Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Meibomian gland dysfunction (MGD) diagnosis relies on quantifying meibomian gland morphology from meibography images.
  • Existing methods lack automated quantification of individual meibomian gland morphological features.

Purpose of the Study:

  • Introduce an automated artificial intelligence (AI) approach for segmenting meibomian glands in infrared meibography images.
  • Analyze morphological features of individual glands to aid in MGD diagnosis and management.

Main Methods:

  • Utilized a dataset of 1443 meibography images, divided into development and evaluation sets.
  • Trained deep learning models for gland segmentation and ghost gland identification.
  • Analyzed gland features including local contrast, length, width, and tortuosity.

Main Results:

  • Achieved 63% mean intersection over union for gland segmentation and 84.4% sensitivity/71.7% specificity for ghost gland identification.
  • Identified low gland local contrast as a primary indicator for ghost glands.
  • Successfully analyzed associations between morphological features and ghost glands using a support vector machine.

Conclusions:

  • The developed AI approach automates meibomian gland segmentation and ghost gland identification from meibography images.
  • Enables quantitative analysis of individual meibomian gland morphology.
  • Offers a novel tool for the diagnosis and management of MGD.
