Combined Endoscopic Cyclophotocoagulation and Phacoemulsification Versus Phacoemulsification Alone in the Glaucoma Treatment: A Systematic Review and Meta-Analysis. Cureus 2024; 16:e55853. [PMID: 38590498 PMCID: PMC11001325 DOI: 10.7759/cureus.55853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/09/2024] [Indexed: 04/10/2024] Open
Abstract
The complete safety and efficacy of endoscopic cyclophotocoagulation (ECP) remain unclear in the literature and, to our knowledge, there are no current meta-analyses on phaco-ECP versus phacoemulsification alone to date. Thus, we conducted a systematic review and meta-analysis comparing these two strategies through studies, assessing the effectiveness and safety of outcomes in a population with glaucoma. The protocol for this systematic review was registered in the PROSPERO International Prospective Register of Systematic Reviews (CRD42023482376). We systematically searched PubMed, Embase, and Web of Science from inception to December 2023. A random-effects model was used for all analyses due to heterogeneity. Review Manager 5.3 (Cochrane Centre, The Cochrane Collaboration, Denmark) was used for statistical analysis. Finally, nine studies were included in this comprehensive review and a total of 5389 eyes were analyzed in our study. In comparison to the ECP and phacoemulsification group, those receiving phacoemulsification alone showed better results in best-corrected visual acuity (MD 0.09; CI 95% 0.03 to 0.16; I²=0%), but worse outcomes in intraocular pressure (IOP) (MD -1.49; 95% CI -2.29 to -0.68; I²=29%) and use medications (MD -0.75; 95% CI -0.94 to -0.56; I²=0%) in the last visit. Complication rates, both general and serious, were significantly different between the groups, indicating the potential impact of combined procedures on patient outcomes. Thus, combining ECP with phacoemulsification for glaucoma treatment showed sustained IOP reduction and decreased medication dependence. However, higher complication rates suggest careful consideration of risks. More extensive research with larger trials and longer follow-ups is needed to validate findings and address limitations, providing valuable insights into this treatment approach.

[PMID: 38255291 PMCID: PMC10813537 DOI: 10.3390/biomedicines12010186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 12/29/2023] [Accepted: 01/10/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND this study aimed to assess the effectiveness and safety of phaco-endocyclophotocoagulation (phaco-ECP) in patients with glaucoma over five consecutive years. METHODS Thirty-eight patients (38 eyes) with primary and secondary glaucoma were enrolled to undergo phaco-ECP (Endo Optiks URAM E2, Beaver-Visitec International, Waltham, MA, USA). The primary outcome measures were intraocular pressure (IOP) reduction, success rates, glaucoma medication use, and visual acuity after phaco-ECP. An IOP reduction of 20% compared to the baseline value without re-intervention was considered a successful treatment. Complete success was defined as a cessation of antiglaucoma medications. Secondary outcome measures included intraoperative and postoperative complications. Measurements were performed preoperatively and in the first week and 1, 3, 6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months postoperatively. RESULTS The mean ± SD values of IOP preoperatively, at 12, 24, 36, 48, and 60 months postoperatively were 22.6 ± 6.7 mmHg, 15.9 ± 3.9 mmHg (p < 0.001), 15.9 ± 2.9 mmHg (p < 0.001), 15.6 ± 2.7 mmHg (p < 0.001), 15.5 ± 3.8 mmHg (p < 0.001), and 15.2 ± 2.6 mmHg (p < 0.001), respectively. The mean IOP at the last follow-up was reduced by 32.7%. The decrease in the number of antiglaucoma medications was statistically significant at each follow-up visit compared to the baseline. The qualified success rate was 40.6%. All patients at the 60-month follow-up visit required the use of antiglaucoma medications-none of the patients achieved complete success. During the follow-up period, nine patients (28.3%) that required retreatment due to nonachievement of the target IOP were considered failures. Six patients (15.8%) were lost from the follow-up. A total of 23 patients were evaluated 60 months after their phaco-ECP. Complications directly associated with the procedure, such as corneal edema (25.6%), IOP spikes (20.5%), IOL dislocation (2.6%), and uveitis (12.8%), were observed in our patients. Hypotony was not observed in any of our patients. CONCLUSIONS The phaco-ECP procedure was effective, well-tolerated, and safe for reducing IOP in glaucoma patients with cataracts over a long-term follow-up. Randomized, larger-scale studies are required to validate the results obtained.

Abstract
The development of minimally invasive glaucoma surgeries (MIGSs) was intended to provide safe and modestly efficacious modalities for early intervention of mild-to-moderate glaucoma, with minimal trauma and rapid recovery. They were mainly ab interno procedures that reduce intraocular pressure by facilitating the aqueous outflow by bypassing the trabecular meshwork resistance, reinforcing the uveoscleral flow via the supraciliary space, and reducing aqueous production by the ciliary body. While the cumulating evidence helps shape the role of the available MIGS, the exponential new development and advancement in this field has expanded the territory of MIGS. Apart from developing subconjunctival MIGS filtration devices (Xen gel stent and PRESERFLO MicroShunt), there is a tendency to revisit the "traditional" MIGS for alternative use and to modify the procedures with consideration of the fundamental aqueous outflow physiology. Combined MIGS has also been suggested, based on the theory that their different mechanisms may provide additive or synergistic effects. The advancement of laser procedures is also promising and could supplement unmet needs along the glaucoma treatment algorithm. This review examines the broad array of MIGS, updates the recent findings, discusses their potential alternative applications, and explores future challenges.

