Continuous Retinal Vessel Diameter Measurements: The Future in Retinal Vessel Assessment?

Abstract: SDRA shows promise as a tool for the assessment of vessel physiology. Further studies are needed to explore its application in patients with vascular diseases.

“…It is reported to demonstrate the effect of spontaneous variations in vessel diameter that occur under normal resting conditions to flicker light. 38 Tentative links have been made in previous studies between the occurrence of increased arterial diameter fluctuations and the presence of vascular disturbance in both smokers and vasospastic subjects 19,39,40 and between increased retinal venous diameters and the presence of retinal ischemia and hypoxia. 41,42 On this basis, it could be hypothesized that the increased BDF identified in our IGT patients may represent an indicator that common alterations in retinal vascular function may exist in these individuals, perhaps related to an increased variation in vascular tone or compliance.…”

“…Retinal vessel reactivity, in the form of arterial and venous reaction time (RT) and maximum diameter (MD), were determined with our newly defined method of sequential and diameter response analysis (SDRA), which is described elsewhere. 19 In short, SDRA tries to overcome what were considered as shortfalls of the DVA software algorithms and focuses on time and diameter responses for each flicker response as opposed to an averaged response. Furthermore, the fluctuations in baseline diameter are taken into account, thus providing further insight into reaction patterns as a possible tool for the assessment of vessel physiology.…”

“…For example, adaptive optics retinal imaging [111,112], en face optical coherence tomography angiography [113], Doppler optical coherence tomography [114], scanning laser Doppler flowmetry [115], spectral-domain optical coherence tomography [116], and sequential and diameter response analysis [117], are now being studied to further measure and analyse the detailed structure and functions of the retina (including the foveal capillary network, choroidal vasculature, blood flow, choroidal flow, wall:lumen ratio and retinal vessel responses to flickering light). These developments may offer an improved understanding of how early diabetic complications develop and offer improved risk stratification in clinical practice.…”
