•Analisys of the hemodynamic parameters of the retrobulbar arteries at Color and Spectral Doppler US in patients with glaucoma and healthy control subjects.
•Assessment the diagnostic capacity of colour and energy Doppler Ultrasound with respect to glaucoma retrobulbar alterations.
•Glaucoma is one of the most common and potentially severe ocular diseases.
It is one of the first causes of preventable blindness in western countries.
•Primary open-angle glaucoma (POAG): It is a chronic optic neuropathy of unknown origin,
characterized by a progressive loss of the axons of ganglional cells.
It is linked to an increase of the intra-ocular pressure (higher than 21 mmhg).
•Normal tension glaucoma (NTG): It is similar POAG but it is not related to an increase of...

Stadistical Analysis: fig.
both in its primary open-angle form and in normotensive glaucoma,
acts as a vascular disease resulting in significant haemodynamic alterations.
•Using Colour and Spectral Doppler US techniques we show that certain parameters of ocular blood flow suffer greater alterations in patients having primary open-angle glaucoma than those with normal tension glaucoma
•The Pulsatility Index, Resistance Index and Systole/diastole ratio are the parameters more likely to...
