Prevalence of Exfoliation Syndrome in Finland

Three separate investigations are reported, covering a total of 795 patients from different parts of Finland, two of them consisting of inmates of old people's homes in two towns (N = 205 and 262) and one a randomly selected population from a rural commune (N = 328). They show the mean prevalence of exfoliation syndrome (PS) to be 14.2% in age group 60 less than or equal to 69 years, 21.9% in age group 70-79 and 34.7% in age group greater than or equal to 80. The prevalence increases statistically significantly with age. The mean prevalence of PS in all three groups was 22.4%. No isolate-like accumulation of PS could be demonstrated. The figures seem representative of the hole country.
