We hope to one day restore vision lost from glaucoma, but that can't presently be done. Existing treatments slow the process for most patients so no meaningful vision loss occurs in their lifetime. There are, however, several potential avenues to a cure.e hope to one day restore vision lost from glaucoma, but that can't presently be done.

Paracentesis is a procedure in which a needle or catheter is inserted into the peritoneal cavity to obtain ascitic fluid for diagnostic or therapeutic purposes.Ascitic fluid may be used to help determine the etiology of ascites, as well as to evaluate for infection or presence of cancer.
Paracentesis: The removal of fluid from a body cavity via a needle, a trocar, a cannula, or another hollow instrument. A paracentesis may be used for diagnosis or treatment, as, for example, in ascites, where there is free fluid in the abdominal (peritoneal) cavity. If the cause of the ascites is uncertain, diagnostic paracentesis is done in order to obtain fluid that can be examined. Therapeutic paracentesis may then be done to remove more fluid, as part of the plan of treatment. Paracentesis of the chest cavity is called a thoracentesis. Last Editorial Review: 3/19/2012.
