Horizontal vs. Vertical Positioning of the iCare Rebound Tonometer and Effects on Intraocular Pressure Readings

Completed · Not applicable

Conditions studied: Intraocular Pressure

In brief

The goal of this study is to evaluate the agreement between intraocular pressure (IOP) measurements taken by iCare, held in both vertical and horizontal positions. In addition, iCare measurements will be compared against pneumotonometry measurements to assess for accuracy.
