Comparisons of intraocular pressure measurements: Goldmann applanation tonometry, noncontact tonometry, Tono-Pen tonometry, and dynamic contour tonometry

摘要: To compare intraocular pressure (IOP) readings between Tono-Pen tonometry and GAT, noncontact (NCT) dynamic contour (DCT) Goldmann applanation (GAT). The correlation IOP reading possible confounder was identified. This observational cross-sectional study enrolled sixty-two healthy subjects. All ocular pulse amplitude (OPA) measurements were taken by a single ophthalmologist; mean keratometric power (MK), central corneal thickness (CCT), lens (LT) measured experienced technician. Stepwise multiple regression analysis indicated that GAT (P=0.017) DCT (P=0.002) correlated positively with MK; NCT, CCT (P<0.05); NCT (P=0.035), (P=0.016) negatively LT; (P=0.006) (P=0.009) OPA. K, CCT, LT, OPA are confounders in readings.
