This study used optical coherence tomography (OCT) data to identify key indicators for distinguishing normal eyes from those with glaucoma. The findings suggest that specific rules derived from OCT scans can improve glaucoma detection accuracy.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Data Mining

Background:

  • Glaucoma is a leading cause of irreversible blindness worldwide.
  • Early detection and accurate diagnosis are crucial for managing glaucoma and preventing vision loss.
  • Optical coherence tomography (OCT) provides quantitative structural data relevant to glaucoma assessment.

Purpose of the Study:

  • To develop and validate association rules for differentiating between normal and glaucomatous eyes.
  • To utilize quantitative summary data from StratusOCT scans in a Taiwan Chinese population.
  • To apply data mining techniques for glaucoma detection based on OCT measurements.

Main Methods:

  • Retrospective analysis of StratusOCT data from 64 glaucoma patients and 71 normal subjects.

  • Extraction of glaucoma variables including retinal nerve fiber layer thickness and optic nerve head parameters.
  • Application of a self-organizing map and decision tree algorithm to identify features and derive association rules.

    • Main Results:

    • Significant differences in visual field mean deviation between normal (-0.55 +/- 0.57 dB) and glaucoma (-4.30 +/- 3.32 dB) groups.
    • Decision tree analysis identified vertical cup-to-disc ratio and inferior quadrant thickness as key features.
    • Three specific association rules were established for glaucoma detection.

    Conclusions:

    • The developed association rules, derived using a decision tree, show promise for enhancing glaucoma detection.
    • This quantitative approach using OCT data offers a novel method for identifying glaucomatous changes.
    • The findings may contribute to earlier and more accurate diagnosis of glaucoma in clinical practice.
