Abstract
BACKGROUND To compare the bleb morphologies of phacoemulsification combined with Ex-PRESS implantation (Phaco-ExPRESS), phaco trabeculectomy (Phaco-Trab), and trabeculectomy (Trab) in postoperative two years. METHODS Patients with primary open-angle glaucoma (POAG) with or without cataracts were included in this study. All patients underwent surgeries of either Phaco-ExPRESS, Phaco-Trab, or Trab. The morphologic structures of the filtering bleb, including microcysts area, hyperreflective dot density, and stromal connective tissue under in vivo confocal microscope (IVCM), were compared between the three groups. The data were collected preoperatively and postoperatively at 2 weeks, 1 month, 3 months, 6 months, 12 months, 18 months, and 24 months. RESULTS Eighty-nine eyes from 89 patients were enrolled, including 32 in the Phaco-ExPRESS group, 25 in the Phaco-Trab group, and 32 in the Trab group. In a 24-month follow-up, bleb morphologies in Phaco-ExPRESS were similar to the Trab group. The area of epithelial microcysts was significantly increased in Phaco-ExPRESS and Trab groups while significantly decreased in Phaco-Trab. At postoperative 24 months, the complete success rate was 65.1% in Phaco-ExPRESS, 32.0% in Phaco-Trab, and 59.4% in the Trab group (P = 0.03). The phaco-Trab group had more postoperative anti-glaucoma medications than the other two groups (P < 0.05). CONCLUSIONS Phaco-ExPRESS group and Trab group had similar blebs morphologies in IVCM, with larger microcyst area, looser connective tissue, and less inflammation than Phaco-Trab, indicating that the function of blebs in the Phaco-ExPRESS and Trab group, was more potent than that of Phaco-Trab. All these surgical methods provided adequate IOP control, but Phaco-Trab required more anti-glaucoma medications.

Abstract
INTRODUCTION To compare the effect of three different anti-inflammatory regimens consisting of preservative-free dexamethasone (DEX), diclofenac (DICLO) eye drops, and their combination (DEX + DICLO) following trabeculectomy on early postoperative inflammation. METHODS A prospective randomized controlled trial. Sixty-nine patients undergoing trabeculectomy were randomized to receive either postoperative treatment with topical DEX (n = 23), topical DICLO (n = 23), or a combination of topical DEX and topical DICLO (n = 23) after trabeculectomy. The primary outcome was the anterior chamber flare measurement in the first 3 months postoperatively. Secondary outcomes included intraocular pressure, central corneal thickness, conjunctival injection, and number of cells in the anterior chamber from baseline to 3 months postoperatively. RESULTS Anterior chamber flare reached a maximum 1 day after trabeculectomy with an increase of 55% (95% CI 37-73%) for DEX, 64% (95% CI 47-82%) for DICLO, and 57% (95% CI 39-75%) for DEX + DICLO and returned to near pre-operative values 6 weeks after surgery. There were no significant differences in anterior chamber flare [effect size for DICLO: 0.16 (95% CI - 4.3 to 4.6), effect size for DEX + DICLO: 0.09 (95% CI - 4.1 to 4.3)], intraocular pressure, central corneal thickness, conjunctival injection, or number of cells in the anterior chamber between DEX, DICLO, or DEX + DICLO groups. CONCLUSION We found that topical diclofenac was not statistically different from topical dexamethasone in controlling early postoperative inflammation after trabeculectomy, while combining diclofenac and dexamethasone offered no added anti-inflammatory control compared to dexamethasone alone.

