Floaters are a common presenting ophthalmic symptom that may accompany sight-threatening disorders. In most cases, they are often secondary to benign, degenerative changes in the vitreous. In this review, we briefly examine the anatomy of the vitreous and describe how degenerative vitreous change contributes to the development of floaters. The causality of floaters in the presence and absence of a posterior vitreous detachment is reviewed, as is the clinical significance of these symptoms and signs in relation to their predictive value for determining the presence of sight-threatening retinal tears and/or detachment. Finally, a brief review of management options for debilitating floaters is presented.
飞蚊症是一种常见的眼科症状,可能伴随有威胁视力的疾病。在大多数情况下,它们通常继发于玻璃体的良性退行性改变。在本综述中,我们简要研究玻璃体的解剖结构,并描述退行性玻璃体变化如何导致飞蚊症的形成。我们回顾了存在和不存在玻璃体后脱离时飞蚊症的因果关系,以及这些症状和体征在预测威胁视力的视网膜裂孔和/或脱离方面的临床意义。最后,简要介绍了针对严重飞蚊症的治疗选择。
