and presents primarily with binocular and extensive or localized narrowing of the retinal arteries. Acute (malignant) hypertensive retinopathy may cause vision loss. Xi'an Aier Ophthalmology Wang Lili.

The incidence of hypertension in life is relatively high, according to statistics, there are 100 million people suffering from hypertension in China. In real life, many patients are almost ignorant of hypertension, and even if the symptoms occur, they do not take the best plan, which will eventually lead to serious complications due to aggravation of the condition, so what is the damage to the eyes after the patient has high blood pressure? Here are the most common harms of high blood pressure.

Hypertension mainly refers to a significant increase in diastolic blood pressure and systolic blood pressure, which can be divided into three levels according to the type of disease, the higher the level, the greater the harm, and the common hazards include the following 4 kinds.

Clause. 1. Damage to the eyes. After the patient develops hypertension, if antihypertensive drugs are not taken in time**, it will lead to fundus lesions, mainly characterized by decreased vision, fundus hemorrhage, and in severe cases, blindness will also be induced.

Clause. 2. Damage to the kidneys. If blood pressure is persistently elevated, this can lead to increased glomerular pressure and glomerular damage, which can eventually lead to decreased kidney function or kidney failure.

Clause. 3. Harm to the heart. According to statistics, 30% of patients will have ventricular hypertrophy after hypertension, and 50% of patients will have myocardial infarction.

Clause. Fourth, it causes damage to the brain. After the patient develops hypertension, if the blood pressure fluctuates frequently, it will cause the blood vessel flow rate to slow down and easily cause brain diseases, such as stroke, cerebral hemorrhage, cerebral infarction, transient cerebral ischemia, and the mortality rate of these diseases is very high.

Through the above articles, I believe everyone has an understanding of the dangers of high blood pressure. It can be seen that hypertension not only has a relatively high incidence in life, but also is very harmful, so it is necessary to know more about hypertension, and take drugs under the guidance of doctors in time once any abnormalities occur, only in this way can complications and mortality be reduced.

High blood pressure damages the fundus, mainly when it affects the heart, brain, kidney and other organs severely, it will lead to bleeding spots in the fundus, resulting in eye damage and blindness.

Hypertension has an impact on the eyes, long-term hypertension will cause lesions of small arteries throughout the body, manifested in the thickening of the arteriole wall, narrowing of the lumen, will lead to ischemia of important target organs and tissues, and its impact on the fundus is generally divided into 4 levels: Level 1 will be manifested in retinal artery spasm and thinning. Grade 2 will manifest as retinal artery stenosis and arterial crossover compression.

Grade 3 manifests as hemorrhage or flocculent exudation from the fundus.

The harm of high blood pressure to the eyes is mainly due to the lesions of the fundus arteries, and the first clinical hypertension is not yet clear. It is generally believed that there is a certain correlation with long-term mental stress, irregular work and rest, excessive obesity and genetics, and the overactivation of the body's sympathetic endocrine system and renin-angiotensin-aldosterone system is an important mechanism leading to hypertension.

fundus ischemia occurs, and in hypertensive patients, the arteries become thinner and blood flow is relatively slow; The arterial endothelium is damaged, the inner wall of the blood vessel is rough and narrow, and it is easy to form blood clots

Hypertension has a great effect on the fundus, hypertension will cause changes in the heart, brain and kidney, and hypertension will cause fundus artery spasm and narrowing and even oozing hemorrhage.

How much damage does high blood pressure do to the fundus? High blood pressure is very damaging to the fundus, and severe fundus congestion can easily cause rupture.

How much damage does high blood pressure do to the fundus? High blood pressure is very damaging to the fundus. In severe cases, it is easy to cause fundus bleeding.

Long-term high blood pressure and rupture of blood vessels in the fundus can cause fundus bleeding and affect vision.

Patients with high blood pressure generally have venous vascular blockage, because the body's blood pressure and blood sugar will increase and the blood vessels will be blocked, resulting in venous blood vessel blockage. Long-term smoking can lead to an increase in the viscosity of blood in the veins, and the blood vessels are easily blocked. Irregular life and less exercise can lead to a decrease in the elasticity of blood vessels, a slowdown in the flow of blood, and blockages in blood vessels.

