Headache, nausea and vomiting may not be gastrointestinal diseases, so it is necessary to measure intraocular pressure.

Many people's first reaction is a cold or gastrointestinal disease. It may also be an eye disease-acute angle-closure glaucoma. Glaucoma is mainly divided into three categories: primary glaucoma, secondary glaucoma and congenital glaucoma. The cause of acute angle-closure glaucoma is affected by irritant factors, resulting in a sudden increase in intraocular pressure in one eye. Symptoms such as eye distension, blurred vision, hemiplegia, nausea and vomiting may occur in severe cases, and the attack is greatly affected by the patient's own eye structure, family heredity and other factors. when there are orbital discomfort, sore eyes, slightly blurred vision and other conditions, it may be a small attack of angle-closure glaucoma. Even if the symptoms are relieved after a small attack of glaucoma, sometimes a simple laser surgery (laser iridotomy) can prevent the recurrence of glaucoma. "Glaucoma is a group of diseases characterized by characteristic optic nerve atrophy and visual field defect. pathological elevated intraocular pressure is the main risk factor.

Headaches, nausea, vomiting... When confronted with these conditions, many people's first reaction is a cold or gastrointestinal disease. In fact, it may also be an eye disease-acute angle-closure glaucoma.

"Glaucoma is mainly divided into three categories: primary glaucoma, secondary glaucoma and congenital glaucoma." According to Hou Xianru, chief ophthalmologist of the people's Hospital of Peking University, primary glaucoma can be divided into two types: closed-angle glaucoma and open-angle glaucoma, and angle-closure glaucoma can be divided into chronic angle-closure glaucoma and acute angle-closure glaucoma.

The cause of acute angle-closure glaucoma is affected by irritant factors, which leads to a sudden increase of intraocular pressure in one eye, bloating pain in one eye, blurred vision, hemiplegia, nausea and vomiting in severe cases. It is common in people over 60 years old, women are more common than men, and attacks are more affected by the patient's own eye structure, family heredity and other factors.

"when there is discomfort in the orbit, sore eyes, and slightly blurred vision, it may be a small attack of angle-closure glaucoma. If you rest in a well-lit environment for 2 hours, most of the symptoms can be relieved by yourself. if there is no relief, you should go to the hospital in time." Hou Xianru reminds that even if the symptoms are relieved after a minor attack of glaucoma, it is necessary to make time for further ophthalmological examination, and sometimes a simple laser surgery (laser iridectomy) can prevent the recurrence of glaucoma.

Glaucoma is a group of diseases characterized by characteristic optic nerve atrophy and visual field defect, and pathological elevated intraocular pressure is the main risk factor. The key to control glaucoma is to control intraocular pressure, avoid further damage to the optic nerve and maintain the original visual function. The National Health Commission has warned that to control intraocular pressure, you should avoid drinking large amounts of water in a short period of time, not more than 200 milliliters at a time; proper aerobic exercise and exercise can temporarily reduce intraocular pressure and promote blood circulation; do not carry out exercises such as lifting barbells to increase the pressure on the chest and abdominal cavity, and avoid playing musical instruments for a long time.

The risk of glaucoma for people over the age of 40 is about 2%. Early screening is very important to prevent glaucoma. "under normal circumstances, patients over the age of 40 who go to the ophthalmology department will usually be examined by their fundus and screened for glaucoma." Hou Xianru said that medicine, laser and surgery are the three ways to treat glaucoma. If some high-risk groups of angle-closure glaucoma are detected as soon as possible and timely intervention through iris laser surgery or cataract surgery can avoid the occurrence of glaucoma to a certain extent.

Hou Xianru advises people to maintain peace of mind, try to maintain a good mood, pay attention to eye hygiene and a good eye environment, read mobile phones and books in a well-lit environment, and avoid excessive eye use.
