What is Glaucoma

Glaucoma is an irreversible blinding eye disease caused by intraocular pressure (IOP) exceeding the tolerance of the optic nerve, which causes visual impairment, optic nerve atrophy and visual field loss.

Glaucoma is the world's leading irreversible blinding eye disease. Pathologically increased intraocular pressure is its main risk factor. It can occur at any age and is more common in middle-aged and elderly people.

Types of Glaucoma

According to the shape of the anterior chamber angle, etiology and age of onset, glaucoma can be divided into three categories: primary, secondary and congenital glaucoma. In China, primary glaucoma is the main type.

Acute angle-closure glaucoma: This type of glaucoma often develops acutely, with symptoms including eye swelling and pain, decreased vision, as well as headaches, nausea, vomiting, etc.

Chronic angle-closure glaucoma: This type of glaucoma does not have obvious symptoms such as eye swelling and headache, but there may be soreness and swelling at the root of the nose, large fluctuations in intraocular pressure, and iridescence (that is, when looking at a light, a rainbow-like halo appears around the light).

Primary open-angle glaucoma: This type of glaucoma has a hidden onset and may not have any obvious symptoms in the early stages. It is only discovered when it develops to the middle and late stages, when the optic nerve is severely damaged, vision is reduced, and visual field damage is obvious. Therefore, this type of glaucoma requires more vigilance!

What are the risk factors for glaucoma?

0 1 Glaucoma has certain genetic factors . People with a family history of glaucoma have an increased incidence rate. If a first-degree relative such as a parent, brother, or sister suffers from glaucoma, the incidence rate will increase by 5 to 10 times.

0 2 Patients with high myopia or high hyperopia ;

0 3 If you have a history of retinal hemorrhage , the risk of developing glaucoma will increase. It is recommended to have regular eye examinations;

0 4 Suffering from diabetes, cardiovascular system diseases, snoring and other diseases;

0 5 Long-term use of glucocorticoid drugs;

06 Personality and psychological factors such as high mental stress , frequent and drastic changes in negative emotions.

Symptoms of Glaucoma

At present, the public's awareness of glaucoma is low, and the early symptoms of the disease are easily ignored. Many patients do not seek medical treatment until their vision is significantly reduced in the middle or late stages. Glaucoma patients may experience the following symptoms:

0 1 Iridescence phenomenon occurs

When you look at lights at night, a rainbow-like halo appears around the lights . This rainbow halo is medically known as the "iris vision" phenomenon. It is accompanied by a decrease in vision and is one of the typical symptoms of glaucoma. It is recommended to seek medical attention as soon as possible.

02Vision declines in a short period of time

This situation is more common at night. Some people think it is just visual fatigue when it happens. After a night's sleep, they find that their vision has recovered and they think everything is fine. In fact, this is a manifestation of glaucoma attack . If treatment is delayed, an acute attack will occur and the best time for treatment will be missed.

03Headache, nausea and vomiting, eye pain

It is the most typical symptom of an acute attack of glaucoma. It cannot be relieved by taking painkillers. Some people mistakenly think that it is caused by headache and go to the neurology department for treatment. It is eventually discovered that the headache is caused by glaucoma . Acute increase in intraocular pressure can cause irreversible damage to the optic nerve in a short period of time.

04No symptoms

Chronic angle-closure glaucoma and primary open-angle glaucoma may not have any symptoms . Some people only have mild eye swelling, soreness and swelling at the root of the nose, etc. , especially normal-tension glaucoma, which has almost no symptoms. Therefore, not all types of glaucoma have obvious symptoms. People with high-risk factors should have regular eye examinations . If they have risk factors such as high myopia, snoring, and low blood pressure, they should go to the ophthalmology department to check for glaucoma every year to avoid delaying the disease.

The glaucoma specialist at Wuhan University Aier Eye Hospital reminds that because some glaucoma (open-angle and chronic angle-closure) symptoms are atypical, most patients do not pay enough attention to them. When they are diagnosed, they are often in the middle or late stages. At this time, the optic nerve has often atrophied and visual field defects have occurred, missing the best time for treatment. Therefore, it is recommended that everyone, especially the middle-aged and elderly, should have an eye health check-up every year to screen in time and detect and treat early.
