Trabecular meshwork pigmentation is a manifestation of the clinical diagnosis of pigmentary glaucoma. Pigmentary glaucoma is a secondary open-angle glaucoma caused by pigmentation of the anterior segment of the eye. It is usually confused with iris pigment loss and uveitis symptoms and is usually treated with medication first, followed by laser treatment, and finally surgery is considered. So what should patients pay attention to in their diet? Honey is effective in treating glaucoma. Patients with acute glaucoma can have their symptoms relieved by taking 100 ml of honey. Glycerin has the same healing effect. 100 ml at a time orally can bring down the IOP rapidly. Honey and glycerin are hypertonic agents and when taken, they increase the osmotic pressure of the blood to absorb water in the eye and lower the intraocular pressure. High intraocular pressure in glaucoma patients is due to the accumulation of excessive water in the eye, and the use of aqueous facilitation drugs can increase atrial water flow and reduce atrial water retention. Therefore, patients with glaucoma can usually consume aqueous-supportive adzuki beans, enoki mushrooms, watermelon, loofah, etc. Don’t take big supplements in the early postoperative period In glaucoma surgery, the doctor will make a filtering channel inside and outside the patient’s eye, and this filtering channel is the wound that is related to the success of the surgery. In the 3 months after surgery, the surgeon will try to keep this wound from healing. If the patient often eats high-protein foods or even takes some herbs that promote tissue healing, it may lead to scarring of the filtration channel and cause the failure of the surgery. Therefore, under the premise of ensuring basic nutrition, glaucoma patients should not take large supplements after surgery, and should eat a light diet with some low-protein foods. In addition, glaucoma patients should also pay special attention not to take ginseng, American ginseng, American ginseng, party ginseng and other ginseng supplements and blood-stasis activating drugs after surgery, because these supplements may lead to anterior chamber bleeding. Drink water when a small number of times Glaucoma patients have a weaker capacity for water loading than normal people. In a normal person who drinks 500 ml of water in one gulp, the intraocular pressure may rise by 3 to 5 mm Hg. If a glaucoma patient may rise 6 to 8 mm Hg. If glaucoma patients often drink more than 200~300ml of water in one gulp, the IOP burden will be very heavy and affect the effectiveness of medication. Therefore, patients with glaucoma should not drink a lot of water at one time, but should drink less and in several times each time.
