The OSCAR-MP QC Criteria for Retinal OCTA Scans

| O | Obvious problems not covered by the items below Focus, defocus, beam placement, illumination, opacities, shadowing | 
| S | Signal strength Consider device-specific thresholds for signal strength  | 
| C | Centration Evaluate correct placement of the scanning area depending on the region of interest  | 
| A | Algorithm failure Evaluate accurate segmentation of the different vessel plexus  | 
| R | Retinal pathology Check the presence of any retinal pathology and evaluate whether it impairs the analysis of the retinal vasculature  | 
| M | Motion artifacts Evaluate different types of motion artifacts and estimate the affected proportion of the image  | 
| P | Projection artifacts Search for projection artifacts of superficial vessels into deeper layers  |
