Abstract
Background Deep sclerectomy (DS) is a non-penetrating surgical procedure for glaucoma, reducing the resistance to aqueous outflow and lowering intraocular pressure while maintaining a physiological barrier between the anterior chamber and the sub-scleral space. This offers a lower complication profile than penetrating procedures, though with less intraocular pressure (IOP) reduction. Methods We retrospectively reviewed the electronic record for all DS undertaken at our hospital (a tertiary care center) over 14 years, collecting data on demographics, diagnosis, IOP, visual acuity, complications, medications, and further procedures required. Results Eighty eyes of 69 patients underwent DS, with a mean follow-up period of 53.5 months. The mean pre-operative IOP was 23.55 mmHg (range 11-52, standard deviation 8.46); the mean final IOP was 13.61 mmHg (range 5-35, SD 4.73), with a mean reduction of 42.21%. The mean change in glaucoma medications was -1.64. 78.40% experienced a reduction in glaucoma treatment. Post-operatively, 43.80% had no complications; this improved to 85.0% when numerical hypotony and raised IOP without visual sequelae were excluded. Further procedures required included Nd:YAG goniopuncture (10%), bleb needling (13.75%) or revision (7.5%), iridectomy (3.75%), goniosynechiolysis (1.25%), and autologous blood injection (1.25%). Two eyes were converted to trabeculectomy peri-operatively, with seven overall (8.75%) requiring trabeculectomy over the course of follow-up. 3.75% underwent glaucoma drainage device implantation, and 3.75% underwent cyclodiode laser. Conclusion We have found DS to be a safe, effective procedure for selected patients where trabeculectomy has a high likelihood of failure or where a higher IOP can be tolerated.

Abstract
Background: The purpose of this study is to evaluate the outcome of deep sclerectomy (DS) as a secondary procedure following failed ab-interno XEN gel stent implantation in patients with open-angle glaucoma. Methods: Prospective, single-center, non-randomized, interventional study. Consecutive eyes that underwent mitomycin C (MMC) augmented XEN gel stent surgery, with uncontrolled intraocular pressure (IOP) or signs of disease progression, were included to undergo MMC-augmented DS. Primary efficacy outcome was surgical success, defined as complete when the unmedicated IOP was 12 mmHg or less, or 15 mmHg or less and 20% lower than at the timing of XEN failure and defined as qualified when the IOP fulfilled the same conditions with fewer medications than before deep sclerectomy. Secondary measures were mean reduction in IOP and in the number of medications, and the rates of complications. Results: Seventeen eyes were enrolled with a mean age of 72.1 ± 8.2 years (66.7% women). The mean follow-up was 20.1 ± 4.9 months, with more than 12-month data available from 15 eyes. Following DS, IOP decreased significantly from 22.6 ± 5.3 mmHg to 12.3 ± 5.5 (45.6%; p < 0.001). Antiglaucoma medications dropped from 1.1 ± 0.9 to 0.3 ± 0.7. Complete success was obtained in 40% of eyes using the threshold of 12 mmHg or less and a 20% decrease of IOP, and in 60% using the 15 mmHg or less threshold. Adverse events were observed in 20% of eyes (bleb leakage (13.3%); hypotony (6.7%)). No cases of choroidal detachment or hypotony maculopathy were reported. Conclusions: Failed XEN gel stent implantation does not seem to negatively affect the safety and efficacy of subsequent deep sclerectomy surgery.

Abstract
AIM To compare the clinical efficacy and safety of non-penetrating glaucoma surgery (NPGS) plus phacoemulsification (Phaco-NPGS) and NPGS-alone. METHODS We systematically searched various databases and reviewed studies that had evaluated the effects of Phaco-NPGS or NPGS-alone for patients with glaucoma. Primary outcomes included postoperative intraocular pressure (IOP) and the number of postoperative antiglaucoma medications. Secondary outcomes were the prevalence of complications, incidence of needling or goniopuncture, and surgical success rate. RESULTS In total, 380 and 424 eyes in NPGS-alone and Phaco-NPGS groups respectively were included. Both postoperative IOP and number of medications were significantly lowered in the Phaco-NPGS group than that in the NPDS-alone group [weighted mean difference (WMD)=-1.12, 95% confidence interval (CI): -2.11 to -0.12, P=0.03; WMD=-0.31, 95%CI: -0.53 to -0.09, P=0.006]. Moreover, Phaco-NPGS had a significantly lower prevalence of complications and postoperative procedures compared to NPGS-alone, while no significant difference existed for surgical success. CONCLUSION Phaco-NPGS superior to NPGS-alone in the reduction of IOP and medications. Phaco-NPGS can be recommended for glaucoma patients with coexisting cataracts owing to its superior efficacy, fewer complications, and postoperative procedures.

