[PMID: 37516402 DOI: 10.1016/j.ajo.2023.07.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 07/21/2023] [Accepted: 07/21/2023] [Indexed: 07/31/2023]
Abstract
PURPOSE To evaluate the outcomes of microcatheter-assisted trabeculotomy (MAT) in childhood glaucoma (primary congenital glaucoma [PCG], juvenile open-angle glaucoma [JOAG], and secondary childhood glaucoma [SCG]) after failed glaucoma surgery. DESIGN Retrospective interventional case series. METHODS Patients with childhood glaucoma who underwent MAT after failed glaucoma surgery with at least 12 months of follow-up were evaluated. Pre- and postoperative intraocular pressure (IOP) and the number of glaucoma medications were recorded and compared. Success was defined as an IOP ≤21 mm Hg with or without glaucoma medication. Analysis of variance was used to compare the glaucoma subgroups. RESULTS Forty-five eyes (42 patients) with a median follow-up period of 19 months were included. The median age at the time of MAT was 10 (range, 0.8-33) years. The mean number of previous surgeries was 1.3 ± 0.5. The IOP had significantly reduced from baseline in all PCG, JOAG, and SCG patients (27.9 ± 4.5 vs 16.3 ± 8.0 mm Hg, P = .001; and 30.8 ± 9.4 vs 13.5 ± 3.0 mm Hg, P < .001; and 31.5 ± 7.1 vs 16.5 ± 5.3 mm Hg, P = .001, respectively). Fewer glaucoma medications were needed after MAT in all 3 groups (each P < .001). At the last visit, the total success rates in PCG, JOAG, and SCG were 93.8%, 100%, and 88.9%, respectively. No severe complications were observed. CONCLUSION MAT can effectively manage PCG, JOAG, and SCG after failed surgeries, providing successful outcomes and no serious complications. Following failed glaucoma surgeries, MAT may offer these patients with childhood glaucoma an excellent opportunity to achieve IOP control.

Abstract
PURPOSE To compare the outcomes of the Aurolab aqueous drainage implant (AADI) placed in eyes with refractory primary congenital glaucoma (PCG) versus aphakic glaucoma (APG). DESIGN Retrospective comparative interventional case series. METHODS Case files of consecutive eyes with PCG or APG that underwent AADI surgery between January 2013 and December 2016 and had a minimum 4 years follow-up were extracted from a computerised database. Failure was defined as intraocular pressure (IOP)>21 mm Hg or reduced<20% below baseline on two consecutive follow-up visits after 3 months, IOP≤5 mm Hg on two consecutive follow-up visits after 3 months, reoperation for glaucoma or a complication, or loss of light perception. RESULTS Eighty-nine eyes underwent AADI placement, including 42 eyes (47%) with PCG and 47 eyes (53%) with APG. Both groups were comparable at baseline. At 1 year, the APG group had lower mean IOP (13.6±8.1 mm Hg vs 17.6±7.5 mm Hg, p=0.02) with use of fewer IOP-lowering medications (0.8±1.0 vs 1.5±1.0, p=0.01) than the PCG group. The cumulative failure rate at 4 years was 57% (95% CI 43% to 72%) in PCG versus 40% (95% CI 28% to 56%) in the APG eyes (p=0.11). Eyes with PCG had greater tube-related complications (48% vs 38%, p=0.07) and number of reoperations (40% vs 32%, p=0.02) compared with eyes with APG. CONCLUSIONS Eyes with APG had relatively better outcomes after AADI placement compared with PCG during 4 years of follow-up. Reoperations accounted for more than 70% of the failures.

Ophthalmology 2023; 130:1162-1173. [PMID: 37454696 DOI: 10.1016/j.ophtha.2023.07.006] [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: 05/27/2023] [Revised: 06/27/2023] [Accepted: 07/10/2023] [Indexed: 07/18/2023] Open
Abstract
PURPOSE To estimate the long-term surgical and visual outcomes in patients with primary congenital glaucoma (PCG) who completed at least 20 years of follow-up. DESIGN Retrospective study. PARTICIPANTS Two hundred twenty eyes of 121 patients undergoing surgery for PCG between January 1991 and December 2000 and who returned for a follow-up visit from January 2021 through January 2022. METHODS Retrospective review of medical records of patients who underwent primary combined trabeculotomy-trabeculectomy (CTT) without mitomycin C as an initial procedure. Success was defined as complete when intraocular pressure (IOP) was ≥ 6 mmHg and ≤ 21 mmHg without glaucoma medication and as qualified when up to 2 glaucoma medications were required. Failure was defined as uncontrolled IOP with more than 2 glaucoma medications, need for a second IOP-lowering procedure, chronic hypotony (IOP < 6 mmHg on 2 consecutive visits), or any sight-threatening complication. A mixed-effects model using maximum likelihood estimation was used in estimation of eye-based variables and to make comparisons between different visits. Kaplan-Meier survival analysis was used to estimate the probabilities of surgical and functional successes. Cox proportional hazards regression using sandwich clustered estimation was used to evaluate risk factors for failure and poor visual outcome. MAIN OUTCOME MEASURES Primary outcome measure was the proportion of patients who demonstrated complete success over the 20-year follow-up. Secondary outcome measures included rate of surgical failure and need for reoperation for glaucoma, visual acuity, refractive errors, risk factors for poor outcome, and complications. RESULTS Kaplan-Meier survival analysis revealed 1-year, 10-year, and 20-year complete success rates of 90.7%, 78.9%, and 44.5%, respectively. In univariate analysis, surgical failure was higher among patients with any additional non-glaucoma intraocular surgery. None of the clinical parameters were associated significantly with failure in multivariable analysis. Overall, the proportion of eyes with good, fair, and poor visual outcomes was 33.2%, 16.4%, and 50.4%, respectively. Myopia was seen in 68.9% eyes. Twenty-eight eyes of those who underwent primary CTT (14.4%) required second surgery for IOP control. No significant intraoperative complications occurred. Six eyes required enucleation because of painful blind eye. CONCLUSIONS In this large cohort of patients with PCG, CTT is a useful procedure. It provides good IOP control and moderate visual recovery that remained over a 20-year follow-up after surgery.

Abstract
We performed a retrospective review of patients with refractory pediatric glaucoma who were started on netarsudil at the Wilmer Eye Institute. We found minimally sustained IOP lowering over a 6-month period in 29 eyes of 23 patients. Our results suggest that although netarsudil is an alternative medication in the management of pediatric glaucoma, its efficacy may be limited in refractory pediatric glaucoma patients. In addition, careful cornea examination is required to evaluate for signs of corneal decompensation, especially in patient with preexisting cornea disease.

Abstract
PRCIS Angle procedures are safe and relatively effective for neonatal onset PCG. Watchful delay in intervention to close to the second month of life is helpful in ensuring diagnosis and making surgery more successful and easier. PURPOSE The purpose of this study was to compare the surgical outcomes of visco-circumferential-suture-trabeculotomy (VCST) to rigid-probe double-entry viscotrabeculotomy (DEVT) and rigid-probe single-entry viscotrabeculotomy (SEVT) in infants with neonatal-onset primary congenital glaucoma (PCG). DESIGN This was a retrospective chart review. PATIENTS AND METHODS Retrospective chart review of 64 eyes of 64 infants with neonatal-onset PCG referred to Mansoura Ophthalmic Center in Mansoura, Egypt between February 2008 and November 2018. Study groups included VCST, DEVT, and SEVT, and follow-up covered 4 postoperative years. Complete (qualified) success was defined as intraocular pressure (IOP) ≤18 mm Hg and with 35% IOP reduction from baseline without (with) IOP-lowering medications or further surgical interventions, and without any sign of progression in corneal diameter, axial length, or optic disc cupping and without visual devastating complications. RESULTS The mean±SD age at presentation and at the surgery of the study children was 3.63±1.74 and 55.23±1.60 days, respectively. The mean±SD IOP and cup/disc ratio of all study eyes at presentation and at final follow-up were 34.91±0.82 mm Hg and 0.70±0.09 and 17.04±0.74 mm Hg and 0.63±0.08, respectively. Complete success was achieved in 54.5%, 43.5%, and 31.6% in the VCST, DEVT, and SEVT groups, respectively. A self-limited hyphema was the commonest complication in all groups. CONCLUSIONS Angle procedures are safe and marginally effective for the surgical treatment of neonatal-onset PCG, bringing IOP under control for at least 4 years of follow-up. Circumferential trabeculotomy as a first-line treatment has more favorable outcomes than rigid-probe SEVT. Rigid-probe viscotrabeculotomy offers an alternative to the noncompleted circumferential procedure.

