With the rapid development of mini-invasive endoscopic techniques,in recent years many ophthalmic endoscopic surgeries such as endoscopic transnasal optic canal decompression and endoscopic transethmeid orbital decompression have been developed and extensively used in clinics.Good results have been achieved and many new findings have been exploited for physiopathology and treatment of a variety of optic nerve diseases,orbital diseases and lacrimal disorders.However,along with its increasingly extensive application,many problems have arisen due to relatively poor surgical conditions and equipment at the medical institutes,performance of surgery without experience and training in ophthalmic endoscopic techniques,improper surgical indications and the lack of an objective system for evaluating surgical outcomes.Therefore,it is necessary and important to establish strict and regular training programs,to develop a guide for regular diagnosis and treatment,and to carry out basic and clinical research for the systematic and precise development of this advanced technique.
