间歇性外斜视手术时机及术后目标眼位之我见

间歇性外斜视的儿童在一段时期内可维持正常眼位及双眼视功能,但是病程多呈进行性,随病程发展可以不同程度影响双眼视功能.一方面,术后眼位有不同程度回退的可能,存在一定的欠矫或复发的发生几率;另一方面,术后眼位过矫正继发内斜视者有增加趋势.这些给临床医生决定手术时机以及设计手术目标眼位带来一定困惑:儿童间歇性外斜视究竟是早做还是推迟做手术?术后眼位是过矫正好还是欠矫正好?临床存在不同见解甚至误解.本文结合临床实际及国内外研究现状,围绕上述问题展开讨论,以期引起关注与讨论.

The operation time and post-operative target eye alignment of intermittent exotropia

Different from other types of strabismus,children with intermittent exotropia can maintain normal eye alignment and binocular vision in a long period of time.But the course of intermittent exotropia is mostly progressive,the eye position may drift outward even after surgery,so there is a certain risk of recurrence or undercorrection.These features often lead confusion to the clinicians in determining the operation time and postoperative target eye position.So how to choose the appropriate intervention time and target eye aligment is a challenge for clinicians.In this paper,we will combine the research status and clinical practice,discuss these issues,and present some point of view for the peer reference.
