Assessment of Intraocular Pressure Using Three-Dimensional MR Elastography in Ophthalmologically Normal Individuals

Representative wave images of the x, y, and z components of the vector displacement field as well as elastograms at 90 Hz from four subjects. The intraocular pressure by Goldmann applanation tonometry and the stiffness of the anterior segment were 11 mmHg/2.22 kPa (right) and 10 mmHg/2.05 kPa (left) in the first subject; 14 mmHg/2.62 kPa (right) and 14 mmHg/2.60 kPa (left) in the second subject; 17 mmHg/3.22 kPa (right) and 17 mmHg/2.91 kPa (left) in the third subject; 17.3 mmHg/3.22 kPa (right) and 14.3 mmHg/2.57 kPa (left) in the fourth subject. The dashed lines overlaid on the wave images and elastograms represent the anterior segment and whole eye regions of interest. By Gai et al. (1483–1493)
