Intrasubject Corneal Thickness Asymmetry

Journal of Refractive Surgery, 2008
Purpose To establish the normal distribution for intrasubject (right eye/left eye) central corneal pachymetry in a refractive surgery population. Methods A retrospective analysis was performed on 1448 eyes of 724 consecutive patients evaluated for refractive surgery.

Corneal Thickness in Highlanders

High Altitude Medicine & Biology, 2017
Patyal, Sagarika, Amit Arora, Arun Yadav, and Vijay K. Sharma. Corneal thickness in highlanders. High Alt Med Biol. 18:56-60, 2017.Corneal thickness is an important parameter with diagnostic and therapeutic implications. Various studies have highlighted increase in corneal thickness in lowlanders on ascending to high altitude.

Corneal Topography and Corneal Thickness in Children

Journal of Pediatric Ophthalmology & Strabismus, 2013
Purpose: 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, 2004
To 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 ...

Ultrasound biomicroscopic corneal thickness measurement for corneal thickness mapping

Japanese Journal of Ophthalmology, 1997
Digitalized 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.

Maternal Corneal Thickness During Pregnancy

American Journal of Ophthalmology, 1988
We measured central corneal thickness in 89 pregnant women. It was increased 16 micron (P = .01) compared to the control eyes of 18 nongravid and 17 postpartum women. There was no significant difference (P = .79) in corneal thickness between the nongravid and postpartum groups.

CENTRAL THICKNESS IN CORNEAL DISORDERS

Acta Ophthalmologica, 1978
In the single individual the central corneal thickness (CCT) shows only small variations. Therefore CCT has been studied in a number of corneal diseases in order to investigate if this dimension might contribute to the diagnosis or to the understanding of the pathogenesis.Normal CCT was found in hereditary dystrophies with the exception of the macular ...

Corneal Thickness at High Altitude

Cornea, 2007
The eye, like other organs, is affected by the hypobaric hypoxia of high altitude. Corneal swelling is known to occur under hypoxic conditions at sea level, for instance when wearing contact lenses. The aim of this study was to measure central corneal thickness (CCT) in lowlanders ascending to altitude.The Apex 2 medical research expedition provided ...

Central corneal thickness in glaucoma

Current Opinion in Ophthalmology, 2017
The purpose of this review is to summarize the role of central corneal thickness (CCT) in the clinical management of a glaucoma patient.The prognostic value of CCT is well recognized in patients with ocular hypertension. However, its predictive value in other glaucoma suspects and patients with established glaucoma is less certain.

Corneal thickness and axial length

American Journal of Ophthalmology, 2005
A thin central cornea has been reported to be a risk factor for developing primary open-angle glaucoma among ocular hypertensive eyes. A thin scleral bed of lamina cribrosa seen in deeply excavated optic nerves in glaucomatous eyes is a quintessential finding in advanced glaucomatous eyes. Association between thin cornea and weak sclera contributing to