Abstract
Glaucoma drainage devices (GDD) are increasingly utilized in the management of childhood glaucoma. This systematic review and meta-analysis assesses the efficacy of first-time Ahmed or Baerveldt implantation in children. PubMed, Embase, and Cochrane Library were searched for relevant English-language, peer-reviewed literature. Postoperative outcomes were pooled using random effects regression models with restricted maximum likelihood estimation. Thirty-two studies (1,221 eyes, 885 children) were included. Mean ± standard deviation preoperative IOP was 31.8 ± 3.4 mm Hg. Pooled mean IOP at 12 and 24 months postoperatively were 16.5 mm Hg (95% CI, 15.5-17.6) and 17.6 mm Hg (95% CI, 16.4-18.7), respectively. Pooled proportions of success were 0.87 (95% CI, 0.83-0.91) at 12 months, 0.77 (95% CI, 0.71-0.83) at 24 months, 0.54 (95% CI, 0.44-0.65) at 48 months, 0.60 (95% CI, 0.48-0.71) at 60 months, and 0.37 (95% CI, 0.32-0.42) at 120 months. There were no differences in proportion of success at 12 and 24 months among eyes that received Ahmed and Baerveldt tube shunts, nor between eyes with primary glaucoma, glaucoma following cataract surgery, or other secondary glaucoma. Our findings show that Ahmed and Baerveldt shunts substantially reduced IOP for at least 24 months in childhood glaucoma, with similar findings among device types and glaucoma etiologies.

Abstract
PRCIS Gonioscopy-assisted transluminal trabeculotomy (GATT) provided effective intraocular pressure (IOP) control in primary congenital glaucoma (PCG). Also, approximately two third of patients did not need antiglaucoma medication at an average follow-up of 1 year after surgery. PURPOSE The purpose of this study was to assess the safety and efficacy of GATT surgery in eyes with PCG. MATERIALS AND METHODS This study is a retrospective review of patients who underwent GATT surgery for PCG. Outcome measures were changes in IOP and number of medications at all time points (1, 3, 6, 9, 12, 18, 24, and 36 mo after surgery), and success rates. Success was defined as IOP<21 mm Hg with at least a 30% reduction from the baseline, complete if without medications, or qualified if with or without medications. Cumulative success probabilities were analyzed using the Kaplan-Meier survival analyses. RESULTS Twenty-two eyes of 14 patients diagnosed with PCG were enrolled in this study. The mean IOP reduction was 13.1 mm Hg (57.7%) with a mean decrease of 2 glaucoma medications at the final follow-up. All mean IOP readings during postoperative follow-up were significantly lower than baseline ( P <0.05 for all). Cumulative probability of qualified success was 95.5% and the cumulative probability of complete success was 66.7%. CONCLUSION GATT was safe and successfully lowered IOP in patients with PCG with the advantage of avoiding conjunctival and scleral incisions.

Abstract
Pediatric glaucoma is a constellation of challenging ophthalmic conditions that, left untreated, can result in irreversible vision loss. The mainstay of treatment for primary congenital glaucoma and select secondary glaucoma subtypes is angle surgery, either trabeculotomy or goniotomy. More recently, MIGS devices have been utilized to enhance the efficacy of these procedures. Despite the high success rates of these primary surgical options, refractory cases are challenging to manage. There is no consensus on the next step of treatment following primary angle surgery. Glaucoma drainage devices and trabeculectomies have been the traditional options, with laser treatment reserved for more severe cases. The benefits and disadvantages of each of these options are discussed.

Abstract
Pediatric glaucoma surgery is challenging due to its diverse and complex pathophysiology, altered anterior segment anatomy, greater potential for failure, and complications compared to adult patients. Moreover, numerous challenges are associated with long-term postoperative management. Thus, when dealing with childhood glaucoma, it is important to consider the potential complications in addition to the benefits of each intervention. The purpose of this article is to review recently published literature to shed light on the most recent surgical techniques for the safe and effective treatment of childhood glaucoma. Current literature shows that goniotomy and trabeculotomy are the first choices for the management of primary congenital glaucoma. Although older children with phakic eyes seem to benefit from trabeculectomy with adjunctive mitomycin C, it carries a long-term risk of bleb-related endophthalmitis. Glaucoma drainage devices may be preferred for patients with secondary or refractory glaucoma. However, hypotony or tube-related complications are common and encountered more often in children than in adults. Cyclodestructive procedures are also an option for cases in which filtering surgery has failed, but they can also be used as a temporizing measure to reduce the rate of complications in high-risk patients. However, their outcomes can be unpredictable, in terms of efficiency and complications. Finally, minimally invasive glaucoma surgery (MIGS) as the sole alternative treatment or as an adjunctive surgical procedure is a relatively new path for pediatric patients.

Abstract
Secondary glaucoma is still a blinding complication in childhood uveitis, for which most commonly used surgical interventions (trabeculectomy or glaucoma drainage implant) involve multiple re-interventions and/or complications postoperatively. The goniotomy procedure has never been investigated in the current era, in which patients with pediatric uveitis receive biologics as immunosuppressive therapy for a prolonged period, with potential implications for the outcome. The purpose of the study is to evaluate the efficacy and safety of a goniotomy procedure in pediatric non-infectious uveitis in a retrospective, multicenter case series. The primary outcomes were the postoperative intraocular pressure (IOP), number of IOP-lowering medications, and success rate. Postoperative success was defined as 6 ≤ IOP ≤ 21 mmHg, without major complications or re-interventions. Fifteen eyes of ten children were included. Median age of the included patients at goniotomy was 7 years; median follow-up was 59 months. Median (interquartile range) IOP before surgery was 30 (26–34) mmHg with 4 (3–4) IOP-lowering medications. At 1, 2, and 5 years after goniotomy, median IOP was 15, 14, and 15 mmHg with 2 (0–2), 1 (0–2), and 0 (0–2) medications, respectively (p < 0.001 postoperatively versus preoperatively for all timepoints). Success rate was 100%, 93%, and 80% after 1, 2, and 5 years, respectively. There were no significant changes in visual acuity and uveitis activity or its treatment, and there were no major complications. Our results show that the goniotomy is an effective and safe surgery for children with uveitic glaucoma.

Abstract
We are pleased to bring you the 5th edition of the Glaucoma Clinical Practice Guidelines. Clinical practice guidelines are based on evidence (scientific grounds). It is a document that presents the treatment that is the most appropriate for the patient. "Glaucoma Clinical Guidelines" was first published in 2003. This was the first guideline for glaucoma treatment in Japan. The principle of glaucoma treatment is to lower intraocular pressure. Means for lowering intraocular pressure includes drugs, lasers, and surgery; Glaucoma is a disease that should be considered as a complex syndrome rather than a single condition. Therefore, the actual medical treatment is not as simple as one word. This time we set the Clinical Questionnaire with a focus on glaucoma treatment. We hope that you will take advantage of the 5th edition.

