This screening battery consists of a threshold visual field perimetry and six test items. Information about each item is found on the instructions page, including information on the stimulus (or stimuli), administration instructions, and what constitutes a pass or fail for each item.

While the battery itself has not been validated, the CPC-Q item has been validated for screening for posterior cortical visual dysfunction (see the instruction page for references). The other five items were arrived at through expert consensus by the PCA Assessment Working Party. It is recommended that visual field perimetry and at least two additional items from the VisCorD are performed for screening.
