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 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 کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

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 ...
