To determine the agreement between dynamic contour tonometer (DCT), Goldmann applanation tonometer (GAT), and Ocular Response Analyzer (ORA) in keratoconic corneas and to find out the effect of corneal biomechanics on intraocular pressure (IOP) measurements obtained by these devices.IOP was measured with the ORA, DCT, and GAT in random order in 120 ...

[Examinations by ocular pressure tonometry].
Klinische Monatsblatter fur Augenheilkunde, 1991A new method has recently been suggested for the determination of the outflow resistance in the anterior chamber angle. In this method the intraocular pressure is set to 45 mmHg for 8 minutes. The intraocular pressure is measured after the removal of the suction cup. Values below 7 mmHg are obtained in healthy subjects.

Ocular Tonometry Through Sonic Excitation and Laser Doppler Velocimetry
Journal of Biomechanical Engineering, 1979Glaucoma is an insidious eye disease which must be detected in its early stages for there to be successful treatment. Primary detection of glaucoma and evaluation of therapy have depended upon tonometric methods which require applanation of the cornea. A new method of IOP determination which is noncontacting and nonapplanating has been devised.

The Clinical Utility of Dynamic Contour Tonometry and Ocular Pulse Amplitude
Journal of Glaucoma, 2007To determine if ocular pulse amplitude (OPA) as measured by dynamic contour tonometry (DCT) is related to severity of glaucoma, and if intraocular pressure (IOP) as measured by DCT is related to central corneal thickness (CCT).Patients were selected from the Duke Eye Center glaucoma clinic.

Intraocular pressure (IOP) is an eye parameter of fundamental importance for the diagnosis of several eye conditions. The clinical standard for IOP measurement is Goldmann applanation tonometry (GAT), which has been the basis for the studies that determined current glaucoma management. Nevertheless, GAT is endowed with a number of limitations, so newer

Evaluation of Goldmann Applanation Tonometry Using a Nonlinear Finite Element Ocular Model
Annals of Biomedical Engineering, 2006Goldmann applanation tonometry (GAT) is the internationally accepted standard for intra-ocular pressure (IOP) measurement, which is important for the diagnosis of glaucoma. The technique does not consider the effect of the natural variation in the corneal thickness, curvature and material properties. As these parameters affect the structural resistance

Fortschritte der Ophthalmologie : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1992
A total of 44 eyes of patients with suspected glaucoma or ocular hypertension were examined both by ocular pressure tonometry (OPT) according to Ulrich and by tonography according to Leydhecker. The visual fields of these eyes were prospectively followed up for 3 years to compare the prognostic value of the two methods. In 30 of the 44 eyes a worsening

Intraocular pressure decrease after local ocular cooling is underestimated by applanation tonometry
International Ophthalmology, 1995The effects of intense systemic or local cooling on aqueous humor dynamics in animals are an increased total outflow facility and a decreased aqueous flow. Few studies suggest that only vasoconstriction of arteriolar segments of the episcleral vasculature may be the cause for a decrease in intraocular pressure after local cooling in humans.
