Erythrocyte deformability measurements in patients with glaucoma.
Erythrocyte deformability and aggregability, fibrinogen plasma level, and hematocrit were measured in patients with primary open-angle glaucoma and in age-matched control subjects. Only one parameter, red blood cell rigidity, as evaluated by the Hanss filtration technique, was found significantly elevated in glaucoma patients. This erythrocyte abnormality, which corroborates previous data on blood viscosity, could be an important factor in the pathogenesis of optic nerve damage and could support the hypothesis of a primary oxidative stress in glaucoma.
