缺血性视神经症的障碍部位可分为前后两部,前部系由于营养视神经乳头的睫状后动脉循环障碍引起,而后部为视神经乳头以外神经营养血管障碍所致。巨细胞性动脉炎常发生本病,但在日本通过颞动脉活检确诊为动脉炎的病人并不多。如果单眼发病不及时治疗,则可累及另眼,继发失明,这种可能性也较高。如果血沉快,只要疑有动脉炎,不要等待活检结果,应及早给予大剂量肾上腺皮质激素。动脉缺血性视神经症早期应用上述疗法,效果较好,可恢复一定的视力。在欧美,动脉炎的发生率较高,活检即使阴性,也多给予治疗,但比较困难的是并非由巨细胞动脉炎所引起的非动脉炎性缺血性视神经症的治疗。此种类型发病率较高,目前尚无有效的治疗方法,多数试用肾上腺皮质激素疗法。如果不这样治疗,患者也只好坐待视力 The ischemic optic neurosis disorders can be divided into two parts before and after the front due to nutrition optic nerve papillary posterior ciliary artery circulation disorder caused by the back of the optic nerve head outside of the neurotrophic vascular disorders. Giant cell arteritis often occurs in this disease, but in Japan by temporal artery biopsy diagnosed as arteritis are not many patients. If the monocular disease is not treated in time, it may affect the other eye, secondary blindness, this possibility is higher. If ESR, as long as the suspected arteritis, do not wait for biopsy results, should be given large doses of adrenal cortex hormones. Arterial ischemic optic neuropathy early application of the above therapy, the effect is better, can restore some vision. In Europe and the United States, the higher the incidence of arteritis, biopsy even negative, but also give more treatment, but more difficult is not caused by giant cell arteritis non-arteritic ischemic optic neurosis treatment. This type of high incidence, there is no effective treatment, most trials of adrenal cortex hormone therapy. If not treated, patients also had to wait for sight
