Abstract：
Isolated paresis of the inferior rectus muscle (IRM) represents a rare occurrence. This case report involves a young adult male who, abruptly during a Valsalva maneuver, encountered acute vertical diplopia due to right IRM paresis, resolving spontaneously within a few hours. The patient presented without identifiable risk factors, and magnetic resonance imaging revealed a minor left thalamic ischemic lesion. A cardiac study identified the presence of a patent foramen ovale, potentially associated with a paradoxical embolism, indicating its likely role in this transient ischemic event.
摘要：
下直肌（IRM）的孤立性麻痹很少发生。这个病例报告涉及一个年轻的成年男性,在瓦尔萨尔瓦演习中突然，由于右IRM轻瘫而遇到急性垂直复视，在几个小时内自发解决。患者出现没有可识别的危险因素，磁共振成像显示有轻微的左丘脑缺血性病变。一项心脏研究确定了卵圆孔未闭的存在，可能与矛盾的栓塞有关，表明其在这种短暂性缺血事件中的可能作用。
