  • Publication number: 20100305514
    Abstract: An ophthalmic injection system having coaxial cannulae includes a plurality of syringe bodies and a plurality of cannulae, wherein a first non-flexible cannula is configured to accommodate and guide a second cannula that moves inside the first cannula and penetrates into the internal cavity of an eye globe. The first cannula is long enough to penetrate one or more outer layers of the eye globe. A syringe body is connected to the second cannula for accommodation and infusion of a pharmaceutical composition. A plunger is inserted into an annular space of the second syringe body at its distal end for injecting the pharmaceutical composition to the surgical site.

  • Publication number: 20080125377
    Abstract: Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are formulations which deliver a variety of therapeutic agents, including but not limited to BOL-303213-X, to a subject for an extended period of time. The formulation may be placed in an aqueous medium of a subject, including but not limited to via intraocular or periocular administration, or placement proximate to a site of a disease or condition to be treated in a subject. A method may be used to administer BOL-303213-X to treat or prevent angiogenesis, choroidal neovascularization, or age-related macular degeneration, or wet age-related macular degeneration in a subject. The formulations may comprise BOL-303213-X or other therapeutic agents.
