Chromatic perception test: a computer based approach

The analysis of luminance visual defects (i.e., obtained with white stimuli on a black background) in the central area of 20°-30° around the fovea provides a valuable tool in neuro-ophthalmological diagnosis. Concerning chromaticity tests, it is well known that they improve the diagnosis of many neurological diseases, such as Multiple Sclerosis, Optic Neuritis, diseases due to vitamin deficiency.. A new automatic technique for testing both B/W and colour campimetry on a computerized apparatus has been set-up and tested on the population of patients of the V Clinica Neurologica of the Umberto I° Hospital of Rome
