Central 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 کاملThe relative effects of corneal thickness and age on Goldmann applanation tonometry and dynamic contour tonometry.
AIMS To establish the effects of central corneal thickness (CCT) on intraocular pressure (IOP) measured with a prototype Pascal dynamic contour tonometer (DCT), to evaluate the effect of CCT and age on the agreement between IOP measured with the Pascal DCT and Goldmann applanation tonometer (GAT), and to compare the interobserver and intraobserver variation of the DCT with the GAT. METHODS GA...
متن کاملEffect 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 کاملCorrelation between central corneal thickness, applanation tonometry, and direct intracameral IOP readings.
BACKGROUND Several authors reported incorrect high intraocular pressure (IOP) values in eyes with a thick cornea using applanation tonometry. This hypothesis was checked by comparing applanation tonometry with direct intracameral manometry. METHODS 73 patients, scheduled for intraocular surgery, were enrolled. Immediately before surgery, the following were registered: (i) central corneal thic...
