The age variation of "senile' cataract in various parts of the world.

As its name implies, senile cataract is age-related. A survey of 9 studies indicates to what extent the epidemiology of senile cataract can be represented by Gompertz plots. These are shown to be suitable separately for men and women and to enable one to distinguish between inborn and environmental influences. Further support is obtained for the view that myopia and cataract may be linked, and attention is drawn to the potentially noxious effect of (ultraviolet) light.
