Glaucoma may not be familiar to everyone.
This disease is the second leading cause of blindness in the world after cataract, and glaucoma has always been a disease that threatens human visual health.
Glaucoma is a disease in which the optic nerve is damaged due to excessive pressure in the eye due to various reasons.
Simply put, the pressure inside the eyeball is too high and the optic nerve is compressed, resulting in symptoms such as decreased vision and visual field defect.
A woman who drinks 8 glasses of water a day causes blindness?
Recently, a piece of news is surprising.
Ms. Liu in Changsha, Hunan heard that drinking more water is good for physical and mental health, and it can also moisturize and beautify the skin, so she insisted on drinking eight glasses of water every day. As a result, on the third day, Ms. Liu found herself Eye pain, but also vomiting, dizziness and other phenomena.
After detailed examination by the doctor, it was found that acute angle-closure glaucoma was caused by Ms. Liu consuming 1000ml of water in a short period of time.
Wait, is this the curse of drinking eight glasses of water a day? Are the information points captured by the media a little too abrupt these days?
Shouldn’t the point be that the lady was too anxious to drink a lot of water in a short period of time?
Why does drinking water cause glaucoma?
In fact, drinking too much water at one time can cause blood dilution, which reduces plasma osmolarity and increases intraocular pressure , induced glaucoma.
Therefore, for glaucoma patients, it is necessary to avoid drinking a lot of water in a short period of time, and it is best to drink no more than 500ml of water at one time.
What are the early signs of glaucoma?
Glaucoma and a cold seem to be inseparable, but they do not know that in the early stage of the disease, there may be some very similar symptoms, which will make patients misunderstood in treatment.
Acute glaucoma is prone to symptoms such as bloating, dry eyes, and headache, nausea, and vomiting.
And these symptoms are very similar to colds, and even gastroenteritis, which often leads many patients to mistake glaucoma for cold treatment.
These phenomena may be early signs of glaucoma
First, eye pain, vision loss
Glaucoma is one of the most threatening eye diseases for eye health.
After the onset of the disease, the patient’s eyes will have obvious soreness and swelling, accompanied by eye pain and other manifestations, and before the disease is not relieved , can also lead to a significant loss of vision.
And these manifestations are fundamentally different from colds, especially after a cold, it will not affect vision at all, which is also an important basis for judging whether glaucoma is a cold.
Second, family inheritance, hard eyeballs
From a medical point of view, although the cause of glaucoma is still unclear, it is certain that it is closely related to family inheritance.
If someone in the family has glaucoma, the chances of others in the family getting glaucoma are especially high.
In addition, after the onset of glaucoma, there is also a prominent manifestation of “hardening of the eyeball”. These adverse manifestations are very different from cold symptoms. Therefore, it is necessary to seek medical examination in time, and then actively treat.
Can weather change cause glaucoma?
Acute glaucoma attacks can actually occur for many reasons.
In addition to the well-known familial inheritance, it may also be closely related to emotional agitation, or mydriasis caused by unknown factors, as well as poor diet and weather effects.
These factors can affect the nerve and blood vessel health of the eye, which can lead to glaucoma disease.
In particular, weather changes are closely related to the occurrence of glaucoma. From a medical point of view, weather changes will affect the central nervous system for thermoregulation, and in this case, the autonomic nerves will continue to interfere blood pressure, which in turn can lead to increased intraocular pressure.
And intraocular pressure change is an inevitable factor in the occurrence of glaucoma, so when the weather changes, we must actively prevent the occurrence of glaucoma.
A patient with glaucoma, what details do you need to pay attention to on a daily basis?
For glaucoma patients, it is important to control changes in eye pressure.
In addition to taking the medicine as prescribed by the doctor, it is also necessary to review regularly, and avoid drinking large amounts of water at one time, and avoid drinking water only when you are thirsty.
Also, try to stay in the dark as little as possible, reduce the number of times you go to the cinema, and wear as little or as little sunglasses as possible.
Of course, it is also necessary to maintain a balance of mind and not be too excited, so as not to be excited, the pupils will be dilated and glaucoma will be induced.
