Corneal hysteresis in mucopolysaccharidosis I and VI [PDF]

open access: yesActa Ophthalmologica, 2011
Abstract.Purpose:  High intraocular pressure (IOP) and glaucoma are often suspected in patients with mucopolysaccharidosis (MPS). To determine corneal hysteresis (CH) and IOP in children with mucopolysaccharidosis I‐Hurler (MPS I‐H) and MPS VI.Methods:  Clinical measurements with ocular response analyzer (ORA).Results:  In seven patients, five with MPS

Does corneal hysteresis correlate with endothelial cell density? [PDF]

open access: yesMed Sci Monit, 2015
Background: Our aim was to determine if there is a correlation between corneal biomechanical properties, endothelial cell count, and corneal pachymetry in healthy corneas.Material/Methods: Ninety-two eyes of all subjects underwent complete ocular ...

Effect of topical prostaglandin analogues on corneal hysteresis [PDF]

open access: yesActa Ophthalmologica, 2015
AbstractPurposeTo evaluate possible changes in corneal hysteresis (CH) after topical treatment with a prostaglandin analogue in medication‐naïve eyes.MethodsThis was a prospective, observational cohort study. Sixty‐eight eyes of 68 patients were prospectively included who were newly diagnosed with primary open‐angle glaucoma or ocular hypertension in ...

Biomechanical Properties in Different Types of Thin Corneas in Menoufia Population

open access: yesJournal of Ophthalmology, 2021
Background. To evaluate and compare corneal hysteresis (CH) and corneal resistance factor (CRF) in normal thin (NT) healthy corneas with central corneal thickness (CCT) of 470–500 μm with matched thickness in keratoconus suspect (KCS) and keratoconus (KC)

CHANGES OF BIOMECHANICAL PROPERTIES OF THE CORNEAAFTER CATARACT PHACOEMULSIFICATION

open access: yesAlʹmanah Kliničeskoj Mediciny, 2016
Background: Cataract phacoemulsification is accompanied by changes in biomechanical parameters of the eye. Corneal hysteresis is a characteristic of viscoelastic properties of the cornea which may be studied in vivo. Aim: To assess the changes of corneal

Evaluation of corneal biomechanical properties in spherical and toric soft contact lens wear

open access: yesMedical Journal of Dr. D.Y. Patil Vidyapeeth, 2022
Purpose: Corneal hysteresis (CH) and corneal resistance factor was found to be less for patient wearing toric contact lens as compared to soft spherical CH was calculated as the difference in air pressures between force-in applanation (P1) and force-out ...

Central Corneal Thickness and Corneal Hysteresis Together with Corrected Intraocular Pressure in Normal Population [PDF]

open access: yesAl-Azhar International Medical Journal, 2023
Background: Cornea is the transparent window on the front of the eye with a dome shape. The cornea forms the anterior part of the eye outer coat. This coat's primary function is to protect the intra ocular components.

Mathematical modeling of corneal hysteresis

open access: yesRussian journal of biomechanics., 2023
Mathematical modeling of the deformation of the eyeball under the external pressure applied to the cornea in a bounded area and gradually increasing and then decreasing according to a given law is performed. This relationship corresponds to the change in applied pressure in the ocular response analyzer (ORA) used in clinic.
