Abstract: Apparatus and method are disclosed for indicating and regulating the pressure of a selected body fluid such as an intracranial fluid. An elongated indicator tube is carried at least in part in a vented chamber which can be mounted so that the indicator tube is in a substantially vertical position. A flexible conduit conveys the selected body fluid from a catheter in the patient to the lower end of the indicator tube.

This allows maintenance of normal intraocular pressure during glaucoma surgery. According to the invention, a pressure regulator of the spring-biased diaphragm type is provided with additional bias by a column of liquid.

Liquid is then bled out of the column to reduce the bias on the diaphragm of the pressure regulator and, consequently, the output pressure of the regulator. This lowering pressure of the regulator also occurs in the eye by means of a small second bleed path provided between the pressure regulator and the hypodermic needle.
