Abstract: A dopplervelocimetria colorida é uma modalidade do exame ultra-sonográfico que se expandiu rapidamente em todas as áreas da medicina, em virtude da sua riqueza de informações. A dopplervelocimetria colorida das artérias orbitais tem sido empregada no auxílio diagnóstico de doenças oftalmológicas, bem como para o estudo de doenças específicas como a pré-eclâmpsia. O objetivo deste estudo é descrever a anatomia normal da região orbital e detalhar a técnica de exame dopplervelocimétrico colorido, tendo em vista s… Show more

“…), using Eccocee equipment (Toshiba Medical Systems Co, Ltd, Tokyo, Japan) with a 7.5-MHz linear transducer and a 50-Hz wall filter setting. 1,7,12,[14][15][16][17]21,22 Patients were examined in the supine position. Gel was applied to the closed eyelid, and the transducer was carefully placed on the eyelid to avoid creating pressure-derived artifacts.…”

“…The sample volume was adjusted to 2 to 3 mm and oriented nasally and superior to the optic nerve, just lateral to the visible hypoechoic stripe representing the nerve, nearly 12 to 15 mm of the posterior wall of the sclera (Figure 1). 1,7-9, [14][15][16]21 After insonation of the ophthalmic artery, the incidence angle was verified to ensure that insonation was performed with an angle of less then 20°. 7,12,[14][15][16][17]22 The flow velocity waveforms showed a steep maximum systolic peak with a dicrotic protodiastolic notch and a low diastolic flow velocity ( Figure 1).…”
