RESEARCH DATA
BRIGHTNESS SENSE

1.  Hofeldt, TS, Hofeldt, AJ.: BJO 1999
Topic: "Color Rivalry with Brightness Measurement"

  • 24 Amblyopes 0.3 to 1.8 log defects

  • 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

  • 16 Normal subjects, no false positive

  • The depth of Amblyopic defect and lines of acuity disparity were highly correlated. (r=0.85, p<0.0001)

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  Kane SA.: 2016, Unpublished to date.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.
