DYNAMIC ECHOGRAPHY OF VARIX OF THE VORTEX VEIN AMPULLA.

PURPOSE: To describe four cases of varix of the vortex vein ampulla imaged with dynamic echography.

METHODS: Observational case series of four patients with varix of the vortex vein ampulla diagnosed with ocular examination maneuvers such as digital pressure or Valsalva. Dynamic echography was used to confirm the diagnosis.

RESULTS: Dynamic echography can quickly and noninvasively show the varix of the vortex vein ampulla disappear with external pressure, or engorge with a Valsalva maneuver or altered gaze directions.

CONCLUSION: Dynamic echography is very helpful in the establishment of the diagnosis of varix of the vortex vein ampulla and differentiating this benign condition from other retinal or choroidal abnormalities.