Abstract
PRCIS Individuals prescribed ibuprofen after trabeculectomy have better postoperative intraocular pressure (IOP) control and a higher chance of bleb survival despite being at a higher risk of scarring. PURPOSE To investigate the effects of early adjunctive oral ibuprofen treatment on IOP and bleb failure in eyes at high risk of scarring. METHODS In these retrospective analyses, 288 eyes of 273 patients (mean ± SD age: 68.56 ± 10.47 y; 32.60% females) with primary glaucoma who underwent trabeculectomy/phacotrabeculectomy at the Singapore National Eye Centre between April 2020 and April 2021 with a follow-up duration ≥1 year were included. Of these, 77 (26.7%) eyes deemed to be at high risk of scarring were administered oral ibuprofen ≥3 months postoperatively (mean ± SD ibuprofen administration duration: 4.08 ± 2.28 wk). Participant's IOPs at baseline and at postoperative weeks 1, 2-3; and months 1, 2, 3, 6, and 12 were recorded. Bleb failure was defined as 2 consecutive IOP readings of >21, >18, and >15 mm Hg, and/or requiring remedial postoperative laser or surgery. RESULTS The ibuprofen group experienced significantly greater postoperative IOP reductions at week 1 [mean difference, 95%CI: -2.89 (-5.22, -0.56) mm Hg] and month 1 [-2.29 (-4.53, -0.05) mm Hg]; and substantially lower odds of bleb failure at the >18 mm Hg [odds ratio, 95% CI: 0.39 (0.20-0.79)] and >15 mm Hg [0.52 (0.29-0.94)] thresholds, compared with the non-ibuprofen group. No differences in adverse ocular hypotony events were observed. CONCLUSION Early adjunctive oral ibuprofen administered to individuals at high risk of posttrabeculectomy scarring is associated with greater IOP reductions and reduced likelihood of bleb failure. Our results suggest that oral nonsteroidal anti-inflammatory drugs may be a safe way of improving trabeculectomy survival in high-risk eyes.

Abstract
OBJECTIVES To develop a sustained release 5-fluorouracil (5-FU) implant by three-dimensional (3D) printing to effectively prevent conjunctival fibrosis after glaucoma surgery. METHODS 3D-printed implants composed of polycaprolactone (PCL) and chitosan (CS) were fabricated by heat extrusion technology and loaded with 1% 5-FU. Light microscopy and scanning electron microscopy were used to study the surface morphology. The 5-FU concentration released over 8 weeks was measured by ultraviolet visible spectroscopy. The effects on cell viability, fibroblast contractility and the expression of key fibrotic genes were assessed in human conjunctival fibroblasts. KEY FINDINGS The PCL-CS-5-FU implant sustainably released 5-FU over 8 weeks and the peak concentration was over 6.1 μg/ml during weeks 1 and 2. The implant had a smooth surface and its total weight decreased by 3.5% after 8 weeks. The PCL-CS-5-FU implant did not affect cell viability in conjunctival fibroblasts and sustainably suppressed fibroblast contractility and key fibrotic genes for 8 weeks. CONCLUSIONS The PCL-CS-5-FU implant was biocompatible and degradable with a significant effect in suppressing fibroblast contractility. The PCL-CS-5-FU implant could be used as a sustained release drug implant, replacing the need for repeated 5-FU injections in clinic, to prevent conjunctival fibrosis after glaucoma surgery.

Comparison of Ex-PRESS implantation versus trabeculectomy combined with phacoemulsification in primary open-angle glaucoma: a retrospective in vivo confocal microscopy study. EYE AND VISION (LONDON, ENGLAND) 2022; 9:7. [PMID: 35151343 PMCID: PMC8841063 DOI: 10.1186/s40662-022-00278-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 01/12/2022] [Indexed: 02/05/2023]
Abstract
BACKGROUND To compare the efficacy of Ex-PRESS implantation versus trabeculectomy combined with phacoemulsification. METHODS A retrospective 12-month study on patients with coincident primary open-angle glaucoma (POAG) and cataract. The patients underwent combined phacoemulsification and Ex-PRESS implant (Phaco-ExPRESS, n = 35) or phacotrabeculectomy (Phaco-Trab, n = 35). The morphological structures of the filtering bleb were examined by slit-lamp, anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM). Complete success was defined as postoperative intraocular pressure (IOP) < 18 mmHg without the use of anti-glaucoma medication. Qualified success was defined as postoperative IOP < 18 mmHg with or without anti-glaucoma medications. The data were collected preoperatively and postoperatively at 2 weeks, 1 month, 3 months, 6 months, and 12 months. RESULTS No significant difference in the variables such as age, IOP and perimetry was found between the groups of Phaco-ExPRESS and Phaco-Trab. At the one-year postoperative visit for filtering blebs, Phaco-ExPRESS increased the mean area of epithelial microcysts significantly from 0.10 ± 0.05 to 0.20 ± 0.09 μm2 per μm2, while Phaco-Trab decreased the mean area significantly from 0.08 ± 0.04 to 0.04 ± 0.06 μm2 per μm2. Notably, the hyperreflective dots detected by IVCM decreased by 84.9% in Phaco-ExPRESS but increased by 36.3% in Phaco-Trab. The hyperreflective dots were further identified as neutrophil- and monocyte-like cells. The number of these cells were negatively correlated with the microcysts area (r = - 0.7, P < 0.01) but positively associated with the grade of connective tissue (r = 0.5, P < 0.01). By creating different microstructural changes in the filtering blebs, Phaco-ExPRESS produced a higher complete success rate (84.9% vs. 41.2%, P < 0.01) and significant decrease in the number of anti-glaucoma medications (P < 0.01) when compared with those in Phaco-Trab. However, the qualified success showed no significant difference between the two groups (100.0% vs. 91.2%, P = 0.24). CONCLUSIONS At the one-year follow-up, Phaco-ExPRESS generated better filtering bleb with larger area of microcysts, looser connective tissues, and less inflammation than that of Phaco-Trab, providing adequate IOP control and less IOP-lowering medications. These findings indicate that Phaco-ExPRESS could be more preferred than Phaco-Trab for the treatment of patients with coincident POAG and cataract.

