(Redirected from Senile macular degeneration). Macular degeneration, often age-related macular degeneration (AMD or ARMD), is a medical condition that usually affects older adults and results in a loss of vision in the center of the visual field (the macula) because of damage to the retina.It occurs in dry and wet forms.lthough some macular dystrophies affecting younger individuals are sometimes rarely referred to as macular degeneration, the term generally refers to age-related macular degeneration (AMD or ARMD). The retina is a network of visual receptors and nerves.
Dry Macular Degeneration. The dry (atrophic) type affects approximately 80-90% of individuals with AMD. Its cause is unknown, it tends to progress more slowly than the wet type, and there is notâas of yetâan approved treatment or cure.In dry age-related macular degeneration, small white or yellowish deposits, called drusen, form on the retina, beneath the macula, causing it to deteriorate or degenerate over time.ou can read more about both types of macular degeneration at Macular Degeneration International, Macular Degeneration Partnership, and Macular Degeneration Support, where you can also view a retinal photograph of dry AMD and drusen and a retinal photograph of wet AMD (also called exudative). Tell us what you think.
