Optokinetic nystagmus (OKN), one of the phenomena examined in order to analyse balance and sight disturbances, is manifest in two types: The cortical and the subcortical OKN. Their main distinction is in the velocities. They are also transmitted via different nervous pathways. This paper introduces a method to record the OKN of the two eyes individually. While joint OKN‐recordings of both eyes together may mask disturbances of one eye, the separate recordings could reveal them. The discussion deals with applications of OKN‐examination to ergophthalmology e.g. in cases of industrial solvent intoxications.
