A COMPARATIVE STUDY ON EFFICACY OF FIXED COMBINATION TIMOLOL/BRINZOLAMIDE VERSUS TRAVOPROST MONO-THERAPY IN DRUG-NAÏVE OPEN-ANGLE GLAUCOMA PATIENTS.

Background: Glaucoma is the cause of blindness. Beta blocker and prostaglandins are used as a first line treatment of open angle glaucoma. The exact target with mono therapy for reducing intraocular pressure is achieved within 2 years, so patient prefers fixed dose combination therapy. Objective: For reducing intraocular pressure efficacy, travoprost mono therapy and timolol/brinzolamide fixed dose combination therapy is compared. Material and methods: For 3 months, patients are randomly received 0.5% timolol and 0.2% brinzolamide twice daily and travporost once daily 0.004%.Then compared intraocular pressure, pulse rate, blood pressure, and cup disc ratio over 12 weeks of treatment. Results: 27.99% and 30.49% reduction in intraocular pressure is observed with mono therapy and fixed dose combination respectively. Pulse rate (9beats/min) and systolic pressure reduction by (2.35mmHg) were seen with fixed dose combination but no cup disc ratio observed. Conclusion: It is proved that 0.5% timolol and 0.2% brinzolamide causes more reduction in intraocular pressure than the 0.004% travporost mono therapy. Keywords: Glaucoma, travporost and lantoprost
