LALES = Los Angeles Latino Eye Study, BDES = Beaver Dam Eye Study, BMES = Blue Mountains Eye Study.

N= number at risk for incidence of visual impairment at baseline; % (CI)=prevalence and 95% confidence interval;

^§The annualized incidence rates are derived from 4-year incidence data for LALES and 5-year incidence data for BDES and BMES.

^*Criterion for Any visual impairment (BDES criterion): Persons with Baseline BCVA better than 20/40 in one or both eyes at baseline and follow-up BCVA 20/40 or worse in the better-seeing eye (including 20/40). Persons with incident blindness are included in the criterion for any visual impairment.

^†Criterion for Blindness (Severe visual impairment) (BDES criterion): Persons with a BCVA better than 20/200 in one or both eyes at baseline and follow-up BCVA 20/200 or worse in the better-seeing eye (including 20/200).

^‡No incident cases.
