THE RELATIONSHIP BETWEEN CCT AND IOP READINGS Others report no linear correlation between CCT and IOP, pointing out that models are dependent on: population characteristics presence/absence of OHT number and type of surgical interventions ethnic groups pachymetric techniques depending on the corneal pachymetric method adopted, may not be able to confirm the true IOP of subjects tonometric techniques each can over or under estimate IOP
THE REICHERT OCULAR RESPONSE ANALYZER® (ORA) The ORA utilizes an air pulse to apply force to the cornea and an advanced electro-optical system to monitor the resultant corneal deformation. Alignment to the patient’s eye is fully automated. The difference between "inward" applanation pressure and "outward" applanation pressures defines corneal hysteresis, a measure of ocular rigidity. RORA measurement may not be possible in the presence of nystagmus
