The 2 target option is intended for young infants and babies as a forced choice preferential looking test. Discerning re-fixation eye movements is easier with fewer targets in the presence of strabismus or nystagmus As the child’s confidence grows, touchscreen interaction is encouraged |
The 4 target option is also an ideal preferential looking test, and can also be used as a touchscreen game when the child is old enough to co-ordinate a screen tap
|
For children with good co-ordination, the 9 target option allows the child to perform the test as a touchscreen game This option is not designed for preferential looking |
