Class Information
Number: 600/405
Name: Surgery > Diagnostic testing > Testing aqueous humor pressure or related condition > Measuring force required to produce standard or measured eye flattening (applanation)
Description: Subject matter including means for measuring the force required to press a flat area on the normally curved surface of the eye, the area being of a standard size (e.g., an area of known size marked on the end of a transparent pressure-applying rod) or being measured so that pressure within the eye can be derived by means of the equation: Force = (Pressure)(Area)).
