Abstract
BACKGROUND Trabeculectomy (TE) with mitomycin C (MMC) is considered the gold standard in glaucoma surgery. A new modification is the use of an Ologen® implant (AEON Astron Europe B.V., Leiden, Netherlands) during TE, which was analyzed and compared to the standard TE in this retrospective study. PATIENTS AND METHODS On 70 eyes Ologen® was applied during surgery (group 2), whereas 98 eyes were operated on without the implant (group 1). Both surgical procedures were compared regarding the efficiency of lowering the intraocular pressure (IOP), the number of glaucoma medications, the rate of complications and follow-up treatment. Data were collected up to 24 months after surgery. RESULTS In group 1 the IOP was lowered from 28.0 mmHg (95% confidence interval, CI 26.6-29.4 mmHg) to 16.0 mmHg (14.0-18.1) after 24 months. In group 2, the pressure dropped from 28.5 mmHg (26.8-30.1) to 14.3 mmHg (11.7-17.0). The IOP reduction was significant in both groups (p < 0.001), there was no significant difference between the groups (p > 0.05). Glaucoma-related follow-up treatments were performed more often in group 1 but the difference was not significant. CONCLUSION Both procedures significantly lower the IOP and the number of glaucoma medications. For our cases, TE with Ologen® and MMC is considered to be superior to TE with MMC regarding the lower rates of follow-up treatments as it is less time-consuming for the patients and the clinic.

Abstract
Background To compare the surgical outcomes and postoperative complications with and without Ologen collagen matrix augmentation during XEN gel stent implantation. Methods We retrospectively analyzed patients who underwent XEN gel stent implantation with an ab externo technique. The amount of intraocular pressure (IOP) reduction, percentage of postoperative complications and additional management, and surgical success defined as IOP reduction greater than 20% compared with the preoperative IOP measurement were compared between Ologen-augmented and non-augmented groups. Groups of patients who underwent XEN gel stent implantation alone and combined with phacoemulsification were analyzed separately. Results A total 103 eyes of 103 participants were included. Of those, 72 eyes underwent standalone XEN gel stent implantation: 42 eyes with Ologen augmentation (Oloxen group) and 30 eyes without Ologen augmentation (Xen group). Thirty-one eyes underwent XEN gel stent implantation with phacoemulsification: 19 eyes with Ologen augmentation (Phaco-Oloxen group) and 12 eyes without Ologen augmentation (PhacoXen group). The surgical success rate at six months postoperatively was not different between the Oloxen and Xen groups (56.4% vs 43.3%, P > 0.05) or between the Phaco-Oloxen group and PhacoXen group (57.9% vs 41.7%, P > 0.05). The prevalence of postoperative hypotony, 5-fluorouracil injections, use of anti-glaucoma medications, bleb needling, and additional glaucoma surgeries was not different between the Oloxen and Xen groups or between the Phaco-Oloxen and PhacoXen groups when assessed six months postoperatively. Conclusions All groups showed significant IOP reduction after XEN gel stent implantation, but there was no significant difference between the Ologen collagen matrix augmented and non-augmented groups in surgical outcomes.

Abstract
Purpose: To comparatively evaluate in Indian eyes with coexisting cataract and primary open-angle glaucoma the outcome of mitomycin C (MMC) and Ologen implant as adjunctives in combined phacoemulsification with trabeculectomy. Methods: Eyes with primary open-angle glaucoma that underwent trabeculectomy and phacoemulsification with IOL implantation with either MMC application or Ologen implant between June 2019 and February 2020 were followed up for 12 months. Thirty-four eyes of 34 participants were studied. The primary outcome was intraocular pressure (IOP), and the secondary outcomes were the number of ocular hypotensives, best distance visual acuity (BDVA), and bleb morphology. Results: In 16 eyes treated with MMC and 18 eyes treated with Ologen implant, it was observed that the mean postoperative IOP (14.62 ± 2.89 mm Hg with MMC and 14.56 ± 4.14 mm Hg with Ologen implant) was not significantly different in both groups (P = 0.47). Number of ocular hypotensives and BDVA were also comparable between the two groups. However, bleb morphology was better with Ologen implantation. One eye in the MMC group developed hypotony which was conservatively managed Conclusion: MMC and Ologen are both effective adjunctives in combined phaco-trabeculectomy. However, the Ologen implant provides better bleb health and safety.

