چکیده
PURPOSE To compare the additive effects and safety of 1% brinzolamide/0.5% timolol fixed combination (BTFC) versus the low-dose regimen of 1% dorzolamide/0.5% timolol fixed combination (DTFC) in patients with open-angle glaucoma and ocular hypertension (OAG/OH) following treatment with prostaglandin analogues (PGAs). METHODS A prospective, randomized, double-masked, multicentre, parallel-group and active-controlled study included 201 Japanese OAG/OH patients who had been treated with PGA. Efficacy was assessed as the change in intra-ocular pressure (IOP) from baseline after weeks 4 and 8. Safety was assessed with adverse event rates, ocular discomfort score, blur scale, blood pressure and heart rates, best-corrected visual acuity (BCVA) and slit lamp examinations. RESULTS Intra-ocular pressure (IOP) change from baseline at 9 AM/11 AM pooled over the 8 weeks was -3.3/-3.3 mmHg in the BTFC group and -2.9/-3.4 mmHg in the DTFC group, demonstrating non-inferiority of BTFC to DTFC. Ocular irritation was frequently seen in DTFC group. Although blurred vision was frequently seen in BTFC group, it was transient and blurring became the equivalent 3 min after instillation between two groups. No noteworthy issue was observed in other safety outcome. CONCLUSION Non-inferiority of BTFC to DTFC in IOP reduction was demonstrated after adding onto PGA therapy in Japanese OAG/OH patients. Although the score of blurred vision was transiently higher in BTFC than DTFC, treatment difference decreased and disappeared with time. Thus, BTFC can be considered as a safe and effective agent for glaucoma treatment.

Brinzolamide 1%/timolol 0.5% is a new fixed-combination for the treatment of open-angle glaucoma or ocular hypertension. Brinzolamide/timolol has a favorable safety profile, with an incidence of ocular burning and stinging <5%. Published data show that brinzolamide 1%/timolol 0.5% and dorzolamide 2%/timolol 0.5% have similar efficacies for lowering intraocular pressure (IOP). There is some evid...

OBJECTIVE To compare the safety and effectiveness of fixed-combination regimes (latanoprost- timolol and brinzolamide 1% compared to dorzolamide 1%/timolol and latanoprost) in open-angle glaucoma patients after switching from a combination of three topical antiglaucoma eye drops. METHODS We conducted an open, randomized 12-week multicenter prospective study. We randomly allocated 39 patients ...