Transscleral vs endoscopic cyclophotocoagulation: safety and efficacy when combined with phacoemulsification. BMC Ophthalmol 2023; 23:129. [PMID: 36997879 PMCID: PMC10061713 DOI: 10.1186/s12886-023-02877-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Accepted: 03/22/2023] [Indexed: 04/01/2023] Open
Abstract
PURPOSE To compare the effectiveness and safety of phacoemulsification combined with endoscopic cyclophotocoagulation (phaco/ECP), phacoemulsification combined with MicroPulse transscleral cyclophotocoagulation (phaco/MP-TSCPC), and phacoemulsification alone (phaco) in the treatment of coexisting cataract and glaucoma. METHODS Retrospective cohort study of consecutive cases at Massachusetts Eye & Ear. The main outcome measures were the cumulative probabilities of failure between the phaco/ECP group, phaco/MP-TSCPC group, and the phaco alone group with failure defined as reaching NLP vision at any point postoperatively, undergoing additional glaucoma surgery, or the inability to maintain ≥ 20% IOP reduction from baseline with IOP between 5-18 mmHg while maintaining ≤ baseline medications. Additional outcome measures included changes in average IOP, number of glaucoma medications, and complication rates. RESULTS Sixty-four eyes from 64 patients (25 phaco/ECP, 20 phaco/MPTSCPC, 19 phaco alone) were included in this study. The groups did not differ in age (mean 71.04 ± 6.7 years) or length of follow-up time. Baseline IOPs were significantly different between groups (15.78 ± 4.7 mmHg phaco/ECP, 18.37 ± 4.6 mmHg phaco/MP-TSCPC, 14.30 ± 4.2 mmHg phaco alone, p = 0.02). Primary open-angle glaucoma was the most common type of glaucoma in the phaco alone (42%) and phaco/ECP (48%) groups while mixed-mechanism glaucoma was the most common type in the phaco/MP-TSCPC group (40%). Surgical failure was less likely in eyes in the phaco/MP-TSCPC (3.40 times, p = 0.005) and phaco/ECP (1.40 times, p = 0.044) groups compared to phaco alone based on the Kaplan-Meier survival criteria. These differences maintained statistical significance when differences in preoperative IOP were taken into account using the Cox PH model (p = 0.011 and p = 0.004, respectively). Additionally, surgical failure was 1.98 times less likely following phaco/MP-TSCPC compared to phaco/ECP (p = 0.038). This difference only approached significance once differences in preoperative IOP were accounted for (p = 0.052). There was no significant difference in IOP reduction at 1 year between groups. Mean IOP reductions at 1 year were 3.07 ± 5.3 mmHg from a baseline of 15.78 ± 4.7 in the phaco/ECP group, 6.0 ± 4.3 mmHg from a baseline of 18.37 ± 4.6 in the phaco/MP-TSCPC group and 1.0 ± 1.6 from a baseline of 14.30 ± 4.2 mmHg in the phaco alone group. There were no differences in complication rates among the three groups. CONCLUSIONS Both Phaco/MP-TSCPC and phaco/ECP appear to provide superior efficacy for IOP control when compared to phaco alone. All three procedures had similar safety profiles.

Abstract
BACKGROUND Long-term comparative data of phacoemulsification combined with endoscopic cyclophotocoagulation (phaco-ECP) versus phacoemulsification (phaco) alone in dogs are rare. OBJECTIVES To investigate the effects of ECP on postoperative intraocular pressure (IOP) and complications after phaco in dogs with normal IOP. METHODS Medical records of IOP, conjunctival hyperemia, corneal edema, aqueous flare, posterior synechia, intraocular fibrin, and posterior capsule opacification (PCO) formation in 15 canine eyes that underwent phaco-ECP and 36 eyes that underwent phaco alone were evaluated retrospectively. ECP was applied when either the iridocorneal angle or the ciliary cleft was narrow or closed. RESULTS The IOP of the phaco-ECP group persisted within the normal range postoperatively. The phaco-ECP group had a shorter period of dorzolamide use than did the phaco group. PCO was formed earlier in the phaco-ECP group than in the phaco group. The phaco-ECP group showed more severe corneal edema than the phaco group at every follow-up visit. Posterior synechia was more severe in the phaco-ECP group than in the phaco group from two weeks until the last follow-up. CONCLUSIONS Although ECP might cause more postoperative complications such as corneal edema and posterior synechia, it could effectively reduce the incidence of IOP increase after phaco in dogs with a high risk of postoperative glaucoma.

The place of endoscopic laser cyclodestruction in the system of microinvasive glaucoma surgery. OPHTHALMOLOGY JOURNAL 2022.

Abstract
Glaucoma is one of the leading causes of irreversible blindness in the world. Reducing intraocular pressure is the only way to slow down the progression of glaucomatous optic neuropathy. Minimally invasive glaucoma surgery aims to provide a safer way of reduction of intraocular pressure than traditional methods, and at the same time it is capable to reduce dependence on antihypertensive therapy. Cyclodestructive high-precision method of reducing the production of aquоeus humor occupies a confident position among modern minimally invasive glaucoma surgery methods. The data obtained as a result of studying the literature confirm our idea on the endoscopic laser cyclodestruction method as a minimally invasive, safe, reliable antiglaucomatous component of the combined surgical treatment of cataract and glaucoma.

Abstract
Background To propose that possible alteration or damage to the ciliary zonules during uncomplicated endoscopic cyclophotocoagulation (ECP) can cause complications in subsequent filtration surgery. Case presentation We present two cases with uncomplicated primary combined phacoemulsification and ECP that underwent subsequent trabeculectomy. Both cases were complicated with vitreous prolapse during the trabeculectomy procedure. We review the anatomy of the ciliary zonules and their spatial relationship with the ciliary processes targeted during ECP and propose an association between ECP, zonular damage and complications in subsequent trabeculectomy such as vitreous prolapse. Conclusions Damage to ciliary zonules during ECP may not manifest until subsequent glaucoma filtration surgery. In patients who received prior ECP, we may consider taking preventative measures to avoid associated complications such as vitreous prolapse. Patients with known risk factors for weak zonules may consider choosing alternative intraocular pressure-lowering means.

Abstract
PURPOSE To compare combined phacoemulsification plus endoscopic cyclophotocoagulation (ECP) versus phacoemulsification alone in primary angle-closure glaucoma (PACG) with coexisting cataract. DESIGN Prospective randomized controlled clinical trial-a pilot study. PARTICIPANTS Forty-eight PACG eyes of 48 patients with coexisting cataract. INTERVENTION Recruited patients were randomized into undergoing phacoemulsification plus ECP or phacoemulsification alone. After surgery, patients were followed up every 3 months for 2 years. MAIN OUTCOME MEASURES Intraocular pressure (IOP) and requirement for topical glaucoma drugs. RESULTS Twenty-seven PACG eyes were randomized to receive combined phacoemulsification plus ECP, and 21 PACG eyes underwent phacoemulsification alone. There was no statistically significant difference in mean preoperative IOP between combined phacoemulsification plus ECP and phacoemulsification groups (20.0 mmHg vs. 20.7 mmHg; P = 0.71). Phacoemulsification plus ECP resulted in lower mean postoperative IOP than phacoemulsification alone at all follow-up visits, but the differences only reached statistical significance at 1 month (P = 0.01), 12 months (P = 0.01), and 24 months (P = 0.04) postoperatively. There was no statistically significant difference in mean preoperative number of topical glaucoma drugs between combined phacoemulsification plus ECP and phacoemulsification groups (3.3 vs 3.1, P = 0.71). Combined phacoemulsification plus ECP resulted in lower glaucoma drug requirement than phacoemulsification alone at all follow-up visits, but the differences did not reach statistical significance at any time points postoperatively (P ≥ 0.05). Both groups were comparable in visual improvement, complication rate, need for additional surgical intervention, and visual field changes. CONCLUSIONS Combined phacoemulsification plus ECP is noninferior to phacoemulsification alone in controlling IOP in PACG eyes with cataract. Combined phacoemulsification plus ECP resulted in lower mean IOP and glaucoma drug requirement than phacoemulsification alone at all follow-up visits in this pilot study, but the differences did not reach statistical significance at the majority of time points. A large-scale randomized controlled trial is in progress to evaluate these differences.

