of Macular Degeneration

Cross Section of the Macula
with the Dry Form of MD

With age in certain people the blood vessels supplying the macula and Bruch's membrane harden.

Transport of vital oxygen into, and waste materials/fluids out becomes more difficult. Old cells in the RPE are less easily disposed of leading to accumulation of broken down material that contributes to drusen.

As drusen continues to accumulate, the RPE cells are lifted further and further away from their blood supply, progressively impairing the transport of vital substances to the macular area of the retina. This causes the central point of the retina (macula/fovea) to bow upwards causing loss and distortion of vision.
