AMD can be split into 2 main types: ’Wet’ and ‘Dry’.
NB AMD is not related to wet (watery) or dry eyes.
DRY AMD the most common form of AMD and develops very slowly. In fact, Dry AMD may take many years to reach its end stage, when it leaves a dark / blank patch in the central vision.

However, a small percentage of those with Dry AMD will also develop Wet AMD so if you are affected by this condition, you must report any changes in your vision as soon as possible to your Consultant or Optometrist
Around 10-15 % of people with AMD have Wet AMD, which, for a small percentage of people, will have started as Dry AMD.
This condition occurs when the cells in the macula stop functioning correctly and new blood vessels develop (neo-vasularisation) in an attempt to fix the problem. Unfortunately, these blood vessels start to leak fluid into the macula – hence the term ‘Wet’. This process causes damage to the macula in the form of scar tissue, resulting in permanent blurring of your central vision.
This condition can happen quickly so needs to be assessed and treated as soon as possible to reduce the amount of scar tissue that develops.
