Macular degeneration accounts for 90% of legal blindness in Australia, and despite it being the leading cause of blindness, most of us don’t know about the function of the macula, what happens when it degenerates and how to prevent it.
Macular disease causes loss of central vision where the finely tuned cells in the centre of the retina become damaged.
We don’t know the cause of age-related macular degeneration, but we do know that there are certain risk factors for the development. Research indicates it may be related to a combination of heredity and environmental factors, including smoking and diet.
There are 2 types including of macular degeneration:
The biggest issue with macular degeneration is that it generally doesn’t have symptoms in the early stages for most people and the only way to reduce the risk of progression is by regular review and advice on diet and lifestyle choices.
It’s important to note 50% of patients that have macular degeneration also have a family member that has been affected with the condition.
If there are risk factors identified in your eye examination, our optometrists will discuss the evidence around adjusting your diet or taking a supplement to include the AREDs II research to minimise progression of early macular degeneration.
Dietary adjustments could include ensuring you have leafy green vegetables every day particularly the darker greens like spinach, kale and broccoli. A handful of nuts (almonds, walnuts or brazil nuts) each week, and a serve of oily fish (salmon, tuna or sardines) 2-3 x/week.
