We searched the Cochrane Library, PUBMED （1966 to 2009）, Embase （1980 to 2009） and CMB-disk （1979 to 2009） for the randomized clinical trials （RCT） concerning the two treatment strategies. The reports, including the papers listed in bibliographies, were evaluated against a set of quality criteria and the RCTs that satisfied the criteria were selected and subjected to Meta analysis by employing the Cochrane Collaboration＇s RevMan 4.5 software package. A total of nine RCTs were included in the study. The analyses of the reports showed that, 12 months after surgery, there was significant difference in the reduction of interocular pressure （IOP） between non-penetrating trabecular surgery and trabeculectomy （Z=6.05 P0.00001）. There also existed statistically significant difference in the reduction of IOP at the censored time between the two procedures （Z=4.92, P0.00001）. Difference in the success rate was also found between the two surgeries （Z=3.82, P=0.0001）. It is concluded that, compared with the non-penetrating trabeculectomy, the traditional trabeculectomy could reduce IOP more and had higher success rate while the non-penetrating trabecular surgery is associated with lower postoperative complications.展开更多

METHODS： This was a multicenter, retrospective, observational study and included POAG patients with or without visually-significant cataracts. The Chinese patients were enrolled from three glaucoma centers and a group of comparable Japanese POAG patients was analyzed from our international Trabectome database. The patients received Trabectome or a combined surgery with phacoemulsification and intraocular lens implantation. The primary outcome was intraocular pressure （IOP） reduction. Secondary outcomes included reduction of glaucoma medications, surgical complications, and success at 2y. Success was defined as： 1） IOP≤21 mm Hg and at least 20% IOP reduction from baseline after 3mo at any two consecutive visits; 2） no additional glaucoma surgery required. RESULTS： A total of 42 Chinese POAG patients from three glaucoma centers were enrolled. Twelve patients underwent Trabectome surgery combined with phacoemulsification and intraocular lens implantation while the remainder underwent Trabectome surgery alone. Thirteen patients had a history of failed glaucoma surgery and were considered as complicated cases. In China data, the mean preoperative IOP was 21.4±1.23 mm Hg. The Trabectome lowered IOP to 17.9±1.8 mm Hg at 2y （P=0.05）. The number of glaucoma medications also decreased significantly from a baseline of 2.0±0.9 to 1.1±0.8 at 2y post-surgery （P=0.04）. The overall 2-year success rate was 78%, with patients undergoing combined surgery having a higher success rate compared with those undergoing Trabectome surgery alone （100% vs 76%）. In Japan data, the mean preoperative IOP was 20.8±7.7 mm Hg. The Trabectome lowered IOP to 12.20±2.0 mm Hg at 2y. The number of glaucoma medications also decreased significantly from a baseline of 2.1±0.9 to 3.4±0.6 at 2y post-surgery. In all patients, no major complications were seen. CONCLUSION： Surgery with the Trabectome appears to be an efficient and safe procedure in Chinese POAG patients in the long-term.展开更多

Although the combined cataract and minimally invasive glaucoma surgeries (MIGS) were an appropriate surgical option, the presence of band keratopathy made it difficult to perform ab interno glaucoma surgery in her right eye (OD);therefore, the corneal opacity was removed using ethylenediaminetetraacetic acid (EDTA) chelation procedure. One month after chelation, microhook ab interno trabeculotomy and cataract surgery were performed successfully. Clear intraoperative visualization of the angle structures is critical for the success of these MIGS procedures. In glaucomatous eyes that require MIGS, EDTA chelation is a good neoadjuvant therapy for coexisting band keratopathy.展开更多

This study was to estimate the overall efficacy of non-penetrating trabecular surgery for open angle glaucoma.Methods The published articles selected for this study were obtained by a computerised Medline and China Biological Medicine Disk search of the literature and a manual search of the bibliographies of relevant articles. Articles meeting the inclusion criteria were reviewed systematically, and the reported data were aggregated using the statistical techniques of meta-analysis.Results A total of 37 articles were included in the meta-analysis. The pooled complete success rates of non-penetrating trabecular surgery with different techniques were: deep sclerectomy single, 69.7% (95% CI: 58.5%-81.0%); deep sclerectomy with collagen implant, 59.4% (95% CI: 47.0%-71.8%); deep sclerectomy with reticulated hyaluronic acid implant, 71.1% (95% CI: 56.8%-85.3%); and viscocanalostomy, 72.0% (95% CI: 57.6%-86.4%). The overall weighted complete success rate of non-penetrating trabecular surgery was 67.8% (95% CI: 61.4%-74.3%).Conclusions Non-penetrating trabecular surgery is the best available therapy method for medically uncontrolled open angle glaucoma with a complete success rate of over 60%. But the different techniques cannot belie the complete success rate of non-penetrating trabecular surgery.展开更多
