Why does diabetes cause blindness, diabetes blindness, and in what period is it generally?

How does diabetes blind a person? There are many complications of diabetes, diabetic eye disease is one of them, it can be a lot of lovely life blindness, among them, the most prominent diabetic eye disease is neovascular glaucoma, sudden blindness cataract, retinal detachment, which is the most serious complication, so some people call it the "three killers" of diabetes blindness.

1. Neovascular glaucoma.

Glaucoma accounts for 20% of all blind people. There are many types of glaucoma, among which the most difficult to treat is neovascular glaucoma, which is ferocious, and often painful when it is painful, and the ** rate is very low. Diabetic glaucoma is mostly neovascular glaucoma, which often occurs in the middle and late stages of diabetic retinopathy, and ischemic changes in the retina lead to iris neovascularization, which then causes neovascular glaucoma.

Due to the rapid development of neovascular glaucoma, vision declines sharply, which can be accompanied by symptoms such as eye pain, migraine, nausea, vomiting, etc., and in severe cases, a large amount of intraocular bleeding can occur, and it is difficult for drugs to work. Surgery** often fails due to re-adhesion and closure of the new filter port after surgery.

2. Retinal detachment.

The endpoint of diabetic retinopathy is retinal detachment. Diabetic retinopathy can be divided into six stages, with the continuous change of the course and condition of diabetes, diabetic retinopathy is also gradually aggravated, and the increase in blood sugar is a catalyst for the development of diabetic retinopathy.

When localized retinal detachment occurs, a blind spot – a visual field defect – is created within the corresponding range. Once the retina is completely detached, it will lead to total blindness.

Retinal detachment due to diabetic retinopathy requires surgery**. Early surgery** is a prerequisite for restoring visual function, and early small-scale retinal detachment reduction surgery can save part of the visual function, while large-scale retinal detachment surgery has a poor prognosis.

3. Cataract of sudden blindness.

Cataract caused by diabetes is called diabetic cataract or concurrent cataract, which ranks second among eye diseases complicated by diabetes and is one of the important causes of blindness caused by diabetes. It occurs in the presence of high blood glucose, altered osmotic pressure of the aqueous humor, and toxic products produced by metabolic disorders. Cataracts caused by hyperglycemia are also known as true diabetic cataracts. In the later stage of diabetes, self-cataract caused by lens metabolism disorder caused by pigmentitis and severe diabetic retinopathy is also known as concurrent cataract.

True diabetic cataract occurs mainly in young patients with severe diabetes, but it can also occur in young children, and it is less common in middle-aged and older people. Both eyes often develop at the same time, and the rate of progression is rapid, often reaching maturity in a few days.

Diabetic cataract can partially regain clarity if blood sugar is controlled in time at the beginning of the disease. Once the lens is completely clouded, surgery is the only way to restore vision. If it is not timely, it can quickly cause blindness, so it is called sudden blind cataract.

The disease is preventable, and the "dark" can be avoided by controlling blood sugar, having regular check-ups, and treating eye complications early.

This is just one of the complications of diabetes, not only can it lead to blindness, there are hundreds of complications of diabetes, you have to accept it quickly**, otherwise it may lead to other complications.

Diabetes, blurred eyes, which means diabetic microangiopathy, diabetic eye disease, including diabetic retinopathy and cataracts. Therefore, this eye disease is not a daily overuse of the eyes or dark vision. When the blood sugar of a diabetic patient cannot be effectively controlled, consuming some nutrients or foods that themselves help improve vision can easily lead to eye complications.

Especially for patients with a long course of disease, the chance of suffering from eye diseases is high, which requires us to control blood sugar and blood pressure, always pay attention to changes in the eyes, detect and deal with time, and adjust life and diet.

Diabetic retinopathy is one of the most common microvascular complications of diabetes. Increased risk of blindness is mainly related to the course of diabetes, long-term hyperglycemia, hypertension, hyperlipidemia, etc. Therefore, it is very important to check for diabetic retinopathy as soon as possible by controlling these indicators.

Diabetic eye disease is one of the complications of diabetes that both doctors and patients take very seriously as it can eventually lead to blindness. Long-term abnormal blood sugar will lead to the destruction of microfilaments and blood vessels, the lens will be in a state of high sugar for a long time, the corneal perception ability will be weakened, the repair ability will be poor, and the formation of cataract will be accelerated.

Diabetes can cause a variety of complications, including many eye diseases such as diabetic retinopathy, diabetic cataracts, diabetic glaucoma, etc., and in the early stages of these complications, diabetic eye blurring may occur. It is recommended that you go to the hospital for an eye exam, which is a very common problem. There are many cases of blurred vision caused by diabetes.

In the initial stages, this condition is usually due to changes in glucose in the blood, such as changes in vitreous osmotic pressure and changes in vision, and in the final stages, it can be retinopathy.

