The expert panel recommends a child-based performance measure for vision care of children aged 36 to <72 months, defined as:
Numerator: Number of children from the denominator who completed a valid* vision screening in a medical or community setting, or received an eye examination by an optometrist or ophthalmologist at least once between the ages of 36 to <72 months.
Denominator: All children who turn 72 months of age by December 31st of the reporting year in the entire population, or a representative sample.
*For all performance measures, “valid vision screening” is defined as: vision screening attempted using a recommended quantitative method (See Vision Screening Recommendations) with an outcome of “pass” OR another outcome (fail or untestable) AND evidence that the child was referred or re-screened. Thus, a non-passing result without evidence of a referral or rescreen is considered an invalid screening and is not counted in the numerator. Acceptable evidence of referral would be the date of the appointment, and name of consulting ophthalmologist or optometrist reported by the screening agency.
