Abstract:Examination of the eyes of 519 Eskimos in West Greenland revealed preplaques (grey, ill-defined, translucent bands on the sclera anterior to the insertion site of the horizontal recti) in 4% and scleral plaques (well-defined, greyish translucency of the sclera) in 2%. The incidence was found to rise with increasing age. Preplaques are more rarely present in Eskimos than in Copenhagen Caucasians, where the incidence of plaques is the same. The cause of this ethnic difference is discussed.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
