The expression of electrophysiological Visual Acuity as an equivalent subjective score in a population requires a regression model. Where data are not normally distributed, and/or heteroscedastic, then a linear regression is not appropriate, and so an alternative method is presented-the Passing and Bablok (PB) regression. The choice of units, and conversion between them is also discussed given PBs need for common units, and the likelihood of a normal distribution given this choice of units is considered.
