Many glaucoma patients, especially male patients, have the habit of smoking and drinking, most of them smoke 10-20 cigarettes a day, and even more, some of them smoke 2 packs a day; drinking is also uncontrolled, drinking every day, drinking at meals, and often drinking until drunk. These are the factors that seriously affect the prognosis of glaucoma. The World Health Organization’s slogan for glaucoma patients is “stop smoking and limit alcohol”, which means that for glaucoma patients, it is important not to smoke, but to drink a small amount of alcohol. The nicotine in cigarettes can cause optic nerve vasospasm and optic nerve ischemia, which can accelerate and worsen the damage to the optic nerve in glaucoma patients. For patients who have the habit of drinking alcohol, those who are red in the face after drinking (capillary dilation) can drink a small amount of red wine, 50 ml per day is appropriate, because people who are red in the face after drinking alcohol, a small amount of alcohol can make the capillaries in their face expand, and the blood vessels that nourish the optic nerve may also expand, thus increasing the blood supply to the optic nerve, improving the blood circulation to the optic nerve, and slowing down the glaucomatous optic nerve damage The purpose of the treatment. However, you should not drink too much alcohol, because when you drink too much alcohol, especially when you are drunk, the blood vessels of your whole body are constricted, just like those patients who turn white after drinking (vasoconstriction), because alcohol makes their facial blood vessels constrict, which reduces the blood supply to the optic nerve, thus aggravating glaucomatous optic nerve damage. Therefore, patients with glaucoma who turn blue or white after drinking alcohol are advised not to drink alcohol. However, for those patients who are red-faced after drinking and have had anti-glaucoma surgery, it is best not to drink alcohol, especially early after surgery. This is because the dilatation of blood vessels after drinking alcohol can lead to post-surgical wound bleeding or scar formation in the surgical area. In addition, a sensible diet and lifestyle habits are beneficial not only for glaucoma but more so for physical health.
