Abstract
Purpose Mutations in the genes encoding type IV collagen alpha 1 (COL4A1) and alpha 2 (COL4A2) cause a multisystem disorder that includes ocular anterior segment dysgenesis (ASD) and glaucoma. We previously showed that transforming growth factor beta (TGFβ) signaling was elevated in developing anterior segments from Col4a1 mutant mice and that reducing TGFβ signaling ameliorated ASD, supporting a role for the TGFβ pathway in disease pathogenesis. Here, we tested whether altered TGFβ signaling also contributes to glaucoma-related phenotypes in Col4a1 mutant mice. Methods To test the role of TGFβ signaling in glaucoma-relevant phenotypes, we genetically reduced TGFβ signaling using mice with mutated Tgfbr2, which encodes the common receptor for all TGFβ ligands in Col4a1+/G1344D mice. We performed slit-lamp biomicroscopy and optical coherence tomography for qualitative and quantitative analyses of anterior and posterior ocular segments, histological analyses of ocular tissues and optic nerves, and intraocular pressure assessments using rebound tonometry. Results Col4a1+/G1344D mice showed defects of the ocular drainage structures, including iridocorneal adhesions, and phenotypes consistent with glaucomatous neurodegeneration, including thinning of the nerve fiber layer, retinal ganglion cell loss, optic nerve head excavation, and optic nerve degeneration. We found that reducing TGFβ receptor 2 (TGFBR2) was protective for ASD, ameliorated ocular drainage structure defects, and protected against glaucomatous neurodegeneration in Col4a1+/G1344D mice. Conclusions Our results suggest that elevated TGFβ signaling contributes to glaucomatous neurodegeneration in Col4a1 mutant mice.

Abstract
INTRODUCTION Primary congenital glaucoma causes vision loss if intraocular pressure is uncontrolled. Nonpenetrating deep sclerectomy is effective in treating primary congenital glaucoma. However, the effects of inadvertent trabeculodescemetic window perforation remain unclear. METHODS This retrospective cohort study included patients with primary congenital glaucoma who underwent nonpenetrating deep sclerectomy between 2014 and 2021. The perforation group had intraoperative trabeculodescemetic window perforations; the non-perforation group did not. The primary outcome was intraocular pressure between the groups over 15 months. The secondary outcomes included surgical success and complications. RESULTS The study included 74 eyes of 44 patients. The cohort comprised 31 perforated and 43 non-perforated eyes. Both groups showed significant intraocular pressure reduction without significant between-group differences in complete (68 vs. 77%), qualified (19 vs. 9%), or failed (13 vs. 14%) treatments. The median intraocular pressure decreased from 39 to 14 mmHg in the perforation group and 35 to 12 mmHg in the non-perforation group. Of the 74 treated eyes, 68 (92%) showed no complications. CONCLUSIONS An inadvertent trabeculodescemetic window perforation during nonpenetrating deep sclerectomy for primary congenital glaucoma did not significantly affect intraocular pressure outcomes compared to non-perforated cases over 15 months. Nonpenetrating deep sclerectomy reduced intraocular pressure regardless of intraoperative perforation in patients with primary congenital glaucoma. Perforation of the trabeculodescemetic window was associated with a low incidence of postoperative complications.