Efficacy and safety of the PreserFlo implant with mitomycin C in childhood glaucoma after previous failed glaucoma surgeries. Graefes Arch Clin Exp Ophthalmol 2022; 261:1349-1357. [PMID: 36536223 DOI: 10.1007/s00417-022-05939-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 12/07/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022] Open
Abstract
PURPOSE This study aims to evaluate the efficacy and safety of the PreserFlo MicroShunt (Santen, Osaka, Japan) in lowering intraocular pressure (IOP) in childhood glaucoma patients with previous failed glaucoma surgeries. METHODS This is a prospective case review of consecutive PreserFlo procedures performed in childhood glaucoma patients after failed surgeries. Age, sex, diagnosis, and previous glaucoma surgeries, as well as visual acuity, IOP, and treatment in the preoperative visit and all follow-up visits were collected. Outcome measures included IOP reduction from baseline, mean IOP change from baseline at month 6, medication use at 6 months, complications, adverse events, and need for further procedures. RESULTS Fourteen patients were included, 8 (57%) males and 6 (43%) females; the mean age was 27.5 ± 13.5 years. Nine patients (64%) had at least two trabeculectomies, and 6 patients (43%) had at least one trabeculectomy and a glaucoma drainage implant. The mean IOP change from baseline was 11.3 ± 4.9 mmHg at 12 months. At 12 months, 12 patients (86%) presented ≥ 20% IOP lowering from baseline, and 11 patients (79%) presented ≥ 30%. The mean medication count decreased from 3.9 ± 0.7 (baseline) to 0.7 ± 1.3 (12 months). No intraoperative complications were reported. No adverse events were noted. No secondary filtration surgery was required, although bleb needling was required in one case, 1 month after the surgery. CONCLUSIONS PreserFlo with MMC can be used successfully to treat uncontrolled IOP in childhood glaucoma cases with previous failed surgeries. Larger studies with longer follow-up are needed to further explore the role of the device in resistant childhood glaucoma cases.

Abstract
Purpose This study aimed to develop a fully automated deep learning ciliary body segmentation and assessment approach in three-dimensional ultrasound biomicroscopy (3D-UBM) images. Methods Each 3D-UBM eye volume was aligned to the optic axis via multiplanar reformatting. Ciliary muscle and processes were manually annotated, and Deeplab-v3+ models with different loss functions were trained to segment the ciliary body (ciliary muscle and processes) in both en face and radial images. Results We trained and tested the models on 4320 radial and 3864 en face images from 12 cadaver eye volumes. Deep learning models trained on radial images with Dice loss achieved the highest mean F1-score (0.89) for ciliary body segmentation. For three-class segmentation (ciliary muscle, processes, and background), radial images with Dice loss achieved the highest mean F1-score (0.75 for the ciliary process and 0.82 for the ciliary muscle). Part of the ciliary muscle (10.9%) was misclassified as the ciliary process and vice versa, which occurred owing to the difficulty in differentiating the ciliary muscle–processes border, even by experts. Deep learning segmentation made further editing by experts at least seven times faster than a fully manual approach. In eight cadaver eyes, the average ciliary muscle, process, and body volumes were 56 ± 9, 43 ± 13, and 99 ± 18 mm3, respectively. The average surface area of the ciliary muscle, process, and body were 346 ± 45, 363 ± 83, and 709 ± 80 mm2, respectively. We performed transscleral cyclophotocoagulation in cadaver eyes to shrink the ciliary processes. Both manual and automated measurements from deep learning segmentation show a decrease in volume, surface area, and 360° cross-sectional area measurements. Conclusions The proposed deep learning segmentation of the ciliary body and 3D measurements showed transscleral cyclophotocoagulation-related changes in the ciliary body. Translational Relevance Automated ciliary body assessment using 3D-UBM has the translational potential for ophthalmic treatment planning and monitoring.

Outcomes of inferonasal glaucoma drainage device surgery in the management of childhood glaucoma. J AAPOS 2022; 26:232.e1-232.e7. [PMID: 36122872 DOI: 10.1016/j.jaapos.2022.06.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 06/19/2022] [Accepted: 06/24/2022] [Indexed: 11/21/2022]
Abstract
PURPOSE To evaluate indications and postoperative outcomes of inferonasal Ahmed and Baerveldt glaucoma drainage devices (GDDs) in pediatric glaucoma. METHODS This retrospective study included patients ≤18 years of age at inferonasal GDD placement, from June 2013 to September 2021. Demographic information, indications, and outcomes were recorded. Successful eyes had intraocular pressure (IOP) ≥5 and ≤21 mm Hg or (in severe cases, where entry IOP was ≤21 mm Hg) 20% below preoperative values without additional IOP-lowering surgery or vision-threatening complications. RESULTS A total of 68 eyes of 52 patients were included. Mean age was 9.8 ± 5.8 years. Most common diagnoses included primary congenital glaucoma (n = 28 eyes [41%]) and glaucoma following cataract surgery (n = 12 eyes [18%]). Success rates by Kaplan-Meier survival analysis (95% CI) at 1, 2, 3, and 5 years were 62.2% (49.4-72.7), 49.0% (36.3-60.6), 36.8% (24.0-49.8), and 31.9% (18.5-44.5), respectively. Surgical failure was associated with Ahmed (vs Baerveldt) GDD (HR = 3.2; P = 0.002) and inferonasal site as initial (vs subsequent) GDD received (HR = 2.2; P = 0.048). Twenty-five eyes (36.7%) had at least one complication. Although vision-threatening complications were uncommon (n = 2 eyes [3%]), less severe complications were relatively common and included new/worsened strabismus (n = 9 patients [17%]), corneal edema (n = 6 eyes [9%]), lens opacities (n = 4 [6%]), tube or patch graft exposure (n = 3 [4%]), tube blockage (n = 2 eyes [3%]), and other (n = 8 eyes [12%]). CONCLUSIONS In this study cohort, inferonasal GDDs for childhood glaucoma had modest success, with frequent though rarely vision-threatening complications.

Abstract
INTRODUCTION Primary congenital glaucoma (PCG), a type of childhood glaucoma, is primarily treated surgically to lower intraocular pressure (IOP). Failure to intervene could result in partial, or even total, blindness. Various surgical intervention types have been proposed for PCG, though the evidence on comparative effectiveness remains limited. The current protocol is an ongoing network meta-analysis enabling comparative investigation of surgical interventions for which randomised controlled trials (RCTs) are available. Our aim is to systematically compare the efficacy of various types of surgical intervention for patients with PCG. METHODS AND ANALYSIS Studies of interest will assess the effects of those surgical interventions on surgery-naïve children (age <18 years) suffering PCG. RCTs regardless of language or publication date will be searched from three electronic databases (Cochrane Central Register of Controlled Trials, Embase and MEDLINE) from 4 April 2022. Two reviewers will screen, first, titles and abstracts, followed by full-text papers, for useful data that they will extract. The primary outcome measure will be the IOP-lowering effect of a given surgical intervention. The two reviewers also will assess the internal validity of studies using the relevant and domain-based risk-of-bias assessment tool. Overall evidence quality will be assessed according to the Confidence in Network Meta-Analysis approach and will be presented in summarised form with network diagrams. For enhanced visualisation of the included interventions' effects, forest plots will be constructed. Pairwise effect sizes also will be calculated based on the evidence that is available in the network. ETHICS AND DISSEMINATION This work will synthesise evidence obtained from published studies, and as such, no ethics review or approval will be required. A paper presenting the findings will be submitted to a peer-reviewed scientific journal for publication. PROSPERO REGISTRATION NUMBER CRD42022313954.