Safety and Efficacy of Isolated Endoscopic Cyclophotocoagulation in Pseudophakic Patients with Primary Open-Angle Glaucoma-12-Month Follow-Up. J Clin Med 2021; 10:jcm10184212. [PMID: 34575323 PMCID: PMC8468505 DOI: 10.3390/jcm10184212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 09/13/2021] [Accepted: 09/15/2021] [Indexed: 11/17/2022] Open
Abstract
Background: We evaluated the safety and efficacy of endoscopic cyclophotocoagulation (ECP) for eyes with primary open-angle glaucoma (POAG). Methods: We included a total of 104 pseudophakic eyes treated with ECP. Visual acuity and intraocular pressure (IOP, mmHg) measurements were evaluated preoperatively and on days 1 and 7 and 2 and 12 months postoperatively. IOP ≤ 15 or ≥30% reduction from baseline were defined as therapeutic success. Results: The mean baseline IOP was 23.89 ± 8.63, and it decreased significantly at the day 1 (16.25 ± 7.32, p < 0.0001), day 7 (17.81 ± 6.37, p < 0.0001), 2nd month (17.77 ± 8.54, p < 0.0001) and 12th month (16.42 ± 7.05, p < 0.0001) follow-up visits. Therapeutic success was achieved in 55 (61.80%) eyes at the 12-month follow-up. Patients with POAG duration longer than 10 years or those using alpha agonist eye drops had a lower rate of therapeutic success (odds ratio: 0.52, 95% CI = 0.32–0.85, p < 0.05 and odds ratio: 0.92, 95% CI = 0.55–0.95, p = 0.024, respectively). A longer disease course was associated with higher IOP values (Rs =+0.281; p = 0.024) postoperatively. The number of antiglaucoma medications decreased significantly from 2.55 ± 1.16 to 2.11 ± 1.14 (p = 0.003). The ECP complications included a minor IOP increase (9.37%), pupil irregularity (15.73%), and the presence of fibrin (3.29%). Conclusions: The ECP is an effective and safe option, especially in eyes with a shorter glaucoma course.

Endocyclophotocoagulation combined with phacoemulsification in surgically naive primary open-angle glaucoma: three-year results. Eye (Lond) 2021; 36:1890-1895. [PMID: 34526677 PMCID: PMC9499941 DOI: 10.1038/s41433-021-01734-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 07/20/2021] [Accepted: 07/29/2021] [Indexed: 11/08/2022] Open
Abstract
OBJECTIVE To assess the safety and efficacy of endocyclophotocoagulation with phacoemulsification (phaco-ECP) in surgically naive, primary open-angle glaucoma (POAG). METHODS A retrospective case series of patients undergoing phaco-ECP between 2007 and 2017 at a single centre in London, UK. The primary outcome was intraocular pressure (IOP). Secondary outcomes were visual acuity, visual field global indices, topical medications and surgical complications. Failure criteria were: (1) IOP > 21 mmHg or <20% reduction at two consecutive visits, (2) IOP <5 mmHg and (3) further IOP-lowering surgery. RESULTS Eighty-three eyes from 83 patients were eligible. Pre-operatively, mean IOP (±SD) was 18.4 ± 5.2 mmHg. The mean number of topical agents (±SD) was 2.7 ± 0.9. Mean IOP (±SD) significantly reduced to 14.3 ± 4.7 at 1 year, 14.1 ± 4.0 at 2 years and 13.6 ± 3.7 at 3 years (p < 0.0001). Topical medications were significantly reduced to 1.3 ± 1.2 at 1 year, 1.7 ± 1.2 at 2 years and 1.8 ± 1.3 at 3 years (p < 0.0001). Annual IOP 'survival' was 70%, 54% and 45% at year 1, 2 and 3, respectively. Complications included uveitis (6%), macular oedema (2%), IOP spikes (1%) and corneal decompensation (1%) with no episodes of hypotony or retinal detachment. One patient underwent filtration surgery within 3 years (1%). CONCLUSION Phaco-ECP facilitates significant IOP lowering and reduction of medication burden in surgically naive POAG requiring cataract extraction. The procedure is relatively safe and without the use of implants and their associated risks.

Long-term Surgical Outcomes of Phacoemulsification with Endoscopic Cyclophotocoagulation vs Phacoemulsification with Trabeculectomy and Mitomycin in Cataract and Glaucoma Patients. Clin Ophthalmol 2021; 15:3573-3580. [PMID: 34465978 PMCID: PMC8403082 DOI: 10.2147/opth.s320092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 07/20/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose To evaluate the long-term surgical outcomes of endoscopic cyclophotocoagulation (ECP) after four years follow-up in cataract and glaucoma patients that needed combined phacoemulsification and ECP (phaco-ECP) in comparison to combined phacoemulsification with trabeculectomy (phaco-trabeculectomy) with mitomycin C (MMC). Patients and Methods Retrospective case–control study of 34 patients (34 eyes) with glaucoma who underwent phaco-ECP compared with phaco-trabeculectomy in tertiary eye specialist hospital in Saudi Arabia from 2010 to 2012. Participants were enrolled in two groups; ECP and trabeculectomy with MMC when combined with phacoemulsification. Success is defined as complete success when the IOP ≤21 mmHg without medication, qualified success when the IOP ≤21 mmHg with aid of topical medication. Results Mean IOP decreased from 25.76 SD ±8.227 to 15.24 SD ±7.049 at last visit in phaco-trabeculectomy group and from 21.47 SD ±4.215 to 12.88 SD ±3.480 in phaco-ECP group. Mean medication use reduced from 2.89 SD ±0.3 preoperatively to 1.50 SD ±1.1 postoperatively (P<0.001) in phaco-trabeculectomy group. It reduced in phaco-ECP group from 2.24 SD ±0.8 preoperatively to 2.00 SD ±0.9 postoperatively, 35.3% of phaco-trabeculectomy group developed vision-threatening complications while 0% in phaco-ECP group (P<0.001), 29.4% in phaco-trabeculectomy group required second surgical intervention compared to 17.6% in phaco-ECP group. In phaco-trabeculectomy group, 29.4% reached complete success, meanwhile in phaco-ECP group, 64.7% reached qualified success (P=0.026). Conclusion ECP illustrates significant reduction of IOP and less postoperative complications if associated with phacoemulsification. Furthermore, it is safe and effective as a primary procedure alternative to combined cataract and trabeculectomy surgery for glaucoma patients having cataract and requiring surgical intervention.

