Summary

This project purpose is to evaluate the effectiveness, ocular surface quality, medication adherence and quality of life in 46 glaucoma patients in use of three separate drugs (Bimatoprost 0.3%, Timolol Maleate 0.5% and Brimonidine Tartrate 0.2%) comparing with triple combination, Triplenex. In this clinical trial approved by the Unifesp Etical and Research Comitte, volunteer glaucoma patients will be recruited from Unifesp Glaucoma Sector and VerMais Glaucoma Sector. They will be randomly divided em two groups,Group I is going to be treated with Triplenex (1 drop twice a day) and Grupo II with Brimonidine Tartarate (1 drop twice a day), Timolol Maleate (1 drop twice a day) and Bimatoprost (1 drop at night). At baseline visit a complete ophthalmolgical exam will be performed along with three questionnaires ("Ocular Surface Disease Index", "Glaucoma Treatment Compliance Assessment Tool" and "National Eye Institute Visual Function Questionnaire"),retinography, visual field, optic nerve OCT in all patients. This procedure will be repeated at baseline and within 4, 8, 12 weeks.

Detailed description

This clinical study aims to compare the use of the hypotensive eye drop Triplenex, a fixed triple combination (currently available only in Brazil, Mexico, and Chile), with the globally recognized combination of the same drugs administered separately. The combination of the eye drops Bimatoprost 0.3%, Timolol Maleate 0.5%, and Brimonidine Tartrate 0.2% in separate vials is traditionally used in patients with difficult intraocular pressure control or advanced glaucoma that requires a low target pressure for proper disease management. The fixed triple combination intends to improve patient adherence while maintaining the efficacy of intraocular pressure control and progression of glaucoma. This study arises in the context of a lack of literature comparing Triplenex to the three original drugs and the absence of data on its influence on adherence, ocular surface, and the quality of life in the daily lives of glaucoma patients.

Type	Name	Description
DRUG	Triple combination formula	Individuals will be randomly divided em two groups,Group I is going to be treated with Triplenex (1 drop twice a day) and Grupo II with Brimonidine Tartarate (1 drop twice a day), Timolol Maleate (1 drop twice a day) and Bimatoprost (1 drop at night). At baseline visit a complete ophthalmolgical exam will be performed along with three questionnaires ("Ocular Surface Disease Index", "Glaucoma Treatment Compliance Assessment Tool" and "National Eye Institute Visual Function Questionnaire"),retinography, visual field, optic nerve OCT in all patients. This procedure will be repeated at baseline and within 4, 8, 12 weeks.
DRUG	Bimatoprost .03% sterile ophthalmic solution	Individuals will be randomly divided em two groups,Group I is going to be treated with Triplenex (1 drop twice a day) and Grupo II with Brimonidine Tartarate 0.2%(1 drop twice a day), Timolol Maleate 0.5% (1 drop twice a day) and Bimatoprost 0.3% (1 drop at night). At the first visit a complete ophthalmolgical exam which includes ocular surface items (conjunctival hiperemia, keratitis and tear film break up time). Questionnaires are performed ("Ocular Surface Disease Index", "Glaucoma Treatment Compliance Assessment Tool" and "National Eye Institute Visual Function Questionnaire") to assess information about ocular surface adverse effects, quality of life and treatment adherence. Glaucoma exams as retinography, perimetry, optic nerve OCT (optical coherence tomography), central corneal thickness are performed on all patients to evaluate disease's control. This procedure will be repeated at all visits: baseline and within 4, 8, 12 weeks.