Abstract
Aim and objective This study aimed to evaluate the performance of and indication for different surgical techniques in the management of uveitic glaucoma (UG). Materials and methods A retrospective audit of records of all patients with UG who underwent ≥1 glaucoma surgery, between January 2007 and December 2016. The main outcomes were intraocular pressure (IOP) and the need for antihypertensive medication at each follow-up visit. The total number of surgical interventions needed to control IOP was recorded. Postoperative interventions and complications were analyzed. Results Forty eyes from 34 patients were assessed. Overall, baseline IOP was 30.7 ± 8.2 mm Hg, and postoperative mean IOP at the last visit was 16.4 ± 2.0 mm Hg, with a mean follow-up of 28 months. Antihypertensive medications were reduced from 2.8 ± 0.8 to 0.8 ± 1.2. During the follow-up, 61.8% of the eyes required only one glaucoma surgery. There was no correlation between the location of uveitis and the total number of glaucoma surgeries required. The greatest IOP reductions were in cases treated with non-penetrating deep sclerectomy (21%), Ahmed valve (23%), and cyclophotocoagulation (CPC) (51%); in cases where an Ahmed implant was the first surgical option, a 43% reduction was achieved. Conclusion Filtering procedures, glaucoma drainage devices, and CPC are all good options for IOP control in UG, but all are prone to failure over time. With respect to IOP reduction, the safety profile, and postoperative care, Ahmed implants and CPC might be the best first surgical option. Clinical significance The article highlights the versatility of the surgical techniques required to treat UG, which is one of the most difficult types of glaucoma to manage.

Abstract
Since their first introduction in ophthalmology, the use of NSAIDs (nonsteroidal anti-inflammatory drugs) has been exponentially expanded, with numerous therapeutic applications. Despite their controversial history, they have proven their efficacy as anti-inflammatory agents in a variety of diseases. Nowadays, NSAIDs are part of surgical protocols of the most commonly performed ophthalmic operations, such as cataract or ocular surgery. They are universally implicated in the management of conjunctivitis, retinal and choroidal disease and miscellaneous inflammatory diseases. Moreover, although linked with serious adverse events and toxicities, their therapeutic magnitude in Ophthalmology should not be affected. This review systematically portrays the variety of ocular NSAIDs available to date, along with their differences in their way of action, indications and potential side effects in various ophthalmologic conditions.

