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.
A diagnostic paracentesis can be performed in a lean patient with a 1 or 1.5 inch 22-gauge needle, while a 3.5 inch 22-gauge spinal needle can be used for diagnostic paracentesis in an obese patient. For a therapeutic paracentesis, a larger, 15- or 16-gauge needled is used to speed the removal of ascitic fluid.
