An Ultrafast Ultrasound Microvessel Imaging Technique for Assessing Patients with Unilateral Papilledema

Objective: The purpose of this study was to develop an ultrafast ultrasound microvessel imaging technique for assessing patients with unilateral papilledema or choroidal folds. Methods: Two patients with unilateral papilledema were enrolled in this study. An ultrasound probe was used to evaluate the hemodynamic properties in the eye structures noninvasively. Results: For patients with unilateral papilledema, the magnitudes of blood volume of the optic disc are statistically lower in the eye with papilledema than a normal eye. Conclusion: significant differences in power Doppler intensity were found between the eye with papilledema and control eye for patients with unilateral papilledema. Significance: Ultrafast ultrasound microvessel imaging provides a noninvasive technique to measure the hemodynamic properties of the optic disc, which is useful for assessing patients with unilateral papilledema.
