Optokinetic nystagmus.
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.
