The influence of primary open-angle glaucoma upon the retrobulbar circulation: baseline, postoperative and reproducibility analysis.

CDI is showing continued promise as a reliable, reproducible method to assess the hemodynamics of a variety of ophthalmic diseases in which vascular perfusion abnormalities are suspect. Moreover, some patients with advanced POAG appears to have abnormalities of the vasculature of the retrobulbar circulation that is corrected by trabeculectomy. Continued CDI clinical correlations with longitudinal studies are now required to elucidate the significance of this technology and these results for individual patients.