Abstract
PURPOSE Development and validation of a decision tree model (DTM) for prediction of mental health status in Korean caregivers of children with glaucoma. DESIGN Cross-sectional study. METHODS Caregivers of children younger than 18 years with diagnosed primary childhood glaucoma (n = 42), secondary childhood glaucoma (n = 51), and glaucoma suspect (GS; n = 36) were prospectively enrolled at Seoul National University Children's Hospital, Seoul, Korea. The participants completed 2 questionnaires, the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder (GAD-7) Assessment. A DTM analysis for discrimination of those with moderate-to-severe depressive (PHQ-9 score ≥10) and anxiety (GAD-7 score ≥11) symptoms was performed with recursive partitioning algorithms based on the obtained clinical, demographic, and socioeconomic data. RESULTS The mean PHQ-9 and GAD-7 scores did not significantly differ among the 3 groups (P = .823 for PHQ-9 score; P = .730 for GAD-7 score). The DTM's balanced accuracies were 0.875 (95% CI = 0.778-0.972) for the PHQ-9 score and 0.880 (95% CI = 0.800-0.960) for theGAD-7 score. The DTM of the PHQ-9 revealed that in caregivers of children with glaucoma, depressive symptoms should be strongly suspected when (1) the child has undergone more than 2 glaucoma surgeries; or (2) the visual acuity (VA, converted to logarithm of minimum angle of resolution [logMAR]) in the better eye is worse than 0.4 if the child has had only 1 or no surgery. CONCLUSIONS Evaluation of the number of glaucoma surgeries and VA in the better eye can be a useful decision support tool in predicting mental illness in caregivers of children with glaucoma.

Abstract
In recent years, glaucoma tube surgery has been recommended for refractory cases that have failed to respond to angle surgery. In this study, we described the case of the fibrous proliferative membrane caused in the anterior chamber after Ahmed glaucoma valve implantation in a pediatric glaucoma patient. He was born full term, weighing 3228 g. Corneal opacity in both eyes was seen at birth and he was referred to the Department of Ophthalmology, Hiroshima University Hospital on the 13th day of his life. At the initial examination, the intraocular pressure was 37mmHg right 25mmHg left. Corneal diameter expansion and diffuse corneal opacity were seen in both eyes. Nine days after the initial examination, trabeculotomy was performed in both eyes but they were ineffective, and Ahmed glaucoma tubes were inserted in both eyes two months later. Four months later the intraocular pressure remained 30mmHg range in both eyes and micropulse cyclophotocoagulation was performed. One year after the Ahmed glaucoma valve implantation, the tube of right eye was exposed, and we planned to perform a repair procedure. At this time, ultrasound biomicroscopy (UBM) showed proliferative tissue around both tubes. They were removed next month. Although silicone is a highly biocompatible material, it can cause foreign body reactions such as encapsulation around the silicone plate and proliferative membranes around silicone oil. We speculated that a similar reaction occurred to the silicone tube in this case. We reported a case of fibrous proliferative membrane in the anterior chamber. This might be caused by the silicon tube of the Ahmed glaucoma valve.

Abstract
Primary congenital glaucoma (PCG) is an ocular disease characterized by congenital anterior segmental maldevelopment with progressive optic nerve degeneration. Certain genes, such as cytochrome P450 family 1 subfamily B member 1 and latent TGF-β-binding protein 2, are involved in the pathogenesis of PCG, but the exact pathogenic mechanism has not yet been fully elucidated. There is an urgent need to determine the etiology and pathophysiology of PCG and develop new therapeutic methods to stop disease progression. Animal models can simulate PCG and are essential to study the pathogenesis and treatment of PCG. Various animal species have been used in the study of PCG, including rabbits, rats, mice, cats, zebrafish, and quails. These models are formed spontaneously or by combining with genetic engineering technology. The focus of the present study is to review the characteristics and potential applications of animal models in PCG and provide new approaches to understand the mechanism and develop new treatment strategies for patients with PCG.

Am J Ophthalmol 2022; 236:79-88. [PMID: 34695398 DOI: 10.1016/j.ajo.2021.10.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 09/30/2021] [Accepted: 10/09/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE To identify risk factors for surgical failure after gonioscopy-assisted transluminal trabeculotomy (GATT) in juvenile open-angle glaucoma (JOAG). DESIGN Prospective, interventional case series. METHODS GATT was the initial surgery in 70 eyes of 70 patients with JOAG. Surgical success was defined as a postoperative intraocular pressure (IOP) of ≤21 mm Hg with at least a 20% reduction from preoperative IOP, with or without the use of antiglaucoma medication (qualified and complete success, respectively) at each postoperative visit. IOP spike was defined as IOP >30 mm Hg and an increase of at least 10 mm Hg from IOP before the spike, and then reduced to ≤21 mm Hg. RESULTS The median age at the time of surgery was 19.3 years (range, 4.9-37.5 years) with a visual field mean deviation of -17.4 ± 10.6 dB. Mean IOP decreased from 31.3 ± 9.5 mm Hg preoperatively to 15.8 ± 2.7 at 12 months postoperatively. The complete and qualified success rates were 74.3% and 91.4%, respectively. An IOP spike occurred in 52 eyes (74%), with a median spike duration of 3.5 days (range, 1-21 days). Longer duration of IOP spike (P = .009) and older age at the time of surgery (P = .025) were both associated with worse surgical outcomes. Advanced disease was associated with prolonged IOP spike (P = .007). CONCLUSIONS GATT provided excellent outcomes in patients with severe JOAG. Older age and longer duration of postoperative IOP spike are risk factors for failure. Severe cases are more likely to have longer durations of IOP spike. Frequent IOP monitoring during the early postoperative period is needed to detect IOP spikes in these patients.

Abstract
PURPOSE To present the outcomes and factors affecting the success of trabeculectomy performed as the first surgery in primary pediatric glaucoma. METHODS Pediatric patients with primary glaucoma who underwent trabeculectomy as the first surgery were retrospectively reviewed. Age, gender, preoperative intraocular pressure (IOP), operation age, axial length, corneal diameter, anterior segment findings, antimetabolite used, complications, and 1-month, 3-months, 1-year, and most recent postoperative findings were recorded. Postoperative IOP with/without medication of 18 mmHg or less was considered successful. Factors that may have affected surgical success were also evaluated using multivariate analysis. RESULTS Included in the study were 48 patients, of whom 30 had primary congenital glaucoma and 18 had juvenile glaucoma. The mean preoperative IOP was 36.84 ± 6.30 mmHg, and the mean follow-up time was 7.95 ± 6.93 years. The median operation age value was 100.00 ± 100.83 (median: 60; IQR: 153) months. The postoperative IOP at the 1-month, 3-months, 1-year, and most recent follow-ups were 15.39 ± 6.88, 15.70 ± 7.36, 16.28 ± 7.86, and 17.48 ± 8.44 mmHg, respectively (p = 0.565). While there were no postoperative complications in 24 of the patients (50.0%), the most common complications were choroidal detachment and hypotony. Postoperative complication development was found to be significant as a factor affecting surgical success in the multivariate logistic regression analysis. Surgical success rates for all of the patients were 71.7%, 65.9%, 65.0%, and 61.4% at the 1-month, 3-months, 1-year, and most recent follow-ups, respectively. A significant difference was found between the congenital and juvenile groups in terms of surgical success only at 3 months (p = 0.953, p = 0.042, p = 0.191, p = 0.218; respectively). DISCUSSION/CONCLUSION The fact that surgical success was partially higher in the juvenile group confirmed the idea that the results of trabeculectomy will be more favorable in patients of older age and without anterior segment anomalies.

