A method is described of modifying the Bausch & Lomb Autoplot to obtain background and test target luminances of 10.02 cd/m2 and 32.8 cd/m2, respectively. Together with the use of a 2-mm target, these test conditions closely correspond to those of the Goldmann perimeter. These conditions can be maintained to provide more standardized perimetry than is currently available with the Autoplot.
Luminance measurements of targets and backgrounds revealed differences for various types of perimetric instruments. A lack of uniform testing conditions for instruments of the same design was also noted. Of the instruments measured, hemispheric-projection perimeters seemed to provide the most repeatable test conditions.
