Diet and Nutrition for Glaucoma: Protecting the Optic Nerve
While glaucoma cannot be cured through diet alone, research shows that certain foods and nutrients can support optic nerve health, reduce oxidative stress, and may help lower intraocular pressure. A glaucoma-friendly diet is an important complement to medical treatment.
Overview
Diet and Nutrition for Glaucoma: Protecting the Optic Nerve
Uses & Indications
Glaucoma causes progressive peripheral vision loss
Diet cannot reverse damage but may slow progression
High IOP responds poorly to caffeine — limit coffee intake
Vascular dysregulation worsened by poor diet
Oxidative stress damages retinal ganglion cells over time
Nitric oxide from leafy greens may help lower IOP naturally
How to Use
Oxidative damage to retinal ganglion cells accelerated by poor antioxidant intake
High sodium intake can raise blood pressure, affecting optic nerve blood flow
Caffeine transiently raises IOP — relevant for some glaucoma patients
Omega-3 deficiency linked to increased IOP in some studies
Inadequate vitamin B3 (niacin) linked to glaucoma risk
Excessive alcohol consumption may raise IOP
Benefits & Effectiveness
Eat nitrate-rich vegetables (spinach, kale, beets) — may lower IOP
Include omega-3 fatty acids (fish oil, flaxseed) to support nerve health
Antioxidant-rich berries, coloured vegetables to reduce oxidative stress
Limit caffeine if your IOP is sensitive to coffee
Maintain healthy weight — obesity associated with higher IOP
Avoid excessive fluid intake in short periods (raises IOP temporarily)
Consider ginkgo biloba extract — may improve optic nerve blood flow
