AMD stands for age-related macular degeneration. It occurs when the macula ages too rapidly.
The macula is the area at the centre of the retina that is responsible for your central vision. When you look at an object, its image is formed on the macula.
AMD can thus lead to a loss of central vision, while usually leaving the peripheral vision unaffected. It is a chronic and progressive disease.
AMD is a condition that is frequently found in the over-65s. It affects the central vision and diminishes perception of fine details (both close-up and from a distance) by either distorting or blurring your vision.
There are two types of AMD: Dry (which develops more slowly) and Wet.
Its symptoms
- Reduced sensitivity to contrasts
- Rapid reduction in visual acuity
- Perceived distortion of straight lines
- Appearance of a black or grey mark that hinders the central vision.
