Local fibrinolytic activity of human optic nerve vessels.

The local fibrinolytic activity of the human optic nerve vessels was investigated in 25 eyes obtained at autopsy using Todd's fibrinolysis autography. The veins generally showed higher fibrinolytic activity than the arteries except for the central retinal vessels, as was the case in the systemic blood vessels. Out of 25 cases, 6 (24%) showed a lower activity in the central retinal veins than in the arteries, 7 (28%) a higher activity in the veins than in the arteries and in 12 (48%) the tendency was transitional.
