Visual vision, decreased vision, beware of invisible vision thieves -open -angle glaucoma

When it comes to the symptoms of glaucoma, some patients may have significant clinical manifestations such as redness, eye pain, headache, and vomiting; some patients may not feel any discomfort, and when they have symptoms such as visual vagueness and other symptoms, they will seek medical treatment. However, it was told that it was the middle and late stages of glaucoma.

What is the reason for this?

Zheng Hua, Dean of Huaihua El Eye Hospital, said that this has something to do with the type of glaucoma.

Glaucoma can be divided into open glaucoma and closure glaucoma.

Generally speaking, patients with a closure glaucoma have obvious symptoms of discomfort, while the open -angle glaucoma may come silently.

How to distinguish between opening and closing?

Literally, the two types of glaucoma are only the difference between the word, and the "angle" pointed to the "opening" and "closed" is a structure inside the eyes. We call it "room angle".

The angle between the cornea and the iris is called the corner of the room. The corner of the room has very important functions. If the corner of the house is closed, the water flowing out will be blocked, and the pressure in the eyes will rise due to the convergence of the water accumulation, which will lead to the occurrence of glaucoma.

In layman's terms, our eyes are constantly secreting "housing water", and "housing water" needs to be discharged through a structure called "housing horn".

Therefore, the "room horns" are like the drainage of the eyes. The corner -closing glaucoma is because the drainage port is too narrow and the acute closure is closed; the open -angle glaucoma is a problem with the filter of this drainage. The filtering is not good.

"Thief of vision"

Most of the open -angle glaucoma has no significant clinical manifestations such as redness, eye pain, and headache. Instead, it is hidden and the progress is relatively slow.

Therefore, it is not easy to be found to slowly damage the optic nerve unknowingly. When the patient finds it, most of them are in the late stage of glaucoma, and the optic nerve has been severely damaged and cannot be recovered.

This ophthalmological disease is often bilateral. When the field of vision was reduced to the tubular period, symptoms such as inconvenience and night blindness occurred, resulting in completely blindness.

Because of this, open -angle glaucoma is often called "thief of vision".

Who is prone to open corner glaucoma?

Age: Corner glaucoma is common in elderly people over 50 years old, but it is also seen in the age of 30-40 or even teenagers.

Genetic: Corner glaucoma has proven to be a family history and hereditary disease. 25%of patients have family history. The prevalence of direct -family relatives in patients with glaucoma is at least 15 times higher than that of ordinary people.

Diseases: High myopia, retinal vascular diseases, and some basic diseases, such as diabetes and hypertension patients, need to pay attention to the possibility of post -posting corner glaucoma.

Dean Zheng Hua warmly reminded: Corner glaucoma can reduce intraocular pressure through drugs or surgery, and prevent further damage to the optic nerve, so it is controllable.

However, optic nerve injury and lack of vision are irreversible, so it is essential to achieve early, early diagnosis, and early treatment.

Groups with a family history of glaucoma should regularly go to professional ophthalmology medical institutions for intraocular pressure, field of vision, and bottom of the eye to open up early discovery and early treatment of corner glaucoma.
