Many glaucoma patients, especially men, generally have a habit of smoking and drinking alcohol, with most patients smoking 10-20 cigarettes a day and some even smoking 2 packs a day; drinking alcohol is also uncontrolled, drinking every day, drinking meals, and often getting drunk. Excessive drinking of high concentrations of alcohol may damage the optic nerve, especially in patients with glaucoma, and can seriously affect the prognosis. 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 the damage to the optic nerve in patients with glaucoma. 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 a small amount of alcohol can make the capillary dilation in the face of those who are red in the face after drinking alcohol, and the blood vessels that nourish the optic nerve may also expand, thus increasing the blood supply to the optic nerve and slowing down the glaucomatous optic nerve damage. You can’t drink too much because when you drink too much, especially when you’re drunk, your whole body’s blood vessels are constricted, such as those who are pale after drinking (vasoconstricted), sprinkling the essence makes the blood in the face constrict, reducing the blood supply to the optic nerve, thus aggravating glaucomatous optic nerve damage. Therefore, it is best not to drink sprinkles or abstain from alcohol for glaucoma patients who have a live interview and a white face after drinking. For patients who have just had anti-glaucoma surgery, it is best not to drink alcohol because the vasodilatation after drinking alcohol can lead to post-surgical wound bleeding.
