ABSTRACT

Ocular B-mode ultrasonography (US) has increasingly been useful in characterizing various ocular abnormalities. Though ophthalmoscopy is the most widely used and primary investigation in most of the posterior segment ocular lesions, the same can’t be said all the time specially when the transparent media becomes opaque, mainly due to mature cataract or vitreous hemorrhages etc. Thus, US can guide the ophthalmologist in diagnosing disease and choosing treatment in presence of an opaque media. US is typically ideal for the eye due its superficial location and cystic configuration. Moreover, dynamic study helps distinguish between various conditions that would otherwise be difficult to differentiate in some clinical setting, such as vitreous, retinal, and choroidal detachment. The prevalence of visual impairment and blindness due to diabetic retinopathy (DR) and diabetic eye complications is on the rise worldwide and specially much more prevalent in the western world as a part of the metabolic syndrome. In diabetic patients with an opaque media due to any cause, US can be easily used to assess the prevalence of various ocular abnormalities mainly confined to the posterior segment. Thus, an understanding of the basic anatomy of the eye, the US technique, and common entities that affect the ocular globe will allow radiologists to offer this valuable imaging modality to patients and referring clinicians.