Among them, the retinal ** vein is blocked, which will cause arteriosclerosis of the fundus.

Fundus disease is a disease of the fundus, including the retina, optic disc and choroid. Fundus arteriosclerosis is a cumulative disease. The elderly are more likely to develop than the middle-aged and young people, and some of them are arteriosclerosis at the base of the eye based on the disease.

When the blood vessels at the bottom of the eye are blocked, the blood supply to the eye is insufficient, and the nutrients in the whole body cannot be delivered to the eye, which will lead to eye blindness in the long run. If detected in time, it is possible to rescue the newly blocked blood vessel and restore vision after the eventual recovery.

The compression of blood vessels caused by high blood pressure is a chronic accumulation process, so most of the ** effects will not be particularly obvious, and it is generally used to take drugs and other **. As long as the patient pays attention to rest, stays away from high-calorie and high-fat foods, eats more vegetables and fruits, prohibits smoking and drinking, and controls blood pressure.

Hypertension itself is not terrible, the biggest harm is the occurrence of hypertension complications, which can affect the heart, kidneys, brain, eyes and peripheral arteries and blood vessels, and the corresponding diseases appear, such as coronary heart disease, heart failure, kidney failure, cerebral hemorrhage, cerebral infarction, blindness, avascular necrosis of the arteries of the lower limbs, etc. Patients with high blood pressure over 90 140 mmHg are generally recommended to take antihypertensive drugs, which can play a role in dilating blood vessels. Long-term use of antihypertensive drugs dilates blood vessels and allows blood to pass smoothly, but makes blood vessels slowly become thin and brittle, which greatly increases the probability of cerebral hemorrhage with the prolongation of time.

Studies have shown that 70% of heart failure is caused by high blood pressure, and once heart failure develops, the five-year mortality rate is the same as that of lung cancer! High blood pressure leads to atrial fibrillation, which in turn leads to cerebral infarction. Clinically, 20% of cerebral infarctions are caused by atrial fibrillation.

Long-term studies have found that the incidence of end-stage renal disease increases significantly as blood pressure increases. In patients with severe hypertension, the incidence of end-stage renal disease is 11 times higher than in normotensive patients, and the risk increases to a factor even when blood pressure is at a high normal value.

Today, let's talk about the dangers of high blood pressure?

First of all, we need to know what hypertension is, high blood pressure has a standard in value, that is, 140 90mmHg, for ordinary people, if you want to know if you have high blood pressure, you can use an upper arm electronic blood pressure monitor, within an hour of getting up in the morning or before going to bed at night to measure. <>

When our blood pressure rises, the flow rate of blood vessels in our body will increase, which is equivalent to the pressure of the water pipe will become higher, so the water flow in the water pipe will be faster, which will bring a lot of harm.

When the blood vessel wall of our body is washed out and damaged, this will affect the permeability of the blood vessels, and the contents of the blood vessels will easily penetrate into the blood vessel walls.

For example, this will lead to the deposition of blood lipids under the blood vessels, which will form plaques, which will cause the originally elastic blood vessels to gradually lose their elasticity after the plaque gradually accumulates, and finally atherosclerosis.

The consequence of plaque is that the blood vessels are gradually narrowed and blocked, which will cause different degrees of symptoms, and at this time, it is necessary to place a stent in internal medicine for thrombectomy or surgical intimal decortication or big joe to carry out**. <>

If the pressure is too high, then the pipe will be broken, if it is broken in half, then a dissection will be formed, such as intramural hematoma, aneurysm, aortic dissection, and if it is all broken, then it is bleeding, such as cerebral hemorrhage, which is a very fatal problem.

Because all the organs of our body need blood to function normally, then if the organs are affected by high blood pressure, these organs with large blood flow and rich blood supply are the first to bear the brunt, and the most serious is the kidneys, heart, and brain. <>

And if the pressure in the blood pressure becomes high, the heart needs to work harder to supply the blood to the whole body, so how does the heart work hard? Because cardiomyocytes are produced by contraction, when the blood pressure is higher, the longer the high blood pressure, the more these cardiomyocytes have to work hard, and if the blood pressure has been rising, then these cardiomyocytes will have been working hard, and in the end, because the cardiomyocytes are damaged, the heart will become hypertrophied, and in the end, it will become heart failure.
