    Reporting Option: 

    • IRIS Registry QCDR for EHR: groups and individuals

    Measure Type: Outcome

    NQS Domain: Effective Clinical Care

    Meaningful Measure Area: Management of Chronic Conditions

    Description:  Percentage of newly diagnosed amblyopic patients with one or more of the following:

    1. A corrected interocular (or if not reported, the uncorrected) visual acuity difference < 0.23 logMAR 3-12 months after first diagnosis of amblyopia
    2. An improvement in the corrected visual acuity of the amblyopic eye of 3 or more Snellen lines (> or = 0.30 logMAR) 3-12 months after first diagnosis of amblyopia 
    3. A final visual acuity in the amblyopic eye equal to 20/30 or better (less than or equal to 0.18 logMAR) 3-12 months after first diagnosis of amblyopia 

    Risk Adjusted: No 
    Performance Rate: 1
    High Priority Measure: Yes 
    Inverse Measure: No 
    Proportional Measure

    To Which Patients Does the Measure Apply?

    Denominator: All patients aged between 3 to 7 years at diagnosis of amblyopia with recognized visual acuity difference of greater than 0.29 logMAR between right and left eye (IOD criterion is to exclude bilateral ametropic amblyopia).

    There are two criteria for inclusion of a patient into the denominator.

    1. Patient characteristics: Description located in “Denominator” (see above).
    2. Diagnosis codes (ICD-10-CM): Codes located in “Diagnosis Codes.”

    The quality measure also has exclusions for the denominator.

    Diagnosis Codes

    • Amblyopia (ICD-10: H53.001, H53.002, H53.003, H53.021, H53.022, H53.023, H53.031, H53.032, H53.033)

    How to Report the Measure

    Numerator: Patients with interocular visual acuity difference of < 0.23 logMAR* or an improvement of three or more Snellen lines (> or = 0.30 logMAR)** in the amblyopic eye or a final visual acuity in the amblyopic eye of 20/30 or better (< or = 0.18 logMAR)*** recorded between 3 and 12 months after first use of amblyopia diagnosis code

    *Difference in visual acuity values between right and left eye (inter-eye)

    **Difference between baseline and visual acuity at 3-12 months in the amblyopic eye (intra-eye)

    ***Absolute visual acuity, not a difference

    Denominator Exclusions: Patients with diagnosis of deprivation amblyopia (ICD 10: H53.01), cataract (ICD –10: H26.01-.06), aphakia (ICD-10: H27.00, H27.01, H27.02, H27.03), or pseudophakia (ICD-10: Z96.1)
