Abstract Background: Primary open-angle glaucoma (POAG) is a very common disorder, and it is the second leading reason that leads to blindness worldwide after cataracts. Previous studies have reported that dorzolamide/timolol-fixed combination (DTFC) can be used to treat patients with POAG. However, there are still inconsistent results. Thus, this study will systematically investigate the efficacy and safety of DTFC for the treatment of patients with POAG.Methods: A comprehensive search will be carried out in the electronic databases of Cochrane Library, MEDLINE, EMBASE, CINAHI, ACMD, China National Knowledge Infrastructure, and Wanfang Data from origin to the March 1, 2020. There are no limitations related to the language and publication status. Only randomized controlled trials that assessed the efficacy and safety of DTFC for the treatment of POAG will be included. Two researchers will independently undertake record selection, data extraction, and methodological quality assessment. Any divisions will be solved by discussion with a third researcher. We will perform statistical analysis using RevMan 5.3 softwareDiscussion: This study will summarize present evidence to identify the efficacy and safety of DTFC for the treatment of POAG through mean intraocular pressure, best corrected visual acuity, contrast sensitivity, bioelectric activity of the retina, rate of progression of glaucoma, quality of life, and adverse events. The results of this study will help to determine whether DTFC is effective and safety for the treatment of POAG.Systematic review registration: INPLASY202040120.

ABSTRACT Background Glaucoma is a leading cause of irreversible blindness. The fundamental problem in medical management of glaucoma is of patient compliance. An ideal drug or a drug combination is needed to slow the progression of this majorly symptomless disease. Aim To compare the efficacy and tolerability of the fixed combination latanoprost and timolol instilled once daily in the evening vs fixed combination of dorzolamide and timolol instilled twice daily in primary open angle glaucoma or ocular hypertension. Materials and methods A 12-week, randomized, open, parallel group study including 50 patients with primary open angle glaucoma or ocular hypertension was conducted at a tertiary care hospital. Patients were randomized to group 1, (fixed combination (FC) latanoprost and timolol eye drops, once daily in evening) and group 2, (FC dorzolamide and timolol eye drops, twice daily). At baseline, 2, 4 and 12 weeks, IOP was recorded at 9 AM and 12 noon. The difference in IOP reduction in two treatment groups from baseline to 12 weeks was the main outcome measure. Results Mean diurnal IOP was similar at baseline for both groups. Mean reduction in IOP from baseline to 12 weeks was 9.92 mm Hg (p = 0.001) in group 1 and 9.22 (p = 0.001) in group 2. The reduction in IOP in both groups 1 and 2 was statistically significant at all time intervals. There was a statistically significant advantage for group 1 at 12 weeks for both time readings (p = 0.013 and 0.002 respectively) as compared to group 2. Conclusion The fixed combination of latanoprost and timolol was more effective than that of dorzolamide and timolol in reducing mean diurnal IOP and both treatments were well tolerated. To confirm further such studies are required. How to cite this article Ratol S, Walia R, Chaudhry M.
