216例频繁瞬目儿童屈光状态及病因分析

Clinical analysis of abnormal blinking in 216 children

目的 :分析儿童频繁瞬目病因并探索相应的治疗方法。方法 :收集 2 0 0 2年 4月～ 2 0 0 4年 4月频繁瞬目的 3～14岁儿童 2 16例 ,依据其发病过程、治疗经过、视力、眼位、结膜、角膜检查、屈光检查以及其他辅助检查等方面寻找病因 ,进而进行治疗及纠正。结果 :2 16例频繁瞬目儿童中各类屈光不正 16 1例 ,其中 86例视力基本正常 ,116例主诉有长时间屏幕注视史 ,仔细检查后发现 15例单眼屈光不正 ,14 6例双眼屈光不正 ,经相应治疗后 14 5例患儿异常瞬目症状逐步消失 ,5例有减轻表现 ,有效率达 93.17%。有眼表疾病的 4 0例 ,其中包括沙眼、慢性结膜炎、春季卡他性结膜炎、滤泡性结膜、结膜结石等结膜疾病共 2 4例 ,内翻倒睫、睑痉挛、麦粒肿、霰粒肿、睑缘炎等眼睑疾病 13例 ,浅层点状角膜炎 3例 ,经治疗后异常瞬目症逐渐消失达 10 0 %。另外发现 12例与神经系统疾患有关 ,其他原因 3眼。结论 :多种眼疾可导致瞬目增多 ,其中屈光异常和眼表疾病是小儿异常瞬目征的主要病因 ,平时不健康用眼是常见的诱因 ,细致认真的检查是做出正确诊断的关键。异常瞬目伴有“鬼脸”或运动增多应请神经内科协助治疗。

Objective:To investigate the pathogenesis and appropriate therapy in children with abnormal blinking.Methods:Two hundred sixteen children with abnormal blink reflex were studied from 2002.4～2004.4. Age ranged from 3 to 14 years. The pathogenesis was based on an examination of the cornea and conjunctiva and the status of visual acuity,refractive error and past treatment. They were then given appropriate therapy after a diagnosis was made.Results:One hundred sixty-one patients were found to have ametropia in at least one eye. Forty patients were found to have ocular surface disease including trachoma,keratitis,chronic conjunctivitis,vernal keratoconjunctivitis,hordeolum,chalazion,et al. A few cases had conditions related to neuropathy. Correction or therapy accordingly proved to be effective in solving the problems.Conclusion:Abnormal blink reflex in children can be caused by a variety of factors. The most common were ametropia and ocular surface disease. Early diagnosis,correction of ametropia and treatment of eye disease can be effective solutions for abnormal blinking in children.[
