Area of Science:

  • Ophthalmology
  • Medical Technology
  • Glaucoma Research

Background:

  • Glaucoma management requires regular visual field (VF) testing for disease progression monitoring.
  • Existing VF tests can be time-consuming, potentially impacting patient compliance and clinic efficiency.
  • The Ambient Interactive ZEST EX (AIZE-EX) algorithm was developed to optimize follow-up VF assessments.

Purpose of the Study:

  • To compare the diagnostic performance and efficiency of the AIZE-EX algorithm against the standard AIZE test in glaucoma patients.
  • To evaluate if AIZE-EX provides comparable results to AIZE while reducing test duration.

Main Methods:

  • A comparative study involving 92 eyes from 46 glaucoma patients.
  • Patients underwent both AIZE and AIZE-EX tests at follow-up, with baseline AIZE data for comparison.
  • Two standard VF test patterns (24-2 and 24plus(1-2)) were utilized.
  • Key metrics including Mean Deviation (MD), Pattern Standard Deviation (PSD), Mean Sensitivity (MS), and test duration were analyzed.

Main Results:

  • AIZE-EX demonstrated no significant differences in MD, PSD, or MS compared to baseline and follow-up AIZE tests.
  • AIZE-EX significantly reduced test duration by approximately 10-30% (p<0.001) compared to AIZE.
  • Pointwise sensitivity differences confirmed comparable detection of glaucomatous VF abnormalities.

Conclusions:

  • AIZE-EX is a valid and efficient alternative for follow-up visual field testing in glaucoma patients.
  • The algorithm maintains diagnostic accuracy while offering substantial time savings.
  • AIZE-EX may become a preferred choice for routine glaucoma follow-up assessments.
