Visual field indices are similar between Humphrey Field Analyzer Programs 30-2 and 24-2. Using all double threshold determinations improves short-term fluctuation accuracy for glaucoma patients.

Area of Science:

  • Ophthalmology
  • Optometry
  • Visual Science

Background:

  • Automated threshold static perimetry quantifies visual field sensitivity.
  • Visual field indices summarize sensitivity distribution.
  • Weighting factors can adjust indices for threshold variation.

Purpose of the Study:

  • To assess the impact of weighting factors on visual field indices.
  • To compare indices from Humphrey Programs 30-2 and 24-2.
  • To examine the relationship between double threshold determinations and short-term fluctuation.

Main Methods:

  • Analysis of 60 primary open-angle glaucoma patient visual fields (Humphrey Field Analyzer Program 30-2).
  • Calculation and comparison of unweighted and weighted visual field indices.

  • Assessment of agreement using 95% confidence limits.

    • Main Results:

    • Weighting function minimally affected mean deviation but slightly reduced short-term fluctuation and increased standard deviations.
    • Indices from Programs 30-2 and 24-2 showed minimal differences.
    • Short-term fluctuation increased with more double threshold determinations.

    Conclusions:

    • Weighting factors have limited clinical impact on visual field indices.
    • Humphrey Programs 30-2 and 24-2 yield comparable indices.
    • Utilizing all double threshold determinations enhances the accuracy of short-term fluctuation as an indicator of intra-test variability.
