PURPOSE To investigate age-related differences in central and peripheral corneal thickness in humans with univariate and multivariate regression analyses. METHODS Orbscan II (Bausch & Lomb, Inc., Rochester, NY) pachymetry was used to assess the cornea in healthy, white European subjects. A corneal thickness profile across an 8-mm chord along the horizontal meridian was generated at 0.5-mm int...

PURPOSE To compare Orbscan II and ultrasonic pachymetry for measurement of central corneal thickness (CCT) in eyes scheduled for keratorefractive surgery. METHODS CCT was measured using Orbscan II (Bausch & Lomb, USA) and then by ultrasonic pachymetry (Tomey SP-3000, Tomey Ltd, Japan) in 100 eyes of 100 patients with no history of ocular surgery scheduled for excimer laser refractive surgery....

PURPOSE To identify relationships between central corneal thickness (CCT) and optic disc topography, as determined by scanning laser ophthalmoscopy (SLO), for patients seen in a specialist glaucoma service. METHODS 272 eyes of 144 patients with primary open angle glaucoma (POAG; n = 71), normal tension glaucoma (NTG; n = 50), ocular hypertension (OH; n = 48) and those considered to be suspici...

We examined prospectively 60 healthy volunteers to evaluate if the accuracy of central corneal thickness (CCT) measurement is influenced by Goldmann applanation tonometry (GAT) and vice versa. The sequence of the examinations in the right eye was CCT--GAT--CCT, in the left eye GAT--CCT--GAT and the measurements were done consecutively. Two tonometry and five pachymetry measurements were average...

OBJECTIVE The evaluation of central corneal thickness (CCT) in subjects with pesudoexfoliation glaucoma (PEXG), primary open-angle glaucoma (POAG), and in normotensive individuals with or without pseudoexfoliation syndrome (PXS). STUDY DESIGN/PATIENTS AND METHODS CCT was evaluated with ultrasound pachymetry in a total of 179 individuals: 32 had bilateral PEXG, 55 had bilateral POAG, 35 had PX...

Background/aim: To compare intraocular pressure (IOP) measurements taken by the Goldmann applanation tonometer, the Tono-Pen and the ocular blood flow pneumotonometer in eyes with varying central corneal thickness (CCT) due to penetrating keratoplasty (PK), keratoconus (KC), and Fuchs’ endothelial dystrophy (FED). Methods: IOP was measured with the Goldmann applanation tonometer, Tono-Pen XL, a...

Background: Central Corneal Thickness (CCT) is an indicator of corneal health status as well being essential tool in assessment and management diseases. It important factor the diagnosis glaucoma it affects measurement intraocular pressure. However, pattern central thickness our population not known. Our study aimed to describe CCT measurements their variation with age sex among patients attend...

purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...

Background: Corneal changes occur as a direct consequence of diabetes mellitus (DM). The central corneal thickness (CCT) is useful parameter that provides information about the status metabolism cornea and can therefore help monitor progression DM.Aim: aim this study was to determine impact DM on CCT its correlation with duration glycated haemoglobin (HbA1c) levels.Methods: systematic review un...

The purpose of this study was to determine the repeatability and reproducibility of post-mortem central corneal thickness (CCT) measurements by using a real-time, portable optical coherence tomography (OCT) system on an animal model, and to prospectively evaluate the time-course of post-mortem changes in CCT. Forty-six ocular globes of sheep (Ovis aries) were analyzed with a portable spectral-d...
