To determine normal central and paracentral corneal thickness measurements in the pediatric population and to determine if these measurements are consistent across different pediatric age groups and different racial groups.Prospective observational case series.Pachymetry measurements were performed on 198 eyes of 108 children.

Corneal Topography and Corneal Thickness in Children
Journal of Pediatric Ophthalmology & Strabismus, 2013Purpose: To evaluate the corneal topography, thickness, and elevation (anterior and posterior corneal surface) in children. Methods: One hundred eyes of 100 patients with a mean ± standard deviation age of 10.6 ± 2.7 years (range: 5 to 15 years) were imaged.

Corneal thickness in congenital glaucoma
American Journal of Ophthalmology, 2004To compare central corneal thickness between eyes with congenital glaucoma and normal controls and to correlate this parameter with corneal diameter and axial length.Eyes of consecutive children with congenital glaucoma with previous glaucoma surgery and eyes of children with inadequacy of lacrimal drainage system with age less than 3 years old were ...

Central corneal thickness and corneal diameter in premature infants [PDF]
Acta Ophthalmologica, 2005 Abstract.Background: Central corneal thickness is significantly greater in full‐term infants than in adults. Very little is known about corneal thickness in premature infants. Methods: Measurements of central corneal thickness and horizontal corneal diameter were carried out in 35 premature babies (70 eyes) undergoing screening for retinopathy of ...

Effect of Corneal Drying on Central Corneal Thickness
Journal of Glaucoma, 2004To determine the amount of corneal thinning induced by corneal drying, and to discuss its possible consequences on applanation pressure.Two sets of central corneal thickness measurement from 100 eyes of 100 patients were taken by ultrasonic pachymeter at time settings of 0, 15, 30, 45, and 60 seconds. During the first set (group 1), patients were asked

BIOMETRIC CORRELATIONS OF CORNEAL THICKNESS
Acta Ophthalmologica, 1975Central corneal thickness, depth of anterior chamber, thickness of lens, length of vitreous, axial length, applanation (Goldmann) and indentation (Schiøtz) tension and rigidity (Friedenwald) were determined in three groups of patients; (1) 16 patients with glaucoma simplex, (2) 25 patients with ocular hypertension, and (3) 26 patients with ...

The Repeatability of Corneal Thickness Measures
Cornea, 2000To compare the repeatability of three measures of corneal thickness: Orbscan Slitscan pachymetry, ultrasound pachymetry, and optical pachymetry.Twenty normal subjects were tested on three occasions. Two occurred on the same day and the third was on a different day at approximately the same time of day as one of the first two visits.

The genetics of central corneal thickness
British Journal of Ophthalmology, 2009Evidence in the recent literature has highlighted the importance of central corneal thickness (CCT) in relation to several ocular and non-ocular conditions. Most notably, thinner CCT has been identified as a risk factor for open-angle glaucoma. Despite having an extensive knowledge of the structure and function of the cornea, little is known about the ...

Ultrasound biomicroscopic corneal thickness measurement for corneal thickness mapping
Japanese Journal of Ophthalmology, 1997Digitalized ultrasound biomicroscopic measurements of vertical cross sections from a 5 mm diameter area of the central cornea of normal and morbid eyes were used to create a computerized corneal thickness map. Mean corneal thickness in normal eyes was 0.503 +/- 0.027 mm; the coefficient of variation, an index of reproducibility, was < 10% in all eyes.
