- Abstract
Purpose: to find the existence of alterations in retrobulbar hemodynamics in patients with progressive glaucoma comparing with the patients with stable disease. Methods: 35 patients with open angle glaucoma (POAG) were included in the study. Eye checks were carried out for 24 months at an interval of four months which consisted in determining Tio, FO examination and computerized perimetry to determine disease progression. Also, color Doppler ultrasound was performed and systolic velocities were measured and enddiastolic ophthalmic artery (OA), central retinal artery (ACR) and posterior ciliary arteries (PCA). Resistivity index was calculated automatically by the device. Results: Among the 35 patients, 9 experienced disease progression through the evolution of perimeter deficits. Compared with patients with stable disease, patients with disease progression in the measurements showed a significant increase in Doppler resistance index (RI) in the ophthalmic artery - averaged 0.80 (p = 0.028) and a low speed in the ophthalmic artery enddiastolic - average 2.32 cm / sec (p = 0.03). Conclusion: In patients with primary open-angle glaucoma and progression of the disease, retrobulbar hemodynamic parameters measurements show a significant increase in vascular resistance and a decrease in ophthalmic artery enddiastolic velocity in ophthalmic artery.
