    How to Report the Measure

    Numerator: Patients with improvement of mean deviation or stability of mean deviation within 6 months of initiating therapy.

    • Performance met (patient included in numerator and denominator):
      • Patients whose mean deviation was stable (+ 1dB), 6 months after intiating therapy. 
      • Patients with improvement of mean deviation within 6 months after initiating therapy.
    • Performance not met (patient not included in numerator, but included in denominator): Patients whose mean deviation worsened by (> 1dB) within 6 months after  intiating therapy.
