Hypothesis
Can the integration of Standard Automated Perimetry (SAP) and Optical Coherence Tomography (OCT) data improve the accuracy of glaucoma diagnosis using Artificial Neural Networks (ANNs)?
Conclusion
Integrating parameters from both SAP and OCT significantly enhances the performance of ANNs in diagnosing glaucoma.
Supporting Evidence
- The diagnostic accuracy from a combination of fused SAP and OCT data was 95.39%.
- Fused OCT and combined fused OCT and SAP data provided similar AROC values of 0.978.
- ANNs based on the OCT parameters did not perform significantly worse than those based on fused data.
Takeaway
This study shows that combining two types of eye tests can help doctors better identify glaucoma, a disease that affects vision.
Methodology
Data from 125 healthy individuals and 135 glaucoma patients were analyzed using ANNs with both fused and non-fused parameters from SAP and OCT.
Potential Biases
Potential bias from selection criteria and the reference standard used for diagnosing glaucoma.
Limitations
The study's reference standard for glaucoma diagnosis was based on optic nerve head morphology, which may not correlate perfectly with functional tests.