Abstract
PURPOSE To compare a modified incision technique with classic scleral flap dissection for canaloplasty with canal expander regarding efficacy and safety. METHODS In a prospective randomized pilot study of 32 eyes of 16 patients with primary open-angle glaucoma, access to Schlemm's canal was created by deep lamellar dissection (scleral flap excision, group 1) or by vertical cut-down incision (group 2). Following canal opening and viscodilation with microcannula and sodium hyaluronate, two Stegmann Canal Expanders were implanted, and the scleral flap or vertical incision, respectively, was closed watertight. RESULTS Mean preoperative intraocular pressure (IOP) was 34.9 mmHg ± 6.7 [standard deviation (SD)] in group 1 and 33.8 mmHg ± 7.7 (SD) in group 2 (p = 0.66); mean postoperative IOP without medications was 14.3 mmHg ± 2.9 (SD) in group 1 and 14.8 mmHg ± 5.2 (SD) in group 2 at 1 month (p = 0.76), and 14.4 mmHg ± 1.9 (SD) in group 1 and 16.8 mmHg ± 3.1 (SD) in group 2 at 12 months (p = 0.01). Overall, there was a significant preoperative-postoperative IOP difference between groups (19.4 mmHg ± 10.1, group 1; 16.6 mmHg ± 8.9, group 2; p = 0.02). Surgery type had a significant effect when adjusted for preoperative IOP, cup-disc ratio, eye side, follow-up number and surgery type (p < 0.01, anova). No filtering bleb was observed in either group. Intra- and postoperative complications were rare and included peripheral Descemet's membrane detachment (3), microhyphema (2) and cannulation into the anterior chamber (1). CONCLUSIONS In this intra-individual comparative study of ab externo canaloplasty with the canal expander, IOP reduction was substantial in both groups and slightly greater in the group with deep scleral flap excision. Additional IOP reduction by transscleral drainage through the Descemet's membrane window and intrascleral lake is suggested.

Abstract
AIM To study the long-term efficacy and safety of modified viscocanalostomy in Chinese people with open angle glaucoma (OAG). METHODS This retrospective study included a total of 100 eyes from 100 Chinese patients with medically uncontrolled OAG. All the patients underwent modified viscocanalostomy with injection of viscoelastic material in the surgically created ostia of Schlemm's canal (SC). The modifications included peeling of the inner wall of SC and the juxtacanalicular meshwork, use of mitomycin C, and loosely suturing the superficial scleral flap. Intraocular pressure (IOP), visual acuity, number of medications, laser goniopuncture data and complications were recorded. The definition of complete (qualified) success was an IOP equal to or lower than 21, 18, 16 mm Hg without (with or without) anti-glaucoma medications. RESULTS The mean IOP was 33.5±9.9 mm Hg before surgery, 15.2±3.6 mm Hg (mean IOP reduction of 51%) at 5y after surgery, and 15.6±2.8 mm Hg (mean IOP reduction of 49.9%) at 10y after surgery (P<0.001). The number of anti-glaucoma medications dropped from 2.39±0.5 preoperatively to 0.47±0.8 at 5y and 0.67±0.8 at 10y postoperatively (P<0.001). The follow-up period was 104.5±37.0mo. The qualified success rate for an IOP of 21, 18 or 16 mm Hg or less was 84% [95% confidence interval (CI): 0.80-0.88], 73% (95%CI: 0.68-0.78), and 59% (95%CI: 0.52-0.66) after 5y, and 80% (95%CI: 0.76-0.84), 69% (95%CI: 0.64-0.74), 51% (95%CI: 0.44-0.58) after 10y, respectively. There was a relationship between age, preoperative IOP and success rate (P<0.01, P<0.05). A total of 31 eyes (31.3%) in 31 patients underwent laser goniopuncture, decreasing the IOP from 22.9±4.3 mm Hg to 16.3±2.5 mm Hg (P<0.01). Neither blebitis nor endophthalmitis occurred. CONCLUSION Modified viscocanalostomy could be performed to lower IOP, decrease multiple anti-glaucoma drops use as well. It's a safe procedure with less complications over 10y in Chinese individuals with OAG.

