Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will use fixed combinations of prostaglandin analogues plus topical beta blockers available on market during 60 days. Patients will be divided in three groups. Each group will recieve one drug. Intraocular pressure will be compared.
If using drugs prior to study, a washout period of 30 days will be necessary.
Half of patients will receive the drug at mornig (8 a.m.) and half at night (8 p.m.). After 30 days they will change the time to use the drug (crossover regarding the instillation time), without washout between these change.
The drugs are: Xalacom (latanoprost 0.005%/timolol 0.5%) eye drop once day; Ganfort (bimatoprost 0.03%/timolol 0.5%) eye drop once day; and Duotrav (travoprost 0.004%/timolol 0.5%) eye drop once day.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Intraocular pressure higher than 21 mmhg
Need to use drops to reduce intraocular pressure
One investigator will evaluate the patients, enroll them and proceed the allocation after use a randomised number generate by a computer program. He will give the drug to the patient and will not participate from statistical analysis.
