The most prevalent use of ocular ultrasonography is to obtain globe length in order to calculate corrective lens power requirements. Other uses include the measurement of tumors including choroidal melanomas [B, E], visualization of lens dislocation [E], and detection of retinal detachment. Ultrasonography is especially useful in cases in which the fundus is obscured from visualization by slit lamp and laser interferometry (IOL Master), as in patients with dense cataracts [B,I]. In this population, the use of ocular ultrasonography may result in earlier detection of ocular melanoma [B].
