Abstract
Background: The superficial location of the eye and its cystic composition make ultrasound ideal for imaging the eye. It is a simple, non ionizing, cost effective, real time imaging modality providing detailed cross sectional anatomy of the entire globe.
Objectives: To evaluate the accuracy of B-scan ultrasonography (US) in various types of ocular trauma by comparing the findings with the clinical examination and surgical findings if possible.
Patients and Methods: Descriptive analysis of cases of ocular trauma in patients who presented to Ophthalmology Department, Ain Shams University, in the period from November 2017 to May 2018 to compare clinical and surgical findings in those patients with the ultrasonography findings.
Results: Accuracy of US in the present study in prediction of post traumatic cataract was 80%, lens dislocation was 83.64%, vitreous hemorrhage was 100%, PVD was100%, choroidal detachment was 100%, partial retinal detachment was 96.4% and in detection of metallic IOFB was 100%.
Conclusion: Ultrasound B-scan is an excellent, non-invasive, rapid diagnostic tool in assessing intraocular damage caused by blunt or penetrating eye injuries which most of the time renders ophthalmoscopy impossible due to opacification of light transmitting media. The images provide essential and detailed information about soft tissues damage, helping in the decision regarding early surgery, before chronic changes have occurred.
