Varix of the vortex vein ampulla is a bulging of the vein and overlying retina into the vitreous. It is of uncertain etiology. The lesion is lightly pigmented and ranges in size from one to three disc diameters. It has a dynamic nature and can be flattened by applying pressure to the globe. Viewing the varix is greatly enhanced with red-free light. Three cases are presented as incidental findings during routine examination, and one as a referral. Varices are a benign condition requiring no treatment.
涡静脉壶腹静脉曲张是静脉及其上方视网膜向玻璃体的膨出。其病因不明。病变色素较淡，大小从1到3个视盘直径不等。它具有动态特性，通过对眼球施加压力可使其变平。用无赤光观察静脉曲张可大大增强效果。3例是在常规检查中偶然发现的，1例是转诊病例。静脉曲张是一种良性疾病，无需治疗。
