    1547 of 1840 (84%) eligible people were examined.

    The population prevalence of bilateral visual impairment (visual acuity<6/12) was 30%, of which 72% was potentially remediable. 92 of these 448 cases (21%) had visual acuity<6/60 ( « blindness ») in one or both eyes.

    Prevalence of cataract causing visual impairment was 30% ; 88% of these people were not in touch with the eye services.
