What is Macular degeneration ?

  • Age-related macular degeneration (AMD) is an eye disease that affects central vision.

There are two types:

  • dry.
  • wet.

What are the symptoms of Macular degeneration?

Macular degeneration isn’t painful. You may not even notice you have the condition until you experience a loss of vision. AMD affects activities requiring detail, such as reading and writing.

Dry AMD

The more common of the two conditions, dry AMD affects your ability to see fine detail. You may find it difficult to read, use your computer, watch the television, drive, etc. Some people may not realise the change in vision, as it happens so slowly

Wet AMD

Wet AMD involves a sudden and sometimes dramatic decline in your central vision, usually in one eye. Typically, wet AMD develops in people who have already had dry AMD. It is very important that anyone who has unusual symptoms (such as straight lines appearing to be wavy or blurring of the central vision) contacts an optometrist as soon as possible.


What causes age-related macular degeneration?

Dry AMD is caused by the gradual break down of light-sensitive cells in the macula (the central area of the retina at the back of the eye) over several years. Wet AMD is caused by the growth of blood vessels underneath the macula, which can leak or cause scarring.

It is not known why this is, but it tends to happen as people get older.

There are also several risk factors associated with macular degeneration:

  • Smoking
  • Family history
  • Obesity
  • Gender
  • Race
