Limitations of color Doppler sonography in the imaging of ocular vessels.

چکیده
PURPOSE To describe a case where detection of blood flow in the central retinal artery and the central retinal vein was limited by an artifact evoked by the optic disc drusen. METHODS Case report. RESULTS During color Doppler sonography, examination of optic disc drusen may generate an artifact--the so-called twinkling artifact--which can simulate blood flow and make evaluation of the central retinal vessels impossible. CONCLUSIONS Twinkling artifact does not allow evaluation of color Doppler sonography in the imaging of ocular vessels.
