Do you know which are the top three treatments for blinding eye diseases in the world?According to the World Health Organization (WHO), the three major blind eye diseases in the world include: cataract, glaucoma and macular degeneration. These three eye diseases have a serious impact on people all over the world.
According to the World Health Organization's first World Report on Vision, more than 1 billion people worldwide are visually impaired because they do not have access to the necessary medical or nursing services to address problems such as nearsightedness, farsightedness, glaucoma and cataracts. Let's talk about glaucoma, one of the three major eye diseases.
What is glaucoma?
Glaucoma is a group of diseases characterized by atrophy and sunken papillae, visual field defects and decreased vision, pathological intraocular hypertension and optic nerve insufficiency are the primary risk factors for its pathogenesis, and the tolerance of optic nerve to pressure damage is also related to the occurrence and development of glaucoma.
glaucoma).
What are the symptoms of the anterior stage of glaucoma?
Elevated anterior chamber pressure (mild): Patients may have no obvious symptoms, but they may have symptoms such as blurred vision and dry eyes.
Elevated posterior chamber pressure (moderate): Patients may experience symptoms such as headache, nausea, vomiting, and reduced visual field.
Persistently elevated intraocular pressure (severe): At this time, the patient may develop severe visual impairment and even blindness.
Advanced stage (very severe): At this time, the patient has lost most of their vision, often accompanied by pain and other discomfort.
What are the factors that contribute to glaucoma?
1. Increased intraocular pressure.
Pathologic intraocular hypertension is a major risk factor for glaucoma. Elevated intraocular pressure leads to optic nerve damage through two mechanisms: mechanical compression and causing optic nerve ischemia. The longer the increase in intraocular pressure persists, the more severe the visual impairment. The increase in intraocular pressure in glaucoma is caused by a disruption of the homeostasis of the aqueous humor circulation. A small number of aqueous humor secretions are due to excessive aqueous humor secretion, but most of them are still obstructed by aqueous humor outflow, such as narrowing or even closure of the anterior chamber angle, trabecular sclerosis, etc.
Second, the disease ** element.
High blood pressure: High blood pressure will cause arteriosclerosis and hardening of blood vessels, and when it develops to a certain extent, it will cause insufficient blood supply to the retinal optic nerve, resulting in ischemia of the optic nerve and causing glaucoma.
In addition to the above reasons, the occurrence of glaucoma is also related to myopia, lifestyle Xi, age, eye diseases such as cataract or diabetic retinopathy, etc. Therefore, it is particularly important to prevent glaucoma, so how can we prevent glaucoma in life?
1.Maintain a healthy lifestyle and avoid excessive fatigue and stress;
2.Regular eye examinations are carried out, as glaucoma has no symptoms in the early stages, so it is important to detect and ** any potential eye problems in time
3.Control chronic conditions such as high blood pressure and high blood sugar, which increase the risk of glaucoma;
4.Pay attention to a balanced diet, eat more vegetables and fruits, and reduce the intake of high-fat foods
5.Quit smoking and limit alcohol and try to avoid smoking and drinking: For people with glaucoma, it is important not to smoke, but to drink in small amounts.
Because the nicotine contained in cigarettes can cause optic nerve vasospasm and optic nerve ischemia, the optic nerve damage in glaucoma patients will be aggravated faster. However, excessive consumption of high-concentration alcohol may damage the optic nerve, especially in patients with glaucoma, which can seriously affect the prognosis.
For now, blindness caused by glaucoma cannot be reversed with the current level of medical care, so it is particularly important to prevent glaucoma. I hope you can take good care of your eyes.
