What causes vision loss?

The causes of vision loss are:

1. Inflammation is the most common cause of blurred vision

Infectious: keratitis, corneal ulcer, iridocyclitis, choroiditis, endophthalmitis, panophthalmitis, orbital cellulitis caused by bacteria, viruses, chlamydia, fungi, parasites, etc.

Non-infectious: vesicular interstitial keratitis, uveitis (including iris, choroiditis), sympathetic ophthalmia, Harada disease, etc.

2. Refractive error: myopia, farsightedness, astigmatism, presbyopia.

3. Strabismus and amblyopia.

4. Ocular trauma: perforation injury, blunt trauma, ** injury, chemical burn, radiation injury, etc.

5. Glaucoma.

6. Sequelae caused by various eye diseases: corneal scarring, pupillary membrane closure, pupillary atresia, vitreous opacity.

7. Systemic circulatory and metabolic disorders and hereditary diseases

Hypertensive retinopathy, diabetic retinopathy, nephritic retinopathy, gestational hypertension syndrome retinopathy, hematopathic retinopathy, retinitis pigmentosa, macular degeneration, ischemic optic neuropathy, Leber disease and other fundus lesions, cataracts.

8. Retinal vascular disease and retinal detachment: retinal artery occlusion, retinal vein occlusion, serous chorioretinopathy of the heart, retinal vasculitis, retinal detachment, etc.

9. Senile and degenerative lesions: senile cataract, corneal degeneration, senile macular degeneration.

10. Tumors: intraocular tumors, orbital tumors or eyelid tumors that invade the eyeball, etc.

11 Eye strain: unhygienic or eye malnutrition when using the eyes, etc.

12. Others: optic pathway lesions.

It is likely to be caused by glaucoma, which needs to be diagnosed in time, the disease will stay in the dark for too long and cause fundus headache, blurred vision, and foggy eyes, when hypertension develops to a certain extent, it can make the fundus retinal arteriosclerosis, edema, reduce blood flow, and reduce vision. Diabetes thickens the walls of arteries throughout the body, especially the arterioles on the retina, due to an increase in blood sugar. Severe lesions can occur, resulting in decreased vision and difficulty seeing distant or near objects.

There are many causes of vision loss. If you want to have vision loss, you should pay attention to the rational use of your eyes in your daily life, rest more and stay up late, play less with electronic products, mobile phones and computers, pay attention to eye hygiene, and eat more fruits and vegetables that are good for your eyes. Many eye diseases can cause vision loss, such as myopia, cataracts, glaucoma, fundus disease, etc.

Different diseases cause vision loss in different ways. Myopia is due to the elongation of the eye axis, which prevents light rays from being concentrated on the retina, which requires the wearing of concave lenses.

Cataract is the opaque lens in the eye, which blocks external light from entering the eye, naturally causing vision loss; When glaucoma occurs acutely, it will cause corneal edema, which is equivalent to clear glass becoming frosted glass, and vision will decrease, so it is necessary to reduce intraocular pressure in time and reduce damage to eye tissues; Eye diseases such as diabetes and high blood pressure are also major causes of vision loss. There are many causes of vision loss, and according to different symptoms, it is usually divided into: ** vision loss, which is mainly manifested in cataracts, refractive errors, and chronic retinal diseases.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

My behavior is not particularly good, and I am too close to books and computers when I use my eyes, I don't pay attention to taking care of my eyes, and I often squint to see things. Glaucoma, cataracts, and some retinal diseases can all cause vision loss, and can also lead to insomnia in your own vision, which will cause you to lose sight completely.

In the case of teenagers and children, it is mainly caused by excessive eye use; Glaucoma, cataracts, retinal detachment, conjunctivitis, keratitis, dry eye.

Mainly because you overuse your eyes or are constantly facing electronic devices. Or dry eye disease, pink eye, as well as palpitations, palpitations.

Inappropriate use of the eyes can lead to vision loss. Lesions of the cornea, uveal disease, vitreous, retinal disease. Glaucoma, cataracts.

Generally speaking, the first thing to look at is the quality of the naked eye, if it can be corrected with glasses, it is a refractive error. If there is a clouding of the lens of the eye, it is a cataract and severe cases require surgery**. In addition, it may be a problem with the retina of the fundus, degeneration of the retina, lesions, blood vessel lesions, etc., which can lead to vision loss.

Vision loss is the most common symptom of ophthalmology, and there are many causes of it, which can be divided into the following conditions according to different manifestations. Clause.

1. Transient loss or loss of vision, which returns to normal within 24 hours, is more common in fundus artery embolism, excessive fatigue, etc. Clause.

2. ** vision loss, usually seen in retinal artery or vein occlusion, ischemic optic neuropathy, vitreous hemorrhage, etc. Clause.

3. Progressive ** vision loss, usually seen in cataracts, refractive errors, chronic open-angle glaucoma and other diseases. Clause.

4. Sudden loss of vision, accompanied by eye pain, more common in acute angle-closure glaucoma, endophthalmitis, uveitis, etc. Therefore, it is recommended that once there is vision loss, it is necessary to go to the hospital for examination as soon as possible**, and **symptomatic**.

There are many causes of vision loss, such as refractive error caused by long-term excessive use of the eye, and other eye diseases such as glaucoma, cataract, and fundus lesions. In addition, eye inflammation and infection can also cause vision loss. It is recommended that you go to the ophthalmologist to find out** and then treat the symptoms**.

What are the common causes of vision loss? Most of them are related to 3 reasons.
