A 71-year-old woman presented a non-arteritic anterior ischemic optic neuropathy in an optic nerve with previously registered superonasal peripapillary myelinated nerve fibers. Her past medical history was significant for controlled systemic hypertension, hyperlipidemia, and diabetes mellitus. The physiologic cup was absent in both optic discs. Non-arteritic anterior ischemic optic neuropathy mainly affected the temporal and inferior sectors of the peripapillary retinal nerve fiber layer, as could be demonstrated by retinal nerve fiber layer optical coherence tomography and optic disc optical coherence tomography angiography. Unlike other published reports, just a slight regression of the myelinated nerve fibers was observed after 1 year of follow-up. This occurred because ischemia mainly affected the temporal and inferior peripapillary sectors, whereas myelinated nerve fibers were superonasal to the optic disc.
一位 71 岁女性出现非动脉炎性前部缺血性视神经病变，受累视神经伴有先前记录的超鼻上象限神经纤维髓鞘化。她的既往病史包括控制不佳的系统性高血压、高血脂和糖尿病。两个视盘的生理杯均不存在。非动脉炎性前部缺血性视神经病变主要影响视盘周围视网膜神经纤维层的颞侧和下方部分，这可以通过视网膜神经纤维层光学相干断层扫描和视盘光学相干断层扫描血管造影来证实。与其他已发表的报告不同，在随访 1 年后仅观察到髓鞘化神经纤维略有退缩。这是因为缺血主要影响视盘周围的颞侧和下方部分，而髓鞘化神经纤维位于视盘的超鼻上象限。
