Glaucoma, presumably everyone does not feel familiar.
This is the second most blinding eye disease in the world after cataracts, and glaucoma has long been a disease that threatens human visual health.
The so-called glaucoma is a disease that causes excessive pressure in the eye for various reasons, resulting in damage to the optic nerve.
Simply put, the pressure in the eyeball is too large, and the optic nerve is compressed, which leads to symptoms such as vision loss and visual field defects.
A woman drinks 8 glasses of water a day, but causes blind eye disease?
Recently, a piece of news is unbelievable.
Ms. Liu of Changsha, Hunan Province, heard that drinking more water is beneficial to physical and mental health, but also moisturizing and beautifying the skin, so she insisted on drinking eight glasses of water every day, and as a result, on the third day, Ms. Liu found that her eyes were swollen and painful, and there was vomiting, dizziness and other phenomena.
After a detailed examination by the doctor, it was found that because Ms. Liu had 1000ml of water in a short period of time, it caused acute angle-closure glaucoma.
Wait, is this the curse of drinking eight glasses of water a day? In these years, is the information captured by the media a little too abrupt?
Shouldn't the point be that this lady drank a lot of water in a short period of time and was too anxious to cause it?
Why does drinking water also cause glaucoma?
In fact, drinking too much water at one time will cause blood dilution, thereby reducing plasma osmolality, causing increased intraocular pressure and inducing glaucoma.
Therefore, for glaucoma patients, it is necessary to avoid drinking water in a short period of time, and the amount of disposable water is best not more than 500ml.
Glaucoma, what are the early phenomena?
Glaucoma and colds seem to be incompatible, but they do not know that in the early stage of the disease, there may be some very similar diseases, which will make patients enter the misunderstanding in treatment.
For acute glaucoma, it is easy to have eye swelling, dry eyes, headache, nausea, vomiting and other symptoms after the onset of the disease.
These symptoms are very similar to colds, and even have similarities with gastroenteritis, which often leads many patients to mistakenly treat glaucoma as a cold.
These phenomena may be an early sign of glaucoma
First, eye pain and decreased vision
Glaucoma is one of the eye diseases that is extremely threatening to eye health.
After the onset of the disease, the patient's eye area will have a significant feeling of soreness, accompanied by eye pain and other manifestations, and before the disease is relieved, it will also lead to a significant decrease in vision.
These manifestations and colds are essentially different, especially after the cold will not affect the vision at all, which is also an important basis for judging whether glaucoma is cold.
Second, family inheritance, the eyeball hardened
From a medical point of view, although the cause of glaucoma is not clear, it is certain that it is closely related to family genetics.
If one person in the family develops glaucoma, the probability of others in the family developing glaucoma will be particularly high.
In addition, after the onset of glaucoma, there is also a prominent manifestation of "eye hardening", these adverse manifestations and cold symptoms are very different, so it is necessary to seek medical examination in time and then actively treat.
Can weather changes induce glaucoma?
In fact, there are many causes of acute glaucoma attacks.
In addition to the well-known familial inheritance, it may also be related to over-agitation, or mydriasis caused by unknown factors, as well as poor diet and weather effects.
All of these factors can affect the nerve and blood vessel health of the eye, which in turn can precipitate glaucoma disease.
In particular, weather changes and the appearance of glaucoma are very closely related, from a medical point of view, weather changes will affect the body temperature regulation of the central nervous system, in this case the autonomic nerve will continue to interfere with blood pressure, which will lead to a continuous rise in intraocular pressure.
The change in intraocular pressure is an inevitable factor in the appearance of glaucoma, so when the weather changes, we must actively prevent the appearance of glaucoma.
What details do glaucoma patients need to pay attention to on a daily basis?
For patients with glaucoma, it is necessary to control the changes in their intraocular pressure.
In addition to taking medication as prescribed by a doctor, it is also necessary to review it regularly, while avoiding drinking a large amount of water at once, and avoiding drinking water when you are thirsty.
Also, try to stay in the dark as little as possible, reduce the number of movies you go to the theater, and wear less or as little sunglasses as possible.
Of course, it is also necessary to maintain a balanced mentality, not too excited, so as not to be excited, the pupils will be dilated, and glaucoma will be induced.
