Abstract

In case of various kinds of diseases of the fundus of the eye, clinicians usually use the study in the opposite view for diagnostics purposes, thus obtaining and examining a real image of the fundus. Therefore, it is quite natural to desire first of all to be able to photograph a real reverse image of the retina. This is precisely the goal we set ourselves when we were studying the blood filling of retinal and choroidal vessels under the influence of various drugs or electrical irritation of the vagus and sympathetic nerve in higher animals.
