一些作者报道用视神经鞘减压术治疗假性脑瘤及一些视神经、视网膜病变，取得了不同程度的效果。但对手术的机理缺乏统一的认识，也没有任何一种经得起推敲的理论，其临床效果也值得进一步的认真评价。具体到视神经鞘减压术对缺血性视神经病变是否有效，众说不一，机理不明。目前美国正对缺血性视神经病变减压治疗试验给予资助，但笔者认为，从对其预期结果的分析看，该试验并不能解决手术的所有问题，最终也不能明了手术的机理问题。视神经鞘减压术是一种尚应研究其适应证的手术，目前情况下，对各种视神经病变不加选择地实施这种新的并具危险性的手术是轻率的。
Some authors report that optic nerve sheath decompression for the treatment of pseudo-brain tumors and some optic neuropathy, retinopathy, and achieved varying degrees of effect. However, the lack of a unified understanding of the mechanism of surgery, there is no any kind of theory that can withstand scrutiny, and its clinical effect deserves further serious evaluation. Specific to the optic nerve sheath decompression of ischemic optic neuropathy is effective, different, the mechanism is unknown. At present, the United States is subsidizing ischemic optic neuropathy decompression test, but I believe that from the analysis of its expected results, the test does not solve all the problems of surgery, and ultimately can not understand the mechanism of surgery. Optic nerve sheath decompression is a surgery that should be studied for indications. In the present case, the indiscriminate implementation of such new and dangerous surgery for various optic neuropathy is frivolous.