Eur J Pediatr 2024; 183:885-895. [PMID: 37864600 DOI: 10.1007/s00431-023-05262-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 09/22/2023] [Accepted: 10/05/2023] [Indexed: 10/23/2023]
Abstract
The purpose of the study was to determine the associations of self-perception, motor skills, and clinical features of young school-age children with glaucoma (CG). This is a cross-sectional observational study. Children from preschool to second grade, including CG (N = 19), children with amblyopia (CA, N = 28), and controls (N = 32), completed the Manual Dexterity and Aiming and Catching Scales of the Movement Assessment Battery for Children-2nd edition (MABC-2), including Manual Dexterity, Aiming and Catching, and Balance. CG, CA, and their parent completed the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children, respectively, assessing the child's cognitive competence, peer acceptance, physical competence, and maternal acceptance. The Kruskal-Wallis H test and Bonferroni post hoc test compared motor skills among groups. Spearman's correlation analysis evaluated the correlations between motor skills, self-perception, and clinical features. The CG reported lower peer acceptance than CA (P = 0.040), and the parents of CG reported lower cognitive competence than CG reported (P = 0.046). Compared with controls, CG had worse performance of Aiming and Catching, and Balance (P = 0.018 and P = 0.001), and CA had worse performance of Balance (P = 0.009). The motor skills were comparable between CG and CA. For CG, older age correlated with worse competence of Aiming and Catching (r = - 0.620, P = 0.005), better best-corrected visual acuity of better-seeing eye correlated with higher competence of Manual Dexterity and Balance (r = - 0.494, P = 0.032, and r = - 0.516, P = 0.024), and longer duration of glaucoma correlated with worse competence of Manual Dexterity (r = - 0.487, P = 0.034). CONCLUSION Glaucoma and amblyopia have significant negative impacts on children's daily motor skills. The acuity of a better-seeing eye is an important factor influencing motor movement. TRIAL REGISTRATION ClinicalTrials.gov identifier, ChiCTR2100050415. WHAT IS KNOWN • The state of mental health in early childhood influences the development of their future personality and physical development. The prognosis and management of glaucoma may seriously impair the mental health development of the affected children. However, the exploration of psychological aspects and motor movement of childhood glaucoma was limited. WHAT IS NEW • Children with glaucoma have impaired motor skills and self-perception development, especially in terms of peer socialization.

Long-term outcomes of cyclophotocoagulation in refractory pediatric glaucoma: treatment response and success in 262 eyes. J AAPOS 2024; 28:103811. [PMID: 38219922 DOI: 10.1016/j.jaapos.2023.11.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 11/01/2023] [Accepted: 11/04/2023] [Indexed: 01/16/2024]
Abstract
PURPOSE To report the surgical success and response to treatment for children undergoing cyclophotocoagulation (CPC) for refractory pediatric glaucoma. METHODS The medical records of children with a diagnosis of glaucoma who underwent a first CPC between May 2000 and May 2020 were reviewed retrospectively. The cumulative probability of success was assessed. For definition 1, treatment success was defined as IOP ≤21 mm Hg at all the visits after the first 3 months without the need for additional glaucoma surgery or repeat CPC. For definition 2, repeat CPC did not constitute failure. RESULTS Of 300 eyes that underwent CPC, we identified 262 eyes eligible for inclusion. The mean age at time of first treatment was 5.33 ± 5.03 years, with a mean follow-up of 4.3 ± 4.2 years (31 eyes having at least 10 years of follow-up). The success rates for definitions 1 and 2 were 26.7% (95% CI, 21.7%-32.4%) and 46.2% (95% CI, 40.2%-52.3%), respectively. Older age was associated with a lower risk of failure after both single CPC (HR, 0.92; 95% CI, 0.88-0.96; P < 0.001) and multiple CPCs (HR, 0.95; 95% CI, 0.90-1.00, P = 0.073). Of the 262 eyes, 107 (41%) had sustained IOP-lowering with a single treatment and 56 (21%) with multiple treatments; 35 (13%) had a transient response, and 64 (24%) had no response. CONCLUSIONS Glaucoma control through CPC often requires multiple treatments, with around a quarter of children responding suboptimally. Older children are more likely to exhibit successful IOP lowering.

