Contact and noncontact signals from an embedded eyeball. (a) Power spectra for the contacting eyeball test. Arrows indicate the resonant frequencies of various IOP levels. (b) Statistical results relating amplitude differences and IOP levels. (c) Power spectra for the noncontact eyeball test. (d) Statistical model relating amplitude differences and IOP levels.
