Acquired colour defects under restricted viewing time: a new diagnostic technique?
The effect of reduced viewing time on classification of colour vision by means of the City University Colour Vision Test is investigated in sufferers from diabetes and optic neuritis. The results suggest that patients with these conditions give non-normal responses when viewing time is reduced to 3.75 m. It may be possible to use the response obtained to diagnose the presence of ocular disease.
