Background: To compare life span of persons with and without ocular pseudoexfoliation syndrome (PES). Methods: The study is based on an epidemiological survey conducted in Sor-Trondelag county, Norway, in 1985-86. All inhabitants over 64years of age (2109 individuals) were invited. Mortality information was obtained from The Norwegian Institute of Public Health in 2014, by which time 99% of the participants were deceased. Results: When adjusting for age and gender, life span was not statistically different in persons with and without PES. Following the diagnosis of PES, patients' survival was up to, and beyond, 30years. Conclusions: Our observations suggest that, despite all the systemic aberrations reported in persons with ocular PES, none or only marginal functional changes are caused in extraocular organs and tissues. The present study supports the notion that systemic PES is not a life-threatening condition.
