间歇性外斜视的研究进展

间歇性外斜视是介于外隐斜与恒定性外斜视之间的一种斜视.起病较早,发病年龄通常为1岁到4岁.与其他类型的斜视不同,间歇性外斜视的儿童在很长一段时期内仍可维持正常眼位及双眼视功能,因此如何选择合适的干预时机及治疗方式对临床医师是个挑战.本文旨在回顾近年来间歇性外斜视的最新研究进展,重点对间歇性外斜视的严重度分级、非手术治疗方式、手术时机及手术方式、过矫及欠矫处理等方面的研究进展进行简要介绍,为间歇性外斜视的治疗提出改善化建议.

The progress of intermittent exotropia

Intermittent exotropia is a type of strabismus between exophoria and constant exotropia.The onset age is usually one to four years old.Different from other types of strabismus,intermittent exotropia patient can maintain normal binocular vision in a long period of time.So how to choose the optimal timing and effective treatment is a challenge for clinicians.The objective of this article is to review the recent research progress of intermittent exotropia,including the severity classification,non-surgical treatment,timing of surgery and surgical methods,overcorrection and undercorrection treatment etc.,and give some recommendations for the treatment of intermittent exotropia.
