In the framework of the targeted project FATMA (Prevention and control of risk factors) of the italian national research council, longitudinal epidemiological study on prevalence and incidence of visual impairment in Privernò, Italy was carried out. A random sample of 860 people aged 45-69 years participating in a population based study on cardiovascular risk factors in Priverno, were submitted to a standardized ophthaimological examination. The definition of blindness and low vision suggested by WHO were adopted. 618 subjects or 80% of the survivors of the Priverno sample aged 45-69 years at the baseline were re-examined seven years after the base-line. Prevalence of blindness and low vision passed respectively from 0.16 and 0.49% to 0.32 and 1.62%; an incidence of 0.16% of blindness and 1.13% low vision was observed. Finally, the causes of visual impairment found at base-line are compared with those found among the new cases of visual impairment at follow-up.
