CANADIAN JOURNAL OF OPHTHALMOLOGY 2024; 59:e124-e129. [PMID: 36481183 DOI: 10.1016/j.jcjo.2022.11.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 10/16/2022] [Accepted: 11/09/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To describe the outcomes of patients who underwent a single ab interno trabeculectomy revision augmented with 5-fluorouracil. DESIGN Retrospective cohort study. PARTICIPANTS All patients who had undergone ab interno trabeculectomy revision at a single tertiary care centre during the 5-year study period. All patients had advanced glaucomatous optic neuropathy, and all treated ages and glaucoma subtypes were included. METHODS Outcome measures included surgical success, number of topical intraocular pressure (IOP)-lowering drops, best-corrected visual acuity, visual field mean deviation, and postoperative complications. Success at 12 months was defined using 2 criteria: criterion A (IOP <15 mm Hg and >20% reduction) and criterion B (IOP <12 mm Hg and >20% reduction). Each success criterion was subdivided into patients who achieved success without topical IOP-lowering drops (complete success) or with topical therapy (qualified success). RESULTS This study included 46 eyes of 46 patients. Of these, 34 patients were followed for 12 months or more to assess surgical success. Success defined by criterion A was achieved by 68% of these 34 patients (53% complete, 15% qualified). Success defined by criterion B was achieved by 47% of these patients (38% complete, 9% qualified). Early hypotony was noted in 68% of eyes but was not associated with negative visual acuity or visual field outcomes. CONCLUSIONS An IOP of <12 mm Hg and a >20% IOP reduction were achieved by 47% of patients overall (with or without topical therapy) at 12 months of follow-up. Transient early postoperative hypotony should be expected following ab interno revision trabeculectomy.

Abstract
OBJECTIVE To describe the 3-year outcomes of patients who underwent ab interno trabeculectomy revision with a translimbal sclerostomy spatula augmented with 5-flourouracil. DESIGN Retrospective cohort study. PARTICIPANTS In this single-centre study, inclusion criteria included patients who were 18 years of age or older with advanced glaucoma who had undergone ab interno trabeculectomy revision with 5-flourouracil due to subconjunctival fibrosis and above-target intraocular pressure (IOP). Patients were required to have a minimum follow-up of 3 years. METHODS The primary outcome measure was IOP. Secondary outcome measures included number of topical IOP-lowering medications, best-corrected distance visual acuity, visual field mean deviation, and postoperative complications. RESULTS Forty-one eyes of 41 patients met the criteria for inclusion. Survival analysis demonstrated success defined by criterion A (IOP <15 mm Hg and >20% reduction) in 44% of eyes without medication (complete success) and 71% of eyes with or without medication (qualified success) at 3-year follow-up. Complete and qualified successes defined by criterion B (IOP <12 mm Hg and >20% reduction) were achieved by 31% and 44% of eyes, respectively. Early complications included transient hypotony in 26 eyes (63%) and transient hyphema in 3 eyes (7.3%). No persistent complications were reported within the 3-year study period. CONCLUSION Ab interno trabeculectomy revision can be an effective technique for achieving a low target IOP in patients with advanced glaucoma in up to 3-year follow-up.

Changes in the morphology of the hyperemic blebs in eyes undergone trabeculectomy with mitomycin C after injection of triamcinolone acetonide during one-year follow-up. Int Ophthalmol 2021; 41:3549-3557.

Abstract
PURPOSE To track changes in the morphology of hyperemic blebs in eyes undergone trabeculectomy with mitomycin C 0.02% (MMC) after triamcinolone acetonide (TA) injection. METHODS A total of 30 eyes of 30 patients with localized or diffuse hyperemia after trabeculectomy with MMC were enrolled in this prospective interventional case series. Two milligrams of TA were injected at the site of maximal injection. Bleb morphology was graded using Indiana Bleb Appearance Grading Scale (IBAGS), and the Moorfields Bleb Grading System (MBGS) 1 week, 1 month, 3 months, 6 months, and 1 year after injection. Failure was defined as intraocular pressure (IOP) more than predefined target IOP for each eye, need for an additional surgical procedure, IOP less than 6 mmHg, and loss of Light Perception (LP) vision. RESULTS A total of 27 patients completed a 1-year follow-up period and were included in the final analysis. The mean time interval from trabeculectomy to injection of TA was 5.98 ± 2.57 weeks. The bleb height and vascularity in the IBAGS system decreased significantly after the intervention (p < 0.05), with an increase in bleb extension (p = 0.006). Using MBGS, the bleb area did not change significantly following TA injection (p = 0.056) but its height and vascularity significantly decreased in both central and peripheral areas and the surrounding conjunctiva (p = 0.032). The development of a mature cataract was the only complication that could be attributed to TA injection. CONCLUSION Injection of TA in hyperemic failing blebs improves bleb morphology by decreasing vascularity and height while increasing the extent with an acceptable safety profile.