Abstract
PURPOSE The purpose of this study is to evaluate the effectiveness of Ologen collagen matrix (OCM; Aeon Astron Corporation) in the prevention of the postoperative hypertensive phase and on long-term intraocular pressure (IOP) control after Ahmed glaucoma valve (AGV; New World Medical) implantation. DESIGN This is a prospective, randomized, controlled study of 26 patients treated at a tertiary care center, with 13 eyes assigned to each treatment arm. PARTICIPANTS Consecutive patients with refractory glaucoma requiring AGV implantation were enrolled. Refractory glaucoma was defined as IOP >21 mmHg on maximum tolerated glaucoma medications or progressive visual field and optic nerve head changes despite maximal tolerated medical therapy. METHODS In Ologen eyes, a round 12 × 1-mm OCM segment was placed flush over the AGV-FP7 plate immediately before conjunctival closure. Control eyes received conventional AGV surgery without OCM implantation. MAIN OUTCOME MEASURES The primary outcomes were postoperative IOP and requirement of pressure-lowering medications. On the basis of these measures, the rates of complete and qualified success over the course of follow-up were calculated. Complete success was defined as IOP ≤21 mmHg without antihypertensive medications. Qualified success was defined as IOP ≤21 mmHg with or without medications. Frequency of hypertensive phase was also determined. RESULTS Patients receiving Ologen-augmented AGV surgery exhibited significantly lower IOPs compared with control subjects at the 1-, 2-, and 3-month time points (P < 0.04). Maximum mean IOP postoperatively was 25.2 ± 7.4 for control eyes and 16.8 ± 8.9 for Ologen eyes, peaking at month 2 for both groups and stabilizing by month 6. No differences in average number of pressure-lowering medications were detected between groups. There were no statistically significant differences in complete or qualified success rates at 6 and 12 months. The frequency of hypertensive phase was 61.5% in control eyes and 38.5% in OCM-implanted eyes. CONCLUSIONS Ologen collagen matrix-augmented AGV surgery may provide better IOP control in the intermediate postoperative period and blunt the hypertensive phase compared with AGV implantation alone.

Abstract
PURPOSE To compare between mitomycin C alone, porcine extracellular matrix alone, and combined low dose mitomycin C with porcine extracellular matrix in term of efficacy and safety in phaco-trabeculectomy surgery. STUDY DESIGN Prospective comparative. METHODS Sixty eyes of 60 patients complaining of primary open angle glaucoma and cataract, undergoing phaco-trabeculectomy, were distributed into three groups: group I: surgery was augmented with mitomycin C, group II with porcine extracellular matrix, and group III with porcine extracellular matrix combined with low dose mitomycin C. Intraocular pressure was evaluated, postoperatively, at day 1, week 1, and 1, 3, 6, 9, and 12 months. Bleb vascularity, pre- and post-operative intraocular pressure lowering medications, success of IOP control and complications were also evaluated. RESULTS After 12 months, the mean preoperative intraocular pressure (mm Hg) improved from 30.85 ± 4.7, 33.8 ± 4.2, and 31.05 ± 5.4 mm Hg, in groups I, II, and III respectively, to 13.8 ± 4.7 (55.2%), 15.2 ± 4.8 (55%), and 13 ± 4.9 (58.1%) (p > 0.05). Success of IOP control, postoperative IOP lowering medications and complications were comparable (p > 0.05). Bleb vascularity was significantly different (p < 0.05). CONCLUSION Mitomycin C, porcine extracellular matrix and their combination are equally effective in phacotrabeculectomy.

