Purpose or Case Report: Our educational exhibit will be an ultrasound pictorial review of the normal and pathologic conditions of the orbit in children.
Methods & Materials: Most orbital ultrasound studies at our institution are performed by an ultrasound technologist with both radiologist and ophthalmologist present. Images are acquired in transverse and longitudinal planes utilizing a 15-7 MHz linear high-frequency probe.
Results: Ultrasound imaging features of the normal pediatric orbit will be presented. Pathological conditions of the orbit including the following will also be reviewed: vitreous hemorrhage, persistent hyaloid artery, persistent hyperplastic primary vitreous, coloboma, intraorbital cysts, retinal detachment, thickened cornea, corneal transplant, ruptured globe, optic nerve drusen, dysgenesis of anterior eye structures, micropthalmia and pthisis bulbi.
Conclusions: Ultrasound of the orbit, specifically the globe, can be a routine part of ophthalmologic practice in the outpatient setting. Radiologists may les frequently be called upon to interpret perioperative or emergent orbital ultrasound. This educational exhibit will aid the diagnostic radiologist in understanding and interpreting ultrasound examinations of the orbit/globe in diseases encountered in the pediatric population.
