Summary

Self-administered computerized sight-testing is feasible and acceptable in hospital eye clinics. Most patients successfully used the Landolt C test, comparable to traditional Snellen acuity measurements.

Area of Science:

  • Ophthalmology
  • Medical Technology
  • Human Factors Engineering

Background:

  • Traditional visual acuity testing often requires direct supervision.
  • Assessing patient and staff acceptance of new technologies is crucial for implementation.
  • Hospital outpatient eye departments seek efficient and patient-friendly diagnostic tools.

Purpose of the Study:

  • To evaluate the feasibility of self-administered computerized sight-testing.
  • To determine patient and staff acceptability of computerized visual acuity tests.
  • To compare the accuracy of a computerized Landolt C test with traditional Snellen acuity.

Main Methods:

  • A feasibility study involving 86 patients (aged 20-79) in a hospital eye clinic.
  • Comparison of visual acuity measured by Snellen charts and a screen-based Landolt C test.
  • Self-administered computerized test with tape-recorded instructions and minimal intervention.

Main Results:

  • Mean visual acuities from both methods were not significantly different, with similar variances.
  • Over 70% of patients completed the self-administered test independently.
  • The computerized test was preferred by most patients, excluding the oldest age group.

Conclusions:

  • Self-administered computerized sight-testing is a viable and acceptable method in outpatient eye settings.
  • The Landolt C test demonstrates comparable accuracy to Snellen acuity.
  • This technology provides a foundation for large-scale development and implementation.
