Orbital vascular anatomy

A thorough knowledge of the vascular anatomy in the orbit and periorbital tissues is critical for understanding alterations due to disease as well as avoiding these vessels during surgery in and around the orbit. The complexity and interindividual variability of the vessel anatomy is quite significant. Understanding the possible differences between the vascular patterns within individual patient orbits is particularly important for ensuring maximum preservation of blood supply and limiting bleeding within the orbit during surgical procedures. In addition, it allows for better treatment of vascular-related abnormalities that affect the globe and orbit.
