Abstract：Objective To explore the morphological structure of each Check ligament of the eye,the relationship with the surrounding anatomical structure,and the physiological function,and to lay the foundation for the improvement and promotion of the clinical application of this operation.Methods Anatomical study was made of ten Chinese adult cadaver specimens (7 formaldehyde fixation,3 fresh).Seven pairs (14 orbits) were anatomized in vitro,three pairs (6 orbits) were prepared by histological section.Immunohistochemical study was carried out in key areas.Results Gross anatomy showed that the fornix Check ligament between the upper eyelid muscle and rectus superior extended from both sides to the inner and outer canthus.The fornix Check ligament was linked with each Check ligament of the internal and external rectus and fixed on the orbital wall.The ligament structure continues to extend to the lower part of the eyeball,as far as the inferior obhque muscle and the inferior rectus.This ligament forms a circular fascia system around the eye,along with some smooth muscle cells found in this area.Conclusion This annular fascia structure wrapped around the eye is called the "Extraocular Check Ligament System".This system plays an important role in maintaining the position of the conjunctiva fomix and the eyeball,and coordinates with the physiological movement of the eyeball and eyehds and other functions.This study aids in a better understanding of the surgical principles of blepharoptosis correction with upper fomix Check ligament suspension,providing a reference for its chnical application.
