2016, UltrasonicsCitation Excerpt :Ultrasonic methods were reported previously for the measurement of corneal biomechanical properties. Corneal speed of sound can be measured to analyze the corneal properties [21]. Aggregate modulus can be calculated based on the speed of ultrasound to determine the change of corneal mechanical properties [22].
Manipulation of intraocular pressure for studying the effects on accommodation
2012, Experimental Eye ResearchCitation Excerpt :The CUB records the time between the peaks and the times were converted to actual distances by multiplication with accepted sound velocities of 1532 m/s for the aqueous and vitreous and 1641 m/s for the lens (van der Heijde and Weber, 1989; Vilupuru and Glasser, 2005). Sound velocities for the pig eyes have been reported to be almost identical to that of human eyes at room temperature (Thijssen et al., 1985) although the sound velocity of the lens can vary with age and is lower in the lens nucleus (Huang et al., 2007). The complete experimental setup is shown in Fig. 2.
Variance of Speed of Sound and Correlation with Acoustic Impedance in Canine Corneas
2011, Ultrasound in Medicine and BiologyCitation Excerpt :The CCT (568 ± 68 μm) measured with a clinical pachymeter was comparable to those reported from in vivo studies in canine eyes (Gwin et al. 1982; Gilger et al. 1991) indicating minimal swelling of the corneas. The speed of sound in the canine corneas, 1577 ± 10 m/s, was similar to that in porcine corneas (Thijssen et al. 1985; de Korte et al. 1994; Kampmeier et al. 2000; He and Liu 2009), bovine corneas (Oksala and Lehtinen 1958; Silverman et al. 2009) and human corneas measured postmortem (Rivara and Sanna 1962; Thijssen et al. 1985; de Korte et al. 1994; Ye et al. 1995). This value was lower than what is assumed for human corneas for in vivo measurements, even if the temperature effect is corrected for (the measurements were performed at room temperature while in vivo measurements are done at body temperature) (Thijssen et al. 1985).