Abstract
PURPOSE OF REVIEW Minimally invasive glaucoma surgery (MIGS) has been shown to be safe and effective in treatment of mild to moderate glaucoma in adults, but reports in childhood glaucoma are limited. We review the available data concerning MIGS and discuss its potential role in childhood glaucoma management. RECENT FINDINGS Ab interno counterparts to circumferential ab externo trabeculotomy such as gonioscopy-assisted transluminal trabeculotomy (GATT) and Trab360 show promise in treatment of primary glaucomas as reported in a few retrospective case series. Kahook Dual Blade (KDB) and Trabectome have demonstrated mixed results in few published case reports in children. Small case series and reports suggest that the Xen gel stent can be a safer alternative to traditional filtration surgery, though data on long-term implant and bleb stability are unavailable. Newer devices are being investigated and early results are encouraging. SUMMARY GATT and Trab360 seem to be safe, effective methods of achieving circumferential trabeculotomy in childhood glaucoma. KDB, Trabectome, and Xen gel stent have shown some success in selected cases with short-term follow-up. Surgeons must determine the risks and benefits of MIGS over more established methods of intraocular pressure reduction for each individual child. Further research is needed to validate initial findings regarding MIGS in childhood glaucoma.

Abstract
Glaucoma remains a frequent serious complication following cataract surgery in children. The optimal approach to management for 'glaucoma following cataract surgery' (GFCS), one of the paediatric glaucoma subtypes, is an ongoing debate. This review evaluates the various management options available and aims to propose a clinical management strategy for GFCS cases. A literature search was conducted in four large databases (Cochrane, PubMed, Embase, and Web of Science), from 1995 up to December 2021. Thirty-nine studies-presenting (1) eyes with GFCS; a disease entity as defined by the Childhood Glaucoma Research Network Classification, (2) data on treatment outcomes, and (3) follow-up data of at least 6 months-were included. Included papers report on GFCS treated with angle surgery, trabeculectomy, glaucoma drainage device implantation (GDD), and cyclodestructive procedures. Medical therapy is the first-line treatment in GFCS, possibly to bridge time to surgery. Multiple surgical procedures are often required to adequately control GFCS. Angle surgery (360 degree) may be considered before proceeding to GDD implantation, since this technique offers good results and is less invasive. Literature suggests that GDD implantation gives the best chance for long-term IOP control in childhood GFCS and some studies put this technique forward as a good choice for primary surgery. Cyclodestruction seems to be effective in some cases with uncontrolled IOP. Trabeculectomy should be avoided, especially in children under the age of one year and children that are left aphakic. The authors provide a flowchart to guide the management of individual GFCS cases.

Abstract
Although trabeculotomy and goniotomy are currently the mainstay of surgical management for congenital glaucoma, XEN Gel Stent (Allergan) implantation and other microinvasive glaucoma surgery technologies may offer the advantage of having a lower risk of postoperative complications than conventional techniques. A 10-year-old boy presented with aphakic glaucoma in his left eye secondary to previous cataract surgery. Intraocular pressure (IOP) in the left eye at initial presentation was 31 mm Hg with maximal tolerated medical therapy. Surgical history included tube shunt, shunt revision, and subsequent shunt removal. Shunt surgery and revision had been unsuccessful at achieving target IOP. The patient underwent two treatments of micro-pulse transscleral laser therapy that failed to achieve target IOP. At this time, an open conjunctiva ab externo superior XEN Gel Stent (Allergan) was implanted. Within 1 month of surgery, conjunctival dehiscence and contraction occurred. Following this, ab interno inferonasal air-ophthalmic viscosurgical device XEN Gel Stent implantation was performed. In the 6 months following the second XEN Gel Stent, IOP in the left eye was stable at 6 to 8 mm Hg. This report describes the effective use of a XEN Gel Stent implant in the management of congenital glaucoma, while also highlighting a complication. Further studies are required to determine the comparative outcomes of this technique with conventional surgical management. [J Pediatr Ophthalmol Strabismus. 2022;59(1):e11-e14.].

Abstract
To quantify the results of childhood glaucoma treatment over time in a cohort of children with different types of childhood glaucoma. A retrospective cohort study of consecutive cases involving children with primary congenital glaucoma, primary juvenile, and secondary juvenile glaucoma at the Childhood Glaucoma Center, University Medical Center Mainz, Germany from 1995 to 2015 was conducted. The main outcome measure was the long-term development of intraocular pressure. Further parameters such as surgical success, refraction, corneal diameter, axial length, and surgical procedure in children with different types of childhood glaucoma were evaluated. Surgical success was defined as IOP < 21 mmHg in eyes without a need for further intervention for pressure reduction. A total of 93 glaucomatous eyes of 61 childhood glaucoma patients with a mean age of 3.7 ± 5.1 years were included. The overall mean intraocular pressure at first visit was 32.8 ± 10.2 mmHg and decreased to 15.5 ± 7.3 mmHg at the last visit. In the median follow-up time of 78.2 months, 271 surgical interventions were performed (130 of these were cyclophotocoagulations). Many (61.9%) of the eyes that underwent surgery achieved complete surgical success without additional medication. Qualified surgical success (with or without additional medication) was reached by 84.5% of the eyes.

Abstract
PURPOSE To evaluate the long-term efficacy and safety of circumferential trabeculotomy (CT) in the treatment of primary congenital glaucoma (PCG). METHODS Retrospective, single-institutional case series of CT performed for PCG in years 1997-2016. The surgery could be completed in 42 out of 65 eyes (65%) intended for CT, and 39 of them were included in the study. A follow-up examination was performed in 2017. Success was defined as intraocular pressure ≤ 16 mmHg without (complete) or with (qualified) glaucoma medication. RESULTS Complete success was obtained in 33/39 eyes (85%), qualified success in 34/39 eyes (87%). Of the 39 eyes with CT, 4 eyes (10%) needed additional surgery. Median follow-up time was 120 months (range, 19-245 months). Median pre- and postoperative IOP were 26.0 mmHg (range, 10-41 mmHg) and 11.0 mmHg (range, 8-19 mmHg), respectively (p < 0.001). Cup-disc ratio was ≥0.5 in 82% at baseline, at follow-up in 9%. The median distance corrected visual acuity at follow-up was logMAR 0.06 (range, -0.2 to 1.1). Median number of glaucoma medication at follow-up was 0 (range, 0-2), at baseline 1.0 (range, 0-2). No serious complications were noted. CONCLUSION Circumferential trabeculotomy is an efficacious, safe and medication saving surgical treatment for PCG in the long term. After a median follow-up of 10 years (120 months), the morphological status of the optic nerve was either normalized or stabilized, and the visual acuity overall well preserved.

Abstract
PURPOSE The aim was to evaluate the short-term outcomes of Ahmed clear path (ACP) valveless glaucoma drainage device in childhood glaucoma. METHODS Retrospective chart review of all patients 16 years or below with childhood glaucoma who had ACP implantation at Boston Children's Hospital from December 2019 to June 2020 with at least 6 months follow-up period. RESULTS The study included 7 eyes of 5 patients implanted by a single surgeon. The median follow-up was 12 months. The mean intraocular pressure (IOP) was reduced from 36±3.5 mm Hg on a mean of 2.7±0.6 glaucoma medications preoperatively to a mean IOP of 12.4±2.8 mm Hg (P<0.001) on a mean of 0.7±0.8 medications postoperatively at final follow-up (P=0.0009). Complete success was achieved in 4 eyes while qualified success was achieved in 3 eyes. CONCLUSION The ACP glaucoma drainage device provided good short-term IOP control and technical advantages for implantation for pediatric eyes were observed.

