Beware of glaucoma attacks

Why sudden changes in temperature can lead to acute attacks of glaucoma

Low winter temperatures

The temperature fluctuates greatly. At this time, people with glaucoma risk factors/glaucoma patients are affected by this, which can induce sudden closure of the aqueous humor outlet angle, obstructing the outflow of aqueous humor and leading to a sudden attack of glaucoma.

Large temperature difference between indoor and outdoor

It is cold outside in winter and warm inside. If glaucoma patients suddenly experience a temperature change from hot to cold when they go out, it is easy to induce an acute attack of glaucoma.

Drink plenty of water

The weather is dry in winter, and especially under the influence of air conditioning or heating, water loss occurs. If you have dry mouth and tongue and drink a large amount of water at one time, the amount of aqueous humor in the eye increases, which causes increased intraocular pressure and the possibility of an acute attack of glaucoma.

Related to behavioral habits

Lying down for a long time playing with mobile phone or reading, especially playing with mobile phone after turning off the lights at night , is more likely to induce an acute attack of glaucoma.

Glaucoma ≠ high intraocular pressure

It can be said that high intraocular pressure is the main risk factor for glaucoma, because most glaucoma is caused by increased intraocular pressure leading to damage to the optic nerve, but there are also two other situations.

Some glaucoma patients have normal intraocular pressure, but have already suffered glaucomatous optic nerve damage , which is called "normal pressure glaucoma" . Some people have high intraocular pressure, but have not yet suffered glaucomatous optic nerve damage, which is called "ocular hypertension". Studies have found that a small number of people with ocular hypertension will eventually develop glaucoma.

Therefore, not all glaucoma patients have high intraocular pressure, nor does it mean that normal intraocular pressure does not mean glaucoma. Intraocular pressure is not the only criterion for diagnosing glaucoma, but also whether the optic nerve is damaged.

How to detect glaucoma early and avoid it

Ophthalmoscopy and intraocular pressure examination should be routine examinations for all people during physical examinations, especially for those with a family history of glaucoma and those at high risk of glaucoma. After the age of 50, we should examine the fundus and intraocular pressure once a year.

Keep your emotions stable and avoid excessive excitement, anxiety and excitement. Many acute attacks of glaucoma are related to emotional excitement.

Maintain a regular lifestyle; avoid staying in the dark for a long time or wearing sunglasses for a long time.

It is not advisable to work with your head down at a desk for a long time.

Eye drops containing hormones should be used in a standardized manner under the guidance of a physician. Long-term use of such eye drops can lead to steroid-induced glaucoma.

If you suddenly experience blurred vision accompanied by symptoms such as eye swelling, headache, nausea, and vomiting, you should be alert to whether it is an acute attack of angle-closure glaucoma.

The glaucoma specialist at the Aier Eye Hospital affiliated to Wuhan University reminds that the optic nerve damage caused by glaucoma is irreversible. For glaucoma patients, "it's like adding a door in front of your eyes. The door gets smaller and smaller, and you don't know when it will be completely closed." Therefore, "early screening, early detection, early diagnosis, early treatment, and lifelong follow-up" are very important to save the visual function of glaucoma patients!
