Macular degeneration is an age-related condition that affects individuals later in life. It causes a gradual deterioration in the sharpness of the central vision. The problem starts in a section of the retina called the macula. This part of the retina is responsible for fine resolution vision. There are two categories of macular degeneration: dry and wet.

Dry macular degeneration is a slow process, which initially has minimal effect on the vision. Over time it can cause a gradual deterioration in the quality of the central vision.

Wet macular degeneration is a more severe form of the disease and can cause a more sudden deterioration in the central vision.
