Role of ultrasonography in childhood eye diseases in a tertiary care setting: indications and scope.

We sought to evaluate the role and diagnostic potential of ocular B-scan ultrasonography in childhood eye disease in an observational cross-sectional study; 1091 patients with a total of 1445 eyes examined were studied. Cataract was the single most common indication for ultrasound followed by corneal pathology, ocular trauma, posterior segment pathology, primary congenital glaucoma, leukocoria, orbital pathology and other disease. Ultrasonography resulted in a change in diagnosis in 198 cases (18%). We conclude that B-scan ultrasonography plays an important adjunctive role in the management of childhood eye disease.
