Influence of latanoprost on retrobulbar hemodynamics. Influence of latanoprost on ocular perfusion. Overview of the results from CDI measurements before and one month after regular application of latanoprost: Increase of blood flow velocities were statistically not significant (n = 10). Bold printed measures were subjected to statistical testing; all other parameters were observational only.
