Correlation between central corneal thickness and intraocular pressure in various age groups.
INTRODUCTION The Pascal Dynamic Contour Tonometer (DCT) is an ophthalmic investigational device which directly calculates the dynamic pulsatile fluctuations in intraocular pressure (IOP) using a piezoelectric pressure sensor embedded in the devices tip. OBJECTIVE The aim of this study was to compare IOP results obtained with Goldmann applanation tonometer (GAT), and their correlation with cen...
متن کاملComparison of Corneal Epithelial and Stromal Thickness Distributions between Eyes with Keratoconus and Healthy Eyes with Corneal Astigmatism ≥2.0 D
PURPOSE To identify corneal epithelial- and stromal-thickness distribution patterns in keratoconus using spectral-domain optical coherence tomography (SD-OCT). PATIENTS AND METHODS We analyzed SD-OCT findings in 20 confirmed cases of keratoconus (group 1) and in 20 healthy subjects with corneal astigmatism ≥ 2 D (group 2). Epithelial and stromal thicknesses were measured at 11 strategic locat...
متن کاملA Clinical Study on the Correlation Between Axial Length, Intraocular Pressure and Central Corneal Thickness in Myopic Eyes
Introduction: Myopia or short sightedness, is that form of refractive error wherein parallel rays of light come to a focus in front of the sentient layer of the retina when the eye is at rest; the eye is thus relatively too large, and the condition is the opposite to that of hypermetropia. Aims and objectives of the research were to find out whether there is a correlation between axial length, ...
متن کاملretinal nerve fiber layer thickness and physiological central corneal thickness in healthy myopic eyes
purpose: to examine the relationship between retinal nerve fiber layer (rnfl) measurements obtained using scanning laser polarimetry with variable corneal compensation (vcc) and central corneal thickness (cct) measurements using pentacam in myopic patients methods: the study included 45 eyes from 45 myopic patients with intraocular pressure (iop) measurements≤21 mmhg. all participants had norma...
متن کامل[Post-lasik corneal ectasia in patients with significant differences in keratometry readings between both eyes].
OBJECTIVES A study is made on the incidence of corneal ectasia after laser in situ keratomileusis (LASIK) in patients with large differences in mean keratometry (MK) readings between both eyes (OU). Visual outcomes were also evaluated. METHODS The medical records of 164,603 patients (315,259 eyes) who underwent LASIK from January 2003 to December 2011 were reviewed in order to identify patien...