Abstract
AIM To investigate the outcomes of adaptive conjunctival flap advancement surgical techniques with or without scleral graft for patients undergoing revision surgery after trabeculectomy. METHODS This retrospective study included 28 eyes of 28 subjects from December 2015 to April 2018. A group of 15 eyes underwent conjunctival advancement only while the other 13 eyes did conjunctival advancement with partial thickness scleral graft. In both study groups, we considered the intraocular pressure (IOP) as our primary outcome and visual acuity (VA) as our secondary outcome. Both were assessed pre- and post-operatively till the last follow-up possible point. Additionally, we classified the patients according to complete and qualified success criteria. RESULTS The mean age of the conjunctival advancement group was 36.87±19.25y, while it was 44.08±18.04 in the other group. In both study groups, the mean IOP significantly increased after revision surgery at 1, 2, 3mo and the last follow-up visit when compared to prior the surgery (P<0.001). Moreover, VA was significantly improved (P=0.03) in the final follow-up for both surgical techniques. When we compared the change from baseline in both groups, there was no significant difference between IOP improvement in 1mo (P=0.263), while the difference was significant in 2mo (P=0.03), 3mo (P=0.02) and in the final follow-up visit postoperatively. However, this difference was not significant regarding VA (P=0.5). CONCLUSION The both adaptive techniques of conjunctival advancement and conjunctival advancement with scleral graft are effective for treating patients with late-onset hypotony. Yet, more prospective studies are needed to assert upon these results.

Abstract
AIM To evaluate the efficacy and safety of trabeculectomy (Trab) with mitomycin-C (MMC) versus Trab with implant. METHODS Studies published in different languages were retrieved by systematically searching Embase, PubMed, Cochrane library, China Biology Medicine disc, and Google Scholar from 1966 to April 2018, as well as manually examining the references of the original articles. The outcome measures of efficacy covered intraocular pressure, glaucoma medications reductions, and success rate. Safety evaluation was measured by relative ratio of complications. RESULTS A total of 11 studies involving 443 participants were covered in this meta-analysis. The weighted mean difference (WMD) in the percentage of intraocular pressure (IOP) reduction (IOPR%) comparing Ologen group with MMC group was -3.69 (95% CI: -6.70 to -0.68) at 1 month, -2.69 (-5.17 to -0.21) at 3 months, -3.67 (-6.09 to -1.25)at 6 months, -3.24 (-6.08 to -0.41) at 12 months, 1.24 (-9.43 to 11.90) at 24 months, and 1.10 (-10.11 to 12.31) at 60 months, which showed that there was statistically significant difference at 1,3, 6, and12 months after the surgery. A significantly higher incidence of postsurgery hypotony (0.64 (95% Cl: 0.42 to 0.98)) and suture lysis (0.30 (95% CI: 0.10-0.93)) was observed in MMC group. However, there was no significant difference in the reduction in glaucoma medications, success rate, and incidence of other complications.Trab with 0.2 mg/mL MMC presented higher rates of complete success compared with Trab with 0.4 mg/mL MMC (P = .01). CONCLUSION Trab with MMC was associated with a higher IOP-lowering efficacy and a higher incidence of postsurgery hypotony and suture lysis in contrast to that of Trab with Ologen.

Abstract
AIM To assess the efficacy and safety of the Ologen collagen matrix as an adjuvant for combined phacoemulsification and nonpenetrating deep sclerectomy (Phaco-NPDS), in addition to mitomycin C (MMC). MATERIALS AND METHODS This was a longitudinal retrospective comparative study of eyes treated with Phaco-NPDS, with (group 1) or without (group 2) an Ologen collagen matrix implant, in addition to MMC. The main outcome measures were operative success [absolute success: intraocular pressure (IOP) <18 mm Hg and an at least 20% reduction from baseline without medication; relative success: IOP<18 mm Hg and at least 20% reduction from baseline IOP with or without medication], mean reductions (%) in IOP and medication use; number of postoperative reinterventions (goniopuncture, needling, reoperation), and number of complications. RESULTS The mean age of the study population (N=100) was 72.0±9.7 years. Groups 1 (n=51) and 2 (n=49) achieved absolute success rates of 72.5% and 55.1%, respectively (P=0.054), and relative success rates of 90.2% and 83.7%, respectively (P=0.251). From a similar baseline IOP (19.8 and 20.7 mm Hg in groups 1 and 2, respectively, P=0.527), eyes in group 1 achieved a significant lower 12-month IOP (11.7 vs. 14.5 mm Hg, respectively, P=0.002) and a lower rate of medication use (0.2 vs. 0.9, respectively, P<0.001). Eyes in group 2 presented with a higher rate of bleb failure (12.2% vs. 2.0%, P=0.028), leading to a higher rate of needling procedures (38.8% vs. 2.0%, P<0.001) during the postoperative period. CONCLUSIONS The adjunctive use of Ologen collagen matrix in addition to MMC during Phaco-NPDS was associated with a higher rate of absolute success, a lower mean IOP at 12 months, a lower rate of bleb failure, and a lower rate of postoperative bleb needling.

