Glaucoma refers to an ophthalmic disease caused by atrophy of the optic nerve caused by high intraocular pressure, resulting in visual field defects and even eventually blindness. The definition of glaucoma has been updated. In the early days, people thought that the high intraocular pressure was glaucoma. Later, it was found that even normal people may have high intraocular pressure, and some patients with glaucoma have normal intraocular pressure. So the definition of glaucoma in textbooks changes as people become more aware of the disease. Common features of glaucoma are optic atrophy and visual field defects, and pathological increase in intraocular pressure is one of the important risk factors. The reason why it is called "blue light" is because the pupil will produce cyan reflection when the light is used to illuminate the eyes of the terminal patient.
Glaucoma is a major “macro†of eye diseases, with 40-60 million glaucoma patients worldwide, and China accounts for nearly half. At present, the treatment rate of glaucoma in China is only 10%-20%, and 80%-90% of patients do not know that they have glaucoma. The glaucoma knowledge in western developed countries is relatively high, and the detection rate has reached 70%.
- Clinical symptoms of glaucoma
1 often feels eye fatigue discomfort
2 eyes often sore, will be relieved after a break
3 blurred vision, myopia or presbyopia suddenly deepened
4 eyes often feel dry
- What kind of food is good for glaucoma?
Eating honey can lower the intraocular pressure : after the honey is taken, the blood osmotic pressure can be increased to reduce the intraocular pressure.
Eat foods rich in vitamins E and B: such as malt, vegetable oil, whole grains, jujube, lean pork, animal liver and so on.
Foods that eat water: Chixiaodou, melon, watermelon, loofah, day lily, etc., can reduce the retention of aqueous humor, often used as a glaucoma auxiliary treatment food.
Avoid heavy drinking water and caffeinated drinks: Drink plenty of water in a short period of time, which may lead to a significant increase in intraocular pressure, and it is not advisable to drink more coffee and tea.
- Simple and easy way to check:
Many patients have symptoms such as blurred things, eye pain, and visual fatigue, which are often overlooked because they are similar to other eye diseases. It is often too late to wait until the patient finds the symptoms of glaucoma. It is most important to do early screening!
To prevent glaucoma, as long as three tests are done: slit lamp, ophthalmoscopy, and intraocular pressure test, you can quickly check whether the patient has glaucoma, and it will not be in five minutes. For example, the Canon automatic tonometer can quickly and accurately measure intraocular pressure and print in time. At the same time, it is also equipped with an external fixation lamp, which is also very effective for patients with central vision defects.

Question 1: In daily life, such as netizens and young people surfing the Internet, people who need to use a lot of eyes at work will be more likely to suffer.
Glaucoma?
Answer: This is not directly related. Because glaucoma has genetic susceptibility, but the onset of disease is still determined by the internal and external environmental effects of the day after tomorrow. Genetic factors are the first, and the probability of glaucoma in high myopia is greater, but it is not a decisive factor. At the same time, the increase in degree does not mean that glaucoma is more likely to occur.
Question 2: What is the core of glaucoma treatment?
Answer: Glaucoma is the damage of optic nerve caused by high intraocular pressure. The first treatment is also to reduce intraocular pressure. So the first principle of glaucoma treatment so far is to reduce intraocular pressure, reduce the intraocular pressure to a safe level, optic nerve damage no longer progress, such as the original progress is 10% per year, by reducing the intraocular pressure, the optic nerve damage To 5%, 3%, 2%, or even no progress at all, this is called success. Ophthalmology treatment is generally eye drops, and now there are many drugs that can control intraocular pressure.
Question 3: What tests are needed for early prevention of glaucoma?
Answer: Timely monitoring of intraocular pressure is very helpful in the diagnosis of early glaucoma. Canon automatic tonometer is a very good device, often used for glaucoma screening work. On the one hand, it is small and portable, accurate measurement, and it is fully automatic non-contact design, no harm to the patient. On the other hand, this tonometer can make repeated and rapid measurements on many patients in a short period of time. If the tonometer is combined with a fundus camera, the effect will be better, and the patient can get clear fundus photos in just a few minutes. And you can connect to the doctor immediately.
