B-scan ultrasonography of the anterior segment of the eye.

Abstract

SUMMARY B-scan ultrasonograms of the anterior segment were performed on selected patients. The difficulties in imaging the anterior segment are discussed and the value of this technique is demonstrated by illustration of B-scans in different pathological conditions. This technique can often provide important information and allow an early and accurate prognosis.

Eye

“…Relatively high frequency transducers ranging between 8 and 20 MHz are used. 50,55 The anterior lens capsule appears as an echoic, convex curvilinear structure. The vertical (y) axis represents the signal A B C directly on them; they become lost or indistinguishable in near-field reverberation artifact.…”

Diagnostic ultrasound: an aid in the differentiation of anterior segment lesions of the eye

“…Immersion echography of the eye is a well-known technique, that is used mostly for biometric measurements but quite limited for diagnostic reasons [2,6]. The contact-scanners do not visualise the anterior segment and among others for this reason the ultrasonographic diagnostic interest for this part of the eye faded away.…”

Ocular Ultrasonography and Echobiometry in Goats of Different Age and Breed

“…The iris and ciliary body appeared as moderately echoic linear shaped structure. The iris is considered difficult to be imaged but can be seen under ideal conditions in contact with the anterior lens capsule by use of a standoff and a high-frequency transducer (Dziezyc and Hager, 1988;LeMay, 1978;Smith et al, 1986;Wilkie and Gilger, 1998). The iris was located immediately adjacent to the anterior lens capsule with the thicker, more irregular ciliary body lying peripheral (W hitcomb, 2002).…”
