Hudson-Stähli's iron-line of cornea in Eskimos.

The Incidence of Hudson-Stähli's iron-line of the cornea (HS) has been studied in 1988 in a series of 265 Eskimos in the Angmagssalik district, East Greenland, and compared with that among 287 Caucasians in Copenhagen, Denmark. The author employed the same method of investigation for both series. HS is absent in young Eskimos less than 19 years), but present in 8 to 20 per cent in the remaining age groups. Eskimos and Caucasians are alike with regard to incidence, binocularity, grade, colour, and site. This goes to show that HS is of endogenous origin, bearing no relation to the frequent occurrence of haemolacria, pterygium, and astigmatism among Eskimos.
