Ultrasound accurately demonstrates morphologic characteristics of choroidal tumors and associated ocular changes, ie, retinal detachment and vitreous hemorrhage. Serial examinations are valuable in documentation of tumor growth. Acoustic characteristics of choroidal tumors enable differentiation from ophthalmoscopically similar lesions, and prediction of tumor type.

Ultrasound examination is important in eyes with opaque media (cornea, aqueous, lens, vitreous) when choroidal tumor is suspected (10% of enucleated eyes harbor unsuspected malignant melanomas). Ultrasonography is also essential in atypical retinal detachments where choroidal tumor may underlie detached retina, where no break is visible, where there are smooth retinal bullae, where fluid shifts, and where intraocular pressure elevates.

Finally, ultrasound provides acoustic information in ophthalmoscopically visible masses: differentiation from choroidal or retinal detachment, cystic lesion, or subretinal hemorrhage; accurate size and height measurement with serial sectioning; and tumor type characterization by "acoustic profile."
