Oxygenation and Retrolental Fibroplasia

Abstract

The causative factors of disease may be broadly grouped under three headings: those due to injurious agents, those resident in the susceptible host and those deriving from the environment in which host and agent find themselves¹; clarification of causation is to be sought along "a broadened front on which the laboratory and the clinic or the field have been brought together for interpretation of a problem."² These principles guide the search for causes of a noncommunicable illness like retrolental fibroplasia (RLF) no less than that for viruses of infantile paralysis, for example; investigation proceeds in the clinic, field and . . .
