Efficacy and safety of prostaglandin analogues in primary open-angle glaucoma or ocular hypertension patients: A meta-analysis.

To evaluated and compared the efficacy and safety of 3 prostaglandin analogues (0.005% latanoprost, 0.004% travoprost, and 0.03% bimatoprost) in treatment of primary open-angle glaucoma (POAG) or ocular hypertension (OHT). PubMed, Embase, Cochrane library, Web of science, CNKI, Wanfang, and Vip database, published between January 1, 2000 and June 1, 2018, were systematically examined for randomized controlled trials (RCT) based on prostaglandin analogues for POAG or OHT treatment. Statistical analyses including weighted mean difference (WMD) calculation and odds ratio (OR) were performed using Review Manager Software version 5.3. The 17 studies were included in this analysis (N = 2433 participants) with 1∼12 months' follow-ups. The difference of intraocular pressure (IOP) reduction between latanoprost and travoprost group had not significant; there was significant difference of IOP reduction between latanoprost and bimatoprost group in the third month and sixth month; Travoprost was significantly different from bimatoprost in reducing IOP in the third month. Travoprost revealed an elevated risk of conjunctival hyperemia compared with latanoprost. An elevated risk of conjunctival hyperemia and growth of lashes compared with latanoprost. Bimatoprost shows lower ocular tolerability with higher incidence of side effects such as conjunctival hyperemia. 0.03% bimatoprost appears more effective following long time use (3 and 6 month post-treatment) for IOP control compared to 0.005% latanoprost, and is more effective compared to 0.004% travoprost after being used for a certain period of time (3 months post-treatment); nevertheless, 0.005% latanoprost is better tolerated in patients with POAG or OHT.
