461EFFECTS AND SAFETY OF FIXED COMBINATION OF DORZOLAMIDE/TIMOLOL VERSUS LATANOPROST/TIMOLOL IN PRIMARY OPEN ANGLE GLAUCOMA OR OCULAR HYPERTENSION – A META ANALYSISTo compare the efficacy and safety of fixed combination of Dorzolamide/Timolol (FCDT) and Latanoprost/Timolol (FCLT) for the treatment of Primary open angle glaucoma (POAG) and ocular hypertension. Meta analysis of randomized controlled trials. Systematic search of the literature published before 2015 was conducted in Pubmed, Medline, Embase, Cochrane library. Primary studies which compared the effects and efficacy of fixed combination of Dorzolamide/Timolol and Latanoprost/Timolol. Six randomized controlled trials with a total of 701 patients (350 patients in fixed combination of Dorzolamide/Timolol group, 351 in fixed combination of Latanoprost/Timolol group) were included in the Meta analysis. A continuous data was pooled for intra ocular pressure reduction, the Forest plot standardised mean difference/SMD was -0.58; 95% CI= -0.85-0.27; and a total overall effect P value= 0.44, since the overall P value was 0.44(i.e. > 0.05) it shows that the combined effect size was not statistically significant. Therefore, the fixed combination of Dorzolamide/Timolol and fixed combination of Latanoprost/Timolol has no significant effect in intra ocular pressure reduction. Fixed Combination LatanoprostTimolol (FCLT) was associated with equivalent efficacy in IOP lowering comparing with Fixed Combination DorzolamideTimolol (FCDT). However, FCLT was better tolerated than FCDTxiaojuncai168@163.comResearch622016Intraocular pressure,Dorzolamide,Timolol,Latanoprost,Open angle glaucomaSrijana Pradhan Sharma, Cai Xiao JunDepartment of Ophthalmology, Zhongnan Hospital of Wuhan University, No.169 Donghu Road, Wuchang, Wuhan, Hubei, CN 430071,Department of Ophthalmology, Zhongnan Hospital of Wuhan University, No.169 Donghu Road, Wuchang, Wuhan, Hubei, CN 430071
