Glaucoma, Blood Flow Velocity
Effects of Non-Specific Endothelin-A Receptor Blockade on Ocular Blood Flow in Patients With Glaucoma
Several lines of evidence suggest now that ocular perfusion abnormalities may contribute to the progression of glaucoma. It has been hypothesised that increased endothelin-1 plasma levels, as seen in patients with glaucoma, may…