Abstract
PURPOSE To examine longer-term postsurgical safety and efficacy of a new expander for Schlemm's canal. METHODS In a non-comparative, prospective study, 42 White patients with medically uncontrolled primary open-angle glaucoma (POAG) underwent primary canaloplasty with >2-year follow-up. The bleb-independent procedure comprised catheter-assisted canaloplasty and implantation of two Stegmann Canal Expanders to maintain trabecular distension and canal patency over 180°. Intraocular pressure (IOP), glaucoma medication use and complications were assessed. RESULTS Mean IOP was 26.8 ± 5.6 mmHg presurgery, 12.8 ± 1.5 mmHg at 6 months, 13.2 ± 1.2 mmHg at 12 months and 13.3 ± 2.5 mmHg at 24 months (p < 0.001). Rate of complete success, defined as IOP ≤21, ≤18 and ≤16 mmHg and a ≥ 30% IOP reduction, was 85% (95% CI: 0.76-0.95), 85% (0.76-0.95) and 82% (0.70-0.96) at 12 months and 83% (0.73-0.94), 80% (0.70-0.92) and 80% (0.70-0.92) at 24 months. Preoperative factors were not significant predictors of ≤16 mmHg IOP reduction: IOP (hazard ratio [HR]: 0.68; 95% CI: 0.44-1.04; p = 0.08), mean visual defect (1.06; 0.90-1.20; p = 0.47), number of medications (0.59; 0.17-2.14; p = 0.42) and age (0.96; 0.87-1.13; p = 0.41). Number of medications dropped from 2.8 ± 0.4 presurgery to 0.2 ± 0.5 postsurgery (p < 0.001). Mean preoperative best-corrected visual acuity was 0.19 ± SD 0.21 (range: 0-1.6), and logMAR was similar to 0.23 ± 0.16 (range: 0-1.6; p = 0.42) after a mean follow-up of 27.4 months. Complications included peripheral Descemet's membrane detachment (7.2%) and trimming of the expander (4.7%) during surgery, and transient microhyphaema (23.8%) and IOP elevation (7.2%) postsurgery. CONCLUSION Canaloplasty with the Stegmann Canal Expander was a safe and effective procedure to reduce IOP in White patients with moderate to advanced POAG.

Abstract
Objective The aim of this study was to determine the safety and efficacy of combined phacoemulsification plus Intraocular lens (IOL) implantation with deep sclerectomy augmented with mitomycin C (MMC) and sub-flap implantation of amniotic membrane for the management of uncontrolled, chronic, primary open-angle glaucoma patients. Methods This prospective study included 41 patients with chronic, primary, open-angle glaucoma and cataract uncontrolled with medical treatment who underwent combined phacoemulsification augmented with mitomycin C (MMC) application and amniotic membrane implantation under the scleral flap. Intraocular pressure (IOP), visual acuity, glaucoma medications, stabilization of visual field, complications, and viability of the success rate were assessed a 36-month follow-up period. Results The mean age of cases was 54.8 ± 5.3 years. Sixty-one percent of cases were males, and 39% were females. The mean IOP decreased from 23.8 ± 1.8 mmHg preoperatively to 16.8 ± 2.3 mmHg postoperatively. The overall success rate was 97.5, 95, and 92.7% in the first, second, and third year, respectively. The overall success rate was 90% in the first year, but that decreased to 85.3 and 78% in the second and third year, respectively. Qualified success was 7.5, 10, and 14.7% in the first, second, and third year, respectively. Failure was recorded as 2.5, 5, and 7.3% in the first, second, and third year, respectively. IOP reduction was sustained through the follow-up period. Visual acuity improved from 0.13 ± 0.06 to 0.9 ± 0.07 (p < 0.001). The visual field improved significantly in the first assessment, from 14.0 ± 2.7 preoperatively to 12.6 ± 2.6 at three months postoperatively (p < 0.001), after which it became stable for the remainder of the follow-up period. One hundred percent of cases were on three anti-glaucoma drugs preoperatively, while postoperatively, 12.2% were on three drugs, 4.2% were on two drugs, and 82.9% were controlled without anti-glaucoma treatment. There were minor postoperative complications all of which were minor, such as a spike in the post-operative IOP and the formation of fibrinous material in the anterior chamber, both of which were treated medically without any adverse effects on the final results. Conclusion Amniotic membrane implantation in conjunction with MMC application may be an effective alternative to expensive implants in deep sclerectomy combined with phacoemulsification, and this approach can be used safely in advanced cases.

