Leek is a vegetable that is rich in various vitamins and is very good for the body, but it is a hot vegetable that is easily indigestible after eating it. Some patients with glaucoma, like acute angle-closure glaucoma, have headaches, dizziness, nausea and vomiting when they have an attack, so they can’t eat leeks, and then eating leeks will aggravate their stomach discomfort and promote vomiting or gastric distention, so they need to eat liquid food that is easy to digest and absorb. Glaucoma is mainly treated for its cause, to bring down the intraocular pressure of glaucoma, so that it is treated symptomatically. Glaucoma treatment generally relies on medication and surgery, and food can only promote recovery, nutrition and reduce the discomfort of glaucoma.
