Biomechanical parameters of the cornea measured with the Ocular Response Analyzer in normal eyes
BACKGROUND To evaluate the relationships between Reichert Ocular Response Analyzer (ORA) parameters corneal hysteresis (CH) and corneal response factor (CRF) and ocular dimensions, age and intraocular pressure. METHODS Two hundred and twelve eyes of 212 participants with no ocular pathology had CH and CRF measured with the ORA. Intraocular pressure (IOP) was measured with the Dynamic Contour ...
متن کاملCorneal thickness- and age-related biomechanical properties of the cornea measured with the ocular response analyzer.
PURPOSE The Ocular Response Analyzer (ORA) is a new instrument that measures the corneal biomechanical response (corneal hysteresis, CH) to rapid indentation by an air jet. CH is the difference in applanation pressures (P1, P2) between the rising and falling phases of the air jet. The investigation had two parts: a characterization study and a validation study. In the characterization study, th...
متن کاملCorneal hysteresis measured with the Ocular Response Analyzer in normal and glaucomatous eyes.
PURPOSE To identify differences in corneal hysteresis (CH) and central corneal thickness (CCT) between healthy and glaucomatous patients. METHODS Retrospective observational study. One hundred and thirty-three eyes of 75 healthy and 58 glaucomatous patients were included. CH was measured in each patient using Ocular Response Analyzer. CCT was determined by ultrasonic pachymetry. For each pati...
متن کاملOcular Response Analyzer to Assess Age-Related Biomechanical Characteristics of the Cornea in a Taiwanese Population
Purpose: To investigate biomechanical properties of the cornea as measured using a Reichert ocular response analyzer (ORA) in a Taiwanese population. Methods: Basic demographic data were recorded for 1875 Taiwanese subjects. Corneal hysteresis (CH), corneal resistance factor (CRF), central corneal thickness (CCT), Goldmann-equivalent intraocular pressure (IOPg), and corneal-compensated intraocu...
متن کاملthe correlation between biomechanical properties of normal cornea with tomographic parameters of pentacam
purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...
