Color Doppler imaging of the eye and orbit.

: 1. The use of color doppler imaging (CDI) in ophthalmology is a new and exciting area in vascular imaging. The physiologic information obtained and the anatomy evaluated has been inaccessible by any other noninvasive or invasive technique. 2. Although CDI for ophthalmic use does not, as of this time, have FDA approval, clinical trials have begun. 3. It is our expectation that CDI will be an accurate, reproducible, noninvasive method to assist ophthalmologists in the diagnosis and treatment of patients with orbital and ocular vascular disease.
