The basic electrical model of the human eye can be distorted analogously to the distortion occasioned by the suction cup procedure. By using the values for the facility of outflow (C) and for stress relaxation (RQ) determined by tonography, the output of the model matches the clinically observed data when suitable adjustments are made for flow (F) and episcleral venous pressure (Pv). From such a match the following information is elicited: (1) flow is uniquely determined and thereby Pv is obtained by calculation, (2) the decay curve confirms the values for C, RQ, F and Pv, and, (3) the time necessary for the re-establishment of full episcleral venous pressure appears, in some cases, to be in the order of several minutes.
