[Tonography and fluorophotometry in the clinical study of aqueous humor dynamics]

We used Grant's tonography and fluorophotometry (the Jones and Maurice method) to study the aqueous humor dynamics in normal and glaucomatous eyes. The results of the two methods were compared. The mean facility and rate of aqueous flow in normal eyes were similar. In glaucomatous eyes the tonographic outflow facility (C-value) varied greatly, and the calculated rate of aqueous flow (F-value) also had a large standard deviation. To study the inflow rate, fluorophotometry is a more accurate method. Further calculation of uveoscleral flow and the "pseudofacility" from the tonographic F-value and fluorophotometric C-value was therefore of only limited accuracy.
