Although there is no known direct connection between nutrition and glaucoma, certain foods have been identified that increase the intraocular pressure (IOP) in your eyes and can potentially make glaucoma worse. For instance, trans fatty acids (foods that contain partially hydrogenated oils) can raise cholesterol levels, eventually causing blood vessel damage. Foods containing high amounts of saturated fats can lead to weight gain and other health conditions that worsen glaucoma. Simple carbohydrates can elevate insulin levels, raising the blood pressure and your IOP. Caffeine and alcohol consumption can also raise your IOP. Also, drinking large volumes of water or other liquids at a time may raise the intraocular pressure of your eyes. Medications that contain steroids should also be avoided because steroids can elevate your intraocular eye pressure and worsen the damage to your optic nerve.
Foods that may help prevent glaucoma from worsening include green leafy vegetables, fruits and vegetables high in Vitamin C and A, antioxidant rich foods, complex carbohydrates such as oatmeal, brown rice, quinoa, potatoes, beans, peas and lentils (foods which contain vitamins, minerals, and antioxidants).
