Abstract:PURPOSE. To describe the application of scanning acoustic microscopy in the GHz-range (GHz-SAM) for qualitative imaging and quantitative characterization of the micromechanical properties of the Descemet's membrane and endothelial cells of cornea tissue. METHODS. Investigated were samples of a normal tissue and a tissue with Fuchs' endothelial dystrophy (FECD, cornea Guttata). Descemet's membranes were fixed on glass substrates and imaged utilizing a focused acoustic lens operating at a center frequency of 1 G… Show more
“…V R is related to the velocity of the shear and compressional waves propagating in isotropic samples for the same Possion’s ratio ( Briggs, 1992 ; Li and Feng, 2016 ). Therefore slower V R in regions closer to the weld lines indicate lower compression and shear moduli and consequently lower Young’s modulus than regions located within further distances ( Ahmed Mohamed et al, 2018 ). These findings are consistent with reported low rigidity near weld lines.…”
