A simple system has been developed for the clinical grading of the presence and severity of lens opacities. The density of nuclear opacities as seen on clinical slit-lamp examination are graded in comparison with a set of standard photographs. The extent of cortical opacities seen on retroillumination is estimated in terms of segments involved. The dimensions of posterior subcapsular opacities are measured using slit beam. It should prove to be of considerable use in clinical and epidemiologic studies of cataract.
