Ultrasound in the Evaluation of Leukocoria

Abstract

Infantile leukocoria, a white pupillary reflex, is the result of various neoplastic, inflammatory, hemorrhagic, or congenital ocular conditions. Combined B and A scan ultrasonography is a safe, easily performed, highly informative diagnostic technique which aids in the identification of ocular pathology (even when ophthalmoscopic examination is precluded). This report summarizes the clinical course, pathologic findings, and acoustic characteristics of retinoblastoma, persistent hyperplastic primary vitreous, Coats' disease, retrolental fibroplasia, vitreous hemorrhage, congenital cataract, and ocular toxocariasis.
