There are many advantages to eating a healthy diet. In the long-term this may affect your risk of cardiovascular disease, which in turn is indirectly linked to glaucoma. There is little evidence that suggests that any dietary supplementation affects the course of glaucoma. There are hundreds of randomised controlled trials (the gold standard in scientific research) that demonstrate the benefit of glaucoma medications in controlling eye pressure, but there is no convincing data as yet on the use of dietary supplementation.
