A simplified stimulus value notation using preferred stimulus combinations for Goldmann quantitative perimetry

In an effort to return to the simplicity intended by Goldmann, the authors propose adoption of a two-digit stimulus value (SV) nomenclature for defining targen area luminance and contrast on a properly standardized Goldmann-type perimeter. The system is designed to aid the examiner in target selection, mental interpolation and isopter construction, and to facilitate computer manipulation.
