非动脉炎性缺血性视神经病变导致视力轻度到明显下降且发生于老年人。常发生无痛性的视功能损害,瞳孔传入神经受损和视盘水肿。很多病人视力的损害是迅速和持续的。然而在少数病人中大概4％～30％视力丧失可能在六周以内,随后视力自发改善是罕见的。近年来提倡采用视神经鞘减压术治疗进行性非动脉炎性块血性视神经病变,这些治疗效果引起了很多争论。我们治疗了四例病人(五只眼)他们是进行性非动脉炎性缺血性视神经病变,采用了视神经鞘减压术。其中有四只眼视力提高和视野扩大,一只非进行性的眼视力全部丧失。表明手术后没有明显改善。我们的结果证实了以前的发现。视神经鞘减压改善了进行性非动脉炎性缺血性视神经病变所致的视力损害,此症在以前没有成功的治疗。
Non-arteritic ischemic optic neuropathy leads to mild to significant visual decline and occurs in the elderly. Pain often occurs as a visual impairment, pupil afferent nerve damage and optic disc edema. Many patients suffer from rapid and persistent vision loss. However, in a small number of patients about 4% to 30% loss of vision may be less than six weeks, followed by spontaneous improvement in vision is rare. In recent years, the promotion of the use of optic nerve sheath decompression for the treatment of progressive non-arteritic block optic neuropathy, these therapeutic effects caused a lot of controversy. We treated four patients (five eyes) who underwent progressive non-arteritic ischemic optic neuropathy with optic nerve sheath decompression. Among them, four eyes improved visual acuity and vision, a non-progressive loss of all visual acuity. No significant improvement after surgery. Our results confirm the previous findings. Optic nerve sheath decompression improves visual impairment caused by progressive non-arteritic ischemic optic neuropathy, which has not previously been successfully treated.
