[The exacerbating role of the vascular factor in the evolution of open-angle glaucoma].
The paper proposes to study the ophthalmic and carotid circulation of patients with primary open-angle glaucoma in varied stages of evolution.


METHODS
The lot is formed by 8 patients with primary open-angle glaucoma, selected such that one eye to be absolute or quasiabsolute and the congener eye in incipient stage. The average (medium) age is 64 years, the patients having blood pressure within normal limits. The study of ophthalmic and carotid circulation was made by echo-Doppler and the calcul of velocimetric indices.


RESULTS
The resistance index is increased in concordance with the stage of glaucoma. The diastolic flux is the most serious affected. There is no parallelism between the blood pressure value and the grade affectation of velocimetric indices.


CONCLUSIONS
The local vascular diseases, ophthalmic and carotid, influence unsatisfactory the evolution of primary open-angle glaucoma.
