To determine the prevalence and clinical characteristics of patients with Duane retraction syndrome presenting with exotropia in a tertiary eye care center.
Medical records of 140 patients with Duane retraction syndrome and exotropia (of the total 441 patients with Duane retraction syndrome) seen from 2000 to 2009 were reviewed. Characteristics studied included age at presentation, gender, laterality, manifest primary position, abnormal head posture, ocular motility, and overshoots. Data were collected regarding associated ocular or systemic abnormalities and amblyopia.
The mean age of the patients at presentation was 16.96 ± 15.09 years (range: 1 to 70 years). Of the 140 patients with Duane retraction syndrome and exotropia, 59 (42%) were male. Unilateral type I Duane retraction syndrome accounted for 118 (84.2%), type II for 7 (5%), and type III for 10 (7.1%) patients, whereas 5 (3.6%) had Duane retraction syndrome and bilateral exotropia. Duane retraction syndrome was seen in the left eye, right eye, and both eyes in 97 (69%), 37 (26%), and 6 (4%) patients, respectively. Exotropia ranged from 10 to 60 prism diopters. An abnormal head posture was noted in 101 (72%) and upshoot in 26 (18.6%) patients. Reported ocular and systemic abnormalities in these patients included cataract (6), aniridia (1), nasolacrimal duct block (1), and retinal breaks (1).
This is an exclusive study on a large series of patients with Duane retraction syndrome and exotropia. Almost one-third of patients with Duane retraction syndrome patients might have exotropia. Although patients with Duane retraction syndrome and exotropia had clinical characteristics and associations similar to those with Duane retraction syndrome and esotropia, there was an increased propensity for overshoots and face turn opposite to the affected eye, which the authors hypothesize to be due to a tight or short lateral rectus muscle.

确定在一家三级眼科护理中心就诊的表现为外斜视的杜安眼球后退综合征患者的患病率及临床特征。
回顾了2000年至2009年间诊治的140例杜安眼球后退综合征合并外斜视患者的病历（杜安眼球后退综合征患者总数为441例）。研究的特征包括就诊年龄、性别、眼别、显性原在位、异常头位、眼球运动及过冲。收集了相关眼部或全身异常及弱视的数据。
患者就诊时的平均年龄为16.96±15.09岁（范围：1至70岁）。在140例杜安眼球后退综合征合并外斜视患者中，59例（42%）为男性。单侧I型杜安眼球后退综合征占118例（84.2%），II型占7例（5%），III型占10例（7.1%），而5例（3.6%）患有杜安眼球后退综合征合并双侧外斜视。杜安眼球后退综合征分别见于97例（69%）患者的左眼、37例（26%）患者的右眼和6例（4%）患者的双眼。外斜视度数范围为10至60棱镜度。101例（72%）患者存在异常头位，26例（18.6%）患者存在过冲。这些患者报告的眼部和全身异常包括白内障（6例）、无虹膜（1例）、鼻泪管阻塞（1例）和视网膜裂孔（1例）。
这是一项关于大量杜安眼球后退综合征合并外斜视患者的专项研究。几乎三分之一的杜安眼球后退综合征患者可能有外斜视。虽然杜安眼球后退综合征合并外斜视患者的临床特征及合并症与杜安眼球后退综合征合并内斜视患者相似，但过冲及脸转向患眼对侧的倾向增加，作者推测这是由于外直肌紧张或短小所致。[《小儿眼科与斜视杂志》。2017；54(2)：117 - 122。]
