Objective To evaluate the efficacy and safety of latanoprost versus travoprost for primary open-angle glaucoma (OAG) and ocular hypertension (OH). Methods All the randomized controlled trials (RCTs) about treating primary open-angle glaucoma and ocular hypertension with latanoprost and travoprost were collected by searching MEDLINE, EMbase, OVID and CNKI. The assessment of methodological quality and data extraction of the included studies were performed independently by two reviewers, and the meta-analysis was conducted with RevMan 5.0 software. Results A total of 13 RCTs involving 1 433 patients were included. The results of meta-analyses showed that, a) At the second week, travoprost showed greater intraocular pressure (IOP) lowering efficacy compared with latanoprost (WMD= –1.47, 95%CI –2.62 to –0.33). At the first month (WMD= –0.50, 95%CI –1.52 to 0.52) and the sixth month (WMD= –0.12, 95%CI –0.85 to 0.61), the difference of IOP reduction between latanoprost and travoprost group was not significant; and b) The latanoprost-treated group showed fewer reported conjunctival congestion than the travoprost-treated group (OR=0.47, 95%CI 0.35 to 0.63). The difference in adverse events of eye pain (OR=0.55, 95%CI 0.27 to 1.12) and iris or skin depigmentation (OR=1.25, 95%CI 0.53 to 2.92) between latanoprost and travoprost group was not significant. Conclusion Latanoprost and travoprost are comparable in lowering IOP for OAG and OH patients. Latanoprost shows greater ocular tolerability with lower incidence of side effects as conjunctival congestion. This conclusion is not powerful enough in proof due to the medium methodology quality of the included studies, so a large number of high-quality RCTs with large sample are needed for objectively, entirely and precisely evaluating the efficacy.

Methods Thirty-two eyes of 19 patients with primary open-angle glaucoma diagnosed between January and December 2009 were chosen to be the study subjects. The patients received 2% cartelol hydrochloride eye drops twice a day for one week. IOP and OPA before and after using cartelol were measured by dynamic contour tonometry (DCT). Blood pressure and heart rate were detected at the same time. The variations of IOP and OPA were analyzed by SPSS 14.0. t test and Pearson correlation analysis were applied. Results The mean IOP and OPA before and after using cartelol were respectively (22.76±4.29) mm Hg (1 mm Hg=0.133 kPa) vs. (17.79±2.93) mm Hg, and (3.47±1.00) mm Hg vs. (2.63±0.86) mm Hg. Both of them decreased significantly after the use of cartelol (P＜0.01). OPA was obviously correlated with IOP both before and after using cartelol (r=0.444, 0.364; P=0.011, 0.040). OPA and IOP had no correlation with blood pressure and heart rate. Conclusions OPA and IOP decreases signifficantly after the use of 2% carteolol hydrochloride. OPA is signifficantly correlated with IOP. OPA and IOP have no correlation with blood pressure and heart rate.
Objective To explore the diagnostic value on 24 hour monitoring of intraocular pressure (IOP) for primary open angle glaucoma (POAG). Methods A prospective study was applied, and a total of 372 subjects through January 2012 to May 2015 for 24 hour IOP monitoring were collected successively, including 137 subjects (271 eyes) with glaucoma (glaucoma group) and 235 subjects (470 eyes) with non-glaucoma (Control group). Data was analyzed using SPSS 13.0 software, and the Kappa statistics was used to evaluate concordance between 24 hour monitoring of IOP and gold standard for POAG diagnosis. Results The mean value of IOP at all monitoring period in glaucoma group was significant higher than that in the control group (P < 0.001). The peak of IOP occurred at 6:00 am and 10:00 in the glaucoma group, and the fluctuation value of IOP in women patients at night (especially at 22:00 pm) was higher than that of men (t=2.064, P=0.04). The sensitivity and specificity of 24 hour IOP monitoring for POAG were 97% and 78.7%, respectively, and with a high consistency comparing to the result of gold standard for POAG diagnosis, with the Kappa values of 0.707 (P < 0.000 1). Conclusion 24 hour IOP monitoring is efficacy and convenient tool, which can be applied alone or combined with other tools to assist early diagnosis patients who are suspected with POAG, so as to improve the diagnostic accuracy.
ObjectivesTo systematically review the association between the SIX6 gene rs10483727 mutation and primary open angle glaucoma (POAG).MethodsPubMed, Web of Science, The Cochrane Library, CNKI, WanFang Data and VIP databases were searched to collect case-control studies on the SIX6 gene rs10483727 polymorphism and primary open angle glaucoma from inception to December 28th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by Stata 12.0 software.ResultsSeventeen case-control studies in 16 papers were included, involving 9 886 patients and 19 663 controls. The results of meta-analysis showed that rs10483727 polymorphism in SIX6 gene was associated with the risk of POAG in the Asians and Caucasians. However, no association was found in the Africans.ConclusionsThe current evidence shows that rs10483727 polymorphism in SIX6 gene is associated with the risk of POAG in the Asians and Caucasians.
ObjectiveTo evaluate the efficacy and safety of phacoemulsification cataract extraction combined with 180° trabeculotomy assisted by gonioscopy (GT) and combined glaucoma filtration surgery (GFS) in the treatment of primary open angle glaucoma (POAG) with cataract. MethodsThe patients with POAG and cataract in the ophthalmology center of the People’s Hospital of Leshan from June 2021 to March 2022 were included. The patients were divided into GT group and GFS group according to surgical methods. Intraocular pressure (IOP), best corrected visual acuity (BCVA) logMAR, number of anti-glaucoma drugs used, success rate, and complications were compared between the two groups after 1-year followed-up. ResultsA total of 27 patients (43 eyes) in the GT group and 26 patients (34 eyes) in the GFS group were included. There was no significant difference in baseline between the two groups (P>0.05). BCVA logMAR in the GT group was lower than that in the GFS group at 1 year after surgery, the difference was statistically significant (P<0.01). The postoperative IOP in GT group was lower than that in GFS group, the difference was statistically significant (P<0.05). The difference in total effective rate, the number of anti-glaucoma drugs and the incidence of complications between the two groups were not statistically significant (P>0.05). ConclusionPhacoemulsification cataract extraction combined with GT is safe and effective in the treatment of POAG with cataract and has a good effect on reducing IOP.
