Flashes and floaters are common ocular complaints. Flashes refer to aberrations of light that are seen in a patient's field of gaze. The flashes can be of varying sizes, colors, frequency, and durations, depending on the cause. Floaters are another common visual phenomenon caused by particles or debris in the vitreous gel of the eye that cause shadows and thus visual changes, especially against bright backgrounds and in brightly lit environments. Flashes and floaters can occur individually or together. This article discusses common causes of flashes and floaters to help with the triaging and management of these patients.
闪光和飞蚊是常见的眼部症状。闪光是指患者注视区域中出现的光异常。根据病因不同,闪光的大小、颜色、频率和持续时间各异。飞蚊是另一种常见的视觉现象,由眼球玻璃体中的微粒或碎片引起,这些微粒或碎片会造成阴影,进而引起视觉变化,尤其是在明亮背景和光线充足的环境中。闪光和飞蚊可单独出现,也可同时出现。本文讨论闪光和飞蚊的常见病因,以协助对这些患者进行分诊和管理。
