Stratus OCT image analysis with spectral-domain OCT (Topcon 3D OCT Viewer)

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomedical Engineering

Background:

• Optical coherence tomography (OCT) is crucial for retinal imaging.
• Accurate analysis of OCT data is vital for diagnosing and monitoring eye diseases.
• Comparing different OCT analysis software is important for clinical practice.

Purpose of the Study:

• To evaluate the accuracy of the Topcon 3D OCT Viewer for analyzing Stratus OCT data.
• To compare the segmentation error rates and retinal thickness measurements between Topcon 3D OCT Viewer and Stratus OCT.

Main Methods:

• Retrospective analysis of 356 eyes' Stratus OCT fast macular thickness map data.
• Comparison of segmentation error (SE) rates and scores between Topcon 3D OCT Viewer and Stratus OCT.
• Measurement of retinal thickness differences in SE (-) and SE (+) groups.

Main Results:

• Topcon 3D OCT Viewer demonstrated significantly lower SE rates (30.9% vs 38.2%) and mean SE scores (0.33 vs 0.48) compared to Stratus OCT (p<0.011).
• In the SE (-) group, mean differences in the central 1 mm zone were -2.79 μm (p<0.001).
• Automated center point thickness showed a mean difference of 1.49 μm (p=0.152).

Conclusions:

• Topcon 3D OCT Viewer provides accurate analysis of Stratus OCT data with superior segmentation performance.
• The software can be used interchangeably for macular thickness measurements.
• Careful clinical interpretation is necessary when using the Topcon 3D OCT Viewer.
