Glaucoma is the name given to a group of diseases where loss of vision occurs due to progressive damage to the optic nerve. If left untreated, it may result in total blindness.
Glaucoma is known as the ‘sneak thief of sight’ because there are no symptoms associated with the disease until late stages of the disease where significant vision loss has already occurred. Diagnosis consists of having regular eye examinations which include a pressure measurement (usually every 2 years for patients over 40), to enable early detection of possible problems.
Lower your risk of Glaucoma
- A healthy lifestyle that includes regular exercise and a nutritious diet benefits overall physical and mental well-being, as well as the eyes. Eat a varied and healthy diet. There is no scientific evidence suggesting that certain vitamins and minerals prevent glaucoma or delay its progress. However, carotenoids (especially lutein and zeaxanthin), antioxidants (vitamins C and E), vitamins A and D, zinc and omega-3 fatty acids may all contribute to better vision.
- Carotenoids are found in dark green, yellow and orange fruits and vegetables, including spinach, broccoli, green beans, papaya, oranges, mango, sweet potato, corn, peaches and apricots.
- Vitamin C is found in citrus fruits, tomatoes, strawberries, leafy greens, sweet and white potato, broccoli and capsicum.
- Vitamin A is found in liver, carrots, sweet potato, mangoes, milk and egg yolks.
- The main dietary sources of vitamin D are cod liver oil, ‘oily’ fish, fortified milk and cereal and egg yolks.
- Zinc can be found in oysters, red meat, poultry, beans, nuts, wholegrains and dairy products.
- Omega-3 fatty acids are found in salmon, sardines, walnuts and flaxseed oil.