Abstract
Purpose: The purpose of this study is to evaluate the factors affecting the success of needling surgery for early filtering bleb failure after trabeculectomy. Methods: Patients who underwent a single needling surgery within 3 months after trabeculectomy were retrospectively evaluated. Glaucoma type, intraocular pressure (IOP), and medical treatments before trabeculectomy; the presence of hypotony after trabeculectomy; bleb type; IOP before needling; lens status; complications; IOP after 1, 6, and 12 months; and medical treatments after needling were recorded. Risk factors were evaluated for complete success at 1, 6, and 12 months after needling. Results: Thirty-three eyes of 33 patients were analyzed. The mean IOP after needling at 1, 6, and 12 months was 16.09 ± 3.70, 15.64 ± 2.68, and 15.79 ± 2.61 mmHg, respectively. The mean age of the patients was 53.97 (25–79) years. The mean IOP after needling at 1, 6, and 12 months was 16.09 ± 3.70, 15.64 ± 2.68, and 15.79 ± 2.61 mmHg, respectively. The pre-needling IOP and IOP decrease on the first day affected the complete and qualified success at 1, 6, and 12 months, but the glaucoma type, presence of hypotony after trabeculectomy, lens status, interval between trabeculectomy and needling, and bleb type were not found to affect success. In the receiver operating curve analysis, the pre-needling IOP value was found to be significant in determining complete success. Complete success at 1 month was more likely when the pre-needling IOP cutoff value was <24.5 mmHg. Conclusion: According to the results of single needling surgery performed within 3 months after trabeculectomy, the pre-needling IOP and IOP decrease with needling were found to be factors affecting success. Regardless of the time between the primary trabeculectomy and needling, effective needling will be successful before the IOP rises to high levels. Keeping the IOP at low values with medical treatment until the needling process is performed will have a positive effect on success.

Abstract
Purpose Infrared monitor-guided bleb revision (IRGBR), an alternative needling system, visualizes anterior-segment tissues around the bleb not visible during needle revision after trabeculectomy. This study determined the safety and efficiency of 5-fluorouracil (5-FU) as an adjunctive anti-metabolite in IRGBR. Methods We retrospectively analyzed 43 consecutive eyes (40 patients; 14 eyes, primary open-angle; 29 eyes, secondary glaucoma) treated with IRGBR for failing filtering blebs. The patients were divided into two groups. The first one had IRGBR without adjunctive 5-FU subconjunctival injection, and the second one had IRGBR with 5-FU. We performed Kaplan-Meier survival analysis using log-rank tests after 2 years of follow-up and Cox proportional hazards regression model to analyze the dependence of the survival time on predictor variables. Two failure criteria were defined as the need for additional surgery for intraocular pressure (IOP) reduction and the IOP at two consecutive follow-up visits based on definition 1, IOP ≧22 mmHg and definition 2, IOP ≧17 mmHg. Results Thirty eyes (29 cases) underwent IRGBR with subconjunctival 5-FU injection (group A in the second term) and 13 eyes (11 cases) without 5-FU (group B in the first term). The success rates 24 months after IRGBR were 73.3 and 23.1%, respectively, in groups A and B based on the definition 1 failure and 56.7 and 7.7% based on the definition 2 failure. Complications included transient bleb leaks (group A, 3 eyes; group B, none) and choroidal detachment (group A, 1 eye; group B, none). No use of 5-FU and IOPs ≧10 mmHg 1 week after IRGBR were significant risk factors. Conclusions Adjunctive 5-FU in IRGBR achieved a better success rate for failing trabeculectomy blebs.

