Varix of the vortex vein ampulla: A small case series

PURPOSE. To report three cases of varix of the vortex vein ampulla. METHODS. Observational small case series. During 2002, three patients were examined for suspected choroidal melanoma. In all cases, the lesions were located at the equator or the periphery. RESULTS. The lesions became more prominent when the eyes were positioned in the direction of the lesion, and disappeared when firm pressure by ultrasound probe was applied on the globe, while the eye was in primary position, or fundus was examined with a three-mirror Goldmann contact lens. These dynamic characteristics were also demonstrated by color Doppler imaging. CONCLUSIONS. Varix of the vortex vein ampulla is an extremely rare condition. This diagnosis should be considered when an elevated choroidal lesion disappears when the fundus is examined with contact lens.
