Videomicroscopic investigation of the microcirculation requires uniform definitions

On article : Wright IM, Latter JL, Dyson RM, Levi CR, Clifton VL. Videomicroscopy as a tool for investigation of the microcirculation in the newborn. Physiol Rep. 2016;4(19):e12941 Dear Editor, We would like to compliment Wright et al. (2016) for their extensive data which can aid ongoing research in a very important field and like to share a number of important considerations. Multiple generations of video microscopy techniques are available for the assessment of the microcirculation. The first video microscopy technique is based on orthogonal polarization spectral (OPS) imaging (Groner et al. 1999). The reported Microscan (Microvision Medical) is a second generation video microscopy which operates with sidestream dark field (SDF) imaging (Goedhart et al. 2007). This technique is superior to OPS imaging in capillary contrast and quality (Groner et al. 1999). However, unlike stated in …
