FAQs about Age-related macular degeneration (AMD)



What is a Amsler grid test?

It is a screening test to detect vision problems resulting from age-related macular degeneration (AMD).


What is Age-related macular degeneration (AMD)?

"Age-related" means that it often affects older people. "Macular" means it affects a part of your eye called the macula.
AMD is a common condition affecting our central vision and is the leading cause of vision loss for people age 60 and older. It doesn’t cause complete blindness, but can make it challenging to see faces, drive, or do close-up work.

What are the symptoms of AMD?

Early Symptoms: None

Later Symptoms:

  1. Blurring of the central vision (the ability to see details straight ahead).
  2. Missing areas of vision
  3. Distorted vision (e.g. straight lines appear wavy)
  4. Problems differentiating between similar colours
  5. Unable differentiate levels of brightness
  6. Slow recovery of vision after seeing bright light

If you have late AMD in only one eye, you may not notice anything!

How rapid is the progression of AMD?

Symptoms may be gradual or rapid in onset.

It happens slowly in some people and they may not experience vision loss for a long time. For others, AMD progresses faster.
