The iFalcon V100 tonometer provides accurate central corneal IOP measurements in normal canine eyes within the physiological range of 5-50 mmHg, showing good agreement with direct implantable pressure sensor readings. Although the validated 5-50 mmHg range is wider than normal physiological pressures and encompasses commonly encountered pathological levels, we did not evaluate performance at 70-80 mmHg levels occurring in acute glaucoma, which is a study limitation.
Su et al. (Sun,) studied this question.
