Vertical strabismus can be associated with paretic or restrictive causes. Paretic causes may be due to a weak muscle or paresis, or to a total lack of muscle function caused by a third, fourth or sixth cranial nerve palsy. When examining a patient with vertical strabismus, it is paramount that we differentiate between a restricted cause and paretic cause. This paper discusses the nonsurgical techniques used in evaluating paretic vertical strabismus. There are no easy methods, and evaluation techniques can vary depending on the cooperation of the patient. It is essential to look at versions and ductions, pattern strabismus, measure in all positions of gaze and evaluate torsion. We know that measuring strabismus, especially in children can be challenging. Afew different tests and techniques are discussed. A review of the literature regarding the different evaluation techniques for vertical strabismus were collated and analyzed.
垂直性斜视可能与麻痹性或限制性病因相关。麻痹性病因可能是由于肌肉无力或麻痹,或者是由第三、第四或第六脑神经麻痹导致的肌肉功能完全丧失。在检查垂直性斜视患者时,区分限制性病因和麻痹性病因至关重要。本文讨论了用于评估麻痹性垂直性斜视的非手术技术。没有简单的方法,评估技术可能因患者的配合情况而异。观察眼球的运动和转位、斜视模式、在所有注视位置进行测量并评估眼球扭转情况非常重要。我们知道,测量斜视,尤其是在儿童中,可能具有挑战性。本文讨论了一些不同的测试和技术。对有关垂直性斜视不同评估技术的文献进行了整理和分析。
