Area of Science:

  • Ophthalmology
  • Neuroscience
  • Human-Computer Interaction

Background:

  • Conventional visual function assessments are crucial for diagnosing and monitoring ocular conditions.
  • Traditional eye movement assessments can be time-consuming and require specialized equipment.
  • Tablet-based applications offer a potential for accessible and portable visual function testing.

Purpose of the Study:

  • To develop and pilot-test a tablet PC-based application for assessing eye movements.
  • To investigate the functional sensitivity of tablet-based ocular motor metrics to variations in conventional visual function parameters.
  • To explore the feasibility of using tablet-based eye movement assessment for screening and monitoring.

Main Methods:

  • Developed a tablet PC-based application for eye movement assessment.
  • Recruited 23 healthy adults to perform smooth pursuit and saccadic eye movement tests at three difficulty levels.
  • Stratified participants based on conventional visual function test results for exploratory analysis.

Main Results:

  • Significant differences in smooth pursuit traversal time and velocity were observed across difficulty levels (p < 0.05).
  • Saccadic movements showed significant mean accuracy differences between difficulty levels (p < 0.05).
  • Higher horizontal phoria and specific near convergence amplitude points correlated with altered smooth pursuit and saccadic performance (p < 0.05).

Conclusions:

  • Tablet-based ocular motor metrics demonstrated exploratory associations with conventional visual function measures in healthy adults.
  • The developed application shows potential as a feasible, low-cost tool for exploratory screening and functional monitoring of eye movements.
  • Further validation is required to establish its role as a diagnostic tool.
