Ocular Color Doppler ultrasound (OCDUS) has been underutilized in the past as a diagnostic technique, although several OCDUS-based studies were performed in the last 30 years for diagnosis or monitoring of some ophthalmological, cerebrovascular or systemic diseases. 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 literature.
Venturini et al. (Mon,) studied this question.
