Pediatric ocular sonography.

Ultrasound is often used as an adjuvant in the workup of ocular pathology in children. It is particularly useful when ophthalmoscopic examination is limited, such as in the presence of extreme miosis or opaque ocular media. Other indications include assessment of a mass seen at ophthalmoscopy, elucidation of a mass underlying a retinal detachment, ocular trauma, and biometry. In this article, we review normal sonographic technique and ocular anatomy. The sonographic features of common pediatric ocular conditions are presented, with an emphasis on distinguishing features. Correlation, where pertinent, is made with other imaging modalities, such as computed tomography and magnetic resonance imaging. Ultrasound plays a critical role in the clinical diagnostic evaluation of globe pathology.