Abstract
Surgical outcome after trabeculectomy depends on maintaining a functional bleb which requires a delicate balance between incomplete wound healing to prevent fibrosis and enough wound healing to prevent hyperfiltration. Thus, controlling the inflammatory response is essential. We conducted a systematic review and meta-analysis to compare the effectiveness of different formulations of steroids (topical, systemic and depot) and nonsteroidal anti-inflammatory drugs (NSAIDs) in achieving long-term pressure control with fewer antiglaucomatous medications, preserving visual acuity and visual fields while considering surgical and postoperative complications. We used the PubMed, EMBASE and Cochrane Libraries to identify randomized controlled trials (RCTs) comparing the effect of different formulations of steroids (topical, systemic or depot) to NSAIDs. Data on prespecified outcomes from eligible references were entered into a meta-analysis using the Review Manager 5.3 program. We identified seven RCTs with a total of 342 included patients. Topical steroids were superior to placebo in controlling intraocular pressure (IOP) and reducing the risk of complications. Supplementing topical steroids with a perioperative steroid depot (subtenon or intracamerally) or systemic steroids in the early postoperative period did not provide better outcome or a change in the risk of complications. Addition of topical NSAIDs to topical steroids in patients undergoing trabeculectomy did not change the outcome or risk profile. For patients undergoing phacotrabeculectomy and topical NSAID, there was a nonsignificant trend towards better intermediate IOP control and a reduced need for antiglaucomatous medications compared to topical steroids but there was no difference in effect for patients undergoing trabeculectomy. In conclusion, there is a low level of evidence to support the clinician in deciding which postoperative regime provides a more favourable outcome because of inconsistency in the reported outcomes between studies and a low number of patients for each comparable intervention and outcome. It does seem that topical steroids are better than no anti-inflammatory treatment after glaucoma surgery, but further research is recommended.

Valproic acid exerts specific cellular and molecular anti-inflammatory effects in post-operative conjunctiva. J Mol Med (Berl) 2018; 97:63-75.

Abstract
Valproic acid (VPA) is a histone deacetylase inhibitor used clinically for neurological disorders. It is also potentially useful as anti-fibrotic therapy as it reduced collagen deposition in the post-operative conjunctiva. In this study, we further evaluated the effects of VPA on post-operative inflammation using the mouse model of conjunctival scarring. VPA, injected into the subconjunctiva immediately after surgery, did not cause any adverse tissue response when examined by live microscopy and produced an apparent reduction of proinflammatory and proangiogenic markers in immunohistological examinations. In-depth analyses of the treated operated tissues revealed that VPA selectively inhibited the CD45highF4/80low macrophage subset as well as the production of specific proinflammatory cytokines/ chemokines, including CXCL1, IL-5, IL-6, and IL-10 which were reduced by ≥ 2.0-fold. VPA also specifically reduced tissue NF-кB2 p100 protein by mean 3.87-fold. On conjunctival fibroblasts, VPA treatment resulted in decreased secretion of specific cytokines, including CCL2, VEGF-A, and IL-15. In the presence of TNF-α, VPA inhibited the induction of specific cytokines/chemokines, notably CCL5 and VEGF-A, as well as NF-кB2 p100. In corroboration, VPA suppressed TNF-α stimulation of NF-кB reporter transcription by 1.51-fold. These data indicate that VPA can modulate both proinflammatory cellular and molecular targets in a selective manner and may therefore attenuate surgery-induced conjunctival inflammation. These and previous findings suggest that, by suppressing key mediators of both inflammation and fibrosis, VPA is a useful therapeutic for improving surgical outcome involving the conjunctiva. KEY MESSAGES: VPA inhibited recruitment of a CD45highF4/80low macrophage subset. VPA reduced chemokine and cytokine levels in treated tissues. VPA selectively suppressed tissue NF-кB2 p100 levels. VPA suppressed TNF-α induction of chemokines, cytokines and NF-кB2 p100 expression. VPA suppressed TNF-α stimulation of NF-кB reporter.

Abstract
PURPOSE To examine the rates of intermediate-term intraocular pressure (IOP) control after trabeculectomy with adjunctive mitomycin C (MMC) and assess for associated complications. METHODS Medical records of patients undergoing primary trabeculectomy with MMC at Concord Repatriation Hospital, Sydney between January 1997 and December 2005 were reviewed. All eyes with a minimum of 2-year follow up were included. Follow-up data were collected in a standardized form on postoperative IOP, bleb-related and other complications. Success was measured as IOP ≤ 18 mmHg and ≥ 6 mmHg (criteria 1) with (qualified success) or without (absolute success) the use of glaucoma medications. A secondary outcome measure was an IOP reduction of greater than 20% from baseline (criteria 2). Eyes with preoperative IOP of 18 mmHg or less were included, but also analysed separately to those eyes with preoperative IOP above 18 mmHg. RESULTS Sixty eyes from 42 patients were included in the study, with 3-year follow up on 48 eyes. Mean preoperative IOP was 25.3 mmHg (range 8-45) and mean postoperative IOP was 14.0 mmHg at 1- and 2-year follow up, and 14.7 mmHg at 3 years (ranges: 3-31, 4-30 and 8-45 mmHg respectively). Cumulative success for criteria 1 was 85.0% at 2 years and 83.3% at 3 years, and for criteria 2 it was 80.0% and 79.2%, respectively. The number of eyes on glaucoma medications was reduced from 51 preoperatively to 30 at 3 years. Complications were infrequent. There was one eye with a shallow anterior chamber beyond the immediate postoperative period. One eye required cataract surgery at 1-year follow up. Subgroup analysis was performed using the first operated eye only, and results did not differ significantly from overall results. CONCLUSION MMC-augmented trabeculectomy can significantly reduce IOP in the short and intermediate term, with a favourable safety profile.

