V_{max} = maximum amplitude of the b-wave for assumed infinite flash intensities; K = light intensity where b-wave amplitude reaches half saturation; n = a dimensionless constant related to the slope of the intensity response function.
Of parameters V_{max}, n, and K of the two models of the Naka-Rushton equation used in this study (model 1: fit of the function to all data points, model 2: fit of the function to all data points below –1.25 log units (0.53 cd s/m^{2}), only the interocular differences in V_{max2} of the second model correlated significantly with the interocular differences in mean deviation.
