Summary

Parent-administered electronic visual acuity testing (EVA) is reliable for children. This method significantly reduces the number of optotypes needed by technicians, improving clinic efficiency.

Area of Science:

  • Ophthalmology
  • Pediatric Optometry
  • Clinical Research

Background:

  • Accurate visual acuity measurement is crucial for diagnosing and managing pediatric eye conditions.
  • Traditional visual acuity testing can be time-consuming and requires trained personnel.
  • Developing efficient and reliable screening tools is essential for pediatric eye care.

Purpose of the Study:

  • To assess the accuracy of parent-administered visual acuity testing using the electronic visual acuity tester (EVA).
  • To evaluate the potential of the EVA as a tool to enhance the efficiency of in-office visual acuity testing.

Main Methods:

  • Prospective experimental study involving two parts.
  • Part I: Compared parent-administered EVA results with ophthalmic technician measurements in 64 children.

  • Part II: Compared visual acuity testing efficiency between a parent prescreening group and a full protocol group in 44 children.

    • Main Results:

    • High reliability was found between parent-determined and technician-determined visual acuity scores (r = 0.91 OD, 0.81 OS).
    • Parental prescreening with EVA significantly reduced optotype presentations by technicians (66% fewer for OD, 68% for OS).
    • 93% of right eye and 85% of left eye parent scores were within one line of the technician's score.

    Conclusions:

    • Parent-administered EVA provides reliable visual acuity measurements in children.
    • Parental prescreening using EVA streamlines the testing process, requiring fewer optotype presentations.
    • Implementing parent-assisted EVA screening can lead to greater efficiency in clinical settings.
