ZEISS INTRAOPERATIVE FLUORESCENCE IMAGING
Fluorescence is the property of atoms and molecules, so called fluorophores, to absorb light at a particular wavelength and to subsequently emit light of longer wavelength. Fluorescence microscopy can be based on autofluorescence or the addition of fluorescent dyes.1,2 Under normal light fluorescent dyes might be invisible. But a surgical microscope with integrated fluorescence technology lights up the dye to visualize tumor tissue or blood vessels during surgery.
TUMOR – VASCULAR – RECONSTRUCTIVE
The first use of intraoperative fluorescence imaging in surgery dates back to 1948 when surgeons used intravenous fluoresce in to enhance intracranial neoplasms during neurosurgery. Since then, additional fluorescent agents have been used for a variety of surgical applications. Intraoperative fluorescence imaging offers the benefits of high contrast and sensitivity, absence of ionizing radiation, ease of use, safety, and high specificity.Compared with standard unaided vision using white light imaging, real-time fluorescence imaging is helpful in visualizing cancerous tissue and delineating tumor margins. Moreover, improved visualization of the cancer can reduce damage to important normal structures such as nerves, blood vessels, ureters, and bile ducts. In challenging microsurgery, surgical visualization adjuncts are essential for making the right decisions at the right time.

INTRAOPERATIVE FLUORESCENCE IMAGING
Fully integrated in ZEISS neurosurgical microscopes and visualization systems, ZEISS INFRARED 800 enables intraoperative visual assessment of blood flow and vessel patency during arteriovenous malformation (AVM), bypass, aneurysm and anastomosis surgery.
Utilizing the video data from ZEISS INFRARED 800, FLOW® 800 from ZEISS is a unique analysis tool generating blood flow dynamics data by identifying detailed vessel blood flow intraoperatively – providing objective access to speed and sequence of blood flow.
Supporting intraoperative differentiation between diseased and healthy tissue, ZEISS BLUE 400 is the first fully microscope-integrated fluorescence module advancing surgical visualization to new dimensions.
Visualizes fluorescent dyes in the wavelength range from 540 to 690 nm for additional fields of applications. ZEISS YELLOW 560 highlights the fluorescence-stained structures while viewing non-stained tissue in natural-like color.
