週期性內斜視―病例報告

Cyclic Esotropia-A Case Report

摘要


週期性斜視(cyclic strabismus)是一種極為罕見的斜視,據文獻報告每3000到5000個斜視病人中才可發現一例,從1958年第一個病例被提出後,至今只有50例被報告過。週期性斜視中又以週期性內斜視(cyclic esotropia)占絕大多數,其特點在於病人的內斜視會以一定的週期出現、消失。這種規律性與病人視力、調節力、疲勞等無關。在週期性內斜視中其週期以48小時為最常見。本篇即報告一例以48小時週期的週期性內斜視病例,經手術治療後症狀完全改善、癒後良好。

Cyclic strabismus is a very rare form of strabismus. Its incidence is reported to be about one per 3000 to 5000 strabismic patients. About 50 cases have been reported since the first description in 1958. Cyclic esotropia is the most common form of cyclic strabismus. It is characterized by regular recurring esotropia usually in an alternate day fasion which is unrelated to visual acuity, accommodation fatigue or nonfusion. The 48-hour cycle is the most common among the cycle of cyclic strabismus. The paper is reported that a 48-hour cycle cyclic estropia had good prognosis after treatment.
