Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Anterior segment optical coherence tomography (AS-OCT) is crucial for diagnosing eye diseases by imaging anterior segment structures.
  • Identifying age-related structural changes is vital for differentiating normal aging from pathological damage in AS-OCT scans.

Purpose of the Study:

  • To predict demographic characteristics, including age, from AS-OCT images using deep learning.
  • To assess the contribution of specific anterior segment regions to demographic prediction accuracy.
  • To differentiate normal age-related structural variations from pathological changes.

Main Methods:

  • A retrospective cross-sectional study involving over 2,000 patients' AS-OCT images (2008-2020).
  • Development of a Vision Transformer (ViT) model for demographic prediction from AS-OCT images.
  • Utilizing Gradient-weighted Class Activation Mapping (Grad-CAM) for visualizing image regions critical to predictions.

Main Results:

  • The study protocol outlines the methodology for predicting demographics from AS-OCT images.
  • The Vision Transformer model is trained and validated on a large dataset.
  • Grad-CAM will identify image areas influencing demographic predictions.

Conclusions:

  • The study protocol provides a framework for predicting demographic characteristics from AS-OCT imaging.
  • Results will enhance clinical understanding of age-related structural changes and demographic influences on ocular structures.
  • This research supports improved diagnosis and monitoring of eye conditions through AI-driven image analysis.
