SPHEROID DEGENERATION OF CORNEA AND CONJUNCTIVA
The incidence of spheroid degeneration has been studied in a series of 659 Eskimos from Arctic South‐West Greenland and one of 810 Caucasians in Copenhagen with its temperate climate. The over‐all prevalence was highest among the Eskimos (12.3 per cent against 4.1 per cent among the Copenhageners, P...

| Summary: | The incidence of spheroid degeneration has been studied in a series of 659 Eskimos from Arctic South‐West Greenland and one of 810 Caucasians in Copenhagen with its temperate climate. The over‐all prevalence was highest among the Eskimos (12.3 per cent against 4.1 per cent among the Copenhageners, P < 0.001). The prevalence was found to be independent of sex, but to rise with increasing age (however, with a fall again after the age of 70 years in Copenhagen). The spheroid deposits were present on the conjunctiva in 74 per cent, on the cornea in 18 per cent, and at both sites in 8 per cent. 71 per cent of the subjects displayed autofluorescent globular deposits. These constituted 10 per cent of the total number of globules. The number of globules per subject averaged 30. Spheroid degeneration was rarely found temporally in Eskimos. Spheroid degenerative processes are most frequently seen in Pingueculae, but are not considered bear any relation to pterygium. |
