Diplopia or double vision is the separation of images vertically, horizontally or obliquely and can be monocular or binocular in origin. Binocular diplopia is most commonly caused by ocular misalignment or strabismus that can be detected using simple clinical tests. All patients with diplopia of acute onset should be investigated urgently and those with a headache or pupillary involvement need to be referred for same-day urgent imaging. Diplopia secondary to microvascular causes on the other hand often spontaneously resolves within six months.
复视或重影是指图像垂直、水平或倾斜分离，可源于单眼或双眼。双眼复视最常见于眼位不正或斜视，可通过简单的临床检查发现。所有急性发作的复视患者均应紧急检查，伴有头痛或瞳孔受累的患者需要进行当天的紧急影像学检查。另一方面，由微血管原因引起的复视通常在六个月内自行消退。
