Blue cone function in a family with an inherited tritan defect, tested with electroretinography and psychophysics.

Abstract

The sensitivity of the blue cone system to low frequency flicker was tested with a psychophysical and an electroretinographical method. With the psychophysical method the subjects, members of a family with an inherited tritan defect, showed no sign of the presence of the blue cone system. With the electroretinogram the sensitivity was also significantly… (More)
