Two adult diabetic patients with chronic asymptomatic optic neuropathy attributed to an ischemic etiology are reported. In one case the typical syndrome of ischemic optic neuropathy occurred in one eye, while the fellow eye had asymptomatic hyperemic optic disc edema that persisted for 6 months without optic atrophy. A minor visual field defect initially detected in that eye resolved spontaneously in 1 month. In the second case, a recent onset, middle-aged diabetic developed bilateral optic neuropathy and optic disc edema that persisted for 12 months, with minimal signs of visual dysfunction. Axoplasmic transport blockage from low-grade ischemia to the optic nerve may cause acute or chronic optic disc edema with minimal or no visual symptoms.
报告了两名成年糖尿病患者，其慢性无症状性视神经病变归因于缺血性病因。在一例中，一只眼睛发生了典型的缺血性视神经病变综合征，而另一只眼睛有无症状性充血性视盘水肿，持续6个月且无视神经萎缩。最初在该眼中检测到的轻微视野缺损在1个月内自发消退。在第二例中，一名近期发病的中年糖尿病患者出现双侧视神经病变和视盘水肿，持续12个月，视觉功能障碍迹象轻微。低度缺血导致的轴浆运输阻滞至视神经可能会引起急性或慢性视盘水肿，伴有轻微或无视觉症状。