An update on continuous-wave cyclophotocoagulation (CW-CPC) and micropulse transscleral laser treatment (MP-TLT) for adult and paediatric refractory glaucoma. Acta Ophthalmol 2021; 99:e621-e653. [PMID: 33222409 DOI: 10.1111/aos.14661] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 09/06/2020] [Accepted: 10/11/2020] [Indexed: 12/12/2022]
Abstract
PURPOSE Continuous-wave cyclophotocoagulation (CW-CPC) is often preferred to medical and surgical treatments for managing refractory glaucoma. This review summarizes diode CW-CPC indications, history, histopathology, methods, efficacy and safety. It also provides an overview of the latest data available on micropulse transscleral laser treatment (MP-TLT) that uses repetitive micropulses of diode laser energy in an off-and-on cyclical fashion. METHODS A literature review was conducted on transscleral CW-CPC (CW-TSCPC), endoscopic CPC (ECP) and MP-TLT. Relevant series of adult and paediatric patients were included for assessing the procedures. RESULTS Regarding CW-TCPC, highly variable success rates are reported in the literature, depending on the definition of success, type of underlying glaucoma, energy settings, follow-up duration and retreatment rates. CW-CPC often needs to be repeated, especially in paediatric patients. CW-CPC exposes to risks of inflammation and chronic ocular hypotony or phthisis with irreversible visual loss. CW-TSCPC has mainly been used in very severe forms of glaucoma, in painful eyes with limited visual potential or after filtering surgery failure. Published data on ECP are more limited but overall good success rates have been reported. Through the direct visualization of the targeted ciliary body in anatomically abnormal eyes, ECP is the preferred surgical procedure in paediatric refractory glaucoma. Complication rates are relatively low after ECP; however, large studies with long-term follow-up are needed. ECP may be used in difficult, refractory cases, but it is often used earlier when combined with cataract surgery. Despite limited data on the exact mechanism of action of MP-TLT and a lack of standardization of laser settings, the first data from heterogeneous case series shows that it has a similar efficacy and a better safety profile compared to CW-TSCPC in the medium term. CONCLUSION Although they may lead to sight-threatening complications, both CW-TSCPC and ECP seem effective. ECP appears to be superior to CW-TSCPC in paediatric refractory glaucoma. Unlike ECP combined with cataract surgery, evidence supporting a wider use of CW-TSCPC and MP-TLT in earlier stages of neuropathy is lacking. While it now appears that the safety profile of MP-TLT is superior to that of CW-CPC, robust prospective comparative studies including homogeneous and well-defined cohorts of patients are still needed to confirm an at least comparable efficacy in the long term.

Abstract
PURPOSE To examine how indications, patient characteristics, and outcomes differ between anterior and posterior approaches of endoscopic cyclophotocoagulation (ECP) in the treatment of glaucoma. METHODS This is a retrospective chart review of 9 anterior and 20 posterior ECP cases (n = 29). RESULTS Posterior ECP cases were typically associated with a dramatic increase in intraocular pressure (IOP), whereas the anterior ECP was associated with chronically elevated pressures. The initial IOPs in mm Hg of posterior ECP cases (26.8 non-NVG; 35.2 NVG) were much greater than anterior ECP cases (17.8), and a greater overall reduction in IOP was observed in the posterior versus anterior ECP cases (10.3 posterior non-NVG; 21.3 posterior NVG; 3.6 anterior, P < .001). With procedural success defined as 6-month post-operative IOP falling within normal ranges and a decrease in either IOP or number of prescribed glaucoma medications, the success rate of ECP was 92% for posterior NVG, 89% for anterior and 75% for posterior non-NVG cases (P = .34), similar to the previous literature. Of the four unsuccessful cases, two resulted in a normal IOP but lacked a drop in pressure or reduction in medication burden, one resulted in a 6-point drop in IOP but remained at 23 mm Hg, and one resulted in phthisis bulbi (3%) from an initial pressure above 40 mm Hg. CONCLUSION Endoscopic cyclophotocoagulation is an effective and safe procedure for severe glaucoma cases from both an anterior and posterior approach. Ophthalmologists should consider this procedure as part of their glaucoma treatment arsenal.

Abstract
Nowadays glaucoma is one of the leading causes of irreversible blindness worldwide. The main goal in preservation of vision in glaucoma patients is reducing intraocular pressure (IOP), which is considered the main controlled risk factor for progression of glaucomatous optic neuropathy. The article discusses the effectiveness and safety of various transscleral laser technologies in the treatment of glaucoma. Modern transscleral laser technologies that affect the uveoscleral drainage and scleral hydro-permeability are less traumatic and more gentle making them promising in the treatment of patients with early stages of glaucoma, and not only in terminal glaucoma with pain syndrome resistant to conventional treatment ("last resort surgery").

BMC Ophthalmol 2020; 20:406. [PMID: 33036581 PMCID: PMC7545548 DOI: 10.1186/s12886-020-01643-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Accepted: 09/10/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Glaucoma surgery have been developed to lower intraocular pressure in a less invasive manner than traditional glaucoma surgery. The purpose of this article is to determine the outcome of using combined phacoemulsification technique, ab-interno trabeculectomy dual blade and endoscopic cyclophotocoagulation (ECP) surgeries in patients with primary open angle glaucoma. METHODS A retrospective case series was performed on 27 consecutive eyes with both primary open-angle glaucoma (POAG) and cataract; each eye was treated with combined phacoemulsification, ab-interno trabeculectomy-Kahook Dual Blade and Endocyclophotocoagulation at Instituto de ojos Oftalmosalud, Lima, Peru, between April 2017 and May 2017. INCLUSION CRITERIA 1) Patients with uncontrolled mild to advanced POAG (according to Glaucoma Grading Scale HODAPP) 2) cataract condition 3) treatment with two or more glaucoma medications due to rapid progression in the visual fields (at least two in a short period of time). Intraocular pressure (IOP), best corrected visual acuity (BCVA) logMAR and number of glaucoma medications were recorded prior to the study, at day 1, week 1, and 1,3,6 and 9 months after surgery. Primary outcome measure was surgical success defined in terms of IOP < 14 mmHg either with no medications (complete success) or with medications (qualified success). RESULTS A total of 27 eyes from 27 patients were included. The mean basal IOP was 17.0 ± 3.7 mmHg and postoperatively was 11.6 ± 1.9 mmHg and 11.4 ± 1.8 mmHg (P < 0.001) at 6 and 9 months respectively. Glaucoma medications decreased from 1.9 ± 1.4 to 0.56 ± 1.05 at 9 month follow-ups (P < 0.001). Preoperative best corrected visual acuity (BCVA) showed and improvement from 0.4 ± 0.4 LogMAR to 0.2 ± 0.4 logMAR at 9 months. The main complication was blood reflux intra-operatively (66.7%), which resolved without re-operation. The mean IOP was reduced by 32.9% from baseline and the surgical success was 92,6%, (complete success 70,3% and qualified success 29,6%) at 9 months. CONCLUSIONS In patients with POAG, combined treatment with phacoemulsification, ab-interno trabeculectomy and endoscopic cyclophotocoagulation effectively reduced IOP and glaucoma medication dependence.

