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.
Therapeutic paracentesis may be performed in patients who require rapid symptomatic relief for refractory or tense ascites. When small volumes of ascitic fluid are removed, saline alone is an effective plasma expander. The removal of 5 L of fluid or more is considered large-volume paracentesis. Total paracentesis, that is, removal of all ascites (even >20 L), can usually be performed safely.
