Abstract
To evaluate the trend in a series of observations, blurred by random fluctuations, is a problem encountered in follow-up studies of visual fields from glaucoma patients. The imminent risk of falsely estimating, say, the effects of therapy by incautious sampling and insufficient number of observations is described in the present communication.
