Patients with acute optic neuritis typically present with acute loss of vision. We describe a case of a young lady of 25 years of age with blurring of vision in the upper visual field of the right eye with otherwise intact visual acuity as the only presenting symptom. Although altitudinal visual field defect is not unknown to be associated with acute optic neuritis, it is generally considered a relatively uncommon occurrence. Our case illustrates an unusually unique occurrence of upper altitudinal visual field defect in association with unaffected visual acuity as the sole presenting symptom of acute idiopathic unilateral optic neuritis. When an altitudinal visual field defect is a presenting feature, besides the usual vascular and compressive causes, optic neuritis should be remembered in the list of differential diagnoses.
急性视神经炎患者通常表现为急性视力丧失。我们描述了一例25岁年轻女性病例，其右眼上半视野视力模糊，而其他视力正常，这是唯一的就诊症状。虽然高度性视野缺损与急性视神经炎有关并非不为人知，但一般认为这是相对不常见的情况。我们的病例说明了一种异常独特的情况，即高度性上半视野缺损与视力未受影响相关，作为急性特发性单侧视神经炎的唯一就诊症状。当高度性视野缺损是一个就诊特征时，除了常见的血管性和压迫性病因外，视神经炎应列入鉴别诊断清单中。
