Ultrasound has become as indispensable as indirect ophthalmoscopy or slit lamp in the evaluation of the eye. It is an important adjuvant for the clinical assessment of a variety of ocular and orbital diseases. Advances in instrumentation, higher frequencies and better sensitivity and resolution have resulted in continuous improvement in image quality. Very high-frequency ultrasound uses frequencies in the range of 35-100 MHz to show greater detail of the anterior segment. Penetration is limited for these higher frequencies to only a few millimeters and, thus, only the anterior vitreous behind the ciliary body and lens can be imaged. High-frequency ultrasound in the range of 20-30 MHz has a penetration of approximately 10 mm and can be used for posterior pole evaluation of the retina and choroid.
