title: Preferential looking: parameters and preliminary data of a new computerized version.
abstract: A computerized version of preferential looking (CPL) was developed by the authors. Formal parameters (spatial frequency, luminance, contrast of the stimuli; randomized procedure; computerized statistical control) and preliminary binocular acuity results in 69 healthy children (6-36 months) are compared to those of OPL, FPL and ACP version. Low cost, standardized procedure, statistical control of visual acuity estimates and the need of one operator only are among CPL advantages.
