  • Vitreous surgery for severe ocular trauma

    Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)

  • Effectiveness of Somatostatin Analogs versus Placebo for Graves’ Ophthalmopathy: A Meta-Analysis

    Objective To systematically evaluate the effectiveness of somatostatin analogs versus placebo for Graves’ ophthalmopathy (GO). Methods Such databases as PubMed, EMbase, The Cochrane Library, WanFang Data, CNKI, VIP and CBM were searched to collect the randomized controlled trails (RCTs) about somatostatin analogs for Graves’ Ophthalmopathy (GO) pulished by March 2012, while the bibliographies of the included literatue were also retrieved. According to the inclusion criteria, two reviewers screened literature, extracted data and assessed the quality of the included studies. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 5 RCTs involving 210 patients were included. The results of meta-analysis showed that somatostatin analogs could reduce the clinical activity score (CAS) of GO patients (MD=0.58, 95%CI 0.02 to1.13, P=0.04), but the effects in reducing the degree of proptosis (mm) was still unverifiable (MD=0.21, 95%CI –0.14 to 0.56, P=0.24). It did not show obvious effects for diplopia, orbital volume, intraocular pressure, visual acuity or the restriction of eye movements. The existing evidence could not confirm that somatostatin analogs were effective for GO (OR=1.32, 95%CI 0.45 to 3.9, P=0.61). Conclusion Somatostatin analogs can reduce the CAS of GO patients, but without significantly clinical significance. Moreover, the effect of reducing proptosis is sitll unverifiable. So the existing evidence cannot confirm that somatostatin analogs are effective for GO. For the quality and quantity limitation of the included studies, this conclusion needs to be proved by performing more high quality RCTs.

  • Diagnostic Value of Enzyme Immunoassay for Chlamydia Trachomatis: A Meta-Analysis

    Objective To evaluate the diagnostic accuracy of enzyme immunoassay (EIA) for chlamydia trachomatis (CT). Methods The diagnosis trials on EIA for CT were searched in the databases such as PubMed (1966 to Dec. 2011), The Cochrane Library (Issue 12, 2011), EMbase (1974 to Dec. 2011), CNKI (1994 to Dec. 2011), VIP (1989 to Dec. 2011) and CBM (1978 to Dec. 2011), meanwhile the manual and other retrieves were also conducted. Two reviewers evaluated the quality of the included trials according to the quality assessment of diagnostic accuracy studies (QUADAS), and then meta-analysis was performed using Meta Analyst and RevMan 5.0 software. Results A total of 17 trials involving 9 461 participants were included. The results of meta-analysis showed that the weighted sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and the area under SROC curve were 0.847 (95%CI 0.571 to 0.995), 0.964 (95%CI 0.890 to 0.994), 25.972 (95%CI 18.587 to 36.293), 0.156 (95%CI 0.114 to 0.212), 228.875 (95%CI 127.136 to 412.028), and 0.953, respectively. Conclusion EIA for CT has higher sensitivity and specificity, so EIA is recommended for preliminary screening CT and diagnosing the highly suspected cases or the patients without obvious signs and symptoms.

  • Non-penetrating Trabecular Surgery versus Trabeculectomy for Open Aangle Glaucoma: A Systematic Review

    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.

  • Effect of Epristeride on Gross Hematuria Secondary to Transurethral Resection of Prostate

    Objective To evaluate the effect of epristeride on gross hematuria secondary to transurethral resection of prostate (TURP). Methods A total of 50 patients with gross hematuria secondary to TURP were divided into two groups: 25 patients were treated with routine treatment plus 5 mg epristeride, twice a day for 3 months, while the other 25 only received routine treatment. Results At the 6-month follow-up visit, gross hematuria recurred in 63% of patients in the control group, but in only 30% of patients in the epristeride group. The difference was statistically significant (Plt;0.05). Moreover, the grade of gross hematuria was significantly lower in the epristeride group (Plt;0.05). Conclusion  Epristeride appears to be effective in treating gross hematuria secondary to TURP.
