Summary
Brief summary
The aim of our research was to assess the safety and efficacy of changing antiglaucoma therapy to the timolol 0,5% / travoprost 0,004% fixed combination administered once daily, from previous monotherapies, in a group of 40 patients with open-angle glaucoma followed for a period of six months.The combination was a valid defense in the treatment of open angle glaucoma
