方法：频繁瞬目患儿73例，通过详细询问病史，进行视力、眼位、裂隙灯显微镜检、角膜荧光染色、泪膜破裂时间(BUT)检查、泪液分泌测定(Schirmer I试验)检查、眼底、对视力低下的儿童进行散瞳验光检查，并对每例患儿进行血清铅(Pb)、镉(Cd)、钙(Ca)、铁(Fe)、锌(Zn)、铜(Cu)、镁(Mg)7种微量元素进行测定。

结果：儿童频繁瞬目的发病原因主要有眼表及眼附属器疾患、不良生活习惯、泪膜的不稳定性、屈光异常、血清微量元素缺乏等。

结论：儿童频繁瞬目征是眼科常见病与多发病， 但容易被忽视，其病因较为复杂， 同一患者可能同时存在多种致病因素，正确的分析原因、选择有效的治疗方法，可明显缓解症状，提高临床治愈率。

METHODS: A series of examination were performed in 73 children with frequent eye blink. They were asked about history in detail, visual acuity, position of eye, slit-lamp microscope, fluorescent, tear film break-up time(BUT), Schirmer Ⅰ test, ocular funds, mydriasis optometry check on children under the vision, and the patients levels of serum lead(Pb), cadmium(Cd), calcium(Ca), iron(Fe), zine(Zn), copper(Cu), magnesium(Mg)7 trace elements were measured.

RESULTS: The cause of frequent instantaneous purpose of the 73 cases of children: the ocular surface and ocular adnexal disease, unhealthy living habits, stability of the tear film, ametropia, serum trace elements lack and so on.

CONCLUSION:Frequent eye blink in children is a common and frequently occurring disease, but it can be easily overlooked. Due to eye disease, physiology, medicine, environment and other factors affect, Its cause is more complex, multiple etiological factor simultaneous with one case. Correct analysis of the reasons for choosing an effective treatment can significantly relieve symptoms and improve the clinical cure rate.
