How is the eye formed, at what age, and what are the effects on the eyes?

Glaucoma is caused by an abnormal increase in intraocular pressure, which is usually caused by an abnormality in the eye's pumping system, where the drainage ducts are blocked or covered, and the ciliary body constantly produces aqueous humor. In other words, the water pipes are still open, but the drain of the sink is clogged. Excess aqueous humor that accumulates in the eye compresses the weakest point of the eye, the optic nerve at the back of the eye.

If the intraocular pressure is too high for a long time, it will damage part of the optic nerve, and this damage will manifest as partial damage to the visual field in the early stage, and eventually loss of vision. Early vision changes are very slight and do not affect the ** part. The peripheral visual field is the first part to be affected, and it is not easy for the patient to notice.

Age of onset of glaucoma 1. Congenital glaucoma: According to the age of onset, it can be infantile glaucoma and juvenile glaucoma. Glaucoma under the age of 30 falls into this category.

Congenital glaucoma is caused by the anterior chamber angle during embryonic development 1 Infantile glaucoma: Children aged 0-3 years with glaucoma are generally classified as such. 2 Juvenile glaucoma:

The age of onset is between 3 and 30 years. 2. Primary glaucoma: according to the morphology of the anterior horn of the anterior chamber and the severity of the disease, it is divided into acute and chronic angle-closure glaucoma, open-angle glaucoma, etc

1 Acute angle-closure glaucoma: The occurrence of acute angle-closure glaucoma is caused by the sudden narrowing or closure of the angle in the eye, and the aqueous humor cannot be discharged in time, resulting in the filling of aqueous humor and a sharp increase in intraocular pressure. It is more common in middle-aged and elderly people, and 90% of them are over 40 years old.

2 Chronic angle-closure glaucoma: This type accounts for more than 50% of patients with primary glaucoma, and the age of onset is over 30 years old 3 Primary open-angle glaucoma: It mostly occurs in people over 40 years old.

25% of patients have a family history. Developmental abnormalities that impede the discharge of aqueous humor and increase intraocular pressure. It is shown in 25-80% of patients within six months, and 90% of children are diagnosed by the age of one year.

Symptoms develop in 10% of patients between the ages of 1 and 6 years. Glaucoma usually occurs in both eyes, but it manifests first in one eye. Some patients do not have any symptoms of discomfort or pain, while others have severe symptoms, such as:

Blurred vision, headache or eye pain, nausea or vomiting, rainbow halo around lights and sudden loss of vision.

There will be blurred vision, and others will look at you like the eyes of foreigners

In general, high intraocular pressure and staring at a computer or mobile phone for a long time in the dark can easily cause glaucoma.