Abstract
AIM To evaluate the long-term efficacy and safety results of viscocanalostomy and phacoviscocanalostomy. METHODS The charts of 49 glaucoma patients who underwent viscocanalostomy or phacoviscocanalostomy surgery between February 1999 and August 2004 were reviewed retrospectively. Thirty-one eyes of 21 glaucoma patients who underwent filtering procedure with a postoperative follow-up of at least 5y were included in the study. Results of complete ophthalmologic examinations were recorded and statistically analyzed. Long-term surgical outcome was defined as an overall success when intraocular pressure (IOP) was found as ≤20 mm Hg with or without antiglaucomatous medication at the last follow-up visit, while it was defined as a complete success when IOP was measured ≤20 mm Hg without antiglaucomatous medication. RESULTS Mean age was 68.1±9.6y (range: 32-81y). Mean follow-up time was 101.5±27.3mo (range: 60-144mo). Viscocanalostomy was performed in 8 eyes (25.8%) and phacoviscocanalostomy was performed in 23 eyes (74.2%). The mean preoperative IOP was 23.1±7.6 mm Hg with 2.1±1.0 medications, while mean IOP was 16.8±3.8 mm Hg with 0.9±1.1 medication at the last follow-up visit. Both the IOP decrease and the reduction in the antiglaucomatous medication were statistically significant (P<0.001 and P<0.001). No case required further glaucoma surgery. Overall success and complete success were found as 87.1% and 51.6%, respectively. Complete success rate was statistically higher in phacoviscocanalostomy group compared with the viscocanalostomy group (P=0.031), however there was no significant difference in overall success rate between two groups (P=0.072). CONCLUSION Both viscocanalostomy and phacoviscocanalostomy provide good IOP reduction in the long-term period.

Abstract
PURPOSE To study the safety and long-term efficacy of classic viscocanalostomy in patients with open-angle glaucoma (OAG) in different populations. METHODS A total of 726 eyes of 726 patients from Europe or South Africa with primary OAG (POAG) and pseudoexfoliative glaucoma (PXFG) were included in this retrospective multicentre study. Complete (qualified) success was defined as an intraocular pressure (IOP) equal to or lower than 21, 18 and 16 mmHg without (with or without) medications, respectively. A failed procedure was defined if IOP was above 21 mmHg, not controllable by laser goniopuncture or medications. RESULTS The mean IOP before surgery was 42.6 ± 14.2 mmHg for all patients, 29.6 ± 6.6 mmHg for European patients and 48.1 ± 12.9 mmHg for African patients. The follow-up time was 86.2 ± 43.1 months. Mean IOP was 15.4 ± 3.6 mmHg at 5 years, 15.5 ± 4.4 mmHg at 10 years and 16.8 ± 4.2 mmHg at 15 years. The qualified success rate for an IOP of 21, 18 or 16 mmHg or less after 5 years was 92% [95% confidence interval (CI) 0.88-0.96], 70% (95% CI 0.63-0.77) and 43% (95% CI 0.36-0.51) in European patients, and 90% (95% CI 0.87-0.93), 77% (95% CI 0.74-0.81) and 67% (95% CI 0.63-0.72) in African patients, respectively. There was no difference between the success rate for POAG and PXFG for an IOP of 21, 18 or 16 mmHg or less at 5 years (p = 0.64, p = 0.20, p = 0.22, respectively). Laser goniopuncture was performed postoperatively on a total of 127 eyes (17.7%), lowering the pressure from 23.1 ± 1.9 mmHg to 15.0 ± 2.2 mmHg. There were no significant complications, in particular, no blebitis or endophthalmitis. CONCLUSION Viscocanalostomy produced a sustained long-term reduction of IOP with a low-risk profile in European and African patients with OAG over 12 years.

Abstract
Purpose To evaluate quality of life (QoL) with a new questionnaire after canaloplasty (CP) and trabeculectomy (TE). Patients and methods We assessed outcomes of surgery, rate of revision surgeries, patients’ mood, and influence of postoperative care on QoL, surgery interference with daily activities, and postsurgical complaints. Patients completed the QoL questionnaire 24 months after surgery. Results Patients who underwent CP (n=175) were compared to TE patients (n=152). In the CP group, 57% of patients expressed high satisfaction, while 41% of patients in the TE group said they were highly satisfied. The satisfaction difference was statistically significant (P=0.034). Significantly fewer second surgeries were needed after CP (8% CP versus 35% TE, P<0.001). Patients were more positive in the CP group (54% CP versus 37% TE, P<0.009). Stress related to postoperative care was lower in the CP group compared to the TE group (14% versus 46%). Difficulties with activities of daily living, such as reading, were much lower or even nonexistent after CP, and complaints like eye burning or stinging were significantly lower in the CP group. Conclusions Compared with TE, CP is associated with less QoL impairment and higher patient satisfaction after surgery. However, long-term data on intraocular pressure reduction after surgery are needed to confirm long-term patient satisfaction with this surgery.

