The Role of Color Doppler Imaging in Dysthyroid Eye Disease

Abstract

A better understanding of the nature of dysthyroid eye disease will help in the treatment of the disease as well as form a basis for clinical and pathophysiologic investigations.

With increasing observation of enlarged SOV m dysthyroid eye disease, as detected by CT scan, venous obstruction may play a major role in the pathogenesis of manifestations of orbitopathy in this disease.

Color Doppler imaging is a recent development in ultrasonography that allows for simultaneous two-dimensional structural imaging and Doppler evaluation ofthe blood flow. Doppler information 1s superimposed in color over a conventional gray scale ultrasound image.

The purpose of this work is to evaluate the role of color Doppler Imaging (CDI) in the study of the orbital vascular hemodynamics of dysthyroid eye disease.

The study was conducted on 2 groups:

Group 1: Included 30 patients of dysthyroid eye disease.

Group II: Included 10 healthy volunteers.

All patients and controls were subjected to clinical examinations, laboratory tests, ultrasonographic examinations using AlB scan system, and color Doppler examinations.