Generally, it is in the middle and late stages, because the physical condition at this time is getting worse and worse, and then the blood sugar is getting higher and higher, so it is easy to affect the vision.

Diabetic blindness generally refers to the occurrence of diabetic complications, the cause of diabetic blindness is due to retinopathy, which can delay diabetic blindness by controlling blood sugar.

Generally, it will occur in the middle and late stages of diabetes, which is already a more serious period, so it will lead to blindness.

It is in the middle stage of diabetes that blindness occurs, which is actually a complication caused by diabetes.

Diabetic blindness generally occurs during the period of chronic complications, mainly due to microangiopathy.

Diabetic retinopathy is caused by the long-term invasion of high blood sugar and causes retinal capillary circulation disorders in the eye: blood flow is sluggish, tissue hypoxia, capillary wall degeneration becomes brittle, and microhemangiomas, punctate or patchy hemorrhages, and cotton wool exudation appear on the posterior polar retina of the fundus, resulting in vision loss. If this is not done in time**, the lesion will develop further.

The lack of oxygen causes new blood vessels in the retina of the eye, which can cause vitreous hemorrhage, reproductive retinopathy, and blindness.

The excellent antioxidant properties of lutein can significantly improve the resistance of blood vessels, restore the balance of osmotic pressure lost inside and outside blood vessels, reduce vascular permeability, inhibit the leakage of substances in blood vessels, ensure the integrity of blood vessels in the eyes, and allow the eyes to get sufficient blood**.

Judging from the current data, neither Western medicine nor Chinese medicine can completely ** type 2 diabetes.

Type 2 diabetes is characterized by insulin resistance, where insulin is present in the body, but it does not work.

Hello and thank you for your question. Whether or not diabetic blindness can recover depends on the severity of the disease, as well as the stage and duration of the diabetic retina. In general, diabetic retina is divided into six stages.

Stage 4 to 6 can lead to blindness. Early** can save your vision. Don't wait until the last installment, the chances of being cured are greatly reduced.

Diabetic retinopathy and diabetic macular edema are the most common fundus complications of type 2 diabetes, which seriously affect the vision of patients and are the first blinding eye diseases in the working population in developed countries and regions.

Characteristics: There are no self-conscious symptoms in the early stage, and there are varying degrees of vision loss after the lesion develops to the macula. In our country, the vast majority of patients not only do not receive regular screening, but often only seek medical attention when there are obvious symptoms of visual impairment.

Proliferative diabetic retinopathy, a patient with diabetes for 10 years, no vision loss, only a small number of hemorrhagic foci on color photography, and a large number of retinal neovascularization on fundus angiography.

In the same proliferative stage of diabetic retinopathy, the patient has no vision loss, and a large number of retinal neovascularization can be seen on fundus angiography.

In the same proliferative stage of diabetic retinopathy, the patient has no vision loss, and a large number of retinal neovascularization can be seen on fundus angiography.

Diabetes mellitus is a metabolic disorder, also known as "vascular disease", long-term blood sugar increases, large blood vessels, microvasculature will be damaged, endangering the whole body organs.

The retina is full of dense blood vessels, once the blood vessels are out of order, the energy can't pass, the cells are inactivated, and eventually, the eyes are blurry and unable to see clearly.

When diabetic patients have fundus hemorrhage, optic nerve atrophy, vision loss, blurred vision and other phenomena, they should be checked in time for diabetic eye disease. So, can long-term diabetic eye disease cause blindness? If diabetics do not control their blood sugar well for a long time, it can lead to blindness.

As a result, diabetes can cause blindness. Diabetic eye lesions can lead to blindness. Long-term hyperglycemia can lead to permanent vision loss and even blindness.

Currently, retinopathy of the eye caused by diabetes accounts for more than 60%. People should pay attention to the examination of eye diseases, have regular examinations once every six months, diagnose early** early and pay attention to diet, so as to effectively prevent eye diseases.

Diabetic patients with diabetes for more than five years have a 35% chance of developing eye disease. When diabetic patients have fundus hemorrhage, optic nerve atrophy, vision loss, blurred vision and other phenomena, they should be checked in time for diabetic eye disease.

This condition, called diabetic optic neuritis, is caused by damage to the nerves in the eye caused by high blood sugar, which requires strict blood sugar control**.

One of the complications is that diabetic patients are particularly symptomatic, as long as the blood sugar is kept normal for a long time.

It can cause blindness, so be careful!

Possibly, as long as the blood sugar is stable for a long time, it can effectively delay the appearance of this condition!

There is such a possibility. Diabetic eye disease is serious.

Hello. In the early stage, retinopathy can appear as background changes such as hemorrhage, edema, microhemangioma, and exudation, and in the late stage, neovascular proliferative lesions appear, which are often irreversible and are an important cause of blindness in diabetic patients. Although good glycemic control can delay and reduce the progression of diabetic retinopathy, it cannot prevent the progression of diabetic retinopathy.
