Utility of Doppler ultrasound for the study of ocular vascular disease

Abstract

Ocular vascular problems represent an emerging pathology within the activity of the internist. Ocular ultrasound is a widely used technique to evaluate a variety of eye conditions. Specifically, Doppler ultrasound of the ophthalmic vessels has become a very useful tool in diagnosing various eye diseases. Doppler ultrasound allows for examining blood flow in the eye even in the presence of eye opacities that impede viewing the posterior segment of the eye. In this review, we describe the principles and techniques of an ocular vascular Doppler ultrasound examination in clinical practice and provide a general approach to the ultrasound characteristics of the most important vascular eye disorders for internists. These include central retinal artery and vein occlusions, chronic retinal ischemic syndrome, anterior optic ischemic neuropathy, and diabetic retinopathy.
