A simplified B-Scan ultrasonoscope for ocular diagnosis.

The use of B-can ultrasonography in ophthalmology is becoming increasingly important. There are several advantages of the Bronson-Turner system when compared with other B-scan instruments. The unit is quite compact and much less expensive. There is no need for a special laboratory and trained personnel, since it is operated easily by the ophthalmologist. Because a water bath is not necessary, uncooperative patients and children can be evluated. This instrument has been proven reliable and accurate in the diagnosis of retinal detachment, choroidal tumors, and intraocular foreign bodies, and is also capable of revealing more subtle abnormalities such as retinoschisis and vitreous membranes. The Bronson-Turner ultrasonoscope provides the clinician with a valuable instrument to evaluate ocular abnormalities in the presence of opaque media.