Safety and Efficacy of Bleb Needling with Antimetabolite after Trabeculectomy Failure in Glaucoma Patients: A Systemic Review and Meta-Analysis. J Ophthalmol 2020; 2020:4310258. [PMID: 33335782 PMCID: PMC7722638 DOI: 10.1155/2020/4310258] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Revised: 10/11/2020] [Accepted: 10/23/2020] [Indexed: 11/24/2022] Open
Abstract
Background Bleb needling with subconjunctival injection of antimetabolites had become a widely accepted approach for trabeculectomy failure. However, IOP reduction effects, success rates, and complications occurrence for this procedure showed great inconsistency among the different studies. Methods We conducted a literature search on PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. A random-effects model was performed on the extracted data based on the included studies. The intraocular pressure (IOP) and number of antiglaucomatous medications before and after the surgery were pooled for meta-analysis. The success and complication rates were estimated based on the results. Subgroup analysis, sensitivity analysis, and metaregression were applied to explore the origination of heterogeneity. Results Thirty-seven studies with a total of 2182 patients were finally included in our review. For the present meta-analysis, the overall effects of bleb needling at the last visit revealed a reduction in IOP of 9.74 mmHg (95% confidence interval (CI) [8.85, 10.63]), 45.9% (95% CI [39.0%, 53.0%]) for complete success rate, and 70.4% (95% CI [63.5%, 77.0%]) for qualified success rate. Application of mitomycin C (MMC) and 5-fluorouracil (5-Fu) during the procedure were efficacious for IOP control during the follow-up. Metaregression revealed that possible origination of heterogeneity was baseline IOP before bleb needling, revealing a trend that higher baseline IOP correlated with a greater IOP reduction results (p < 0.001). For safety profile, conjunctival haemorrhage (5.7%, 95% CI [2.5%, 10.1%]), hyphema (5.5%, 95% CI [3.0%, 8.7%]), and bleb leakage (5.0%, 95% CI [3.2%, 7.3%]) had the highest estimate of incidence. An increasing number of needling was the main risk factor for needling failure. Conclusion Bleb needling with antimetabolites could be considered an effective and safe procedure after trabeculectomy failure. After the process, patients will gain IOP control and reduce antiglaucomatous medications for at least six months with 5-Fu or MMC. Meanwhile, the overall estimates for complications were relatively low in the whole process.

Nox4 Facilitates TGFβ1-Induced Fibrotic Response in Human Tenon's Fibroblasts and Promotes Wound Collagen Accumulation in Murine Model of Glaucoma Filtration Surgery. Antioxidants (Basel) 2020; 9:antiox9111126. [PMID: 33202904 PMCID: PMC7696451 DOI: 10.3390/antiox9111126] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 10/25/2020] [Accepted: 10/26/2020] [Indexed: 01/18/2023] Open
Abstract
Collagen accumulation in sub-conjunctival tissue at the surgical wound is one of the major complications associated with glaucoma filtration surgery (GFS). This process often leads to unwanted fibrotic scar formation at the lesion site and dysfunction of tissues. Previously, we demonstrated that NADPH oxidase 4 (Nox4) is implicated in transforming growth factor-beta (TGFβ)-induced collagen production in ocular fibroblasts and scarring responses in a mouse model of corneal injury. Here, we propose that Nox4 is an important facilitator of TGFβ-induced responses. We tested this hypothesis in human Tenon’s fibroblasts (HTF) and also assessed a role of Nox4 in an experimental mouse model of GFS. TGFβ1 induced Nox4 mRNA expression but downregulated Nox5 in HTF. Targeting Nox4 gene expression with an adenovirus carrying a Nox4 small interfering RNA (siRNA) (Ad-Nox4i) or removal of hydrogen peroxide (H2O2) with EUK-134 (25 μM) in HTFs significantly reduced TGFβ1-induced Nox4 expression, H2O2 production, and collagen synthesis (p < 0.05, n = 3–6). SIS3 (5 μM) that prevents Smad3 phosphorylation is found to suppress TGFβ1-induced collagen production in HTFs. Furthermore, Ad-Nox4i and EUK-134 both abolished TGFβ1-stimulated proliferation of HTFs. We also compared collagen deposition at the wound arising from GFS between wildtype (WT) and Nox4 knockout (KO) mice. Both collagen deposition and fibrovascularization at the wound were significantly decreased in Nox4 KO mice at 14 days after GFS. Our results provide comprehensive evidence that Nox4 is an important mediator for TGFβ1-induced responses in HTFs and collagen deposition in surgical wound following GFS in mice. As such, pharmacological inhibition of Nox4 would be a viable therapeutic strategy for the control of scarring after glaucoma surgery.