Abstract
PURPOSE To report the clinical outcomes of glaucoma management in patients with phacomatosis pigmentovascularis (PPV) treated over a period of 3 decades. DESIGN Retrospective cohort study. PARTICIPANTS Fifty-five eyes of 38 patients (21 unilateral and 17 bilateral) with glaucoma in PPV managed at one institution between January 1990 and December 2019 with a minimum follow-up of 1 year. METHODS Medical records of children with glaucoma in PPV were reviewed, and demographic and clinical data were collected. Surgical interventions included primary combined trabeculotomy-trabeculectomy (CTT), trabeculectomy with mitomycin C (MMC), and transscleral cyclophotocoagulation (TSCPC). Complete success was defined as intraocular pressure (IOP) ≥ 6 and ≤ 16 mmHg without medications and qualified success as IOP ≤ 16 mmHg with the use of up to 2 medications. MAIN OUTCOME MEASURES Intraocular pressure, best-corrected visual acuity (BCVA), corneal clarity, antiglaucoma medications at preoperative and postoperative visits (last visit), and complications. RESULTS Median age was 4 months (range, 0.2-252 months) at the time of glaucoma surgery. Thirty-nine eyes (74%) had primary CTT, 10 eyes (19%) had trabeculectomy with MMC, and 4 eyes (7%) with advanced glaucoma had TSCPC. Two eyes (3.6%) received medical treatment. Preoperative IOP reduced from a mean of 25.7 ± 8.4 mmHg on 0.8 ± 0.6 medications to 14.6 ± 5.2 mmHg on 0.4 ± 0.5 medications (P < 0.0001) at last follow-up after surgery (77.7 ± 56.5 months). Thirty-seven eyes (67.3%) required medications preoperatively, and 22 eyes (40%) required medications at the last follow-up. Of 25 patients with available BCVA at last follow-up, 9 (36%) had ≥ 20/60; of these, 6 had > 20/40. Four of 10 eyes that underwent trabeculectomy with MMC developed retinal detachment and were managed surgically; however, all of these eyes had poor visual outcomes. There was no incidence of bleb leakage, bleb-related infection, or endophthalmitis. CONCLUSIONS Combined trabeculotomy-trabeculectomy is safe and effective as a primary procedure for management of glaucoma in PPV. Trabeculectomy augmented with MMC as a second procedure was associated with a higher rate of complications.

Abstract
Megalocornea and anterior megalophthalmos (megalocornea spectrum) disorders are typically defined by corneal diameter > 12.5 mm in the absence of elevated intraocular pressure. Clinical features overlap with keratoglobus but are distinct from buphthalmos and severe (globus) keratoconus. Megalocornea spectrum disorders and keratoglobus are primarily congenital disorders, often with syndromic associations; both can present with large and thin corneas, creating difficulty in diagnosis, however, only keratoglobus is typically progressive. Molecular genetics provide significant insight into underlying aetiologies. Nonetheless, careful clinical assessment remains intrinsic to diagnosis. Surgical management can be challenging due to the enlarged ciliary ring and weakened zonules in megalocornea spectrum disorders and the extreme corneal thinning of keratoglobus. In this review, the established literature on measurement of corneal diameter, diagnosis of megalocornea, anterior megalophthalmos and keratoglobus, differentiation from severe keratoconus, recent molecular genetics research and key surgical modalities in the management of these rare disorders are outlined and discussed.

Abstract
PURPOSE To evaluate the surgical success after trabeculotomy for primary congenital glaucoma (PCG) in Denmark in the last 40 years. METHODS Retrospective review of medical files on children who all underwent trabeculotomy as the first surgical intervention between January 1rst, 1977 and December 31, 2016. Information on diagnosis and surgical procedures were extracted. Primary outcome was surgical success was defined as intraocular pressure (IOP) < 21 mmHg without medications one year after surgery. Secondary outcome was the number of reoperations needed. RESULTS Out of 118 children with PCG, 96 children (144 eyes) had an ab externo trabeculotomy as primary IOP lowering procedure opening Schlemm's channel 4 clock hours into the anterior chamber. Complete surgical success at one year was achieved in 73% (106 of 144 eyes). On the long term, IOP could be controlled by one surgical procedure in 2/3 of children, eight eyes required >5 surgical procedures to control IOP. In 12.1% of children the second glaucoma procedure was performed >5 years after the initial trabeculotomy. There was a tendency towards greater risk of needing a second procedure in patients < 3 months of age at primary trabeculotomy (hazard ratio, HR, 2.01, 95% CI 0.96-4.22) and in boys (HR 2.02, 95% CI 0.97-4.18) and a lower risk of requiring a third surgery if the second surgery was trabeculectomy with MMC. CONCLUSION Dedicated follow-up of patients with PCG is essential as the disease may continue to progress even after years of quiescence and some children need multiple surgeries to control IOP. Additional glaucoma procedures are required in 1/3 of children and boys and younger patients seem to be at greater risk.

Abstract
PRECIS This paper reports a retrospective consecutive case series investigating the efficacy of Mitomycin C-augmented trabeculectomy in the treatment of primary and secondary pediatric glaucoma in a mixed etiology, multiethnic cohort of patients. PURPOSE To evaluate the long-term efficacy and safety of Mitomycin C-augmented trabeculectomy in a mixed, tertiary-referral, pediatric glaucoma cohort. METHODS Retrospective consecutive review of all children (37 eyes) undergoing Mitomycin C-augmented trabeculectomy by a single surgeon between 2008 and 2016. Seventeen eyes (45.9%) had primary congenital glaucoma, and 20 eyes (54.1%) had secondary glaucoma. The median age at surgery was 11 months (range, 2 to 146). The mean follow-up was 69.2±4.7 months (range, 3.5 to 107.9). RESULTS Overall, trabeculectomy was successful in 80.6% of eyes at 12 months, 60.5% at 3 years, and 57.5% at 5 years. 45.9% cases (17 eyes) required further laser or surgery for uncontrolled intraocular pressure (IOP) and were therefore deemed as failures. The time to failure ranged from 0.4 to 65.1 months (mean, 22.2±5.1 mo). The proportion of children achieving visual acuity of 1.0 LogMAR equivalent or better increased from 43.2% preoperatively to 63.6% at 1 year and 68% at 5 years. The mean IOP reduced from 24.85±0.88 mm Hg preoperatively to 15.14±0.94 mm Hg at 3 months (39% reduction) and 17.42±1.08 mm Hg at 5 years (30% reduction). IOP-lowering medication requirement reduced from 4.14±0.20 agents preoperatively to 0.84±0.22 at 3 months (80% reduction) and 1.78±0.36 at 5 years (57% reduction). There were no sight-threatening complications such as hyphaema, bleb leak, chronic hypotony, endophthalmitis, retinal detachment, or loss of light perception. CONCLUSIONS This study provides valuable evidence that Mitomycin C-augmented trabeculectomy is safe and effective as a treatment of primary or secondary pediatric glaucoma, with particularly encouraging results in cases of secondary glaucoma. Trabeculectomy offers the potential for delaying or avoiding glaucoma drainage device surgery in a significant proportion of children.

Abstract
PURPOSE We sought to describe the outcomes of the Aurolab aqueous drainage implant (AADI) placed in the superotemporal (ST) versus the inferonasal (IN) quadrant in pediatric eyes with refractory glaucoma. DESIGN Retrospective comparative interventional case series. METHODS This was a retrospective study of patients ≤18 years of age who underwent AADI implantation and completed a minimum of 2-year follow-up. The choice of the quadrant depended upon the amount of scarring and conjunctival mobility. Cumulative success at 2 years was defined as intraocular pressure (IOP) ≤21 mm Hg or reduced by ≥20% below baseline on 2 consecutive follow-up visits after 3 months, IOP ≤5 mm Hg on 2 consecutive follow-up visits after 3 months, reoperation for glaucoma or a complication, or loss of light perception vision. RESULTS A total of 144 patients (144 eyes) underwent AADI placement, including 48 eyes (33%) in the IN and 96 eyes (67%) in the ST quadrants. The IOP was significantly higher in the IN group (17.5 ± 7.4 mm Hg vs 13.7 ± 6.2 mm Hg, P = .005) with a greater number of medications (1.5 ± 1.0 vs 0.8 ± 0.9, P = .001) after 2 years of follow-up. Cumulative success rates at 2 years were 50.7% (95% confidence interval 35.4%-63.9%) in the IN group and 65.6% (95% confidence interval 56.5%-75.7%) in the ST group (P = .15). Complications occurred more frequently in the IN group, with significantly more tube exposure (12% vs 0%, P = .05). CONCLUSIONS Placement of the AADI in the ST quadrant has better IOP-related outcomes and is a safer surgical option in pediatric eyes compared with the IN quadrant. It may be prudent to avoid AADI in the IN quadrant in children unless the ST location is not a viable option.

