[Color Doppler imaging of persistent heperplastic primary vitreous].
OBJECTIVE
To evaluate Color Doppler Imaging (CDI) in the value of Persistent Hyperplastic Primary Vitreous(PHPV).


METHODS
3 cases (4 eyes) of PHPV were reproted and were examinated by high resolution CDI, the blood flow pattern was evaluated in basic of two dimensional grayscale image.


RESULTS
CDI shows a band vascular structure coursing through the band-shaped moderately echogenic structure in the central portion of vitreous chamber, with the apex located near the optic disk and the base extending toward the lens. Spectral display of the Doppler signal indicated arterial flow.


CONCLUSIONS
Central vessel exhibiting arterial flow is compatible with a prominent persistent hyaloid vascular structure. This CDI imaging feature, in addition to microphthalmia and lack of calcification, is virtually pathogenomonic of PHPV and aids in enabling distinction between PHPV and simulating lesions.