Abstract
INTRODUCTION The use of cytostatic drugs such as Mitomycin C and 5-Fluorouracil is well-known in glaucoma filtering surgery, as well as the management of its complications. However, there is a lack of information regarding the preventive measures to be taken by the professional that handles these types of substances. OBJECTIVE Raise awareness among professionals of the risks associated with the use of cytostatic drugs without adequate prevention measures. RESULTS Review of the available literature and legislation on preventive measures in the management of cytostatic drugs in the medical and ophthalmological field. CONCLUSIONS The prevention and awareness of the risks of the qualified professionals that handle these substances is the most important measure to prevent the possible risks. Coordination is necessary with the Occupational Health teams of the Hospital, as well as the professionals and staff involved in the different phases of the process, from the preparation in Hospital Pharmacy to its elimination.

Abstract
PRéCIS:: Bleb needle revision with and without 5-FU showed similar success rates over the course of a long-term follow-up. A greater total number of needle revisions was identified as a risk factor for procedural failure. PURPOSE The purpose of the study was to investigate the efficacy and safety of bleb needle revision with adjunctive 5-fluorouracil (5-FU) subconjunctival injection in large-scaled patients with failing trabeculectomy bleb. MATERIALS AND METHODS A retrospective chart review was performed on a total of 113 eyes of 106 subjects who had undergone trabeculectomy followed by needle revision and been followed up for at least 6 months. The subjects were divided into 2 groups according to whether they had also undergone concurrent adjunctive 5-FU subconjunctival injection. Two definitions of failure were derived irrespective of IOP-lowering medication use and were assessed at each follow-up visit: (1) IOP>21 mm Hg or >85% of preoperative IOP or reoperation for glaucoma, (2) IOP>18 mm Hg or >80% of preoperative IOP or reoperation for glaucoma. RESULTS A total of 78 eyes of 73 subjects underwent the simple needle revision procedure and 35 eyes of 33 subjects underwent needle revision with subconjunctival 5-FU injection. There was no significant adverse event for either group and no significant IOP difference in any of the observational periods between them (P=0.867). There was also no statistically significant difference in the total number of IOP-lowering medications between the groups (P=0.199). The success rate at 24 months after the first needle revision was 45.6% (95% CI: 33.7, 56.7) in simple revision group and 44.6% (95% CI: 27.7, 60.2) in 5-FU needle revision group by failure 1, 36.3% (95% CI: 25.4, 47.2) and 32.9% (95% CI: 18.0, 48.6) by failure 2, respectively. A greater total number of needle revisions was the significant risk factors for needle revision failure (HR=2.25 and P=0.001 according to failure 2). CONCLUSIONS Bleb needle revision with 5-FU subconjunctival injection is a safe procedure for failing trabeculectomy bleb. Bleb needle revision with and without 5-FU were equally likely to succeed.

