Key Facts about Macular Degeneration
by: Optometrist Noosa on
Only a complete eye test can detect the early signs of Macular Degeneration, Australia's leading cause of blindness and severe vision loss. All Australians over the age of 50 years should have an eye test and make sure their macula is checked. The macula is the central part of the retina, which is the light-sensitive tissue at the back of the eye. The macular processes all central visual images and is responsible for the ability to drive, see colours clearly, read and recognize faces.
Fast facts about macular degeneration:
- A complete eye test can save your sight
- 1 in 7 Australians over 50 have some evidence
- 50% chance if direct family history
- You can have the early signs without knowing
- Diet & lifestyle supports good macular health
Noosa residents are urged to visit an independent Optometrist equipped with Macular Degeneration diagnostic equipment. At Noosa Optical, our 360 degree eye consultation includes a high definition macula check which is crucial for the detection of macular degeneration which occurs at the back of the eye. You can have the early signs without knowing, even before symptoms occur.
What are the types of macular degeneration?
There are two types, dry and wet. The dry form results in a gradual loss of central vision. The wet form is characterised by a sudden loss of vision and is caused by abnormal blood vessels growing under the retina. Immediate medical treatment is essential if symptoms occur.
Risk factors of macular degeneration include:
- Age (particularly over 50yrs)
- A direct family history means you have a 50% risk factor
- Smoking increased your risk by 3-4 times
- Sun exposure, including when young
Almost 1.25 million Australians over 50 have some evidence of macular degeneration, making it Australia’s leading cause of severe vision loss and blindness. Without appropriate prevention and treatment measures, this number is set to increase to 1.7 million by 2030.
- Difficulty with reading or any other activity with fine vision
- Distortion where straight lines appear wavy or bent
- Distinguishing faces becomes a problem
- Dark patches or empty spaces appear in the centre of your vision
What treatments are available for macular degeneration?
Treatment options depend on the stage and type of macular degeneration. Current treatments for the wet form have been shown to be highly effective in saving sight. However, early detection, correct diagnosis and timely treatment is critical.
The very early signs of macular degeneration can now be easily identified with advanced equipment. Early diagnosis gives the best opportunity to save sight by adopting nutrition and lifestyle practices and timely access to treatment.
If you notice any sudden changes in your vision it is essential to seek medical attention urgently. The ‘wet’ form of macular degeneration can progress very quickly and requires rapid treatment to save sight. An Amsler grid can also be used to self monitor for changes in vision between professional appointments and is available free from Noosa Optical.
