Corneal 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 کاملAssociation between Corneal Biomechanical Properties with Ocular Response Analyzer and Also CorvisST Tonometry, and Glaucomatous Visual Field Severity
PURPOSE To investigate the association between corneal biomechanical properties measured with the Ocular Response Analyzer (ORA) and also CorvisST (CST) tonometry, and glaucomatous visual field (VF) severity. METHODS One hundred forty-six eyes of 91 patients with primary open-angle glaucoma who performed Humphrey Field Analyzer 30-2 or 24-2 SITA-Standard, ORA, and CST within 180 days were inc...
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 کاملEvaluation of Corneal Biomechanical Properties Following Penetrating Keratoplasty Using the Ocular Response Analyzer
PURPOSE To evaluate corneal biomechanical properties in eyes that had previously undergone penetrating keratoplasty (PK) using the ocular response analyzer (ORA). METHODS We recruited 26 patients who had received unilateral PK. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and cornea-compensated intraocular pressure (IOPcc) were mea...
