Blind spot in ultrasound central corneal thickness measurement – Central corneal thickness of apex versus central corneal thickness of vertex

open access: yesKerala Journal of Ophthalmology, 2023
Aims: This study aimed to compare central corneal thickness (CCT) using ultrasound pachymetry (USP) (CCT apex) and specular microscopy (CCT vertex) and also to find out the intra-reading variability from the two instruments. Settings and Design: A prospective, observational study ...

Comparison of corneal thickness in patients with dry eye disease using the Pentacam rotating Scheimpflug camera and anterior segment optical coherence tomography.

open access: yesPLoS ONE, 2020
The purpose of this study was to compare central corneal thickness, thinnest corneal thickness, and the thinnest point of the cornea between Pentacam and anterior segment optical coherence tomography (ASOCT) in patients with dry eye disease (DED).

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 ...

Intraocular pressure in a cohort of healthy Eastern European schoolchildren: variations in method and corneal thickness [PDF]

open access: yes, 2012
BACKGROUND: Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Measurements are needed on many cohorts of children with different

Corneal epithelial thickness analysis of forme fruste keratoconus with optical coherence tomography [PDF]

open access: yesInternational Journal of Ophthalmology, 2021
AIM: To explore the significance of corneal epithelial thickness analysis in diagnosing early keratoconus. METHODS: There were 26 clinical keratoconus, 21 forme fruste keratoconus, 40 high corneal astigmatism (ΔK) and 40 low ΔK eyes involved in the study.

Central Corneal Thickness in Latinos

open access: yesInvestigative Opthalmology & Visual Science, 2003
To characterize central corneal thickness (CCT) in Latinos aged 40 or more years.A population-based cohort of Latinos from two census tracts in La Puente, California, underwent measurements of CCT and intraocular pressure (IOP). CCT was measured with an ultrasonic pachymeter, and IOP was measured by applanation tonometry.

Intraocular pressure and central corneal thickness in a healthy student population [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo
Introduction/Objective. Intraocular pressure is an important parameter of eye health, especially when glaucoma is suspected. So far, few studies have been published that aimed to determine the average value of intraocular pressure and central corneal ...
