Reliability in perimetric multichannel contrast sensitivity measurements

In this study, the reliability of perimetric contrast sensitivity measurements favouring the achromatic, the red‐green and the blue‐yellow post‐receptorial mechanisms was analysed.The ATD multichannel perimeter was built thanks to the support of the Spanish Ministerio de Ciencia y Tecnologia Grants DPI2000-0116-P4-02 and PTR 1995-0909-OP, in collaboration with INDUSTRIAS DE OPTICA SA (San Cugat del Valles, Spain).

Contrast sensitivity perimetry tests along the cardinal directions in color space: correlation with the properties of the neural mechanisms mediating detection of spatio-temporal patterns

It is well-known the advantages of measuring chromatic and achromatic contrast sensitivity for detecting pathologies. But these measurements are rarely used in clinical practice, due the complexity of the measurements and the examinator specialization. In fact, there is not a complete characterization of the response of the visual pathways to achromatic and chromatic spatio-temporal frequency stimuli. We have designed a new experimental device that facilitates these measurements and allow us to characterize the visual response in healthy patients. In this paper, we evaluated the responses of the visual pathways in healthy patients.