Abstract
PURPOSE To determine the incidence and risk factors for glaucoma after pediatric cataract surgery with intraocular lens (IOL) implantation. DESIGN Retrospective, consecutive case series. METHODS In this single-center study, we reviewed 136 children (199 eyes) who underwent pediatric cataract surgery before 1 year of age with a minimum of 1 year of follow-up. The intervention used was pediatric cataract surgery with IOL implantation, and the primary outcome measure was the presence or absence of secondary glaucoma. RESULTS The mean age at surgery was 148 ± 93 days (range 30-359 days) with a mean follow-up of 6.3 ± 3.6 years (range 1.1-12.8 years). Glaucoma developed in 31 eyes (16%) with 5- and 10-year incidence rates of 12% and 28%, respectively. The incidence of glaucoma seemed to be bimodal, with a first peak occurring after a mean delay of 2.5 months (range 1.6-4.1 months) and a second peak occurring after a mean delay of 5.7 years (range 2.6-11.7 years). Younger age at surgery, shorter axial length, longer follow-up, use of trypan blue, reintervention, and bilateral surgery were associatied with a higher incidence of glaucoma. Multivariate analysis including the aforementioned variables indentified longer follow-up (odds ratio [OR] = 1.3 [95% confidence interval {CI} 1.1-1.6], P = .001), reintervention (OR = 4.1 [95% CI 1.2-13.4], P = 0.02), and the use of trypan blue (OR = 4.1 [95% CI 1.3-13.1], P = .02) as predictors for the development of glaucoma. CONCLUSION Glaucoma is a common complication after pediatric cataract surgery. It seemed to have a bimodal incidence. Risk factors for glaucoma development were reintervention, the use of trypan blue, and a long follow-up.

Abstract
PURPOSE To determine the incidence of postoperative complications following combined trabeculotomy trabeculectomy with mitomycin C (CTTM) for congenital glaucoma (CG), in addition to documentation of some unusual complications and possible ways to manage these complications safely with minimal morbidity. METHODS A retrospective observational study was performed on 190 eyes with CG had a CTTM procedure.Included eyes were operated upon between February 2015 and February 2020 in Sohag University Hospitals. Medical records were reviewed and postoperative complications were reported. Incidence of postoperative complications and their management were the main outcome measures. RESULTS Early complications developed the form of shallow anterior chamber (AC) (16.3%), hyphema (10.5%), serous choroidal detachment (2%), hemorrhagic choroidal detachment (2%). Unusual and rare complications occurred in the form of iatrogenic Cushing syndrome, unilateral toxic keratopathy developed, vitreous hemorrhage (VH), intercalary staphyloma and decompression retinopathyLate complications included: high postoperative intraocular pressure (IOP) (16.5%), thin cystic blebs (13.1%), hypotony disc edema (2%), cataract (3.2%), one eye developed blebitis and one eye developed endophthalmitis. CONCLUSION Surgical management of CG is full of complications in early and late postoperative periods such as shallow AC, hyphema and thin cystic blebs. Some unusual and rare complications developed such as iatrogenic Cushing syndrome, unilateral toxic keratopathy, vitreous hemorrhage, intercalary staphyloma and decompression retinopathy. If identified early; all these complications could be managed properly leading to a successful and favorable outcome.

Abstract
PURPOSE Report factors associated with failure and complication in a cohort of children who have undergone glaucoma drainage device (GDD) implantation. DESIGN Retrospective case series. PARTICIPANTS Consecutive pediatric GDD eyes that met criteria between May 1997 and July 2019. METHODS Entries were included for analysis if age <18 years at the time of GDD implantation. Failure was defined as an intraocular pressure (IOP) greater than 21 mmHg or IOP reduction <20% or IOP <5 mmHg at 2 consecutive follow-up visits >3 months after implantation, reoperation for glaucoma, or loss of light perception vision. Complications were defined as postoperative events due to the GDD that required additional examination under anesthesia or additional surgery. MAIN OUTCOME MEASURES Survival analyses of surgical failures and complications. RESULTS Over a mean follow-up period of 5.4 years, 58 (38%) of 150 first-time GDD implants failed. Glaucoma associated with acquired conditions had decreased risk for failure when compared with glaucoma secondary to nonacquired systemic diseases (hazard ratio [HR], 12; P = 0.0063), nonacquired ocular anomalies (HR, 12; P = 0.0054), and primary congenital glaucoma (HR, 5.4; P = 0.041). There was an increased risk of failure for first-time tubes in younger patients with a 23% reduction of failure with each 3-year increase in age (HR, 0.77; P = 0.034). A total of 38 (25.3%) of the first-time GDD implantations had a complication. Higher preoperative IOP (5 mmHg increase; HR, 1.2; P = 0.038) and younger age (<3 years; HR, 2.1; P = 0.024; < 2 years, HR, 1.9; P = 0.046) increased the risk of complication. There were 22 second-time GDD implants in the study, of which 11 failed (50%), and increased risk for failure was associated with younger age at the time of implantation (<1 year; HR, 27; P = 0.0053) and concurrent glaucoma-related procedures with or without non-glaucoma anterior segment surgery at the time of implantation (HR, 13; P = 0.0085). CONCLUSIONS Although GDD implantation in children is relatively safe and effective, these data should be interpreted in the context of children's relative longevity. These findings offer an outcome metric to which future novel glaucoma procedures in children can be compared.

Abstract
PURPOSE To evaluate the safety and efficacy of non-penetrating deep sclerectomy with a collagen implant versus trabeculectomy in primary congenital glaucoma. SUBJECTS AND METHODS This was a retrospective interventional comparative non-randomized clinical study that included 80 eyes of 80 children presenting with primary congenital glaucoma under the age of 3 years. Forty eyes have undergone non-penetrating deep sclerectomy (NPDS) and the other 40 eyes have undergone penetrating trabeculectomy. The main outcome measure was the reduction in intraocular pressure (IOP). Secondary outcomes included percentage of patients with complete and qualified success, need for topical antiglaucoma medications, rate of complications, and need for further interventions. Complete success of the surgical outcome was considered an IOP ≤16 mmHg with no antiglaucoma medications. Qualified success was considered an IOP ≤16 mmHg using antiglaucoma medications. RESULTS The mean preoperative IOP was 27.4 ± 6.9 and 28.5 ± 6.6 mmHg in NPDS and trabeculectomy groups, respectively (p = 0.175). At the end of the follow-up period, the mean IOP was 11.2 ± 4.5 and 11.1 ± 3.4 mmHg with a mean reduction of 16.2 and 17.4 mmHg in NPDS and trabeculectomy groups, respectively. At the end of the follow-up period, ie at 36 months postoperative, the complete success rate was 60% (24 eyes) versus 57.5% (23 eyes), the qualified success rate was 25% (10 eyes) versus 25% (10 eyes), the overall success rate was 85% (34 eyes) versus 82.5% (33 eyes), and the rate of failure was 15% (6 eyes) versus 17.5% (7 eyes) in NPDS and trabeculectomy groups, respectively (p = 0.952). Eight cases (20%) of the trabeculectomy group had shallow anterior chamber. None of the NPDS group cases suffered from shallow anterior chamber. CONCLUSION Non-penetrating deep sclerectomy appears to be an efficient and safe surgical alternative to penetrating trabeculectomy in treatment of primary congenital glaucoma. Non-penetrating deep sclerectomy has fewer postoperative complications in comparison to penetrating trabeculectomy with a comparative postoperative reduction in the intraocular pressure and overall success rates.

