Area of Science:

  • Ophthalmology
  • Medical Simulation
  • Visual Field Testing

Background:

  • Visual field examination is crucial for diagnosing and monitoring various eye conditions.
  • Simulating these examinations can enhance understanding and training.
  • Existing simulation tools may lack flexibility or comprehensive features.

Purpose of the Study:

  • To introduce Perisim 2000, a software program designed for simulating visual field examinations.
  • To highlight the program's capabilities in testing different examination strategies against diverse visual field data.
  • To emphasize the educational value of Perisim 2000 for clinicians and students.

Main Methods:

  • The Perisim 2000 program allows simulation of interactions between various visual field examination strategies and stored visual fields.

  • It incorporates normal and pathological visual fields, alongside different observer (patient) behavior patterns.
  • Users can select from predefined strategies or define new visual field and observer patterns.

    • Main Results:

    • The program supports a wide range of visual fields, patient behaviors, and examination strategies, including full bracketing, tendency-oriented perimetry (TOP), and Weber's dynamic program.
    • Results can be visualized in multiple formats: numerical tables, symbolic, gray tone, pseudocolor, or profile displays.
    • Statistical programs and cumulative defect curves are integrated for comprehensive analysis.

    Conclusions:

    • Perisim 2000 offers considerable learning and teaching benefits in the field of visual field examination.
    • The software is user-friendly, with ample explanations available, making it accessible for training purposes.
    • It provides a flexible platform for exploring and understanding the nuances of visual field testing and patient responses.
