Reproducibility and clinical relevance of the ocular response analyzer in nonoperated eyes: corneal biomechanical and tonometric implications.
PURPOSE To assess the reproducibility of the ocular response analyzer (ORA) in nonoperated eyes and the impact of corneal biomechanical properties on intraocular pressure (IOP) measurements in normal and glaucomatous eyes. METHODS In the reliability study, two independent examiners obtained repeated ORA measurements in 30 eyes. In the clinical study, the examiners analyzed ORA and IOP-Goldman...
متن کاملevaluation of corneal biomechanical properties following scleral buckling using the ocular response analyzer
purpose : to evaluate corneal visco-elasticity and intraocular pressure (iop) changes measured by an ocular response analyzer (ora) after scleral buckling methods : fifty-six eyes with history of scleral buckling surgery three months ago were included in the study. corneal hysteresis (ch), corneal resistance factor (crf), corneal-compensated iop (iopcc) and goldmann-correlated iop (iopg) were m...
متن کاملAssessment of corneal biomechanical properties and intraocular pressure with the Ocular Response Analyzer in childhood myopia.
BACKGROUND/AIMS The authors estimated the association between corneal biomechanical properties and axial length in myopic children and verified the relationship between axial length and intraocular pressure (IOP). METHODS This cross-sectional study included 126 eyes of 63 children, aged 12.02+/-3.19 years. Corneal hysteresis (CH), corneal resistance factor (CRF), central corneal thickness (CC...
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...
