[Evaluation of the effects of pneumogenic hypoxemia on the nervous tissue by the determination of the critical flicker fusion frequency of the central retina].
Considering the eye an extroflection of the brain it is possible to detect a decrease of nervous tissues efficiency during hypoxia through a deficit of eye function. The authors studied a highly specialized retinal function that is extremely sensitive to low values of PaO2: the so called "critical flicker fusion frequency". The authors tested 14 patients with respiratory disorders and PaO2 levels between 36.5 and 67.1 mmHg. All patients showed impairment of this function.
