Choroidal Nevus in the United States Adult Population

Among US adults, the prevalence of choroidal nevus located within two 45° areas centered on the macula and optic disc is 4.7%. The prevalence increases with age, is highest among whites (5.6%), is lowest among blacks (0.6%), and has been previously under-recognized among Hispanics (2.7%). Extrapolating to the entire fundus, the true prevalence of choroidal nevus is even higher but difficult to accurately estimate. Possible associations with cardiovascular, renal, autoimmune, and occupational risk factors warrant further investigation.
