Doppler imaging is a non-invasive, repeatable and reliable method of qualitative and quantitative assessment of blood flow in the ocular vessels. The article explains benefits of using Doppler imaging in everyday ophthalmic practice and its possibilities in the differential diagnosis and monitoring of the patient’s condition by physicians of different specialties. Furthermore, the article lists most common ophthalmological pathologies using cases from author’s own practice, with a discussion of the acquired images. The issues related to the safety of the use of ultrasound in ophthalmology are described in detail, paying special attention to the applicable standards based on the Mechanical Index and Thermal Index, defining the limit exposure of the eyeball to the effects of the ultrasound beam emitted by the ultrasound transducer. The limitations of this method, which should be taken into account when using this modality, are also described.
