Macular degeneration FAQs

One in seven Australians over the age of fifty has some evidence of macular degeneration,¹ so it’s probably much more common than you realise.

While anyone can develop macular degeneration, available data suggests that you have a higher risk if you smoke or have a family history of the condition.

It’s extremely important that you get your eyes checked regularly, particularly if you are in a high-risk group.

Regular eye checks after the age of 50 are important. If you have difficulty reading with your glasses, distinguishing faces, or start to see dark or empty patches in your central vision, get your eyes checked immediately.

There are also simple home tests that can indicate if you have any visual changes worth investigating, such as noticing distortion in door frames and tiles.

Prescription glasses can bend light to help it focus on the retina, but they can’t correct any damage in the retina itself.

The forms of macular degeneration that affect younger people are very rare and usually caused by a specific gene defect.² The most common form is Stargardt’s Disease, which may develop from 10 years of age (although vision loss may not occur until in your twenties or thirties).³

Knowing your family history in relation to eye diseases is extremely helpful.

The advanced stage of macular degeneration can be divided into two types:

1. Dry macular degeneration (also called atrophic) is the most common type. Here the macular tissue thins (atrophies) and eventually stops functioning properly. Vision loss is insidious and gradual.
2. Wet macular degeneration (also called neovascular or exudative) affects about 10% of people with advanced AMD. Abnormal blood vessels grow beneath the macula and can leak fluid or bleed, causing the macula to swell. Vision loss is sudden and more noticeable than with dry AMD.