Abstract
This prospective observational case series study included 6 eyes of 6 consecutive glaucomatous patients. Each patient underwent trabeculectomy with mitomycin C, and received a 1.25 mg of subconjunctival bevacizumab injection at completion of the trabeculectomy. Study eyes included two with neovascular glaucoma, three with uveitic glaucoma, and one with secondary glaucoma following vitrectomy. All eyes had undergone failed glaucoma laser/surgical treatment or an intraocular surgical procedure. Intraocular pressure (IOP) at the following postoperative visits: preoperative, 1 week, 1 month, 2 months, 3 months, and 6 months, was measured. We also evaluated postoperative bleb findings and complications. IOP measured at each visit was 37.5±14.4 mmHg, 6.2±3.4 mmHg, 8.3±7.2 mmHg, 12.0±4.4 mmHg, 10.8±3.1 mmHg, and 12.2±3.3 mmHg, respectively, for each visit. All eyes had functioning blebs with normal IOP at postoperative 6 months with no additional IOP-lowering medication.

Abstract
OBJECTIVE To provide data on the results of patients with nonneovascular juvenile glaucoma who had Molteno implant surgery in the province of Otago, New Zealand. DESIGN Prospective noncomparative case series. PARTICIPANTS Fifty-five operations in 52 eyes of 45 patients with nonneovascular juvenile glaucoma who had Molteno implant surgery between the ages of 9 and 49 years from 1976 to 2003 at Dunedin Hospital and were observed for a mean of 12.2 years (range, 0.1-25). INTERVENTION Insertion of a Molteno implant. MAIN OUTCOME MEASURES Intraocular pressure (IOP) and visual acuity (VA). RESULTS Insertion of a Molteno implant controlled IOP at < or =21 mmHg with probabilities of 0.89 (95% confidence interval [CI], 0.81-0.97) at both 1 and 2 years and 0.85 (95% CI, 0.75-0.95), 0.78 (95% CI, 0.66-0.90), and 0.71 (95% CI, 0.58-0.85) at 5, 10, and 15 years, respectively. Mean VA was 20/100 preoperatively; improved to 20/60 at 1 year; and stabilized at 20/120 at 5, 10, and 15 years postoperatively. Twenty-nine eyes had their preoperative VA maintained or improved at final follow-up, and the VAs of 17 eyes deteriorated but were at least light perception at final follow-up. CONCLUSION The use of Molteno implants in cases of nonneovascular juvenile glaucoma controlled IOP with a probability of 0.71 15 years postoperatively, whereas 53% maintained or improved their vision from their preoperative VA at final follow-up.

Abstract
PURPOSE OF REVIEW Trabeculectomy is an effective operation for lowering intraocular pressure. However, success is limited by complications such as infection, hypotony, and scarring. RECENT FINDINGS These complications, which are increased by antifibrotic use, can be reduced with attention to surgical technique. We highlight the benefit of sub-Tenon anaesthesia, careful choice of the surgical site, fashioning of the scleral flap to produce diffuse aqueous flow, and better intraocular pressure control, maintenance of intraocular pressure, a formed anterior chamber, with outflow control during surgery using an infusion, optimal method of antimetabolites application, new adjustable sutures, and corneal-conjunctival closure techniques. SUMMARY These techniques reduce hypotony, producing a diffuse noncystic bleb with long-term pressure control.
