Video Screening for Visual Impairment of Infants

"A domenstic apparatus, scenario, and procedure is applied to record all the behavioral phenotypes.~For each standardized procedure, the guardian sits in the chair, holding the infant facing the mobile phone screen. Each infant is given a few minutes to adapt to the surroundings and to be calm before recording. No hints or simulations are permitted during the entire process. The recording process lasted for about 3 minutes to ensure that behavioral phenotypes could be completely recorded."
