[Optical coherence tomography angiography and cardiovascular diseases. An overview of the current knowledge]

BACKGROUND

Cardiovascular diseases (CVD) are the leading cause of death worldwide. The observability of retinal vessel changes in the context of CVD by funduscopy has been known for a long time. Optical coherence tomography angiography (OCTA) is a novel technique for noninvasive detailed imaging and quantification of the retinal microcirculation. The OCTA enables the visualization of vascular changes in a simple and well-reproducible way. Its applications are not limited to the field of ophthalmology. In recent years, several experimental and clinical studies have been published on vascular changes detectable with OCTA in CVD. This review summarizes the most important findings of these studies.

METHODS

This work is based on a comprehensive review of the literature and on the presentation of own data.

RESULTS

Nowadays, OCTA studies are available for many diseases of the cardiovascular spectrum. This indicates that systemic vascular diseases are associated with changes in the retinal microcirculation. These changes can be visualized and reproducibly quantified with OCTA. In many diseases subclinical changes, which are detectable by OCTA, occur before the underlying disease causes otherwise measurable changes or noticeable symptoms for the patient.

CONCLUSION

The OCTA is a promising imaging method in the context of CVD in both scientific and clinical applications. It can be used for the diagnostics and quantification of retinal vascular changes. Further studies will show whether OCTA can be of assistance in the estimation of individual systemic cardiovascular risk profiles.
