EyeArt UK NHS 20K Patients Study

Tufail et.al conducted an independent, observational study of 20,258 consecutive patient visits comparing three automated DR screening systems: EyeArt, Retmarker DR, and iGrading.

  • Compared to quality assured manual grading, EyeArt v1.0 achieves
    • Acceptable sensitivity for referable DR
    • Sufficient specificity to make it a cost effective alternative
  • Sensitivity and false positive rates for EyeArt were not affected by ethnicity, gender, or camera type
