Diagnostic Ocular Ultrasonography
Since the 1960s ultrasonography has advanced from a research tool limited to the measurement of ocular dimensions to sophisticated imaging modality. The technique is now used extensively at all levels of ophthalmic evaluation. The most common application of diagnostic ultrasonography is for evaluation of eyes with opaque media (e.g., dense cataract or vitreous hemorrhage) or eyes that have sustained extensive ocular trauma with subsequent opacification of the ocular media. Additionally, ultrasonography is valuable for the characterization of ophthalmoscopically visible abnormalities such as choroidal tumors.
