Amblyopia screening

摘要

Pre-literate children are screened for amblyopia utilizing a simple device. A pair of eyepieces are mounted by a static structure so that the fields of view through the eyepieces are segregated. A card having two different, spaced pictorial representations of common physical objects or beings is mounted to the static structure so that the pictorial representations are visible through the eyepieces. If the pre- literate child is not able to accurately report both of the different pictorial representations on the card, the child is sent for more detailed testing.
