[Color Doppler echography in oculo-orbital diseases]

The orbital color Doppler echography introduces in imaging arsenal, an information about perfusion of parenchymatous organs and vessels, associated to B-scan sonography. The visualisation of orbital vasculature, has opened a new dimension in ophthalmological US exploration, with applications in normal ocular vasculature evaluation, and also, in regional pathological field: tumor, ocular vascular malformations, carotid-cavernous fistulas, central retinal artery and vein occlusion, ischaemic pathology of the optic nerve, micro/macro diabetic angiopathy, the evaluation of diagnosis and therapy in open-angle glaucoma. Adding the power-angio exploration system, combined with dye injection, may increase the vascular informations in the field of oculo-orbital tumoral pathology. A good knowledge of the anatomy and the pathology, as well as, a high experience in Echo-Doppler examination, are considered as fundamentals in a successful approach of this new exploration method.
