Accurate Detection

Spot accurately detects the potential indication of these common vision problems:

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Astigmatism (blurred vision)
  • Anisometropia (unequal refractive power)
  • Strabismus (eye misalignment)
  • Anisocoria (unequal pupil size)
  • *Accuracy refers to the sensitivity and specificity of the screening referral recommendation.
