Fundus vascular lesions lead to blindness, what causes fundus vascular lesions?

Fundus lesions can cause a variety of causes, such as genetic inheritance, trauma, inflammation, and vascular lesions, which can cause fundus lesions, such as widespread night blindness, which is a genetically inherited fundus lesion, which can be seen in the retina with excessive osteoid cell accumulation, visual field defects, vascular aging, and subsequent optic disc aging. Vascular lesions such as retinal vein blockage, postretinal bleeding occurs after the venous vessel is blocked, and revascularization occurs after hemorrhage, resulting in a variety of complications. Inflammation like uveitis or retinitis can also cause retinal lesions.

The most critical change of retinopathy to the middle and later stages of this retinopathy is to harm the eyesight, damage to the change of color and detailed vision of the eye, resulting in visual field defects, so the causes of fundus lesions are varied.

Fundus lesions mostly refer to retinopathy, and there are many causes. Retinopathy is further divided into vascular diseases, yellow spot diseases, and ocular nerve and optic pathway diseases. For example, the blockage of the aora and venous vessels in the retina is mostly considered to be due to the patient's high blood pressure, high blood lipids or blood viscosity.

When there is inflammation, the pus plug is blocked, causing the blood vessel to be blocked. When blood vessels are inflamed, it will directly affect the blood supply to the eyes and produce retinal vasculitis. There are some medical conditions, such as high blood pressure, which can cause retinopathy of the eye in diabetics.

Macular degeneration is related to age, and yellow spots cause degenerative changes as the age increases. In addition, trauma, lack of nutrition, fatigue can cause macular dehiscence, lack of nutrients in the melanin epithelial tissue and its cystic deformation, etc. Congenital factors, such as retinal melanin metastasis and blastoma, are also caused.

Neurological, optic pathway pathways are associated with critical and crushing, blood supply, and inflammation.

Fundus lesions have a variety of causes, such as genetic inheritance, trauma, inflammation, and vascular lesions, all of which can cause fundus lesions, such as the commonly used night blindness is hereditary fundus lesions, and retinal osteoid cell deposition, visual field defects, vascular aging, optic nerve atrophy, etc. Vascular lesions such as retinal vein vascular blockage, retinal bleeding after venous vessel blockage, regeneration of blood vessels after hemorrhage, inflammation like uveitis and retinitis, this inflammation can also cause retinopathy. The biggest changes in this retinopathy are that it harms the eye's vision and causes a variety of fundus lesions.

The eye usually refers to the structure inside the eye, including the vitreous, retina, ocular nerves, etc., and eye diseases refer to the lesions of the above structures caused by various factors. A variety of diseases can cause fundus lesions, such as diabetic patients, high blood pressure, frailty in the elderly, high myopia, polyphthalmia, eye trauma, etc., and the vision of the eyes is significantly reduced. Therefore, when the eyesight is reduced, fundus examination should be carried out as soon as possible to establish the type and level of lesions, and medical treatment should be carried out according to the physical condition to prevent further aggravation of lesions.

It is caused by genetics, or it may be due to the blockage of the blood vessels in the retina, which will eventually lead to fundus vascular lesions.

The cause of fundus vascular disease is inflammatory disease, high blood pressure, diabetes, etc., or mechanical blockage.

It is likely to be caused by the sclerosis of the retinal blood vessels in the fundus, which eventually leads to undernutrition of the fundus tissues and the appearance of vascular lesions in the fundus.

It can be caused by high blood pressure, diabetes, cardiovascular disease, inflammation, high blood sugar.

The symptom is vision loss, which may cause some neurological diseases, or it can also cause some retinal diseases, the color of our pupils will also be changed, and we can't see clearly, we will have this feeling of nausea, vomiting, and increased intraocular pressure, which is particularly uncomfortable.

First of all, the vision is blurred, the vision is reduced, and then there will be double vision when looking at things, and in severe cases, it is likely to cause the cornea to fall off, and often feel that there is a black shadow floating in front of your eyes, which may affect your hearing, and there may be retinopathy.

Vision decreases, the discharge of the eyes increases, the eyes are particularly uncomfortable, there is some painful feeling, there is some itching feeling.

1. Mechanical obstruction, such as thrombosis, etc.;

2. Inflammatory diseases or immune complexes that invade the blood vessel wall, such as periretinal venous inflammation, optic disc vasculitis, etc.;

3. Systemic vascular diseases and blood diseases, such as hypertension, diabetes and other retinopathies;

4. Retinal vascular abnormalities, a variety of different ** lead to the same pathological damage, such as retinal hemorrhage, exudation, microhemangioma, neovascularization, etc.

Retinal ** artery occlusion; retinal ** vein occlusion; periretinal venous inflammation; periretinal arteritis; hypertensive retinopathy; nephrotic retinopathy; diabetic retinopathy; Curts disease (coats); retinal hemangioma; Choriochoroidal hemangioma.

1. Retinal detachment from fundus lesions.

Retinal detachment is the separation of the neuroepithelial layer of the retina from the pigmented epithelial layer. There is a latent gap between the two layers, and the fluid that remains in the space after separation is called subretinal fluid. According to **, it can be divided into rhegmatogenous, traction and exudative retinal detachment.

Exudative retinal detachment can occur in severe inflammation of the eye, ocular or systemic circulatory disorders, choroidal or orbital tumors, etc., the retina is mostly without tears, and after control, the detached retina can be reduced. The disease is more common in middle-aged or elderly people, most of whom are nearsighted, and both eyes can develop sequentially.

2. Retinal degeneration fundus lesions.

It is a chronic, progressive degenerative disease of the retinal pigment epithelium and photoreceptors with a pronounced genetic predisposition. It can be inherited in an autosomal dominant or recessive manner, and there are also sporadic cases. It begins in childhood and worsens during adolescence, affecting both eyes.

At present, it is believed that retinitis pigmentosa is caused by the defect of the highly developed phagocytic enzyme system in the pigment epithelium, which leads to defects in the phagocytosis of the extracellular segments of photoreceptors, especially the outer rod segments, which affects the metabolism of the outer segments, and the detached disc membrane accumulates, which may become autoantigens and autoimmune reactions. This defect in the pigmented epithelium is associated with genetics. This is also one of the symptoms of fundus vascular lesions.

3. Optic neuritis fundus lesions.

Local inflammation, such as uveitis, retinitis, and sympathetic ophthalmia, can spread to the optic nerve; Orbital infection, paranasal sinusitis, dental caries, tonsillitis and other lesions can directly involve or cause optic nerve inflammation through blood circulation or induce allergies to the optic nerve and intraocular tissues, resulting in optic nerve inflammation.

As the name suggests, fundus vascular lesions are lesions on the fundus, which is not the name of an eye disease, but a combination of many eye diseases. Fundus lesions include inflammation of the retinal flexion, choroid, optic nerve and vitreous humor, tumors, and lesions of various blood vessels, and there are many causes of fundus lesions, such as diabetes, nephritis, anemia, influenza, tuberculosis, etc.
