Intra-observer and Inter-observer Variability With Dynamic Contour Tonometry.

Withdrawn

• Conditions: Intraocular Pressure
• Interventions: Device: Dynamic contour tonometry

• Registration Number: NCT00818233
• Lead Sponsor: Yale University

Brief Summary

The aim of the protocol is to document intra-observer and inter-observer variability with dynamic contour tonometry, and will also test the theory that pulse amplitude, as measured by dynamic contour tonometry, is correlated with the difference in systolic and diastolic blood pressures.