Abstract
AIM To investigate the efficacy and safety of combined phacoemulsification and goniosynechialysis with or without endoscopic cyclophotocoagulation (PGE group and PG group) for the treatment of patients with coexisting primary angle-closure glaucoma (PACG) and cataracts. METHODS The clinical data of patients with PACG and cataract were retrospectively reviewed. There was a total of 88 eyes in the study and were divided into two groups, 42 eyes in PGE group and 46 eyes in PG group. Surgery success cumulative survival, preoperative and postoperative intraocular pressure (IOP), number of IOP-lowering medications, best corrected visual acuity (BCVA) in the two groups were observed for more than 12mo and compared within each group and between two groups. RESULTS The mean IOP in PGE group declined from 24.9 mm Hg preoperatively to 14.1 mm Hg at the first month after operation (P<0.001) and at the last visit 16.2 mm Hg (P<0.001). Meanwhile PG group also showed significant decrease, from 24.1 mm Hg preoperatively to 13.0 mm Hg at 1mo after operation (P<0.001) and 15.3 mm Hg at the last visit (P=0.004). The mean medications reliance reduced in both groups, in PGE group was reduced from 1.62 preoperatively to 0.13 at the last visit (P<0.001), in PG group from 0.87 to 0.10 (P<0.001). At the last visit, BCVA increased from 0.21 to 0.60 in PGE group (P<0.001) and from 0.24 to 0.67 in PG group (P<0.001). The success rate of PGE group at 1mo was 95.2%, then decreased to 70.7% at the last visit, whereas in PG group, the success rate at 1mo was 100%, at the last visit was 73.4%. CONCLUSION PGE shows promise for PACG patients with cataracts to reduce IOP, lighten the medication burden and improve visual acuity, and PG still has its value in specific patients.

Abstract
PURPOSE To characterize the use of laser and incisional glaucoma surgeries among Medicare beneficiaries from 2008 through 2016 and to compare the use of these surgeries by glaucoma subspecialists versus nonsubspecialists. DESIGN Retrospective, observational analysis. PARTICIPANTS Medicare beneficiaries (n = 1 468 035) undergoing ≥1 laser or incisional glaucoma surgery procedure during 2008 through 2016. METHODS Claims data from a 20% sample of enrollees in fee-for-service Medicare throughout the United States were analyzed to identify all laser and incisional glaucoma surgeries performed from 2008 through 2016. We assessed use of traditional incisional glaucoma surgery techniques (trabeculectomy and glaucoma drainage implant [GDI] procedure) and microinvasive glaucoma surgery (MIGS). Enrollee and procedure counts were multiplied by 5 to estimate use throughout all of Medicare. Linear regression was used to compare trends in use of glaucoma surgeries between ophthalmologists who could be characterized as glaucoma subspecialists versus nonsubspecialists. MAIN OUTCOME MEASURES Numbers of laser and incisional glaucoma surgeries performed overall and stratified by glaucoma subspecialist status. RESULTS The number of Medicare beneficiaries undergoing any glaucoma therapeutic procedure increased by 10.6%, from 218 375 in 2008 to 241 565 in 2016. The total number of traditional incisional glaucoma surgeries decreased by 11.7%, from 37 225 to 32 885 (P = 0.02). The total number of MIGS procedures increased by 426% from 13 705 in 2012 (the first year MIGS codes were available) to 58 345 in 2016 (P = 0.001). Throughout the study period, glaucoma subspecialists performed most of the trabeculectomies (76.7% in 2008, 83.1% in 2016) and GDI procedures (77.7% in 2008, 80.6% in 2016). Many MIGS procedures were performed by nonsubspecialists. The proportions of endocyclophotocoagulations, iStent (Glaukos; San Clemente, CA) insertions, goniotomies, and canaloplasties performed by glaucoma subspecialists in 2016 were 22.0%, 25.2%, 56.9%, and 62.8%, respectively. CONCLUSIONS From 2008 through 2016, a large shift in practice from traditional incisional glaucoma surgeries to MIGS procedures was observed. Although glaucoma subspecialists continue to perform most traditional incisional glaucoma surgeries, many MIGS procedures are performed by nonsubspecialists. These results highlight the importance of training residents in performing MIGS procedures and managing these patients perioperatively. Future studies should explore the impact of this shift in care on outcomes and costs.

Abstract
PRéCIS:: This retrospective study found that combined phacoemulsification and endocyclophotocoagulation reduced intraocular pressure (IOP) to a greater degree in angle-closure glaucoma versus open-angle glaucoma and was effective for all stages of glaucoma. PURPOSE Endocyclophotocoagulation (ECP) laser treatment of the ciliary processes is believed to decrease IOP by reducing aqueous production. Anecdotal experience in angle-closure glaucoma suggests that it may also lower IOP by opening the drainage angle to promote aqueous outflow. This study sought to evaluate combined phacoemulsification and ECP (phaco/ECP) in eyes with different types and stages of glaucoma. PATIENTS AND METHODS A Retrospective chart review of eyes that underwent phaco/ECP between October 2010 and December 2016 at one institution was conducted. RESULTS In 63 eyes of 63 patients with an average of 3.0±1.7 years of follow-up, the 22 eyes with chronic angle-closure glaucoma (CACG) had greater IOP reduction and medication reduction than the 41 eyes with primary open-angle glaucoma at both 1 year (6.4 vs. 2.1 mm Hg, P=0.01; 0.9 vs. 0.2 medications, P=0.04) and final follow-up (6.2 vs. 2.4 mm Hg, P=0.02; 0.9 vs. 0.3 medications, P=0.05). There was no difference in IOP reduction or medication reduction for eyes with mild, moderate, or advanced glaucoma at both 1 year (3.5, 3.9, 0.5 mm Hg, respectively, P=0.18; 0.3, 0.6, 0.4 medications, P=0.58) and final follow-up (3.3, 4.8, 0.7 mm Hg, P=0.11; 0.1, 0.8, 0.4 medications, P=0.14). CONCLUSIONS Eyes with CACG were more responsive to phaco/ECP in terms of IOP and medication reduction compared with eyes with primary open-angle glaucoma. This finding could be partially or entirely due to concurrent cataract extraction and greater CACG preoperative IOP. Phaco/ECP was effective in all stages of glaucoma.

Abstract
AIM Comparing outcomes after combined phacoemulsification, two iStents insertion and endocyclophotocoagulation (ECP) versus phacoemulsification-iStents alone. METHODS This is a longitudinal retrospective 12 months study in eyes with ocular hypertension or early-to-moderate open angle glaucoma. Level of disease, intraocular pressure (IOP) and tolerance of glaucoma medication were considered before planning surgery. Best-corrected visual acuity (BCVA-logMAR), IOP (mm Hg), number of medications were assessed at baseline, week 1, week 5, month 3, 6, 12 postop. MAIN OUTCOME percentage (%) in IOP reduction at 12 months vs medicated baseline. SECONDARY OUTCOMES absolute values of IOP/medication reduction, BCVA and postop complications. RESULTS The ICE2 (two iStents-cataract extraction-ECP) group included 63 eyes and Phaco-iStent group included 46 eyes. Baseline IOP was higher in the ICE2 than phaco-iStent group (19.97±4.31 mm Hg vs 17.63±3.86 mm Hg, p=0.004) and mean deviation was lower (-7.20±2.58 dB vs -4.94±4.51 dB, p=0.037). Number of medications were comparable at baseline: 2.22±1.06 (ICE2) vs 2.07±1.02 (phaco-iStent), p=0.442. At month 12 postop, IOP in the ICE2 group decreased 35% from baseline vs 21% in the phaco-iStent group (p=0.03); absolute IOP reduction was significantly lower than baseline in each group (p<0.001), yet final IOP was lower in the ICE2 group than phaco-iStent group (13.05±2.18 mm Hg vs 14.09±1.86 mm Hg, p=0.01). Similar results were found for glaucoma medication (1.24±1.05 in ICE2 group vs 1.39±1.03 in phaco-iStent group, p=0.01). Final BCVA was 0.11±0.18 (phaco-iStent group) vs 0.08±0.08 (ICE2 group), p=0.309. Safety outcomes were comparable between groups. CONCLUSION ICE2 procedure offers better results in IOP/medication reduction at 12 months than phacoemulsification-iStents alone.

