Oculokinetic perimetry (OKP) calibration showed a weak correlation with standard visual field testing. Factors like fixation duration and Troxler's effect impact OKP accuracy in glaucoma patients.

Area of Science:

  • Ophthalmology
  • Visual Psychophysics
  • Medical Technology

Background:

  • Oculokinetic perimetry (OKP) is a visual field testing method.
  • Calibration of OKP against conventional perimetry is needed for clinical application.

Purpose of the Study:

  • To calibrate oculokinetic perimetry (OKP) against conventional perimetric threshold values.
  • To investigate factors affecting OKP accuracy, such as fixation and Troxler's effect.

Main Methods:

  • 33 eyes with glaucoma or ocular hypertension were tested using Humphrey Field Analyzer (Central 30-2) and OKP.
  • Frequency of seeing data from OKP was plotted against standard visual field thresholds.
  • Fixation times were manipulated in a subset of subjects to assess Troxler's effect.

Main Results:

  • A weak relationship was found between OKP and standard visual field thresholds.
  • Poor fixation, Troxler's effect, and fixation duration influenced OKP results, leading to false positives and negatives.
  • The average OKP curve indicated a 50% frequency of seeing at a 14.6 dB equivalent threshold, with a 7 dB spread.

Conclusions:

  • OKP requires careful calibration and consideration of fixation stability and adaptation effects.
  • Current OKP methods show limitations in accurately reflecting conventional visual field thresholds in glaucoma and ocular hypertension.
