Labelled diagram of the structure of the retina

AMD and ARMD are common abbreviations for "Age-related macular degeneration", which is the most common cause of blindness in the elderly.

Macular degeneration refers to conditions that adversely affect the "macula lutea" (also known as the "yellow spot") on the retina at the back of the eye.

Two types of Age-related macular degeneration are:

  • Atrophic (or dry) AMD
    ... which arises from small blood vessels in the choroid becoming constricted (i.e. too narrow), therefore reducing blood flow to the macula and so resulting in degeneration of the retinal pigment epithelium, and
  • Wet AMD
    ... which is associated with the occurence of abnormal new blood vessels forming from the choroid (behind the retina), then leaking fluids into the retinal pigment epithelium, with the effect of reducing macular function.

Treatment for these degenerative processes is often available. Ophthalmologists can advise what is appropriate in individual cases.
