hypertension... CONCLUSIONS: Bimatoprost/timolol PF demonstrated non-inferiority and equivalence
Effect of timolol on refractive outcomes in eyes with myopic regression after
laser in situ keratomileusis: a prospective randomized clinical trial. 
(length 4 to 8) was used for treatment allocation... CONCLUSIONS: Timolol application is effective for the treatment of myopic
Travoprost 0.004%/timolol 0.5%-fixed combination with and without benzalkonium chloride: a prospective, randomized, doubled-masked comparison of safety and efficacy. [2011.09]
PURPOSE: The purpose of this study is to compare the safety and intraocular pressure (IOP)-lowering efficacy of travoprost/timolol in a benzalkonium chloride (BAK)-free fixed combination preserved with polyquaternium-1 (TRA/TIM BAK-free), with travoprost/timolol-fixed combination preserved with BAK (TRA/TIM), in patients with open-angle glaucoma or ocular hypertension... CONCLUSION: Travoprost/timolol BAK-free demonstrated equivalence to travoprost/timolol preserved with BAK in efficacy. No clinically relevant differences in the safety profiles of travoprost/timolol BAK-free and travoprost/timolol preserved with BAK were identified.
Timolol versus brinzolamide added to travoprost in glaucoma or ocular hypertension. [2011.07]
BACKGROUND: To compare the efficacy and safety of timolol 0.5% versus brinzolamide 1.0% when added to travoprost monotherapy in patients with primary open-angle glaucoma or ocular hypertension... CONCLUSION: Both adjunctive combinations moderately reduced IOP in patients inadequately controlled with travoprost monotherapy, with timolol being slightly stronger 8 hours after instillation. Adjunctive treatment with brinzolamide and travoprost may be an alternative for patients not tolerant or not responsive to treatment with timolol and travoprost.
[Double-masked, phase III comparative study of the combination ophthalmic solution of the 1% dorzolamide hydrochloride/0.5% timolol maleate (MK-0507A) in patients with glaucoma and ocular hypertension]. [2011.06]
CONCLUSION: MK-0507A has a significantly superior IOP-lowering effect relative to timolol. MK-0507A also showed a non-inferior IOP-lowering effect relative to the concomitant therapy. MK-0507A was safe compared to both timolol and concomitant therapy.

Pharmacokinetics, Safety and Tolerability of the Preservative-free Fixed Dose Combination of Tafluprost 0.0015% and Timolol 0.5% Eye Drops [Not yet recruiting]
Effect of Xalacom® (Latanoprost/Timolol) and Combigan® (Brimonidine/Timolol) Fixed Combination on Intraocular Pressure and Ocular Blood Flow in Patients With Primary Open Angle Glaucoma or Ocular Hypertension [Recruiting]
Glaucoma is one of the most common causes of blindness in the industrialized nations. For a
long time glaucoma has been defined as a disease in which high intraocular pressure (IOP)
leads to irreversible optic disc damage and subsequent visual field loss. However, recent
investigations show that IOP is not the only factor that is involved in the glaucomatous
process leading to retinal ganglion cell death. The role of vascular factors in the
pathogenesis of glaucoma has recently received much attention based on animal experiments
and epidemiological studies. The main focus of glaucoma is still directed towards a decrease
in IOP. There is, however, also considerable interest whether antiglaucoma drugs influence
ocular perfusion. Although measurement of ocular blood flow is still difficult, a number of
innovative techniques have been realized which cover different aspects of ocular perfusion.
In the present study XalacomÂ® (latanoprost/timolol) and the fixed combination of CombiganÂ®
(brimonidine/timolol) will be compared with respect to their IOP lowering efficacy as well
as their ocular hemodynamic effects.
Timolol Option for Ulcerated Hemangiomas (TOUCH Trial) [Recruiting]
The purpose of this study is to determine whether Timolol 0. 5% Gel Forming Solution is safe
and effective in promoting wound healing of infantile ulcerated hemangiomas compared with
standard conservative management with topical antibiotic.
Fixed Combination Brinzolamide 1%/Timolol 0.5% Versus Brinzolamide 1% + Timolol 0.5% in Open-angle Glaucoma or Ocular Hypertension [Recruiting]
Eligible patients will be randomized in a 1. 1 ratio to receive Brinzolamide 1%/Timolol 0. 5%
or Brinzolamide 1% plus Timolol 0. 5% two times a day for 8 Weeks. The study treatments will
be compared for mean diurnal intraocular pressure (IOP) change from baseline at Week 8.
Safety parameters measured at 4 study visits: ocular signs, visual acuity, cardiovascular
parameters (blood pressure and pulse), dilated fundus (entry and exit) and adverse events.
Topical Timolol for the Treatment of Benign Vascular Periocular Lesions [Recruiting]
The purpose of this research is to find out if the use of topical timolol 0. 5% solution
applied twice daily will help to shrink rosacea lesions around the eye.
