ObjectiveTo systematically review the diagnostic value of optical coherence tomography angiography (OCTA) for primary open-angle glaucoma (POAG). MethodsThe CNKI, WanFang Data, VIP, CBM, PubMed, Embase, Web of Science, and Cochrane Library databases were electronically searched to collect diagnostic test on OCTA for POAG from inception to February 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 15.0 software. ResultsA total of 12 diagnostic tests involving 993 subjects were included. Meta-analysis results showed that the sensitivity/specificity of OCTA for diagnosing peripapillary vessel density, retinal vessel density, and optic nerve fiber changes in patients with POAG were 0.77/0.92, 0.56/0.92, and 0.85/0.91, respectively, and the AUC of the SROC curve was 0.94, 0.92 and 0.95, respectively. ConclusionOCTA has high diagnostic accuracy for POAG. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the association between myopia and open-angle glaucoma (OAG). MethodsForeign and domestic articles published from January 2000 to May 2013 were searched in PubMed, EMbase, WanFang Data, VIP and CNKI for observational studies on the association between myopia and OAG. According to the inclusion and exclusion criteria, the studies were screened, the data were extracted, and the method quality of included studies was assessed. Then meta-analysis was performed using Stata 12.0 software. ResultsEleven cross-sectional studies including 45 996 participants were finally included. The results of meta-analysis showed that, myopia increased the risk of OAG. Besides, the results of subgroup analysis by the severity of myopia showed that, low-degree myopia (more than-3.00 D) increased 1.52 times the risk (OR=1.52, 95%CI 1.23 to 1.88) while middle/high-degree myopia (no more than-3.00 D) increased 2.41 times (OR=2.41, 95%CI 1.91 to 3.03). ConclusionIndividuals with myopia have increased risk of OAG.
Objective To assess the efficacy and safety of a dorzolamide/timolol combination versus latanoprost in the treatment of open-angle glaucoma. Method We searched for randomized control trials concerning a dorzolamide/timolol combination versus latanoprost in the treatment of open-angle glaucoma,in electronic databases , and handsearched some related journals. The quality was evaluated and meta-analysis was conducted using the software RevMan 5.0. Results Six randomized control trials involving 361 patients and 361 eyes were identified. The Meta-analysis showed that at the end of study, there was a statistically significant difference between the two study groups with WMD – 0.49, and 95%CI – 1.06 to 0.07 ( P=0.09) in lowering intraocular pressure; there was no statistically significant difference between the two groups with WMD 1.43 and 95%CI 0.49 to 4.21 (P=0.53); and there was no statistically significant differences between the two groupswith WMD 0.40 and 95%CI 0.13 to 1.26 (P=0.12) in incidence of headache. Conclusion Compared with latanoprost, dorzolamide-timolol combination have increased efficacu in lowering intraocular pressure (IOP).If we want a more reliable result ,we need a large number of multi-centre,double-blinded randomized control trials.

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 identify genes associated with juvenile open-angle glaucoma (JOAG) by screening for gene mutation loci and clinical phenotype analysis in a JOAG family. Methods In January 2021, an ophthalmic examination was performed on members of a family with JOAG. Whole-exome sequencing was done on the proband to look for pathogenic genes. Family members were validated using Sanger sequencing, and a long-term follow-up was conducted. Results Three generations of the family comprised eight individuals, including three patients with JOAG. All patients carried a missense mutation in the MYOC gene c.1130C>G (p.Thr377Arg), which showed autosomal dominant inheritance. Other unaffected family members were not found to have the mutation. Conclusion The c.1130C>G (p.Thr377Arg) mutation in the MYOC gene may be responsible for the pathogenesis of this JOAG family.
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.
Objectives To assess the clinical effectiveness of non-penetrating trabecular surgery versus trabeculectomy for open angle glaucoma. Methods We searched the Cochrane Central Register of Controlled Trials (issue 2, 2007), MEDLINE (1966 to May 2008), EMbase (1980 to May 2008), and CMB-disk (1979 to May 2008). We also hand searched relevant journals and conference proceedings. Data were extracted by two reviewers independently using an extraction form. The Cochrane Collaboration’s RevMan 5.0 software was used for statistical analysis. Results Three RCTs involving 127 participants (144 eyes) with previously untreated open angle glaucoma were included. Meta-analysis showed that compared with non-penetrating trabecular surgery, trabeculectomy increased the proportion of patients with reduced postoperative intraocular pressure (WMD2.78, 95%CI 1.41 to 4.15), improved the operation success rate (RR 0.53, 95%CI 0.37 to 0.77), and reduced the use of postoperative antiglaucoma medication (WMD 0.96, 95%CI 0.84 to 1.08). Non-penetrating trabecular surgery reduced the incidence of postoperative complications (RR 17.00, 95%CI 8.36 to 26.00). Conclusion Since the sample sizes of the included trials are relatively small, and the two procedures are also related to progressive visual field loss and optic disk damage, more well-designed large-scale RCTs are required.
