FIG. 1. — Mean end-diastolic velocities at baseline and follow-up for the study treatment groups. The solid line with solid rhombus corresponds to the dorzolamide/timolol treatment group. The dotted line with solid squares corresponds to the brinzolamide/timolol treatment group. Each point represents the mean value of the indicated hemodynamic parameter. Error bars show 95% confidence interval (CI). (A) Ophthalmic artery. (B) Central retinal artery. (C) Short posterior ciliary artery. • Indicates significant effects of dorzolamide/timolol compared with baseline and brinzolamide/timolol (P < 0.001). ‡ Indicates significant effects of brinzolamide/timolol compared with baseline (P < 0.001). + Indicates no significant differences between dorzolamide/timolol and brinzolamide/timolol treatment groups.
