ULTRASONOGRAPHY of the eye aids the assessment and management of many ocular conditions, and is well tolerated by most dogs and cats. The principal indication for ocular ultrasonography is inability to see into the eye because of conditions affecting the cornea, anterior chamber or lens. Ultrasonography may also help to distinguish between various anterior segment entities that may appear similar ophthalmoscopically (eg, uveal neoplasm, iridociliary cyst and iris bombé), but which require quite different treatments. This article describes how to carry out ocular ultrasonography and, in the boxes on pages 606 to 610, provides a pictorial guide to a variety of abnormalities that may be diagnosed in companion animals using this imaging modality.
