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. Today, we will introduce the contraindications to the daily diet of patients with pigmentary glaucoma. 1, avoid strong tea, coffee, strong tea, coffee have a sympathetic nerve excitation, sympathetic excitement after the pupil dilates, atrial circulation is blocked, resulting in an increase in intraocular pressure induced glaucoma acute attack, so try to avoid. 2, avoid drinking a lot of water after drinking a lot of water, due to the large amount of water absorbed by the body, the intraocular atrial aqueous increased, glaucoma due to filter curtain dysfunction, atrial aqueous drainage abnormal, will cause an increase in intraocular pressure. Therefore, glaucoma patients should pay attention to control the amount of water, generally do not drink more than 500 ml each time, can take a small number of times the method. 3, avoid smoking, alcohol open-angle glaucoma patients and patients with high intraocular pressure, smoking increases intraocular pressure, in order to protect the visual function, glaucoma patients should quit smoking. And drinking alcohol is not good for closed-angle glaucoma, drinking strong alcohol will cause the capillaries of the eye to dilate, eye congestion is aggravated, easily lead to acute glaucoma attack.
