CENTRAL THICKNESS IN CORNEAL DISORDERS
Acta Ophthalmologica, 1978In 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 ...

Effect of Brimonidine on Corneal Thickness
Journal of Ocular Pharmacology and Therapeutics, 2011Brimonidine, an alpha-2 adrenoceptor agonist, is an effective and safe medication that is widely used in glaucoma treatment. Although it is known that it is quickly taken up by the cornea following topical administration and that the cornea has alpha-2 adrenoceptors, there are only few studies available on the impact brimonidine has on the cornea ...

Diurnal variation in corneal thickness
Experimental Eye Research, 1973Abstract Corneal thickness was measured at three different times of day in rabbits. The rabbit cornea showed a significant diurnal variation regarding thickness. In most cases, the cornea was thickest in the forenoon, and then thinning followed. It usually became thinnest in the afternoon, but sometimes at about noon.

Effect of phacoemulsification on corneal thickness
American Journal of Ophthalmology, 2003To determine the immediate effect on corneal thickness of cataract extraction using phacoemulsification.Prospective consecutive nonrandomized humans undergoing standard small-incision phacoemulsification and intraocular lens insertion.Corneal thickness was measured immediately preoperative and postoperatively in 58 consecutive patients undergoing ...

CORNEAL THICKNESS CHANGES ACCOMPANYING CENTRAL CORNEAL CLOUDING
Optometry and Vision Science, 1971ABSTRACT Corneal thickness measurements were made before and after central corneal clouding was caused by a tightly fitted contact lens. The area of corneal thickening corresponded to the observed area of central corneal clouding.

The effect of corneal thickness and corneal curvature on pneumatonometer measurements
Current Eye Research, 2002The purpose of this study was to investigate the influence of corneal topography and thickness on intraocular pressure (IOP) and pulse amplitude (PA) as measured using the Ocular Blood Flow Analyzer (OBFA) pneumatonometer (Paradigm Medical Industries, Utah, USA).47 university students volunteered for this cross-sectional study: mean age 20.4 yrs, range

A simple technique for measurement of corneal thickness
Contact Lens and Anterior Eye, 1998Measurement of corneal thickness has potential benefit both in the fitting of contact lenses and in monitoring any pathology that could affect corneal thickness. Corneal thickness measurement is undertaken using an accessory to the biomicroscope, the optical pachometer, or by means of expensive apparatus such as the ultrasonic pachometer.
