Eye distension and pain, sharp drop in vision may be glaucoma attack. Glaucoma is an eye disease with intermittent or continuous increase of intraocular pressure. Sustained high intraocular pressure can cause damage to all parts of the eyeball tissue and visual function. If not treated in time, the visual field can be completely lost and blind. Glaucoma is one of the three leading causes of blindness in human blindness. The incidence rate of the total population is 1% and 2% after 45 years old.
Eye distension and pain, eyesight plummeting, see a doctor immediately
How much do you know about glaucoma? Recently, the ophthalmology branch of the Chinese Medical Association published the "glaucoma Cognition Survey". The survey data show that the public's awareness of glaucoma is seriously insufficient. 73.5% of the respondents do not know what glaucoma is. Even if they do, more than 85% of the respondents do not know that diabetes and high myopia are high-risk factors.
Professor of Ophthalmology of the Chinese Medical Association points out that glaucoma is a "invisible killer" who keeps a low profile but has a strong attack on the eyes. It can cause irreversible visual damage, and the longer the damage, the greater. Only timely detection and treatment, it is possible to keep vision.
In addition, Japanese researchers have found that patients with glaucoma have higher intraocular pressure when they sleep at night than during the day, which increases their risk of getting worse, according to a US website. At present, doctors usually measure the intraocular pressure of glaucoma patients in the daytime, and most patients use sitting posture. But when people lie down, the intraocular pressure usually increases, which will undoubtedly increase the resistance of aqueous humor discharge.
The researchers stressed that it is not enough to measure intraocular pressure only in the daytime, and it can not accurately determine the risk of blindness in glaucoma patients, so different postures of patients should be considered comprehensively. In addition, when glaucoma patients sleep, they should avoid supine position as far as possible, and take lateral position, which can also effectively reduce the pressure of aqueous humor on the eyes.
Don't let the misunderstanding delay your eyes
In addition, experts especially emphasize that there are three misunderstandings about glaucoma. If we don't pay attention, it will seriously affect its treatment.
Misunderstanding 1: glaucoma is a senile disease. People may have glaucoma in their life, so it is not the exclusive of the elderly. It is only with age that the incidence rate is higher. Over 40 years old, family history of glaucoma, diabetes, hypertension, high myopia and other groups are high risk groups of glaucoma.
If the patients belong to the high-risk group of glaucoma, once they find eye pain, eye distension, acute decline of vision, unexplained migraine, accompanied by nausea, vomiting and iridescence (i.e. seeing a rainbow like halo outside the light), they should suspect the possibility of glaucoma.
Myth 2: Glaucoma does not lead to blindness. 50% of the world's blind people are blind due to glaucoma. The visual impairment caused by glaucoma is mainly manifested as visual field narrowing or defect, and it will be completely blind without active treatment.
Mistake 3: see a doctor when you have symptoms. Glaucoma is known as the "invisible killer" because its early symptoms are not obvious and easily confused with other diseases. Healthy people should have at least one comprehensive glaucoma examination when they are 35-40 years old, and keep it once a year after that.
After reading the above content, you should have some understanding of the problem that eye swelling and pain, sharp drop of vision may be glaucoma attack. More topics about eye health will be introduced in the following article. Welcome to check. Wish you a happy life!
