Diplopia, or double vision, is the separation of images vertically, horizontally, or obliquely and can be described as monocular or binocular in origin. This condition can be due to either ocular misalignment, which disappears when either eye is occluded, or to an optical problem termed monocular diplopia, which does not disappear with monocular viewing. Binocular diplopia is usually caused by ocular misalignment or strabismus that can be detected using simple clinical tests. Patients with ocular misalignment should be assessed systematically and thoroughly to uncover all potentially serious cases. All patients with diplopia of acute onset should be investigated immediately. Those with a headache or pupillary involvement must be referred for same-day urgent imaging. In most cases, diplopia secondary to microvascular causes often resolves spontaneously within 6 months.
复视，即重影，是指图像在垂直、水平或斜向上分离，可分为单眼性或双眼性。这种情况可能是由于眼位不正（单眼遮盖时消失），也可能是由于一种称为单眼复视的光学问题（单眼观察时不消失）。双眼复视通常由眼位不正或斜视引起，可通过简单的临床检查发现。眼位不正的患者应进行系统全面的评估，以发现所有潜在的严重病例。所有急性起病的复视患者都应立即进行检查。伴有头痛或瞳孔受累的患者必须当天转诊进行紧急影像学检查。在大多数情况下，微血管病因导致的复视通常会在6个月内自行缓解。
