Contrast sensitivity assessment using the visual performance tester.
Abstract
The visual performance tester (VPT), a device that uses patient response time as a variable to assess visual power, is described. Results in 126 emmetropic eyes that had not had surgery are presented. The VPT provides more complete and accurate information about visual performance than the standard visual acuity examination because the device considers all variables involved in visual function results.
