What is the optimum test battery for visual screening of older people and what sensitivity and specificity does this have for detecting correctable visual impairment? The study is mainly quantitative. A battery of computerised visual screening tests will be compared with a full eye examination, in two blind studies. The first study will be used to refine the test battery and to develop a flip chart rapid vision screener. The sensitivity and specificity of the refined computerised screener and flip chart rapid screener will be evaluated in a second study. The main target conditions are uncorrected refractive error and cataract, since these are readily correctable. The sensitivity and specificity of the screening tools for detecting these problems will be calculated. The value of different screening venues will also be investigated.
