Abstract

Background and objective The corneal biomechanical properties in naïve, untreated glaucoma and ocular hypertension (OHT) eyes is interesting, because it may be a source of error in intraocular pressure (IOP) measurements by Goldmann applanation tonometer (GAT) and ocular response analyzer (ORA). The main objective of this study was to evaluate the IOP values obtained using GAT and the ORA, in primary open angle glaucoma (POAG) and in OHT untreated eyes. Material and methods Observational, masked, cross sectional observational study. Newly diagnosed, untreated POAG and OHT eyes were included. Results Fifty-one POAG and 34 OHT eyes were analyzed. We found that IOPcc (IOP corneal-compensated) was significantly higher than GAT IOP in POAG (P=.0002) while we did not find any significant difference between both tonometers in OHT (P=.1). Conclusions GAT seems to underestimate the real IOP in untreated POAG eyes and it seems to be quite accurate in OHT eyes.
