· Amblyopic defect related to vision loss, p<0.0001
2. Gise, R Kane SA.: ARVO Paper #3819, 2016
Topic: "iPad Rivalrous Program in Amblyopia"
· 16 Amblyopes, all detected

3. Kane SA.: 2016, Unpublished to date.
Topic: "iPad Screening Program for Amblyopia"
· 211 students studied, Ages 3 to 14 years of age
· Summary
Of the 210 children tested, there are 208 true negative, 2 true positives, zero false negative, and zero false positive. The true positives are (1) an 8 year old undergoing treatment for amblyopia with current acuities of 20/20 OD and 20/25 OS and (2) one amblyope was detected, a 10 year old having 20/20 OD and 20/40 OS. Of the true negatives, one child is a successfully treated amblyope having 20/20 vision in each eye; repeated inter-ocular brightness test results are 0.3 OD defect, 0.3 OS defect, and zero defect. The sensitivity is 100% for detecting amblyopia in the 210 children. A 4-year-old child who did not understand brightness could not tested.
