Abstract
Featured is a device for puncturing tissue of a body, such as the lamina cribosa and methods for treating a CVRO with such a puncturing device. The puncturing device includes a puncture member being generally configured and arranged to locally disrupt tissue proximal an area of the puncture site, to minimize the potential for damage to body parts or tissue immediately adjacent to this area of the puncture site and to facilitate perforation of the tissue at the puncture site. When the lamina cribosa is being punctured, the puncture member is more particularly configured and arranged to locally disrupt connective tissue of the lamina cribosa proximal to and surrounding the central retinal vein while minimizing the potential for structural damage to the central retinal vein. In an exemplary embodiment, the lamina cribosa is repeatedly punctured to strip/locally disrupt connective tissue surrounding the central retinal vein.
