Abstract

In 31 patients with normal-pressure glaucoma, retinal blood flow, diameter of the retinal vessels and velocity were measured with 2-point fluorometry and automatic measurement of the diameters before and after administration of 0.5\% timolol over 2 weeks. After timolol therapy the tension was significantly decreased (before therapy: 18.26 +/- 2.50; after therapy: 15.61 +/- 2.56 mm Hg, P < or = 0.01). The arterial and venous diameters and blood flow were nearly unchanged, but a slight increase in the arterial and venous velocity was noted. We conclude that timolol does not significantly influence the retinal hemodynamics in patients with normal-pressure glaucoma.
