Indication
ZYOGREEN is an optical imaging agent indicated for: Fluorescence imaging of vessels (micro- and macro-vasculature), blood flow and tissue perfusion before, during and after vascular, gastrointestinal, organ transplant, plastic, micro- and reconstructive surgeries, including general minimally invasive surgical procedures, in adults and pediatric patients Fluorescence imaging of extrahepatic biliary ducts in adults and pediatric patients from birth to less than 1 year of age and 6 years of age and older Fluorescence imaging of lymph nodes and lymphatic vessels during lymphatic mapping in adults with cervical and uterine cancer Ophthalmic angiography in adults and pediatric patients.
ZYOGREEN is contraindicated in patients with a history of hypersensitivity to indocyanine green. Reactions have included anaphylaxis.

Available Forms
2.5 mg, 25 mg single-dose ampules, 10 mL single-dose ampules

Mechanism of Action
When bound to proteins in plasma or in lymph fluid, indocyanine green absorbs light in the near-infrared region with peak absorption at 805 nm and emits fluorescence (light) at a slightly longer wavelength, with peak emission at 830 nm. Fluorescence imaging devices provide external energy as near infrared light for indocyanine green to absorb, resulting in excitation of the indocyanine green, and the emitted light (fluorescence) is transferred from the field of view to an image on a monitor.
