Artificial neural networks (ANN) accurately distinguished healthy eyes from diseased eyes using pattern electroretinography (PERG) signals. This AI approach achieved 92% correct classification, aiding physicians in diagnosis.

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Artificial Intelligence

Background:

  • Pattern electroretinography (PERG) measures retinal cell responses to visual stimuli.
  • Distinguishing between healthy and diseased eyes is crucial for timely treatment.
  • Artificial neural networks (ANN) offer potential for analyzing complex biological signals.

Purpose of the Study:

  • To develop and evaluate an ANN model for classifying PERG signals.
  • To differentiate between healthy and diseased eyes based on PERG data.
  • To assess the diagnostic accuracy of the ANN model.

Main Methods:

  • Analysis of PERG signals from 172 healthy and 148 diseased subjects.
  • Utilizing a supervised competitive learning vector quantization network (a type of ANN).

Related Experiment Videos

  • Training the ANN to classify eyes as healthy or diseased.

    • Main Results:

    • The ANN model achieved 94% sensitivity and 90.32% specificity.
    • Overall correct classification rate was calculated to be 92%.
    • False negative rate was 5.94% and false positive rate was 9.67%.

    Conclusions:

    • The ANN model effectively distinguishes between healthy and diseased eyes using PERG signals.
    • The model's performance aligns with physician diagnoses.
    • This AI-driven approach can assist clinicians in making definitive diagnoses.