Abstract
PURPOSE To evaluate the outcomes of primary Ahmed glaucoma valve in refractory secondary glaucoma following congenital cataract surgery, particularly in persistent foetal vasculature. METHOD Retrospective review of paediatric patients after Ahmed glaucoma valve implantation for refractory post-lensectomy glaucoma in a tertiary referral centre in Spain. Surgical complications, additional and/or replacements of Ahmed glaucoma valve, intraocular pressure, cup-to-disc ratio, glaucoma medications and final visual acuity were studied. RESULTS A total of 29 eyes, 41% with persistent foetal vasculature and 59% with non-persistent foetal vasculature were included with mean follow-up of 105 ± 67 and 74 ± 45 months, respectively, after first Ahmed glaucoma valve implant. Median survival time for the first Ahmed glaucoma valve was significantly lower in persistent foetal vasculature (7.0 ± 3.2 months) compared to non-persistent foetal vasculature (over 129 months), p = 0.001. The cumulative probability of success in persistent foetal vasculature and non-persistent foetal vasculature eyes with Ahmed glaucoma valve were, respectively, 37.5% and 88.2% at year 1 and 28.1% and 71.9% at year 5. Cox regression model suggested persistent foetal vasculature as predictive risk factor of time to Ahmed glaucoma valve failure (hazard ratio: 5.77, p = 0.004). Four eyes developed phthisis bulbi. Mean intraocular pressure prior glaucoma surgery was 32.66 ± 6.73 mmHg and decreased to 16.54 ± 2.75 mmHg (p < 0.001) at final visit. The most frequent early postoperative complication was severe hypotony (32.6%) which tended to be self-limiting. Vitreous haemorrhage was associated with persistent foetal vasculature (p = 0.024). Ahmed glaucoma valve replacements after complications and additional Ahmed glaucoma valve implantations due to unsatisfactory intraocular pressure were more common in the persistent foetal vasculature group. CONCLUSION Eyes with persistent foetal vasculature and secondary glaucoma after congenital cataract surgery followed by AGV implantation had a higher number of complications and a decreased probability of success compared to the non-persistent foetal vasculature group. Both groups achieved a significant decrease in intraocular pressure; thus, Ahmed glaucoma valve may be considered as first-line treatment in refractory glaucoma following congenital cataract surgery.

Abstract
INTRODUCTION Trabeculotomy and combined trabeculotomy-trabeculectomy (CTT) are major surgical options for primary congenital glaucoma (PCG). However, it is unclear which of these two surgical procedures should be recommended as the optimum first-line treatment for PCG. This trial aims to determine whether the outcomes of trabeculotomy are non-inferior to those of CTT in moderate PCG with a horizontal corneal diameter (HCD) of 12-14 mm. METHODS AND ANALYSIS This is a 3-year, non-inferiority, prospective, randomised controlled trial. We plan to recruite 248 participants (aged ≤3 years) with PCG with an HCD of 12-14 mm from the Department of Glaucoma, Zhongshan Ophthalmic Center, Guangzhou, China. One eye per participant will be randomly (1:1) assigned to receive trabeculotomy or CTT. The primary outcome is the 3-year postoperative success rate in lowering intraocular pressure (IOP), and the secondary clinical outcomes will include IOP reduction, visual acuity, HCD, central corneal thickness, axial length, cup-disc ratio, refractive error and postoperative complications. Data will be analysed by the intention-to-treat principle. ETHICAL APPROVAL AND DISSEMINATION The study protocol has been approved by the ethics committee of Zhongshan Ophthalmic Center (2014MEKY023) and the '5010 Plan' evaluation committee at Sun Yat-Sen University, Guangzhou, China. The results will be disseminated in international academic meetings and published in peer-reviewed journals.

Abstract
Primary congenital glaucoma (PCG) continues to be an important cause of visual impairment in children despite advances in medical and surgical treatment options. The progressive and blinding nature of the disease, together with the long lifespan of the affected population, necessitates a thorough understanding of the pathophysiology of PCG and the development of long-lasting treatment options. The first part of this review discusses the genetic features and makeup of this disorder, including all currently identified genetic loci (GLC3A, GLC3B, GLC3C and GLC3D) and relevant protein targets important for trabecular and Schlemm canal dysgenesis. These target molecules primarily include CYP1B1, LTBP2, and TEK/Tie2 proteins. Their potential roles in PCG pathogenesis are discussed with the purpose of bringing the readers up to date on the molecular genetics aspect of this disorder. Special emphasis is placed on functional implications of reported genetic mutations in the setting of PCG. The second part of the review focuses on various modifications and refinements to the traditional surgical approaches performed to treat PCG, including advances in goniotomy and trabeculotomy ab externo techniques, glaucoma drainage implant surgery and cyclodiode photocoagulation techniques that ultimately provide safer surgical approaches and more effective intraocular pressure control in the 21st century.

Abstract
AimTo report the intermediate-term outcomes of Aurolab aqueous drainage implant (AADI) surgery in paediatric eyes with refractory glaucoma.MethodsCase records of patients below 18 years, who underwent AADI surgery between 2012 and 2015 with >2 years follow-up, were analysed. The intraocular pressure (IOP), visual acuity, number of antiglaucoma medications, complications and resurgery if any were recorded at baseline, day 1and then at months 1, 3, 6, 9, 12, 18, 24 and at the last visit. Failure was defined as IOP >18 mm Hg or not reduced by at least 30% below baseline, IOP ≤5 mm Hg on two consecutive follow-up visits after 3 months, reoperation for a complication or loss of light perception vision.Results101 eyes of 101 patients were included with a mean age of 10.4±4.7 years at the time of surgery and a mean follow-up of 40.9±15.1 months. Glaucoma following cataract surgery was the most common type of glaucoma (n=31, 30%), followed by primary congenital glaucoma (n=29, 29%). The cumulative probability of failure was 15.8% (95% CI 10.1% to 24.5%) at 1 year, 22.7% (95% CI 15.7% to 32.2%) at 2 years, 42.5% (95% CI 32.6% to 53.9%) at 3 years and 62.1% (95% CI 49.5% to 74.8%) at the 4 years time point.ConclusionThe AADI showed excellent success until 2 years after surgery in paediatric eyes after which failure rates increased. Further prospective studies with longer follow-up are required to evaluate the long-term success of the AADI for paediatric glaucomas.

Abstract
Purpose To determine the presence of burden and positive aspects among caregivers of patients with pediatric glaucoma (PG) and to establish whether they were influenced by the characteristics of the caregivers and the patients. Method This study was designed to be cross-sectional and descriptive. The Chinese version of the Caregiver Burden Inventory (CBI) and the Positive Aspects of Caregiving (PAC) questionnaires were used to evaluate the caregivers. The demographic data of the enrolled participants were also collected. The CBI and the PAC scores were analyzed in relation to each other and different characteristics of the patients with PG and their caregivers through a generalized linear regression model. Result Most of enrolled 57 caregivers were found to act with a moderate level of burden and benefits. The emotional subscale score of the CBI is negatively related to the aggregate score of the PAC and to that of outlook on life. Moreover, patients with a longer duration of disease and caregivers who were female, had jobs, had lower education levels, and had lower household incomes have qualities that are positively related to the summary score of the CBI. However, no factors we collected were significantly related to the PAC score. Conclusion The results suggest that caregivers perceive positive and negative experiences in the care and support of patients suffering from PG. In addition, we should pay more attention to the caregivers with a high risk of experiencing caregiver burden, especially females with jobs and also with lower incomes and lower levels of education.
