Preferential looking: parameters and preliminary data of a new computerized version.

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.

Preferential looking techniques yield important information in strabismic amblyopia follow-up.

Two groups of monocular strabismic patients were followed-up by means of both PL and orthoptic examinations. The first group underwent a full-day occlusion except 1 to 4 hours; the second was occluded less than 4 hours per day. The first treatment regimen proved to be faster in getting pseudo-isoacuity and alternating fixation, but was followed by relative occlusion amblyopia and/or shifting of the dominant eye in three patients. PL techniques proved to be particularly useful in strictly monitoring these patients.
