Aim: This study was designed to compare the bimatoprost/timolol combination and dorzolamide/timolol combination in glaucoma for efficacy, safety, and cost-effectiveness in a local population of Trichy in the state of Tamilnadu.
Materials and Methods: Eight-week, randomized, parallel group, open-label study was conducted on 48 patients of open angle glaucoma or ocular hypertension. After initial clinical assessment and baseline investigations, bimatoprost/timolol combination (Group A) was prescribed to 22 patients (2 patients lost after initial assessment) and dorzolamide/timolol combination (Group B) to 24 patients. The patients were reviewed after second and eighth weeks for cure rate and adverse drug reaction monitoring.
Results: At the end of 8 weeks, the mean reduction in intraocular pressure from baseline was 13.04 mmHg (95% confidence interval (CI): 10.67-14.70) with bimatoprost/timolol combination once daily (P < 0.01) and 9.46 mmHg (95% CI: 7.47-10.5) with dorzolamide/timolol combination twice daily. Both the treatments were safe. Cost-effective range of bimatoprost/timolol combination was lower than that of dorzolamide/timolol combination.
Conclusion: The fixed combination of bimatoprost/timolol was slightly more effective than that of dorzolamide/timolol combination in reducing IOP, and both treatments were generally well tolerated. Bimatoprost/timolol combination was more cost-effective (cost-effective analysis) than dorzolamide/timolol combination.
