What is Age-related Macular Degeneration?
Different types of age-related macular degeneration
Macular degeneration is an ageing process occurring in the retina which evolves from an initial stage to early, intermediate and advanced forms of the condition
Advanced AMD – Dry or atrophic form
The dry form of advanced AMD occurs in the final stages of retinal ageing. The drusen affect the macula to such a degree that they cause irreversible lesions which impair accurate sight (or central vision).
Advanced AMD – Wet or exudative form
In some cases, the atrophy is accompanied by abnormal growth of blood vessels located behind the macula, resulting in a distorted image.
The effect of drusen on vision can vary, from practically unchanged to a gradual loss of central vision acuity.
Advanced forms can lead to scarring in the centre of the macula provoking an irreversible loss of central vision.
