This study introduces a computer-based glaucoma screening system. It combines optic nerve analysis, visual field testing, and expert rules for accurate early detection of glaucoma.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Artificial Intelligence in Healthcare

Background:

  • Glaucoma is a leading cause of irreversible blindness globally.
  • Early detection through screening is crucial for managing glaucoma and preventing vision loss.
  • Current screening methods can be costly and may lack comprehensive diagnostic capabilities.

Purpose of the Study:

  • To develop and evaluate a cost-effective, computer-based glaucoma screening system.
  • To enhance the sensitivity and specificity of glaucoma detection by integrating multiple diagnostic approaches.
  • To provide a tool suitable for large-scale screening programs.

Main Methods:

  • Utilizing fundus image processing techniques, including a novel histogram model for specific retinal nerve fiber layer defects.
