In 11 normotensive eyes, numerous ΔV were calculated from corneal applanations of different sizes. To each ΔV the corresponding ΔP was measured by Goldmann's applanation tonometer. Friedenwald's coefficient K, as derived from the results of this study (K a ), was in accordance with the manometries on living eyes of Prijot, Weekers and Ytteborg and definitely smaller than that given by differential tonometry (K t ) performed on the same eye.
