To identify and examine factors that affect postoperative binocularity in children diagnosed with acquired nonaccommodative esotropia (ANAET).
Retrospective chart review.
Thirty-four pediatric patients who received surgery for ANAET by 1 surgeon (I.M.) at the Ivey Eye Institute, University of Western Ontario (London, Ont.).
A multivariate logistic regression analysis was performed to evaluate the effect of the following factors on achieving stereopsis postoperatively: age at onset of esotropia (AO), duration of misalignment (DOM), presence of A/V pattern, recent intermittency of esotropia, and presence of dense amblyopia.
Forty-one percent of all patients achieved stereoacuity of 100 seconds of arc or better. AO was found to be the only factor significantly associated with postoperative stereopsis (adjusted odds ratio = 1.063, P<0.05). None of the children with AO who were younger than 30 months regained bifoveal fixation regardless of their DOM.
Age of onset appears to play a crucial role on postoperative functional outcome in children with ANAET. Delayed surgery in children with an age of onset beyond 30 months did not seem to be detrimental to regaining bifoveal fixation.
确定并研究影响后天性非调节性内斜视（ANAET）患儿术后双眼视的因素。
回顾性图表分析。
由 1 位外科医生（I.M.）在西安大略大学 Ivey 眼科研究所为 34 名患有 ANAET 的儿科患者进行手术。
采用多变量逻辑回归分析，评估以下因素对术后获得立体视的影响：斜视发病年龄（AO）、斜视持续时间（DOM）、A/V 模式、斜视近期间歇性、以及存在致密性弱视。
41%的患者获得了 100 秒或更好的立体视锐度。AO 是唯一与术后立体视显著相关的因素（调整后的优势比=1.063，P<0.05）。无论 DOM 如何，发病年龄小于 30 个月的儿童均未能恢复双眼注视。
发病年龄似乎对 ANAET 患儿术后功能结果起着至关重要的作用。发病年龄超过 30 个月的儿童延迟手术似乎不会对恢复双眼注视造成不利影响。
