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

Because the part of the globe in direct contact with the transducer cannot be visualised and focussed transducers have poor imaging qualities at a distance less than 5-8 mm from their surface, diagnostic ultrasound of the anterior eye segment has been treated in a stepmotherly way. With a simplified immersion technique we can visualize quite accurately a variety of pathologic conditions of the cornea, anterior chamber, iris, lens and ciliary body. The B-mode information is superior to the A-mode in this part of the eye.
