Capillaroscopy is a non-invasive, efficient, relatively inexpensive and easy-to-learn methodology for directly visualizing capillaries in the microcirculation. However, only one publication to date describes the reliability of a complex software program available for quantitating capillaroscopy data. Here, we present a simple, reliable protocol for quantitating capillaries using a standardized algorithm.

Capillaroscopy is an accessible tool for direct, inexpensive, and non-invasive visualization of microvasculature. The goal of this protocol is to enable researchers to use capillaroscopy for the visualization of peripheral microvascular morphology in the nailbeds of mice.
FAQs
Nailfold capillaroscopy combines magnification and illumination to make the small vessels at the nail base visible, while an immersion medium may be used to support imaging. This setup allows investigators to examine both structural features and blood flow rather than relying only on surface appearance. The resulting view links microvascular anatomy with observable functional behavior.
The most informative observations include capillary shape, density, arrangement, and blood flow, together with dilation, branching, hemorrhages, or disrupted patterns. Evaluating these features gives researchers a structured way to describe microvascular organization and identify departures from an observed pattern. In biology, this supports analysis of how vessel structure and circulation vary under different conditions.
Capillary density and arrangement provide information about the organization of the nailfold microcirculation, while blood-flow observations add a functional dimension. Considering these measures together helps researchers characterize normal microcirculation and investigate vascular responses. This combination is useful because a study can examine not only how vessels are shaped and distributed, but also how circulation appears within them.
A basic examination requires an imaging setup that provides magnification and illumination at the skin near the base of the fingernail. An immersion medium may also be included to support visualization. These elements enable the observer to inspect vessel shape, density, arrangement, blood flow, and visible abnormalities within the nailfold microvascular pattern.
Researchers use this approach to characterize normal microcirculation, investigate vascular responses, and examine patterns associated with systemic disorders such as connective tissue diseases. Its observations can provide information about both vessel structure and blood flow. Consequently, the technique connects basic biological study of microvascular organization with clinical research focused on systemic vascular changes.
Because the examination is painless and repeatable, investigators can use it to observe microvascular findings over time. Serial observations may help characterize disease progression and assess responses to treatment by comparing changes in capillary shape, density, arrangement, blood flow, or disrupted patterns. This makes the method useful for longitudinal research rather than only single-time-point assessment.
