Saccadic intrusions are small involuntary saccadic movements that disrupt visual fixation. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. The saccade amplitude can occasionally be very small, which is referred to as ocular microflutter. The authors present a patient with acute-onset oscillopsia following a non-specific viral condition. An ocular microflutter was subsequently detected using video-oculography. After extensive investigation, a diagnosis of isolated idiopathic or post-viral ocular microflutter was made. The evolution of the condition was favourable, and the progressive improvement of oscillopsia occurred during the following months; however, complete resolution was not achieved. Ocular microflutter is a saccadic intrusion that is rarely described in the literature and is likely go clinically unnoticed because of its small amplitude and the rare use of video-oculography in daily practice. In patients in whom this condition is suspected, the use of video-oculography is essential for a correct diagnosis.
扫视侵入是一种小的非自主性扫视运动，会干扰视觉注视。在没有扫视间隔的扫视侵入中，眼球扑动和眼阵挛较为突出。扫视幅度偶尔可能非常小，这被称为眼球微扑动。作者报告了一名在非特异性病毒感染后出现急性发作性视振荡的患者。随后通过视频眼震图检测到眼球微扑动。经过广泛检查，诊断为孤立性特发性或病毒感染后眼球微扑动。病情演变良好，视振荡在接下来的几个月中逐渐改善；然而，并未完全缓解。眼球微扑动是一种扫视侵入，在文献中很少被描述，并且由于其幅度小以及日常实践中很少使用视频眼震图，可能在临床上未被注意到。对于疑似患有这种疾病的患者，使用视频眼震图对于正确诊断至关重要。
