What are the symptoms of glaucoma in children?

In life, glaucoma is a difficult eye disease and is very serious. However, with the progress of society, this disease is becoming more and more common among children. It is very painful and causes children's vision to deteriorate and become very blurred. It may even cause various complications, which seriously affect children's health and growth and development. Therefore, we must pay attention to it and discover it early. So what are the symptoms of glaucoma in children?

1. Headache and eye swelling: Due to the sharp increase in intraocular pressure, the endings of the trigeminal nerve are stimulated, which reflexively causes pain in the trigeminal nerve distribution area. Patients often feel migraine and eye swelling.

2. Narrowing of the visual field and decreased vision: Due to high intraocular pressure, the optic nerve is damaged. In the early stage, decreased vision and foggy vision often appear at night and disappear in the next morning.

3. Iris vision: Due to increased intraocular pressure and impaired circulation of intraocular fluids, corneal edema and refraction changes occur. At this time, when looking at sunlight, especially light, a colorful ring with an orange-red outer circle, a purple-blue inner circle, and a green center will appear. When the intraocular pressure returns to normal, the colored ring disappears. This phenomenon is called rainbow vision in medicine.

4. Nausea and vomiting: Increased intraocular pressure can also reflexively cause excitement of the vagus nerve and vomiting nerve center, resulting in severe nausea and vomiting.

5. Symptoms of glaucoma in children include increased intraocular pressure: measured by a Scheherazade tonometer, the normal intraocular pressure range is 10-21 mmHg, and the eyeball is elastic when touched with a finger. When the intraocular pressure rises to 25-40 mmHg, the eyeball feels hard like an inflated ball when touched with a finger. When it rises to 40-70 mmHg, the eyeball will feel as hard as stone when pressed with your fingers.

In our minds, children are very fragile, so we should pay attention to glaucoma in children, because severe glaucoma can cause blindness. First of all, parents and friends should let children watch less electronic screens, because electronic screens put too much pressure on the eyes. Glaucoma means excessive pressure on the eyes, which is very harmful to the eyes.