Abstract
Purpose: To compare surgical outcomes of patients after phacoemulsification with goniosynechialysis (phaco/GSL) versus phaco with GSL and endocyclophotocoagulation (phaco/GSL/ECP) in patients with chronic angle closure glaucoma (CACG) through 12-month follow-up. Methods: A retrospective, nonrandomized, comparative case series was performed. Patients with CACG who underwent phaco in combination with either GSL alone (group 1) or GSL with ECP with intracameral injection of kenalog (group 2) from 2011 to 2018 were included. Group 1 included 6 eyes of 6 patients and group 2 included 11 eyes of 10 patients. All surgeries were performed by a single surgeon (RSA). Primary outcome measures included changes in intraocular pressure (IOP), visual acuity (VA), failure based on IOP (>18 or <6 mmHg at 1 year), and secondary operative procedures and complication rates. Data were analyzed using a paired two-tailed T-test. Results: The mean preoperative IOP decreased from 23.5 ± 11.2 to 14.2 ± 2.4 mmHg (P < 0.0073) in group 1 and 24.4 ± 8.2 to 14.5 ± 2.7 mmHg (P < 0.0001) in group 2. The mean % IOP reduction was 33.7% in group 1 and 34.2% in group 2. The mean improvement in VA (logMAR units) was 0.24 (P = 0.085) in group 1 and 0.13 (P = 0.657) in group 2. The mean number of topical meds decreased from 2.50 ± 1.76 to 1.80 ± 1.64 in group 1 (P = 0.513) and from 2.82 ± 1.25 to 1.17 ± 0.98 in group 2 (P = 0.014). Conclusion: Phaco/GSL and phaco/GSL/ECP both achieve a significant reduction in IOP without the complications associated with traditional glaucoma filtration surgeries.

Abstract
Purpose: This study aimed to investigate the efficacy of cyclophotocoagulation with an illuminated laser probe under a noncontact wide-angle retinoscope in treating refractory glaucoma. Methods: Eleven patients (11 eyes) with refractory neovascular glaucoma were treated with ciliary body photocoagulation. Preoperative and postoperative corrected visual acuity, intraocular pressure (IOP), ophthalmofundoscopy, B-ultrasound and ultrasound biomicroscopy, optical coherence tomography, and fundus fluorescein angiography were performed. Results: Preoperative IOP ranged from 45 to 58 mmHg (mean 51.9 mmHg). At postoperative 1, 3, and 6 months, the IOPs ranged between 16 and 33 mmHg (mean 27.1 mmHg), 14–28 mmHg (mean 20.6 mmHg), and 14–28 mmHg (mean 18.5 mmHg), respectively. IOP at the last follow-up (range 7–12 months) was 15–24 mmHg (mean 18.8 mmHg). An average of 63.8% decrease in postoperative IOP was found in these patients with no associated complications. The postoperative fibrotic exudate, anterior chamber hyphema, and exudative choroidal detachment were all well-managed and resolved. No patients experienced intraocular lens deviation or dislocation, hypotonia oculi, atrophy of eyeball, retinal detachment, endophthalmitis, or sympathetic ophthalmia. Conclusion: Cyclophotocoagulation with an illuminated laser probe under a noncontact wide-angle retinoscope is a safe and effective technique for the treatment of neovascular glaucoma.

Abstract
The aim of this study was to evaluate the outcomes of combined endocyclophotocoagulation (ECP) and phacoemulsification regarding vision, refraction, intraocular pressure (IOP), medication dependence, and complications in patients of African descent. A retrospective chart review was performed including all cases of ECP combined with phacoemulsification from October 2015 to March 2017. Exclusion criteria consisted of patients who were not of African descent and patients with <1 month follow-up. IOP was the primary outcome. Thirty-two eyes of 29 patients were included in the study. Mean ± standard deviation (SD) of IOP decreased from 17.30 ± 6.30 mmHg preoperatively to 15.88 ± 4.23 mmHg at the last postoperative visit (P = 0.301). In 2 of eight patients who did not demonstrate a difference in pre- and postoperative IOP changes, all IOP lowering medications were stopped. The mean ± SD of follow-up was 5.05 ± 4.08 months with a range of 1 to 18 months. The mean ± SD number of medications used for each patient for IOP control decreased from 2.59 ± 1.01 preoperatively to 1.97 ±1.38 (P = 0.045). Average visual acuity improved from 20/50 preoperatively to 20/25 (P = 0.002). Postoperative complication rate was low. ECP combined with phacoemulsification was effective to decrease IOP lowering medication dependence in patients of African descent. We found that combined ECP and phacoemulsification can lead to a significantly decreased dependence on IOP lowering drops, with some patients demonstrating complete independence from drops following surgery. Although there was not a significant decrease in IOP postoperatively when analyzed collectively, larger studies might to find such an association. Combined ECP and phacoemulsification has been shown to be a safe combination in patients with refractive glaucoma and may be considered if a patient desire less dependence on IOP lowering drops once other first-line methods have failed, or as a bridge between conservative and more definitive surgical treatment.

Abstract
The first surgical modalities to reduce aqueous humor production by damaging the ciliary body date back to the early twentieth century. Until recently, however, cyclodestructive procedures (e.g., cyclocryotherapy and transscleral diode laser photocoagulation) have been reserved as last option procedures in refractory glaucoma patients with poor visual potential. Emerging technologic innovation has led to the development of promising, safer and less destructive techniques, such as micropulse diode cyclophotocoagulation, endoscopic cyclophotocoagulation and ultrasound cyclodestruction. Consequently, an emerging paradigm shift is under way with the selection of these surgical options in eyes with less severe glaucoma and good visual potential. Although existing evidence has not, as yet, adequately defined the role and value of these procedures, their emergence is a welcome expansion of available options for patients with moderate-to-severe glaucoma. This article reviews the pertinent evidence on both established and evolving cyclodestructive techniques and describes their growing role in the management of glaucoma.

Abstract
As cataract occurs frequently in patients with glaucoma, combining phacoemulsification and endoscopic cyclophotocoagulation has been gaining attention recently due to its minimally invasive nature. A variety of studies had evaluated the efficacy and safety of this procedure and had shown extremely promising results. This review article has shown here that combined phacoemulsification and endoscopic cyclophotocoagulation procedure could effectively reduce intraocular pressure in medically uncontrolled glaucoma patients while avoiding serious complications associated with traditional cyclophotocoagulation procedure and adverse effects related to filtering surgery such as trabeculectomy.

