The quality of included trials was evaluated according to the guidelines developed by the cochrane collaboration. And the outcomes estimating efficacy and safety of two different surgical treatments were measured and synthesised by Rev Man 5.0.· RESULTS： Five randomized controlled trials were selected and included in Meta-analysis with a total of468 patients（468 eyes） with both PACG and cataract. We found that Phacotrabe had a greater intraocular pressure（IOP） lowing effect [preoperative IOP： weighted mean difference（WMD）=0.58, 95% confidence intervals（95% CI,-0.53 to 1.69）, P =0.31; postoperative IOP： WMD =1.37,95% CI（0.45 to 2.28）, P =0.003], a lower number of antiglaucoma medications [risk ratio（RR）=0.05, 95% CI（0.02 to 0.18）, P 〈0.00001] needed postoperatively and less serious damage of optic nerve [RR =0.48, 95% CI（0.21 to 1.07）, P =0.07], but a higher risk of complications[odds ratio（OR）=0.04, 95% CI（0.01 to 0.16）, P 〈0.00001]compared with Phaco. The rest studies indicated that there had no significantly difference between the two surgical methods for postoperative best-corrected visual acuity（BCVA） [WMD =-0.05, 95% CI（-0.14 to 0.05）, P =0.32] and loss of visual field [RR=1.06, 95% CI（0.61 to1.83）, P =0.83].·CONCLUSION： Phaco alone compared with Phacotrabe had a better effect in IOP reduction, whereas the securitydecline.

This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract. Methods This is a comparative case series study. Thirty-one patients （31 eyes） with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone, lOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final lOP less than 21 mmHg without lOP-lowering medication. Results After 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding lOP reduction （（20.59±7.94） vs. （24.85±14.39） mmHg, P=0.614）, complete success rate （88% vs. 71%, P=0.370）, formation rate of functioning blebs （65% （11/17） vs. 93% （13/14）, P=0.094）, and complications （41% （7/17） vs. 57% （8/14）, P=0.380）. lOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group. Conclusion Phacotrabeculectomy and trabeculectomy treatments exhibit similar lOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.展开更多

However,recent randomized controlled trials have demonstrated greater promise of phacoemulsification cataract surgery alone for control of the IOP. In this report we review the current literature to evaluate the impact of cataract surgery upon preventing and controlling primary angle closure diseases.展开更多

METHODS: It was a systematic review and meta-analysis, randomized controlled trials(RCT) and clinical controlled trials (CCT) were collected through electronic searches of the Cochrane Library, PubMed, EMbase, Wanfang Database online, Chinese journal Full-text Database, Chinese Scientific Journals Full-text Database (from the date of building the database to October 2010) We also checked the bibliographies of retrieved articles. M the related data that matched our standards were abstracted. The quality of included trials was evaluated according to the Dutch Cochrane Centre. Rev Man 5.0 software was used for Meta-analysis. RESULTS: A total of 5 RCT and 11 CCT involving 1495 eyes were included. The results of meta-analysis showed that phacotrab+IOL group was superior than trabeculectomy(trab group) (MD -3.93,95% CI [-7.31, -0.54]) which was also superior than phaco+IOL group(MD 0.52,95%CI [0.10, 0.95]) in decreasing Intraocular Pressure(IOP). Phacotrab group(MD -1.45,95%CI [-1.68, -1.22])and phaco group (MD-1.12,95% CI [-1.87, -0.37])are both deeper than trab group in the anterior chamber depth. In increasing the coefficient of outflow facility of aqueous humor (C values) there was no statistical difference in the three groups. And there was no statistical difference between phacotrab groups and phaco groups in visual acuity but phacotrab group was superior than phaco group (MD 1.07, 95% CI [0.73, 1.40])in the use of IOP-lowering drugs. There was no statistical difference among three groups. CONCLUSION: Current evidence suggests that phacotrab+IOL group was superior than tab group which was also superior than phaco+IOL group in decreasing IOP. Phacotrab group and phaco group are both deeper than trab group in the anterior chamber depth. Phacotrab group was superior than phaco group in the use of I展开更多

Of them, 87patients（87 eyes） in group A had underwent phacotrabeculectomy with intraocular lens（IOL）implantation, and 75 patients（75 eyes） in group B had underwent sequential surgery with IOL implanted. Best-corrected visual acuity（BCVA）, intraocular pressure（IOP）, complications and anterior chamber angle（ACA）were measured.· RESULTS： Demographic characteristics of the two groups were similar. A mean follow-up period was 15±6mo（range 13 to 24mo）, a mean IOP of 12.14 ±5.32 mm Hg in group A and 11.38 ±4.06 mm Hg in group B（P =0.84） at the last follow up. The Kaplan-Meier analysis revealed that the cumulative probability of success in both groups was similar（P =0.61）. Anterior uveitis and hypotony were the most common complications in group A, whereas group B experienced shallow anterior chamber with trabeculectomy. With the exception of anterior uveitis, no complications occurred to 11 trabeculectomized eyes. All postoperative measurements of anterior chamber showed statistically significant differences in each group according to the preoperative data（P〈 0.05）. However,fewer changes occurred in group B than in group A.· CONCLUSION： Phacotrabeculectomy and sequential surgery exhibit similar IOP reduction, visual recovery,and complications when treating CACG patients with cataract. However, for a wider ACA, phacotrabeculectomy has demonstrated higher effectiveness than sequential surgery.展开更多
