Summary
This summary is machine-generated.

Glaucoma patients find visual field testing (VFT) challenging, but their self-perceived performance doesn't align with VFT reliability. Psychomotor vigilance test results showed a weak link to VFT reliability.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Psychology

Background:

  • Visual field testing (VFT) is crucial for glaucoma detection and monitoring.
  • VFT is a subjective test, requiring patient vigilance for reliable results.
  • Patient attitudes and VFT reliability are key factors in test accuracy.

Purpose of the Study:

  • To understand patient experiences and preferences regarding VFT.
  • To assess the relationship between VFT reliability indices and psychomotor vigilance.

Main Methods:

  • A cross-sectional study involving 140 glaucoma patients.
  • Collected VFT reliability indices and survey data on patient experience.
  • Administered the Walter Reed Psychomotor Vigilance Test (PVT) to 46 patients to measure reaction times.

Main Results:

  • Most patients found VFT difficult, regardless of self-rated performance.
  • Higher average reaction times correlated with older age and lower education levels.
  • A marginal correlation was found between average reaction time and VFT reliability status.

Conclusions:

  • Patient self-assessment of VFT performance does not correlate with current reliability indicators.
  • Slower reaction times showed a limited impact on VFT reliability.
  • Further research is needed to explore the influence of psychomotor reaction time on other VFT outcomes.
