. During 1977 and 1978 visual screening was performed in 1511 persons born 1907–1921 and taking part in a population survey. 8.4 years later the visual field screening was repeated in 2039 eyes of 1038 persons. The rates of unsuccessful tests improved or remained unchanged. The incidence of non‐glaucomatous visual field defects was 0.006/year. Thus repeated visual field screening of persons in their seventies was both feasible and fruitful.
