With color Doppler imaging, the authors attempted to determine whether glaucoma patients with asymmetric visual field losses had evidence of asymmetric blood flow velocities in the central retina artery despite similar intraocular pressure (IOP) curves in both eyes. They found that eyes with more severe visual field damage had an increased local resistance to blood flow in the central retinal artery. Thus, vascular factors might have important roles in the pathogenesis of primary open-angle glaucoma.
