We examined in collection of 66 patients (116 eyes) vena orbitalis superior (VOS) by Colour Doppler flow imaging (CDFI). In 20% was VOS wider than 3.5 mm in patients without subjective problems and without an orbitopathy, with maximum of width 4.9 mm. In patients with retrobulbar pressure, pain, without orbitopathy was dilatation above 3.5 mm in 31% cases, with maximum 5.4 mm. In patients with orbitopathy was dilatation VOS above 3.5 mm already in 85%, with maximum 7.1 mm. We averaged considerable variability of width in examined VOS.
