In five patients, extreme gaze resulted in the appearance and expansion of a lesion located at the site of a venous vortex ampulla. The dimensions and color of the lesion varied depending upon the direction and duration of gaze. The lesion expanded when the head was positioned below the level of the heart and when a Valsalva maneuver was performed, even when the primary position of gaze was maintained. The lesion rapidly detumesced and disappeared when the head was elevated, digital pressure was exerted on the globe, or gaze was directed elsewhere. Fluorescein angiography confirmed that this tumefaction originated from the venous vortex ampulla. These dynamic features observed ophthalmoscopically and demonstrated by ultrasonography are characteristic of the vortex ampulla varix; the lesion should not be confused with a malignancy.
在5例患者中，极度凝视导致位于静脉涡静脉壶腹部位的病变出现并扩大。病变的大小和颜色因凝视方向和持续时间而异。当头部位于心脏水平以下以及进行瓦尔萨尔瓦动作时，即使保持初始凝视位置，病变也会扩大。当头部抬高、对眼球施加指压或凝视方向转向其他地方时，病变迅速消肿并消失。荧光素血管造影证实这种肿胀起源于静脉涡静脉壶腹。这些通过检眼镜观察到并经超声检查证实的动态特征是涡静脉壶腹静脉曲张的特征；该病变不应与恶性肿瘤相混淆。
