Central corneal thickness in southern Egypt

International Ophthalmology, 2013
The study aimed to determine mean central corneal thickness (CCT) in a southern Egyptian population according to gender and age using ultrasonic pachymetry and to compare these CCT measurements to different populations. A prospective, observational, consecutive case series of 4,368 non-glaucomatous subjects (emmetropes and myopes) aged 16-70 years was ...

Central Corneal Thickness Measurement in Clinical Practice

Journal of Glaucoma, 2005
To determine if a single measurement of central corneal thickness (CCT) is an adequate sample to aid in glaucoma risk assessment in clinical practice.Central corneal thickness was measured by ultrasound pachymetry (mean of 15 measurements for each eye) on two separate occasions at least one month apart (range, 33 to 610 days).

Ocular Hypertension and Central Corneal Thickness

Ophthalmology, 1995
To determine whether ocular hypertension (OHT) is over diagnosed in patients with increased corneal thickness.Thirty-six patients with OHT were compared with 29 control subjects and 31 patients with glaucoma. Corneal thickness was determined by ultrasonic pachymetry and measured at a single point, 1.5 mm temporal to the corneal light reflex.The corneal

Central corneal thickness in full‐term newborns

Acta Ophthalmologica, 1989
Abstract The central corneal thickness (CCT) was measured in 30 full‐term newborns in the first week post partum using ultrasonic pachometry. The mean CCT in the right eyes was 0.581 ± 0.047 mm. In 19 babies the CCT was measured twice. The mean CCT in the second reading was 0.584 ± 0.042 nun. This difference was not statistically significant. There was

Measuring Central Corneal Thickness with Ultrasound Pachymetry

Optometry and Vision Science, 2003
To determine how many ultrasound pachymetry measurements are required to obtain a reasonable estimate of central corneal thickness.Five central corneal thickness measurements were obtained from each eye of 101 patients with normal corneas. The means of fewer than five readings were compared with the mean of five values for each eye to determine the ...

IOP: Central Corneal Thickness

2009
Ever since the recognition that glaucoma was associated in many patients with a firm eye, ophthalmologists have been attempting to measure intraocular pressure (IOP) clinically. Prior to the introduction of Goldmann Applanation Tonometry (GAT) in the 1950s, tonometry techniques were inconvenient and unreliable.

Central Corneal Thickness: Congenital Cataracts and Aphakia

American Journal of Ophthalmology, 2007
To evaluate central corneal thickness (CCT) in normal children (controls) and in those with cataracts, pseudophakia, and aphakia.Prospective, observational case series.CCT was measured in 369 eyes of 223 children. Subjects with glaucoma, anterior segment abnormalities, or intraocular pressure of more than 30 mm Hg were excluded.

CENTRAL CORNEAL THICKNESS IN NEWBORNS AND CHILDREN

Acta Ophthalmologica, 1976
Central corneal thickness was measured optically in premature and full‐term babies, and in children. The thickness was found to decrease from the values found in premature and full‐term babies to those found in small children aged between 2–4 years. The thickness of the adult cornea is reached at the age of about 3 years.These findings are discussed ...

Central corneal thickness: Will one measurement suffice?

Ophthalmology, 2005
To evaluate the measurement of central corneal thickness (CCT) in a cohort of glaucoma patients over a 3-month period. Measurements were then applied to the criteria described in the Ocular Hypertension Treatment Study (OHTS).Cohort study.Fifty-one patients were recruited from a glaucoma clinic at Moorfields Eye Hospital.

CENTRAL CORNEAL THICKNESS IN LOW‐TENSION GLAUCOMA

Acta Ophthalmologica, 1974
Significantly reduced central corneal thickness is reported in seven patients with low tension glaucoma. This finding, together with previously reported findings of increased thickness in ocular hypertension (suspicio glaucomatis) illustrates the clinical importance of the corneal thickness in the evaluation of border line glaucoma.
