A hundred and twenty patients (240 eyes) aged 40-65 years (mean age 56.9 +/- 2.1 years) who had non-exudative age-related (AMD) macular degeneration (AMD) were examined. Ultrasound studies, including Doppler color mapping, were conducted to study blood flow in ophthalmic vessels and brachiocephalic arteries. Hemodynamic parameters deteriorated in all patients with non-exudative AMD, which suggests that blood flow deficit in the ophthalmic arterial system, central retinal artery, and posterior ciliary arteries. 88.3% of patients with non-exudative AMD were diagnosed as having brachiocephalic arterial deformities of which bilateral C- and S-shaped pathological tortuosity of carotid and vertebral arteries were most common.
