Describing Extensive Red Artifacts on Zeiss OCT Macular Cube
Describe as "acquisition artifacts" or "signal artifacts" affecting image quality and requiring scan repetition for accurate interpretation.
Understanding Red Artifacts on Zeiss OCT
Red artifacts on Zeiss OCT macular cube scans represent acquisition-related signal problems that compromise image quality. While the provided evidence focuses primarily on OCTA nomenclature 1, the framework for describing artifacts applies to structural OCT as well.
Recommended Terminology
Based on standardized imaging nomenclature principles:
- Primary term: "Acquisition artifacts" - this captures the technical nature of the problem 1
- Alternative: "Signal artifacts" - aligns with standardized OCT terminology conventions 1
- Severity descriptor: "Extensive" or "multiple" when red artifacts are widespread
Clinical Significance
Artifacts in OCT macular scans are extremely common - affecting 84.7% of Cirrus scans overall, with 32.7% having artifacts in the critical center 1-mm area 2. However, clinically significant artifacts that alter thickness measurements by >50 μm or >10% occur in only 5.1% of Cirrus scans 2.
Key Action Point
Scans with extensive red artifacts should be repeated - these represent poor acquisition quality that can affect diagnostic accuracy and thickness measurements 2, 3.
