Detection of Occult Arteriovenous Malformation With Annular Array Ultrasonography.

Retinal vascular tortuosity may occur in a wide range of ocular disorders. When retinal vascular tortuosity involves both arteries and veins, and presents unilaterally and without hemorrhage, a diagnosis of Wyburn Mason syndrome (WMS) should be considered due to the potential morbidity and mortality associated with cerebral involvement. Magnetic resonance imaging (MRI) and MRI angiography (MRA) are important tools for identifying cerebral arteriovenous malformations (AVMs), but these imaging modalities have limited spatial resolution to detect very small vascular lesions. Annular array contact ocular ultrasound is a new imaging modality capable of detecting small intraorbital AVMs. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:239-243.].
