Corneal 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 کاملCorneal hysteresis in patients with glaucoma-like optic discs, ocular hypertension and glaucoma
BACKGROUND To compare corneal hysteresis (CH) measurements between patients with glaucoma, ocular hypertension (OHT) and glaucoma-like optic discs (GLD)- defined as a cup to disc ratio greater than or equal to 0.6 with normal intraocular pressure (IOP) and visual fields. The secondary aim was to investigate whether corneal resistance factor (CRF) and central corneal thickness (CCT) differ betwe...
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 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...
