Headaches, eye pain recurrences, blurred viewing, narrowed field of vision, lighting and glare... The "vision" of glaucoma patients is very different from that of ordinary people, especially in winter, when glaucoma is high, which is more likely to affect people's lives.
1. Why is it easy to induce glaucoma in winter?
In winter, the temperature is cold, the temperature drops, and the cold will seriously stimulate sympathetic excitement, dilate the pupils, lead to narrowing of the atrial angle, and block the outflow of aqueous humor, causing the aqueous humor to overflow and the intraocular pressure to become high, resulting in a sudden onset of glaucoma.
Winter air is relatively dry, some people will drink a lot of water, a lot of drinking water will make the aqueous humor significantly increased, resulting in increased intraocular pressure, the occurrence of glaucoma.
2. Early symptoms of glaucoma
Some patients with glaucoma have no obvious symptoms in the early stages, or only a little headache and bloating, which is often considered to be no good rest or eye fatigue. By the time I went to the hospital to be diagnosed with glaucoma, I had already experienced irreversible optic nerve damage and visual field defects.
The first symptom of glaucoma in the other part is usually iris or blurred vision. Rainbow vision refers to the appearance of a rainbow-like halo when looking at a light source. Blurred vision is more common when people are more emotionally excited or at dusk, and this symptom generally does not last long, and it will recover in a few minutes or more than half an hour.
3. How should glaucoma be prevented in winter?
■ Maintain emotional stability and avoid nervousness and excessive excitement;
■ Try not to go out when strong cold air comes, so as to reduce the irritation to the eyes;
■ Do not stay in dimly lit places for a long time;
■ Quit smoking and alcohol, and do not drink strong tea, coffee and other irritating foods;
■ Combine work and leisure to ensure adequate sleep;
■ People with a family history of glaucoma should visit the hospital regularly for examination.
