8. Optical Coherence Tomography Angiography Vessel Density Changes after Acute Intraocular Pressure Elevation
  
  Explore Nature Publishing Group Apr 26 2018 Ophthalmology
  
  To investigate changes in retinal vessel density in optic nerve head (ONH) and macula after acute intraocular pressure (IOP) elevation, we conducted a prospective observational study. Eyes with IOP rise 5mmHg after 2-hour dark room prone provocative test (DRPPT) were included. Vasculature of ONH and macula was examined by optical coherence tomography angiography (OCTA) at baseline and after DRPPT. Among the 65 eyes of 42 individuals, 40 eyes with qualified ...

  To the Editor: A 73-year-old female was referred to our hospital for evaluation of unstable angina pectoris. She had a greater than 10-year history of hypertension. Coronary angiography (CAG) was performed in another hospital in March 2017, which showed diffuse calcific stenosis (about 90%) in the proximal and mid-left anterior descending (LAD) artery, 70% stenosis in the ostial obtuse marginal branch, and no apparent stenosis in the right coronary artery ...

  arginal gap (MG) was the most important factor to evaluate the success of crowns. The study was to assess the MG of lithium disilicate glass ceramic crowns with spectral domain optical coherence tomography (OCT) and stereomicroscopy in vitro , and to provide evidence to measure the MG with OCT. Consistency was observed between OCT and stereomicroscopy to measure the MG after cementation. There was no significant difference between the MG of ...

  Biomechanical properties are important for the cornea to maintain its normal shape and function. There is still a need to develop better methods for accurate measurement of corneal mechanical properties. In this study, we propose to introduce the optical coherence tomography (OCT) in inflation test for the imaging of corneal deformation in order to measure its biomechanical properties. Ten cornea-mimicking silicone phantoms with different stiffness and five fresh porcine corneas ...

13. Measurement of the absolute velocity of blood flow in early-stage chick embryos using spectral domain optical coherence tomography
  
  Explore OSA | OSA Publishing Oct 31 2017 Developmental Biology
  
  Doppler optical coherence tomography (OCT) is a noninvasive imaging modality that provides quantitative flow information with high spatial and temporal resolution. However, it is only sensitive to the flow velocity vector parallel to the incident beam. To calculate the absolute velocity, it is necessary to obtain the angle between the incident beam and flow field. In this paper, we describe a practical method to measure the Doppler angle based on ...
