age-related maculopathy

Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia.

maculopathy, age-related

A condition in which there are large whitish-yellow soft drusen in the macular area and hyperpigmentation or depigmentation of the retinal pigment epithelium associated with the drusen. Small hard drusen may also be present. It occurs most commonly in individuals over 50 years of age and represents the early stage of age-related macular degeneration. The risk of progression of this condition may be decreased by dietary supplements of vitamin C and E, antioxidants (carotenoids such as lutein and zeaxanthin) and minerals (zinc and cupric acid).

The Beaver Dam Eye Study, based in Wisconsin, provided epidemiologic evidence of a significant relationship between extended exposure to the sun and the incidence of early age-related maculopathy (ARM), while a study of watermen in Chesapeake Bay found an increased incidence of severe AMD among those exposed to higher levels of blue and visible light over the previous 20 years.

If supplementation does help prevent or delay AMD, it is likely a small benefit, with confidence intervals compatible with a protective effect not exceeding 10% for preventing age-related maculopathy (ARM) and 25% for preventing AMD (i.e., advanced ARM).
