Performance of a new, 3D-monitor based random-dot stereotest for children under 4 years of age.

Background: The aim of this study was to determine the performance of a new, 3D-monitor based, objective stereotest in children under the age of four.

Methods: Random-dot circles (diameter 10 cm, crossed, disparity of 0.34 degrees) randomly changing their position were presented on an 3D-monitor while eye movements were monitored by infrared photo-oculography.
