To estimate the prevalence and distribution of age-related macular degeneration(AMD) in the United States by age, race/ethnicity, and gender.

Summary prevalence estimates of drusen 125 µm or larger, neovascularAMD, and geographic atrophy were prepared separately for black and white personsin 5-year age intervals starting at 40 years. The estimated rates were basedon a meta-analysis of recent population-based studies in the United States,Australia, and Europe. These rates were applied to 2000 US Census data andto projected US population figures for 2020 to estimate the number of theUS population with drusen and AMD.

The overall prevalence of neovascular AMD and/or geographic atrophyin the US population 40 years and older is estimated to be 1.47% (95% confidenceinterval, 1.38%-1.55%), with 1.75 million citizens having AMD. The prevalenceof AMD increased …