Abstract
We present the combined surgery of non-penetrating deep sclerectomy with insertion of the implant in the supraciliary space as an effective and safe surgery for patients with both cataract and primary open angle glaucoma. This study included 20 eyes of 16 patients who were followed up during 12 months. We found a significant intraocular pressure reduction, changing from a preoperative mean of 23 ± 5 mmHg to a postoperative mean of 18 ± 3 mmHg (p<0.002). Similarly, a significant reduction in the number of glaucoma drugs needed was observed, varying from 2.5 ± 0.9 drops per patient to 0.7 ± 0.9 (p<0.0002) at the end of the study. We also report a significant improvement in best-corrected visual acuity, from 5/10 ± 2/10 to 8/10 ± 2/10 (p<0.006), one year after the combined surgery. The only intraoperative complication observed was the microperforation of the trabeculo-descemetic membrane (TDM) and postoperative complications were iris incarceration, seidel test positivity and microhyphema. All these complications resolved successfully.

Abstract
PURPOSE To evaluate the efficacy and safety of combined viscocanalostomy and phacoemulsification (phacoviscocanalostomy) for medically uncontrolled open-angle glaucoma (OAG) with concomitant age-related cataract. DESIGN Prospective, noncomparative, interventional case-series study. METHODS Phacoviscocanalostomy was performed on 50 eyes of 50 consecutive patients with medically uncontrolled OAG and clinically significant age-related cataract. Surgical outcome was defined as an overall success by the following criteria: no visual field deterioration; no optic-neuropathy progression; postoperative intraocular pressure (IOP) </= 20 mmHg and IOP reduction >/= 30% compared to baseline values with or without medication. When medications were not required, success was defined as complete. The surgical outcome and the complication rates were documented and analyzed up to 36 months postoperatively. RESULTS Mean follow-up (+/-SD) was 29.02 +/- 7.09 months. Mean, baseline IOP (+/-SD) had significantly decreased from 23.51 +/- 4.48 mmHg to 14.06 +/- 1.64 mmHg at the last follow-up visit for each patient (p < 0.001). The overall success was 94% at 12 months, 92% at 24 months, and 82% at 36 months. The success was complete in 74% at 12 months, and in 67% at 24 months and at 36 months. No serious complications were documented. CONCLUSION Phacoviscocanalostomy can be considered an efficient and safe alternative surgical modality for medically uncontrolled OAG with concomitant age-related cataract.

Abstract
AIMS To examine whether the early postoperative morphology at the site of sclerectomy, as visualised by ultrasound biomicroscopy (UBM), is an indicator of the mechanisms that lower intraocular pressure (IOP) and/or predictors of the long term outcome of viscocanalostomy. METHODS 15 eyes of 14 patients with medically uncontrolled open angle glaucoma and no history of surgery underwent viscocanalostomy according to Stegmann's technique. Ultrasound biomicroscopy was performed during the first month after surgery. The following parameters were assessed: dimensions of the intrascleral "lake," presence of a filtering bleb, presence of a subconjunctival cavity or a suprachoroidal hypoechoic area, and the thickness of the residual trabeculocorneal membrane. A complete ophthalmological examination was performed the day before and the day after surgery. Follow up visits were scheduled 1 week, 4 weeks, 6 months, and 12 months after surgery. RESULTS At 1 year successful control of IOP (<20 mm Hg) was achieved without further manipulation or medication in six of 15 eyes. The size of the intrascleral "lake" (average 0.62 mm(3)) did not correlate with later IOP; however, a visible route under the scleral flap and accidental perforation of the trabeculocorneal membrane were associated with long term lowering of IOP. Normal thickness of the trabeculocorneal membrane (0.10-0.15 mm) was indicative of IOP control with and without medication. When UBM showed an early collapse of the intrascleral cavity, control of IOP was not achieved. Other UBM findings did not predict long term function. CONCLUSION In accordance with previous studies, the authors found that UBM examination is a useful method to evaluate outflow mechanisms after glaucoma surgery. This study shows that UBM imaging of external filtration during the early postoperative period can be used to predict the success of viscocanalostomy. However, to establish conclusively what parameters of UBM predict successful viscocanalostomy a larger number of patients must be studied.
