Ultrasonography is a powerful noninvasive tool for the accurate diagnosis and effective management of intraocular tumors. Distinguishing ultrasonographic characteristics of intraocular tumors result from their different histopathologic compositions that can be evaluated with one-dimensional reflectivity analysis (A-scan) and two-dimensional acoustic section (B-scan). Information regarding location, shape, and acoustic characteristics is considered together to aid the diagnosis of intraocular tumors. Determination of size progression and extension is critical in selecting and monitoring management.
