What's up with the eyes shining

Bright eyes can be said to be a compliment. But did you know that some diseases can also cause our eyes to glow? Generally speaking, bright eyes are likely a sign of glaucoma. Of course, we cannot conclude that it is glaucoma simply by the glowing eyes. Generally speaking, if you suffer from glaucoma, different types of patients will have different symptom reactions. Let’s learn about it today.

Primary glaucoma is divided into angle-closure glaucoma and open-angle glaucoma according to the state of the anterior chamber angle when intraocular pressure rises. Angle-closure glaucoma is further divided into acute angle-closure glaucoma and chronic angle-closure glaucoma according to the rapidity of onset.

1. Acute angle-closure glaucoma

Acute angle-closure glaucoma occurs when the intraocular angle suddenly narrows or closes, which prevents the aqueous humor from draining out in time, causing the aqueous humor to fill up and the intraocular pressure to rise sharply. It is more common in middle-aged and elderly people, with 90% of those over 40 years old. The incidence rate is higher in women, with a male to female ratio of 1:4. It is ferocious and has acute symptoms. Before the acute onset, there may be transient or repeated minor attacks, manifested as sudden blurred vision, rainbow vision, accompanied by forehead pain or soreness and swelling at the root of the nose. When the disease occurs, the anterior chamber is narrowed or completely closed, and there is a sudden onset of severe eye swelling, eye pain, photophobia, tearing, headache, sharp decrease in vision, eyeball as hard as a stone, conjunctival congestion, accompanied by systemic symptoms such as nausea and vomiting. After an acute attack, the patient may enter a chronic stage with persistent damage to the optic nerve, until the optic nerve is severely damaged and vision is reduced to an absolute stage where there is no light perception and it cannot be reversed.

2. Chronic angle-closure glaucoma

The age of onset is over 30 years old. This type of attack usually has obvious triggers, such as emotional excitement, visual fatigue, excessive use of eyes and brain, long-term insomnia, habitual constipation, women during menstruation, or improper local or systemic medication, etc., which can be triggered by dry eyes, fatigue, discomfort, distension and pain, blurred vision or decreased vision, halo vision, dizziness, insomnia, and high blood pressure, which can be relieved after rest. Some patients may become blind without any symptoms. During examination, the intraocular pressure may be normal or fluctuating, or not too high, 20-30 mmHg. The fundus may be normal in the early stage. This type is most easily misdiagnosed. If this happens repeatedly and the anterior chamber angle closes, fulminant glaucoma may develop.

There are four early symptoms: 1. Frequent feeling of eye fatigue and discomfort. ② Eyes often feel sore and swollen, which will be relieved after rest. ③ Blurred vision, myopia or presbyopia suddenly worsens. ④ Eyes often feel dry.

3. Primary open-angle glaucoma

It mostly occurs in people over 40 years old. 25% of patients have a family history. The vast majority of patients have no obvious symptoms. It is often not discovered until the disease develops to the late stage and visual function is severely damaged. Although the patient's intraocular pressure increases, the anterior chamber angle is always open.
