Effect of central corneal thickness, corneal curvature, and axial length on applanation tonometry.
OBJECTIVE To evaluate the effect of central corneal thickness (CCT), corneal curvature, and axial length on applanation tonometry in an in vivo study. METHODS In a masked, prospective clinical trial, we examined 125 eyes of 125 patients scheduled for cataract surgery. Corneal curvature was measured by means of keratometry and axial length by A-scan ultrasonography. By cannulating the anterior...
متن کاملCentral corneal thickness and applanation tonometry.
after sub-Tenon anesthesia In their recent article, 1 Subbiah et al. noted that a rigid sub-Tenon cannula caused complications such as a retrobulbar hemorrhage, albeit rarely. The authors concluded that a ‘‘soft cannula’’ could be an ideal alternative for sub-Tenon injection in high-risk patients. We reported the same thing in our Sandwell technique, in which the soft plastic sheath of a Venflo...
متن کاملComparison of Goldmann applanation tonometry and Pascal dynamic contour tonometry in relation to central corneal thickness and corneal curvature
PURPOSE The aim of the study was to assess the influence of central corneal thickness (CCT) and corneal curvature in tonometry measurements taken by Goldmann applanation tonometry (GAT) and Pascal dynamic contour tonometry (DCT). METHODS This was a prospective study of 185 eyes from 97 subjects, attending outpatient ophthalmology appointments, who underwent intraocular pressure measurements b...
متن کاملRelationship between central corneal thickness, refractive error, corneal curvature, anterior chamber depth and axial length.
BACKGROUND To determine the relationship between central corneal thickness (CCT), refractive error, corneal curvature, anterior chamber depth and axial length in normal Taiwanese Chinese adults. METHODS Five hundred normal Taiwanese Chinese patients aged 40-80 years were recruited for the study. Measurement procedures included CCT, refractive error, corneal curvature, anterior chamber depth a...
متن کاملEffect of central corneal thickness on dynamic contour tonometry and Goldmann applanation tonometry in primary open-angle glaucoma.
OBJECTIVE To compare the dependence of dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) on central corneal thickness (CCT) in primary open-angle glaucoma. METHODS In a prospective study, the interocular (right vs left eye) difference in intraocular pressure measured by DCT and GAT was compared with the interocular CCT difference in 125 patients with primary open-angle ...