Abstract
PURPOSE To examine the efficacy and safety of combined phacoemulsification and endoscopic cyclophotocoagulation (phaco-ECP) compared to phacoemulsification alone in patients with primary open-angle glaucoma (POAG). METHODS We performed a retrospective notes review of 99 consecutive clinical records of patients with POAG from 2 London eye departments. A total of 69 patients who underwent phaco-ECP and 30 sex- and age-matched control patients who underwent cataract surgery alone were included. Data on intraocular pressure (IOP), visual acuity (VA), number of ocular hypotensive medications, and postoperative complications were collected over 12 months. The primary outcome measure was defined as an IOP within normal limits (<21 mm Hg) and at least a 20% reduction in IOP from baseline. RESULTS Mean IOP was significantly decreased in both groups after 1 year (p<0.001 from baseline). The success rate was significantly higher in the phaco-ECP group (69.6%) than in the phaco group (40%) after 1 year (p = 0.004). Reduction in mean IOP and number of medications was also greater in the phaco-ECP group after 1 year (IOP reduction: 4.5 ± 5.13 mm Hg vs 1.83 ± 3.61 mm Hg; p = 0.007; number of medications reduction: 0.73 ± 0.71 vs 0.23 ± 0.56; p = 0.001). Both groups achieved a similar improvement in VA. There was a higher incidence of minor and self-limiting complications in the phaco-ECP group (p<0.047). CONCLUSIONS Phaco-ECP resulted in a greater reduction in IOP and number of medications than phacoemulsification alone in POAG.

Abstract
PURPOSE To compare the refractive outcome of eyes that underwent phacoemulsification combined with endoscopic cyclophotocoagulation (phaco-ECP) with the eyes that underwent phacoemulsification alone. METHODS A retrospective case series review of 103 consecutive eyes that underwent phaco-ECP and 62 eyes that underwent phacoemulsification between January 2006 and August 2012 was conducted. Post-operative refractive outcomes were obtained by subjective refraction or autorefraction. Demographic data, best corrected visual acuity, intraocular pressure, number of glaucoma agents and mean deviation of the Humphrey visual field test (MD) were also analysed. RESULTS The total number of eyes included in the study was 62 eyes for the phaco-ECP group and 62 eyes for the control group who underwent phacoemulsification alone. More than 90% of eyes (n = 56) in phaco-ECP group achieved post-operative refraction within ±1 dioptre (D) of the target refraction. In the control group, 100% of eyes achieved post-operative refraction within ±1D of the target refraction. When comparing the difference between the target and the actual refractive outcome between the phaco-ECP and the control group, there was no statistically significant difference. CONCLUSIONS Refractive outcome after phaco-ECP is comparable to phacoemulsification alone. This study suggests that the intraocular lens power can be selected for cataract surgery alone and that ECP does not change the effective lens position significantly; therefore, no modification of biometry formulae is required. Phaco-ECP should be considered as an effective, safe and predictable surgical treatment option for glaucoma patients with co-existing cataract.

Abstract
Glaucoma is one of the most common causes of blindness worldwide, and its prevalence is increasing. The aim of the present review is to describe the current medical and surgical treatment trends in the management of open-angle glaucoma. There has been an increase in the availability of glaucoma medications and the use of laser trabeculoplasty over the past decade, with a subsequent decrease in invasive incisional surgery. In addition, a new class of glaucoma procedures, termed microinvasive glaucoma surgery, has emerged, which aims to fill the gap between conservative medical management and more invasive surgery.

Abstract
AIM To report on the efficacy of combined endoscopic cyclophotocoagulation (ECP) and phacoemulsification cataract extraction (PCE) with intraocular lens placement for reduction of intraocular pressure (IOP) and medication burden in glaucoma. METHODS A retrospective case review of 91 eyes (73 patients) with glaucoma and cataract that underwent combined PCE/ECP surgery was performed. Baseline demographic and ocular characteristics were recorded, as well as intraocular pressure, number of glaucoma medications, and visual acuity postoperatively with 12-month follow-up. Treatment failure was defined as less than 20% reduction in IOP from baseline on two consecutive visits (at 1, 3, 6, or 12mo postoperatively), IOP ≥21 mm Hg or ≤5 mm Hg on two consecutive visits, or additional glaucoma surgery performed within 12mo after PCE/ECP. RESULTS Overall, mean medicated IOP was reduced from 16.65 mm Hg at baseline to 13.38 mm Hg at 12mo (P<0.0001). Mean number of glaucoma medications was reduced from 1.88 medications at baseline to 1.48 medications at 12mo (P=0.0003). At 3mo postoperatively, the success rate was 73.6% (95%CI: 63.3, 81.5), 57.1% at 6mo (95% CI: 46.3, 66.6), and 49.7% at 12mo (95%CI: 38.9, 59.6). Patient demographic characteristics were not associated with treatment success. The only ocular characteristic associated with treatment success was a higher baseline IOP. CONCLUSION Combined PCE/ECP surgery is an effective surgical option for the reduction of IOP and medication burden in glaucoma patients. Patients with higher baseline IOP levels are most likely to benefit from this procedure.

Abstract
PURPOSE To evaluate changes in intraocular pressure (IOP), vision, and medications at least 1 year after phacoemulsification combined with endocyclophotocoagulation for advanced glaucoma and cataract. METHODS A retrospective chart review was conducted on patients with advanced glaucoma who underwent phacoemulsification combined with endocyclophotocoagulation at King Khaled Eye Specialist Hospital between 2005 and 2012. Data were collected on patient demographics, type of glaucoma, IOP over time, best-corrected visual acuity, number of glaucoma medications, comorbidities, and previous surgeries. Absolute success was defined as IOP≤15 mm Hg without medication and qualified success was IOP≤15 mm Hg with medications. Statistical significance was indicated by P<0.05. RESULTS The study sample comprised 104 eyes (104 patients). Mean follow-up was 17.3±1.8 months. Mean IOP decreased from 17±1.4 mm Hg preoperatively to 14.7±1.3 mm Hg at the last postoperative visit. Absolute success was achieved in 11.9% (95% confidence interval, 5.6-18.2) of the eyes. Qualified success was achieved in 72.3% (95% confidence interval, 63.5-81.0) of the eyes. Best-corrected visual acuity improved by ≥2 lines in 76 (73%) eyes. Eyes with primary open-angle glaucoma had the higher absolute and qualified success rates compared with primary angle-closure and pseudoexfoliation glaucoma (P>0.05). Only 48 (46%) patients required >3 medications for IOP control compared with 78 (75%) patients before surgery. CONCLUSIONS At ≥1 year postoperatively, the absolute success rate of treating advanced glaucoma by endocyclophotocoagulation and phacoemulsification was low. However, medication burden was reduced. Owing to the significant variation in the success rate based on the type of glaucoma, patients with advanced glaucoma should be carefully selected and counseled.

