Visual Contrast Detection Cannot Be Predicted From Surrogate Measures of Retinal Ganglion Cell Number and Sampling Density in Healthy Young Adults [Visual Psychophysics and Physiological Optics]

Conclusions.
Despite considerable variation in both psychometric functions for contrast detection and surrogate measures of retinal ganglion cell number and sampling density among healthy eyes, relationships between these measures are weak. These relationships are unlikely to be exploitable for improving clinical tests in healthy populations.
