Varix of the vortex vein ampulla.
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.
