Evaluation of the Variability of Ambient Interactive Zippy… : Journal of Glaucoma
o-moderate-stage patients. Objective: To explore the 95% prediction interval of the MD value using the AIZE Rapid test strategy for glaucoma observation. Patients and Methods: This study included 72 patients with stable or suspected glaucoma who underwent the imo AIZE Rapid test 3 times or more within 2 years. Both eyes from each patient were classified as better or worse eyes. They were divided based on baseline MD values into the following 4 groups: MD > −3 dB, −6 dB < MD ≤ −3 dB, −12 dB < MD ≤ −6 dB, and MD ≤ −12 dB. The variability of MD during the observation period and the 95% prediction intervals were analyzed. Pointwise variability of limits at each test location was also calculated. Results: The numbers of better and worse eyes included in the study were 46 and 33. The median follow-up period was 1.3 years (range: 0.5 to 1.9 y). The 95% prediction intervals for MD values were ±1.41 dB for better eyes (n = 46) and ±1.47 dB for worse eyes (n = 33). The 95% prediction intervals i
