We reviewed 281 consecutive patients with sensory esotropia or exotropia to determine the prevalence of dissociated vertical deviation in patients with sensory strabismus.
We reviewed the charts of all patients who received a diagnosis of sensory heterotropia or dissociated vertical deviation and who were examined at the Pediatric Ophthalmology Service at the Texas Children's Hospital between 1973 and 1992. Statistical analyses of the prevalence of dissociated vertical deviation were determined after evaluating the direction of the accompanying horizontal strabismus and examining the temporal relationship of the unilateral vision loss.
Dissociated vertical deviation was diagnosed in 35 patients (12.5%). It occurred more frequently in sensory esotropia (22 patients, 18.3%) than exotropia (13 patients, 8.1%) (P = .009). The age at which unilateral visual loss occurred did not influence the development of dissociated vertical deviation.
Dissociated vertical deviation in patients with acquired loss of vision does not support the contention that dissociated vertical deviation is a genetically predetermined anomaly of binocular vision.
我们回顾了连续281例感觉性内斜视或外斜视患者，以确定感觉性斜视患者中分离性垂直偏斜的患病率。
我们回顾了1973年至1992年间在德克萨斯儿童医院小儿眼科接受感觉性斜视或分离性垂直偏斜诊断并接受检查的所有患者的病历。在评估伴随水平斜视的方向并检查单眼视力丧失的时间关系后，确定分离性垂直偏斜患病率的统计分析。
35例患者（12.5%）被诊断为分离性垂直偏斜。它在感觉性内斜视（22例，18.3%）中比外斜视（13例，8.1%）更常见（P = 0.009）。单眼视力丧失发生的年龄不影响分离性垂直偏斜的发展。
后天性视力丧失患者的分离性垂直偏斜不支持分离性垂直偏斜是双眼视觉的遗传预定异常这一观点。
