DEFINITION

Classification: 600/398

Testing aqueous humor pressure or related condition:

(under subclass 300) Subject matter in which the amount of force exerted by a clear, lymph-like fluid located in the chamber in an eye between a cornea and a lens therein for evaluating a condition which causes an abnormal force to be exerted in said chamber is assayed.
