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 کاملTonometry in corneal edema after cataract surgery: dynamic contour tonometry versus Goldmann applanation tonometry
INTRODUCTION Intraocular pressure (IOP) determination using dynamic contour tonometry (DCT) has been considered to be independent of central corneal thickness (CCT), while Goldmann applanation tonometry (GAT) is known to be influenced by various corneal properties. In this study, IOP was measured before and 1 day after cataract surgery using GAT and DCT to investigate the possible effects of co...
متن کاملElectronic applanation tonometry in corneal edema and keratoplasty.
The effect of corneal edema and the effect of penetrating keratoplasty upon the accuracy of electronic applanation tonometry were studied in rabbits. Pressure readings made directly from cannulas in the anterior chamber correlated well with those made by electronic applanation tonometry both in severe corneal edema and 24 hours after penetrating keratoplasty. The advantages of electronic applan...
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...
