Corneal Biomechanical Properties in Rheumatoid Arthritis

Eye & Contact Lens: Science & Clinical Practice, 2015
To investigate the variations in biomechanical properties of the cornea in rheumatoid arthritis (RA) patients.A total of 53 RA patients, and 25 healthy individuals (control group) were enrolled. Rheumatoid arthritis patients were classified as in active phase (group 1; n=24) or in remission phase (group 2; n=29).

Assessment of Corneal Biomechanical Properties and Their Variation with Age

Current Eye Research, 2007
The aim of this study was to determine the stress-strain behavior of corneal tissue and how the behavior was affected by age.Human corneal specimens ranging in age between 50 and 95 years were tested under inflation conditions to determine their stress-strain behavior.

Corneal Biomechanical Properties in Patients With Arcus Senilis

Cornea, 2016
To compare the corneal biomechanical properties and intraocular pressure (IOP) levels in patients with and without arcus senilis (AS).Ocular response analyzer measurements were performed on the right eyes of 37 patients with AS (group 1) and 37 control eyes (group 2).

Hydration dependent biomechanical properties of the corneal stroma

Experimental Eye Research, 2013
The cornea is responsible for about seventy percent of refractive power of the eye and transmits more than ninety percent of the incident light. The refractive power and transparency of the cornea are largely contingent upon active maintenance of its precise curvature and highly regular microstructure.

Corneal biomechanical properties: Precision and influence on tonometry

Contact Lens and Anterior Eye, 2014
To assess the precision and reproducibility of the corneal biomechanical parameters, and their relationships with the intraocular pressure (IOP) measured with the Goldmann tonometer and a noncontact tonometer.Readings for biomechanical properties and for IOP measured with the Goldmann and noncontact tonometers, were taken on one randomly selected eye ...

Effect of ocular biometric factors on corneal biomechanical properties

International Ophthalmology, 2022
To evaluate the effects of ocular biometric variables on corneal biomechanical properties.A total of 102 eyes of 102 participants were enrolled in this cross-sectional study. The axial length (AL) was determined by an IOL master 500 and measurements of corneal biomechanical properties were performed using Corvis ST, integrated with pentacam results ...

Corneal biomechanical properties in normal‐tension glaucoma

Acta Ophthalmologica, 2011
Abstract.Purpose:  To investigate the intraocular pressure (IOP) and corneal biomechanical properties of normal and normal‐tension glaucoma (NTG) eyes.Methods:  This study included 83 normal and 83 NTG eyes. We measured corneal‐compensated IOP (IOPcc), Goldmann‐correlated IOP (IOPg), corneal resistance factor (CRF), corneal hysteresis (CH) and central ...

Corneal Biomechanical Properties during the Menstrual Cycle

Current Eye Research, 2011
To determine if corneal biomechanical properties change during phases of the menstrual cycle.Twenty-five healthy women of reproductive age with no ocular pathology or systemic diseases were recruited. Corneal hysteresis, corneal resistance factor, Goldman-correlated intraocular pressure, and corneal-compensated intraocular pressure were measured by a ...

Corneal Biomechanical Properties of Patients With Pseudoexfoliation Syndrome

Cornea, 2011
To assess the corneal biomechanical properties of patients with pseudoexfoliation syndrome (PEX syndrome).Fifty-two eyes of 52 patients (27 unilateral and 25 bilateral) and 42 eyes of 42 age-matched control subjects were enrolled in the study. Metrics of corneal biomechanical properties, including corneal hysteresis (CH) and corneal resistance factor ...