Abstract
Endoscopic Cyclophotocoagulation (ECP) is a glaucoma surgery designed to reduce the intraocular pressure (IOP) by partially ablating the ciliary processes to decrease aqueous humour production and secretion. The aim of this paper is to review the literature regarding the background, indications and results of the surgery. Although there are case reports of visually devastating complications, including persistent hypotony and phthisis, the use of ECP is often reported in eyes with advanced diseases. When compared with both trabeculectomy and aqueous shunt implantation, the visual outcomes were better with ECP while the IOP outcomes were very similar. The evidence supports ECP as a very effective surgical option in recalcitrant glaucoma while some evidence supports its safety for use as a primary procedure.

Abstract
In recent years, many new procedures and implants have been introduced as safer alternatives for the surgical treatment of glaucoma. The majority of these advances are implant-based with a goal of increased aqueous drainage to achieve lower intraocular pressure (IOP). In contrast, endoscopic cyclophotocoagulation (ECP) lowers IOP through aqueous suppression. Although ciliary body ablation is a well-established method of aqueous suppression, the novel endoscopic approach presents a significant evolution of this treatment with marked improvement in safety. The endoscope couples a light source, video imaging, and diode laser to achieve direct visualization of the ciliary processes during controlled laser application. The result is an efficient and safe procedure that can achieve a meaningful reduction in IOP and eliminate or reduce glaucoma medication use. From its initial use in refractory glaucoma, the indications for ECP have expanded broadly to include many forms of glaucoma across the spectrum of disease severity. The minimally-invasive nature of ECP allows for easy pairing with phacoemulsification in patients with coexisting cataract. In addition, the procedure avoids implant or device-related complications associated with newer surgical treatments. In this review, we illustrate the differences between ECP and traditional cyclophotocoagulation, then describe the instrumentation, patient selection, and technique for ECP. Finally, we summarize the available clinical evidence regarding the efficacy and safety of this procedure.

Abstract
PURPOSE OF REVIEW To review the current literature regarding the effectiveness and risks of new surgeries that can be combined with phacoemulsification in the management of cataract and glaucoma. RECENT FINDINGS Surgical options for concurrently managing cataract and glaucoma have expanded in recent years. Endoscopic cyclophotocoagulation, trabecular micro-bypass stent, ab interno trabeculectomy, and canaloplasty may be performed in conjunction with cataract extraction to provide additional intraocular pressure (IOP) reduction. Studies evaluating these new glaucoma procedures combined with phacoemulsification generally include retrospective case series without a comparison group. Because cataract surgery alone is associated with IOP reduction, the relative contribution of the glaucoma procedure in lowering IOP cannot be determined in these studies. Randomized clinical trials are needed to better evaluate the efficacy and safety of newer glaucoma procedures in combination with cataract surgery. SUMMARY The newer glaucoma procedures appear less effective than trabeculectomy, but they are associated with a lower risk of surgical complications.

Abstract
Trabeculectomy surgery has been shown to lower intraocular pressure and is the most commonly performed glaucoma procedure worldwide. However, giving a patient a 'bleb for life' is not without consequences and the failure of trabeculectomy to control IOP in the long term is well documented. In some instances, such as in patients with exfoliative glaucoma or primary angle closure glaucoma, cataract surgery alone can often lower IOP to acceptable levels. Cataract surgery in these instances can sometimes be combined with procedures such as goniosynechialysis or endoscopic cyclophotocoagulation which may provide additional IOP lowering. Such surgery has the distinct advantage of avoiding conjunctival incisions, so that subsequent trabeculectomy, if required, is more likely to be successful. In any case, it is preferable to perform trabeculectomy in a pseudophakic eye for several reasons. If trabeculectomy is performed in a phakic eye, patients should be warned that subsequent cataract is likely and if cataract surgery is performed it is preferable to wait at least a year or more after the trabeculectomy to reduce the risk of bleb failure. Combined phacotrabeculectomy should be reserved for end-stage glaucoma in most cases, in order to reduce the risk of 'wipe-out'.

Abstract
PURPOSE OF REVIEW This review highlights recently published studies on transscleral and endoscopic diode cyclophotocoagulation (TCP, ECP) and summarizes the treatment results and complications. RECENT FINDINGS Although both TCP and ECP are efficacious procedures for the treatment of refractory glaucoma, no consensus exists for optimum treatment protocol. TCP has mainly been used as a last-resort treatment for intractable glaucoma with very limited visual potential. Repeated treatment is often required. Serious complications include vision loss, hypotony, and phthisis. High treatment energy per session and underlying abnormality seem risk factors for these complications. Recent growing numbers of investigations are giving promising results for TCP as a primary surgery in eyes with good vision. Although ECP came later into clinical use for glaucoma treatment, it is becoming more accepted and no longer reserved for end-stage cases. ECP is most commonly performed in conjunction with cataract surgery and shows overall good success with relatively low complication rates. Serious complications include hypotony, phthisis, cystoid macular edema, and retinal detachment. SUMMARY Recent literatures suggest that both TCP and ECP are performed increasingly as the primary surgery for various types and stages of glaucoma. Both treatments are effective procedures, although potential for serious complications exists.

Abstract
BACKGROUND To examine the outcome and complications of combined phacoemulsification and endoscopic cyclophotocoagulation as surgical management of cataract and glaucoma. DESIGN Retrospective uncontrolled case series from the glaucoma unit, Western Eye Hospital, London, UK. PARTICIPANTS Sixty-three eyes from 59 patients with coexisting cataract and glaucoma. METHODS Patients underwent routine phacoemulsification followed by 270-360 degree endoscopic cyclophotocoagulation as a single procedure. MAIN OUTCOME MEASURES Intraocular pressure, number of intraocular pressure-lowering medications, logMAR visual acuity, recorded complications. RESULTS Baseline characteristics included mean age (77.3 ± 11.1 years), mean logMAR visual acuity (1.01 ± 0.98), mean intraocular pressure (21.13 ± 6.21 mmHg) and mean number of intraocular pressure-lowering medications, (2.71 ± 1.06). Twelve months after phacoemulsification and endoscopic cyclophotocoagulation, mean intraocular pressure had reduced to 16.09 ± 5.27 mmHg (P < 0.01), number of intraocular pressure-lowering medications reduced to 1.47 ± 1.30 (P < 0.01) and mean logMAR acuity improved to 0.33 ± 0.22 (P < 0.01). Success, defined as an intraocular pressure reduction > 20% with intraocular pressure 6-21 mmHg, was achieved in 55.5% of eyes at 12 months. Complications included fibrinous uveitis, elevated intraocular pressure, posterior vitreous detachment and induced astigmatism. CONCLUSION Phacoemulsification and endoscopic cyclophotocoagulation is both safe and effective as surgical management for cataract and glaucoma. Larger intraocular pressure reductions can be achieved in older patients and those with higher baseline intraocular pressure.
