Age Related Macular Disease (AMD)
What is the disease?
AMD is a chronic eye condition that affects the centre portion of the retina. Progressive and central blurring of vision which usually affects both eyes
“Wet” and “Dry” type
Wet Type : eventually leads to blurring of vision
“Dry” Type : can cause loss of vision
Who Gets it?
Higher risk for those 50 and above. Other risk factors include : family history of AMD, high blood pressure, smoking and sunlight exposure.
Why is it important?
AMD can cause irreversible blurring of the vision and tend to affect both eyes
Most common cause of visual impairment amongst older age, approximately affecting close to 300 million people by year 2040
Why screening is essential?
AMD is asymptomatic in the early stages and can affect both eyes.
A simple screening photograph can detect yellowish deposits (drusen), thinning of the retina (retinal pigment epithelium atrophy), scarring, bleeding and swelling of the retina.
Early “dry” AMD will require follow-up to monitor condition
Advanced AMD in one eye can be treated with supplement tablets to prevent progression
"wet" AMD will be treated by a ophthalmologist, early treatment can help prevent further visual loss.
