The ultrasound examination of the eye with A and B scan has become one of the principal diagnostic methods for detecting ocular abnormalities in children because it is a non invasive technique and can be performed without resorting to general anesthesia. The authors report the most unusual and interesting cases from 1,226 examinations performed in the Department of Ophthalmology, Istituto G. Gaslini, Genova, Italy, between January 1991 and December 1994.
