OCDUS can provide quantitative and reproducible measurements of the blood flow of the main orbital vessels at the retrobulbar level. In this narrative review we aimed to investigate the relevance of OCDUS as an imaging modality in several ophthalmological, cerebrovascular and systemic diseases based on the current
