This technology is based on a reflexive pattern of eye movemnets called OKN, which can be uses to assess visual function.When the eyes detect a continously moving pattern, they will first track a feature of the pattern and then move rapidly in the opposite direction before reinstating the tracking movement. The charateristic movement profile will only occur, if the stimulus is seen by the subject. Therefore the presence or adsence of OKN indictaes the visibility of the visual stimulus. There is no objective method for quantifying OKN that is currently routinely in clinical or community settings.