Abstract
Purpose To report long-term safety and efficacy of trabeculectomy with collagen implant in Indian population. Methods All cases of trabeculectomy with Ologen® Collagen Matrix implant performed over a 7-year period from May 2008 through April 2015 at a tertiary referral institute were reviewed. A total of 30 eyes of 28 patients were included in the study with two patients undergoing bilateral trabeculectomy. Outcomes measured included intraocular pressure (IOP) control, number of antiglaucoma medications used, bleb morphology, and complications/reoperations. Results Trabeculectomy resulted in reduction in IOP from 36.46 to 11.65 mm Hg in the immediate postoperative period (day 1), a 68% decrease to 15.18 mm Hg at 84 months (58% decrease). The mean IOP reduction decreased over time from 63% in the first year to 55% after 5 years of follow-up. Fourteen eyes attained a follow-up of 5 years and eight eyes a follow-up of ≥7 years. No sight-threatening complication such as hypotony, bleb leak, and bleb-related endophthalmitis was observed in our series, and only intervention required was 5-fluorouracil needling in one case. Conclusion Ologen-augmented trabeculectomy is effective in controlling IOP over a long-term follow up from minimal 3 to maximal 7 years. No untoward events jeopardizing bleb safety were noted at any time. This modality is a viable alternative for patients with contraindications to use of antimetabolites.

Abstract
Background Many studies have investigated the clinical benefits of Ologen for trabeculectomy. However, its benefits for Ahmed glaucoma valve (AGV) implantation have not been investigated as extensively. The aim of this study was to compare the 1-year outcomes of AGV implantation with and without Ologen adjuvant for the treatment of refractory glaucoma. Methods This retrospective study included a total of 20 eyes of 20 glaucoma patients, who were followed for at least 1-year after undergoing AGV implantation. In 12 eyes of 12 patients, conventional AGV (CAGV) surgery was performed, while in 8 eyes of 8 patients, Ologen-augmented AGV (OAGV) implantation was performed. The outcomes were evaluated according to intraocular pressure (IOP) and the number of IOP-lowering medications. Complete success was defined as IOP ≤ 21 mmHg without medications throughout the 1-year follow-up period, and qualified success was defined as IOP ≤ 21 mmHg with or without medications throughout the 1-year follow-up period. Results The rate of complete success was significantly higher in the OAGV group (50.0%) than in the CAGV group (8.3%) (p = 0.035). There were no significant differences between the two groups in terms of qualified success or incidence of the early hypertensive phase. The IOP changes were similar between the groups within 1-year postoperatively, though the number of IOP-lowering medications was significantly lower in the OAGV group during the early hypertensive phase (p = 0.031, 0.031, and 0.025 at postoperative months 1, 2, and 3, respectively). When subjects were divided into groups according to the occurrence of the early hypertensive phase, the group with early hypertensive phase was more likely to use IOP-lowering medications at postoperative 6 months and 1 year (p = 0.002 and 0.005, respectively). Conclusions OAGV surgery shows encouraging results for patients with refractory glaucoma, specifically with respect to the achievement of complete success and the reduction of the number of IOP-lowering medications during the early hypertensive phase. Furthermore, our results suggest that occurrence of the early hypertensive phase is predictive of which patients will require IOP-lowering medications at postoperative 6 months and 1 year.

Abstract
Several techniques have emerged as complement or replacement for trabeculectomy, the standard surgery for glaucoma. Device-modified trabeculectomy is a recently developed technique whose results compared to the classical technique have not been fully defined. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified eight systematic reviews including 34 studies overall. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded device-modified trabeculectomy probably leads to greater overall success rate and may decrease intraocular pressure more than classical surgery. In addition, this technique would probably have a better safety profile than standard trabeculectomy.

