Color Doppler imaging is of limited value in imaging and velocity measurements of intraorbital arteries when retinal vasoocclusive lesions are present, including hypertensive, arteriosclerotic and diabetic retinopathies. We refined the technique of color Doppler imaging with additional use of echo contrast agents, AlbunexTM and IntraliposTM. The former contains air bubbles of 4μm in diameter and the latter lipid particles of 0.3μm. This feature would enhance the intensity of echo images from the vessels, resulting in a better signal-to-noise ratio. This method allowed satisfactory imaging and velocity measurements in 13 eyes with retinal vasoocclusive disorders in which simple color Dopper imaging was not feasible.
