We present a new display mode of the results of an Octopus visual field examination, which allows for an easy and reliable assessment of the local and diffuse components of the disturbances of a visual field. Essentially, this display consists of the cumulative distribution of the local defect values. Application to typical cases is discussed.

The Lens Opacity Meter 701 measures the lens density quantifying the back light scatter of the lens. The instrument emits a modulated dark-red beam which runs along the optic axis of the lens. The stray light is converted into an electrical impulse which is displayed and printed using a numerical scale. The lens density in a normal population was investigated with this instrument in order to study the influence of age on the opacification process.
