A comparison of the effects on intraocular pressure of latanoprost 0.005% and the fixed combination of dorzolamide 2% and timolol 0.5% in patients with open-angle glaucoma.
OBJECTIVE
To compare the effects on intraocular pressure (IOP) of latanoprost 0.005% and the fixed combination of dorzolamide 2% and timolol 0.5%.


METHODS
Overall, 226 patients whose IOP was insufficiently controlled by timolol alone were randomized to receive either latanoprost once daily or the fixed combination of dorzolamide plus timolol twice daily. Intraocular pressure was measured at 10:00 am and 5:00 pm at baseline and after 3 months of treatment.


RESULTS
Mean IOP was reduced from baseline in both groups (p < 0.001), with a mean +/- SEM reduction of - 4.3 +/- 0.3 mmHg (19%) for the latanoprost treatment group and - 4.0 +/- 0.3 mmHg (17%) for the dorzolamide plus timolol treatment group. The two therapies were similarly effective in lowering IOP levels (mean difference in reduction: - 0.4 +/- 0.4; 95% confidence interval: - 1.1, 0.4).


CONCLUSIONS
Monotherapy with latanoprost once daily was as effective in reducing mean IOP as the fixed combination of dorzolamide plus timolol twice daily in patients with IOP insufficiently controlled by timolol alone.
