Figure 2. Correlation between IOP readings obtained by the TonoVet™ tonometer and the actual IOP values. Eyes of two anesthetized monkeys
were cannulated and perfused with BSS. Their IOPs were manipulated by changing the height of the perfusate reservoir. TonoVet™
readings were obtained by a researcher unaware of the actual IOP. A: Examples of individual IOP readings of a randomly selected eye (Eye number: M1R; right eye of monkey M1). Each symbol represents
a single reading. B: Mean IOP values of TonoVet™ tonometer measurements for each of the four tested monkey eyes. M1R and M1L represent the right
and left eye, respectively, of monkey M1. M2R and M2L represent the right and left eye, respectively, of monkey M2.
