Visual function, optic nerve structure, and ocular blood flow parameters after 1 year of glaucoma treatment with fixed combinations.

No statistically significant differences in visual field or nerve fiber layer thickness were observed between the treatment groups during 12 months of therapy.

Mean increase over 1 year of treatment in ocular perfusion and diastolic perfusion pressures were 10.46% and 10.67% in the DTFC group and 7.47% and 5.61% in the LTFC group, respectively.

Ophthalmic artery resistive index (resistive index) and short posterior ciliary artery resistive index were significantly different at the 12 months visit between the two treatment groups (p=0.05 and p=0.000, respectively): DTFC treatment showed decrease in the resistive index.
