“…With age, the vascular wall is remodelled, and the medial and inner layers become thicker, which consequently reduces the flexibility of the vessel and increases its rigidity. Deposits of collagen and glycated proteins are also formed in the vessel wall [15]. As shown by the Blue Mountain Eye Study [16], age is an independent risk factor for the reduced diameter of blood vessels.…”

“…The lumen of the vessel is limited by the inner membrane formed by endothelial cells and pericytes attached to the basal membrane. Individual layers are separated from each other by external and internal elastic membranes [1,[14][15][16].…”

Introduction The advances in research methods used in ophthalmology allow for an increasingly accurate examination of the eyes, as well as the morphology and function of the vessels. Colour Doppler imaging is still the first-line method for the analysis of parameters of retrobulbar circulation. Therefore, the aim of this work was to present the current state of knowledge about anatomical and functional age-related changes in retrobulbar arteries. Methods A literature search was performed mainly based on the PubMed database. Results The anatomy of retrobulbar arteries, histological background of age-related vascular changes, age-related changes in retrobulbar blood flow in the ophthalmic artery, central retinal artery, short posterior ciliary arteries, and the reference values for the age-dependent retrobulbar circulation parameters measured by colour Doppler imaging are discussed in this review. Conclusion The age of the subject should always be taken into account when interpreting the parameters of retrobulbar blood flow measured by colour Doppler imaging.

ObjectivesTo investigate the relationship between the mammography‐detected breast arterial calcification (BAC) and orbital color Doppler ultrasonography (CDUS) results.MethodsOur single‐center study, included female patients who applied to our hospital between January and May 2022 and underwent mammography and orbital CDUS examinations. Two radiologists evaluated the mammograms, grouped the patients as BAC (+) and BAC (−), and performed orbital CDUS. Continuous variables obtained from CDUS were compared according to the presence of BAC. Also, receiver operating characteristics (ROC) analysis was used to determine the orbital CDUS threshold values for the presence of BAC.ResultsA total of 119 women were included with a median age of 62 years, 57 (47.90%) had BAC. Orbital CDUS examination was performed on both eyes of 119 patients (238 eyes in total). Peak systolic velocity (PSV) and end‐diastolic velocity (EDV) values of the ophthalmic artery (OA) (P < .001) and EDV of the central retinal artery (CRA) (P < .001) were significantly lower in patients with BAC. Pulsatile index (PI) and resistive index (RI) values of OA (P < .001) and CRA (P < .001) were higher in patients with BAC. In ROC analysis, the cut‐off values for the presence of BAC were calculated as OA PI ≥1.415 and OA RI ≥0.755 (P < .001); CRA PI ≥1.135 and CRA RI ≥0.655 (P < .001).ConclusionsOrbital perfusion disorders may be observed in patients with vascular calcification detected on routine mammography. Therefore, a more detailed evaluation of patients with BAC detected on mammography with orbital CDUS may enable early detection and treatment of ocular vascular problems.

Parameters Characterizing Age-Dependent Retrobulbar Circulation in Healthy Subjects Measured by Color Doppler Ultrasonography

Abstract: CDU has considerable potential for evaluating hemodynamic changes in the retrobulbar circulation in relation to age. Age laboratory standards for a specific CDU device should be established for further analyses of blood flow in ocular diseases of vascular origin.
