Age related macular degeneration

 

Age-related macular degeneration (AMD) is a condition characterized by

the deterioration of the macula. Macular is derived from the Latin word,

macula, meaning spot. The macula is the central and most vital area of

the retina, providing the clearest, most distinct vision needed, for

example, in seeing fine detail, reading, driving, and recognizing facial

features.

 

There are two forms of macular degeneration: atrophic (dry) and

neovascular (wet). Both forms of the disease may affect both eyes

simultaneously. Vision can become severely impaired, with central vision

rather than peripheral vision affected. The ability to see color is

generally not affected, and total blindness from the condition is rare.

 

As lutein and zeaxanthin are the essential pigments within the macula,

it is critical to replenish them as they become depleted through the

aging process. Consumption of foods rich in these substances is

especially important since they have a direct affect on macular pigment

density. When the pigment in the macula is denser, retinal tearing or

degeneration is less likely. Lutein and zeaxanthin are found in yellow

or orange vegetables, in dark leafy greens, and in fruits with yellow or

orange hues. Egg yolk is a good source of lutein. Dietary supplements of

lutein and zeaxanthin are recommended.
