Primary angle-closure glaucoma among Alaskan Eskimos.
An epidemiological study of the occurrence of angle-closure glaucoma was made under the Eskimos population of the Norton Sound and Bering Straits region of Alaska. Among 1673 Alaskan Natives examined 14 cases (0.8%) of angle-closure glaucoma were found, in 0.5% of the men and 1.2% of the women; for persons above the age of 40 years these figures were 2.1% and 5.5% respectively. Angle-closure glaucoma was found in 11.8% of women above the age of 60 years. A shallow anterior chamber was seen twice as frequently in women as in men. Above the age of 30 years the chamber angle was considered to be occludable in 2% of men and 7.5% of women on gonioscopic examination. The average intra-ocular pressure of the right eyes of men was 11.7 mm Hg (s.d. 3.3) and of women 12.0 mm Hg (s.d. 3.4). Primary open-angle glaucoma was not seen in the population being studied.
