      Aging-associated changes in cerebral vasculature and blood flow as determined by quantitative optical coherence tomography angiography
      Capillary velocity increases by 21% and velocity heterogeneity increases by 19% with older age. Abstract Normal aging is associated with significant alterations in brains vascular structure and function, which can lead to compromised cerebral circulation and increased risk of neurodegeneration. The in vivo examination of cerebral blood flow (CBF), including capillary beds, in aging brains with sufficient spatial detail remains challenging with current imaging modalities. In the present study, we ...

      Use of Optical Clearing Agents for Imaging Root Surfaces With Optical Coherence Tomography
      The diagnosis of root caries and root fractures is of increasing importance due to our aging population. The objective of this study is to show that optical clearing agents can be used to increase the visibility of subsurface structures in tooth roots to aid in the diagnosis of root caries depth and extension and to differentiate from subsurface defects. Previous studies have shown that high refractive index fluids can increase ...

      Purpose : To assess the interdevice agreement between swept-source Fourier-domain and time-domain anterior segment optical coherence tomography (AS-OCT). Methods : Fifty-three eyes from 41 subjects underwent CASIA2 and Visante OCT imaging. One hundred eightydegree axis images were measured with the built-in two-dimensional analysis software for the swept-source Fourier-domain AS-OCT (CASIA2) and a customized program for the time-domain AS-OCT (Visante OCT). In both devices, we examined the angle opening distance (AOD), trabecular iris ...

      Lesion dehydration rate changes with the surface layer thickness during enamel remineralization
      A transparent highly mineralized outer surface zone is formed on caries lesions during remineralization that reduces the permeability to water and plaque generated acids. However, it has not been established how thick the surface zone should be to inhibit the penetration of these fluids. Near-IR (NIR) reflectance coupled with dehydration can be used to measure changes in the fluid permeability of lesions in enamel and dentin. Based on our previous ...

      Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study
      Background Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without optic neuritis available. Methods In this multicentre, cohort study ...

      Scientists look FTD in the eye
      A routine eye test may help clinicians identify early signs of at least one form of FTD according to a new study published on April 12 in Science Translational Medicine. The study, led by Li Gan and Ari Green at the University of California in San Francisco, found that people heterozygous for progranulin (GRN) mutations without cognitive symptoms exhibited twice the number of lipid-rich deposits, known as lipofuscin, in the ...
