Summary

Frequency Doubling Technology (FDT) visual field testing is feasible in children aged 5-10 years. Test reliability was similar between younger and older children, suggesting pre-selection is beneficial for accurate results.

Area of Science:

  • Ophthalmology
  • Pediatric Optometry
  • Visual Field Testing

Background:

  • Visual field testing is crucial for diagnosing and monitoring various ocular conditions.
  • Frequency Doubling Technology (FDT) offers a unique method for visual field assessment.
  • Evaluating FDT feasibility in pediatric populations is essential for expanding diagnostic capabilities.

Purpose of the Study:

  • To determine the feasibility of conducting visual field tests using Frequency Doubling Technology (FDT) in children aged 5 to 10 years.
  • To compare test performance and reliability between pediatric groups and adults.

Main Methods:

  • A cohort of 40 healthy children (aged 5-7 and 8-10) and 15 healthy adults underwent FDT visual field testing (C20 threshold test).
  • Subjects had no prior visual field testing experience.

  • Test explanation time, performance time, and fixation losses were recorded for each group.

    • Main Results:

    • Children required significantly longer explanation and performance times compared to adults (P < 0.001).
    • Forty percent of children needed two demonstrations, unlike adults.
    • Children exhibited higher fixation losses (10% right eye, 37% left eye) compared to adults (0%).

    Conclusions:

    • Visual field testing with FDT is feasible in children aged 5 to 10 years.
    • Test reliability was comparable between children aged 5-7 and 8-10.
    • Pre-selection of pediatric participants is recommended to ensure reliable FDT visual field test outcomes.