Abstract
Background Antifibrotic agents are commonly utilized to enhance the success rates of trabeculectomy. Novel approaches to further improve success rates and reduce the risks of complications are needed. The purpose of this study was to compare intraocular pressure (IOP)-lowering efficacy and safety of trabeculectomy or combined phacoemulsification and trabeculectomy with mitomycin-C (MMC) vs. Collagen Matrix (CM). Methods A prospective, multicenter, randomized controlled trial was performed. Ninety-five eyes of 94 patients with uncontrolled glaucoma despite medical therapy, without previous incisional glaucoma surgery underwent trabeculectomy (85 eyes) or combined phacoemulsification and trabeculectomy (10 eyes) and were randomized to MMC or CM. One eye of each subject was analyzed. Patients were followed for 24 months. The criteria for complete success were IOP >5 and ≤21 mmHg with at least a 20% reduction below medicated baseline without additional glaucoma surgery or medications. The main outcome measures were complete success rates at 24 months with Kaplan-Meier analysis and incidence of adverse events. Results The baseline IOPs were 20.4 ± 6.0 mmHg and 21.2 ± 6.1 (mean ± standard deviation, p = 0.49) on 3.2 ± 1.1 and 3.1 ± 1.0 medications (p = 0.53) compared to 11.8 ± 5.2 and 12.8 ± 3.7 (p = 0.36) on 0.5 ± 0.8 and 0.6 ± 1.0 medications (p = 0.63) at 2 years in the MMC and CM groups, respectively. Kaplan-Meier analysis demonstrated complete success rates were similar in both groups at 24 months: 38.4 ± 7.6% with MMC and 56.2 ± 7.9% with CM (mean ± standard error, p = 0.112, log rank test); however, a significantly higher incidence of failure due to persistent hypotony was observed with MMC (p = 0.002). Conclusions Use of the CM implant at the time of trabeculectomy or combined phacoemulsification and trabeculectomy is associated with similar complete success rates compared to adjunctive MMC; however, the risk of persistent hypotony is higher with MMC.

Abstract
PURPOSE OF REVIEW This article examines the current literature reporting updates on trabeculectomy techniques, complications, and cost-effectiveness. RECENT FINDINGS Trabeculectomy continues to be the standard for glaucoma surgery when a low intraocular pressure is required. Recent publications describe technique modifications that successfully increase efficacy and lower complications. There is also an ongoing effort to define the role of trabeculectomy in the management of glaucoma from a cost and public health standpoint. SUMMARY The current literature continues to support the use of trabeculectomy as a method of lowering intraocular pressure in glaucoma management. Efficacy has been improved by ongoing surgical innovation, and reported complication rates are lower than those previously noted. Trabeculectomy has a favorable cost-benefit profile when compared with medical therapy or other surgical techniques. In spite of these ongoing changes, trabeculectomy appears to be decreasing in frequency in favor of newer surgeries and medications.

Trabeculectomy with ologen in secondary glaucomas following failed trabeculectomy with MMC: comparative study. Eye (Lond) 2016; 30:1126-34. [PMID: 27256305 DOI: 10.1038/eye.2016.114] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Accepted: 04/20/2016] [Indexed: 11/08/2022] Open
Abstract
PurposeWe aimed to assess the IOP-lowering effect of trabeculectomy with ologen in refractory secondary glaucoma following failed trabeculectomy with mitomycin C (MMC), and to compare its surgical outcome between open angle (SOAG) and angle closure (SACG) cases.MethodsThis is a prospective interventional comparative study conducted on 40 eyes (40 patients) with medically uncontrolled secondary glaucoma. Patients were divided into group A: 18 eyes (18 patients) with SOAG, and group B: 22 eyes (22 patients) with SACG. All patients underwent trabeculectomy with insertion of ologen implant. Intraocular pressure (IOP) measurement, SITA standard perimetry (Central 24-2), spectral domain optical coherence tomography (OCT) for retinal nerve fiber layer (RNFL) thickness, and anterior segment OCT for bleb morphology, were all done pre- and postoperatively. Primary outcome measures were comparing preoperative to postoperative measurements and also comparing these measurements between SOAG and SACG. All patients were examined up to 1 year.ResultsWhen preoperative IOP was compared with postoperative IOP, in each group, there was a statistically significant difference (P<0.001). IOP percentage difference was statistically insignificantly different between both groups except at 1 month. According to Moorfields bleb grading system; postoperative bleb was better than the bleb of the previously failed trabeculectomy (P<0.001), and there was a significant difference between group A and B regarding bleb area. Total success rate was 100%; in group A, complete success was 100%, while in group B it was 72.7% (P=0.016).ConclusionOur results suggest that Ologen may be a useful alternative to MMC in repeat trabeculectomy.
