背景获得性非调节性内斜视是指在6个月大的儿童中突然出现持续性的共同性斜视。病例报告我们报道了一例20个月大的受试者在参加伯克利婴儿生物测量学研究时发生的获得性非调节性内斜视，这是一项关于3个月至3岁婴儿正视化和眼成分发育的纵向研究。在斜视发生前，这名儿童的眼部组件在屈光不正、角膜屈光度、晶状体半径、晶状体屈光度和眼轴尺寸方面都是正常的(在正交性研究参与者的平均值的2 SD以内)。屈光参差术后远视明显增加，晶状体屈光度明显低于平均水平，分别为+2.38D和37.2D。结论急性发作性内斜视患者眼部参数缺乏异常与其发病原因一致。此病例提示眼部分值对于评估获得性非调节性内斜视的风险可能没有用处。
Background Acquired nonaccommodative esotropia describes the sudden onset of a constant, comitant strabismus of idiopathic origin in children> 6 months of age.Case Report We present a case of acquired nonaccommodative esotropia at 20 months of age in a subject participating in the Berkeley Infant Biometry Study, a longitudinal study of emmetropization and ocular component development in infants between 3 months and 3 years of age. Ocular components for this child were normal before the onset of strabismus (within 2 SD’s of the mean for orthotropic study participants) for refractive error, corneal power, lens radii, lens power, and ocular axial dimensions. Refractive error postsurgically was significantly more hyperopic and crystalline lens power lower than average at+ 2.38 D and 37.2 D, respectively.Conclusions The lack of abnormal ocular parameters is consistent with the idiopathic etiology of acute onset esotropia. This case suggests that ocular component values may not be useful for assessing the risk of acquired nonaccommodative esotropia.
