To compare optical coherence tomography (OCT) acquisition times between the Heidelberg SPECTRALIS OCT2® module and Zeiss CIRRUS™ HD-OCT Model 6000 in a glaucoma clinic setting.
Approach:
Method: Study Design
Method: Imaging Protocol
Method: Data Collection
Key Findings:
Cirrus 6000 had a total scan time of 115.9 ± 44.7 seconds, significantly faster than Spectralis OCT2 at 157 ± 46.4 seconds (p < 0.001).
RNFL acquisition times were shorter with Cirrus 6000 (50.8 ± 29.7 seconds) compared to Spectralis OCT2 (99.5 ± 32.7 seconds; p < 0.001).
Macular scan times did not show significant differences (p = 0.180).
Cirrus 6000 offers meaningful time savings for RNFL imaging, potentially improving workflow efficiency in high-volume glaucoma clinics, while Spectralis OCT2 demonstrated greater reliability in challenging imaging conditions.
Limitations:
Different scoring scales for image quality precluded direct cross-device comparison.
Study limited to a specific patient population at a single institution.
Conclusion:
Device selection should be individualized based on patient characteristics, clinic workflow, and imaging priorities, as there is no single superior platform.
