Objective To observe the functional state of the optic nerve and discover the injury of visual pathway function in time under general anesthesia. The flash visual evoked potential ( F-VEP) was used to monitor visual function during orbital surgery. 目的为了了解眼眶手术中视神经的功能状态,及时发现全麻手术中视功能的损伤情况,采用闪光视觉诱发电位(flashvisualevokedpotential,F-VEP)进行术中视功能监护。
Conclusion F-VEP is an abstract Objective and effective method of showing optic nerve function, but the anesthetic agents and depth of anesthesia will affect it. 结论FVEP是客观反映视神经功能的简便有效的方法,但麻醉药及麻醉深浅度均对FVEP有影响。