Abstract
PURPOSE The purpose of this study was to evaluate frequency, safety, and efficacy of needling in patients that underwent XEN Gel Stent implantation. METHODS Retrospective case review of 19 eyes of 57 consecutive patients (61 eyes) with primary open-angle glaucoma or pseudoexfoliative glaucoma that previously underwent implantation of XEN45 alone or in combination with cataract surgery followed by needling procedure with 5-FU. Success was defined at 2 IOP levels: ≤21 mm Hg and ≤15 mm Hg, with or without additional glaucoma medications. Treatment failure was defined as IOP>21 mm Hg or <5 mm Hg, need for additional glaucoma surgery or loss of light perception. RESULTS Totally 19 of 61 eyes that underwent XEN gel implantation had subsequent needling and were included. Preneedling IOP was 26.2±9.5 and postneedling IOP at last follow-up 15.4±3.7 mm Hg (P=0.0001). Overall success rates of 17 (90%) and 13 eyes (69%) were observed at the ≤21 mm Hg and ≤15 mm Hg level, respectively. Preneedling and postneedling visual acuity and number of medications remained unchanged (P>0.05). Two eyes (10%) were categorized as treatment failures. No major complications occurred. Mean follow-up was 203.8±142.2 (range, 22 to 456) days. CONCLUSIONS Needling revision following XEN gel stent implantation showed a good IOP-lowering effect without significant increase in number of antiglaucoma medications, decrease in visual acuity, nor any major complications. Further studies with long-term follow-up and a larger number of patients are needed to fully assess the safety and efficacy of this procedure.

Abstract
Purpose: To evaluate the efficacy and safety of needle revision and examine factors predictive of failure. Methods: In total, 157 eyes of 131 patients that underwent needle revision augmented with either 5-fluorouracil or betamethasone for trabeculectomy failure were included in this retrospective study. Complete failure was defined as additional glaucoma surgery, ciliodestructive procedures, loss of light perception, sight-threatening complications, hypotony maculopathy, and surgical bleb revision. Success was defined as intraocular pressure ⩽ 18 (criterion A), ⩽15 (criterion B), and ⩽12 mmHg (criterion C) reached with (qualified) or without (complete) medications, and absence of any criteria of complete failure. Results: The median (interquartile range) follow-up was 25.0 (41.0) months. Complete failure rates were 19%, 26%, and 31% at 1, 2, and 3 years, respectively. For criterion A, qualified and complete success rates were, respectively, 77% and 69% at 1 year, 66% and 51% at 2 years, and 60% and 47% at 3 years. For criterion B, qualified and complete success rates were, respectively, 67% and 61% at 1 year, 48% and 42% at 2 years, and 44% and 39% at 3 years. For criterion C, qualified and complete success rates were, respectively, 43% and 41% at 1 year, 27% and 25% at 2 years, and 24% and 23% at 3 years. High baseline intraocular pressure and primary surgery were associated with higher and lower risks of complete failure, respectively. Conclusion: Needle revision is an effective and safe procedure to rescue failing trabeculectomy postponing or avoiding further glaucoma surgery. Eyes with low target intraocular pressure may have poor long-term outcomes.

Abstract
To investigate the risk factors for failure of needling revision with 5-fluorouracil (5-FU) and to identify the correlation of outcomes of needling revision and the morphological features of dysfunctional filtration blebs using Moorfields bleb grading system.This retrospective, nonrandomized, comparative case-control study included 41 consecutive patients (41 eyes) who underwent 5-FU needling revision for failed or failing filtration blebs between July 2012 and August 2014 in Chang Gung Memorial Hospital, a referral center in Taiwan. The main outcome measures were the bleb survival and the correlation factors of bleb morphology before revision. The secondary outcome measure was the identification of any study factor associated with bleb failure.Forty-one eyes of 41 patients were included in this study. The most frequent glaucoma diagnoses were 10 cases (24%) of neovascular glaucoma and 8 cases (19%) of chronic open-angle glaucoma. Survival of bleb at 6, 12, and 24 months was 42%, 39%, and 23%. Fourteen cases (34%) maintained overall success at the last follow-up, with an average follow-up of 22.7 ± 9.4 months (range: 12-48 months). The central bleb area and height were significantly different between the successful needling group and the failed needling group (P = 0.03 and 0.04, respectively). Further trend test confirmed that smaller central bleb extension and flatter height were associated with a higher chance of failure (P = 0.02 and 0.02, respectively). Time from initial trabeculectomy to needling of less than 4 months and higher intraocular pressure (IOP) in the first postoperative week also led to significantly higher risk for failure (P = 0.01 and 0.03, respectively).A small central area and the flat height of dysfunctional blebs were more likely to fail after the needle revision. Cautious case selections, taking account of the time from the initial filtering surgery and postoperative IOP, may improve the surgical outcome.
