飞蚊症是玻璃体混浊物引起的内视现象，也有学者将其术语描述为“有症状的玻璃体混浊”，临床上常指原发性。随着全球近视发病率的升高和老龄化的加剧，玻璃体飞蚊症在临床上越来越常见却又较少受到关注。飞蚊症引起的烦恼和困扰可以影响患者的视觉及生活质量； 少数患者难以忍受并有强烈的治疗愿望。近年来，YAG激光消融术治疗飞蚊症颇受关注，尽管部分医生对其有效性和安全性仍存有顾虑，但近年的多项研究报道对此技术持积极态度，我们在近几年的临床实践中也积累了一些经验。本篇综述介绍了飞蚊症的病因和分类，重点介绍YAG激光消融治疗的临床适应证、操作要点和安全性。

Floaters are entopic phenomenon created by vitreous opacities. Some researchers term it as “symptomatic vitreous turbidity”, which usually refers to primary type in clinic. With the increasing prevalence and aging of myopia worldwide, vitreous floaters are becoming increasingly prevalent in clinics but receiving less attention. Floaters can impair patients' vision and quality of life due to their discomfort and disorientation. A few patients become intolerable and express a strong desire for treatment. YAG laser vitreolysis for floaters has garnered considerable attention in recent years. Although some doctors still have concerns about its efficacy and safety, a handful of studies have found some beneficial effects in recent years. The author has gained expertise in clinical practice in recent years. In this review, we talk about what causes floaters and how to classify them. We also talk about the clinical indications, how YAG laser ablation works, and whether or not it is safe.