Abstract
Glaucoma secondary to Peters anomaly is an important factor affecting visual prognosis, but there are few reports on the condition. This study aimed to investigate the characteristics of glaucoma associated with Peters anomaly and glaucoma surgery outcomes. This retrospective study included 31 eyes of 20 patients with Peters anomaly. Peters anomaly was classified into three stages: Stage 1, with a posterior corneal defect only; Stage 2, a corneal defect with iridocorneal adhesion; and Stage 3, a corneal defect with lens abnormalities. The associations between glaucoma and anterior segment dysgenesis severity, visual prognosis, and glaucoma surgery outcomes were analyzed. Sixteen eyes of ten patients developed glaucoma. Stage 1 Peters anomaly had no glaucoma, 52% of Stage 2 had glaucoma, and 75% of Stage 3 had glaucoma. Of the 16 eyes with glaucoma, 11 underwent surgery. Eight of these eleven eyes achieved intraocular pressure (IOP) control. Five of the nine eyes that underwent trabeculotomy (TLO) succeeded, and none had corneal staphyloma. Three of the four eyes for which TLO was ineffective had corneal staphyloma (p = 0.0331). Patients with Peters anomaly are more likely to develop glaucoma as anterior segment dysgenesis progresses, and the effect of TLO is limited if corneal staphyloma is present.

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
PURPOSE The PAUL® glaucoma implant (PGI) is a novel glaucoma drainage device, which has not been previously reported in paediatric glaucoma management. This study aims to evaluate the safety and effectiveness of the PGI in a paediatric cohort. METHODS A retrospective evaluation of 25 cases of paediatric PGI surgery (age 8 months to 16 years) was performed at Manchester Royal Eye Hospital between September 2019 and July 2020. Primary outcome measures included failure (intraocular pressure (IOP) > 21 mmHg or < 20% reduction of IOP, removal of the implant, further glaucoma intervention or visual loss. Secondary outcomes included mean IOP, mean number of medications, logMAR visual acuity and complications. RESULTS Eleven eyes (48%) had a complete success and achieved an unmedicated IOP < 21 mmHg, and 21 eyes (84%) had a qualified success (with or without medications). Four failures were observed, 2 due to hypotony and 2 underwent further surgery (gonioscopy-assisted transluminal trabeculotomy). The mean preop IOP was 30.9 ± 5.9 mmHg (n = 25), falling to 13.5 ± 6.8 mmHg at 1 month, 17.9 ± 7.2 mmHg at 3 months, 13.4 ± 5.1 mmHg at 6 months, 13.2 ± 4.9 mmHg at 12 months and 11.8 ± 4.6 mmHg at 24 months. The mean change in IOP from the preoperative visit to the last visit was a reduction of 19.1 ± 7.7 mmHg. A significant reduction in the number of medications and IOP was demonstrated after PGI (p < 0.0001). Nine patients required removal of the intraluminal Prolene stent from the PGI for further pressure lowering. CONCLUSION The one- to two-year results demonstrate paediatric PGI has high qualified success rates and effectively reduces IOP and the need for glaucoma medical therapy.

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.

PRCIS This study demonstrates that a baseline corneal diameter >12.25, initial age <4 months at diagnosis, higher baseline IOP than 24 mm Hg, bilaterality, or inability to perform circumferential trabeculotomy, increases the risk of surgical failure of trabeculotomy in patients with primary congenital glaucoma (PCG). PURPOSE The aim of this study was to identify clinical predictive factors for surgical failure and to evaluate potential prognostic factors affecting surgical success in patients with PCG who underwent trabeculotomy. PATIENTS AND METHODS The medical charts of 123 eyes of 75 patients who underwent trabeculotomy surgery for the treatment of PCG were retrospectively reviewed. At baseline and each visit, intraocular pressure (IOP), corneal diameter, cup to disc ratio, axial length, number of medications, and need for further glaucoma surgery were noted. Surgical success was defined as an IOP ≤18 mm Hg and 20% IOP reduction from baseline with (qualified) or without (complete) medication and without any further IOP-lowering surgery. RESULTS The mean age at surgery was 4.2±6.6 months and the mean follow-up time was 60.0±37.6 months. The receiver operating characteristic curve showed 4 following best cutoff values to predict surgical failure: the first for age at surgery was 4.5 months; the second baseline IOP was 24.0 mm Hg; the third for baseline cup to disc ratio was 0.4; and the fourth for baseline corneal diameter was 12.25 mm. Multivariate logistic regression analysis revealed that baseline IOP more than 24 mm Hg increased the risk of surgical failure by 2 times, baseline mean corneal diameter >12.25 mm did by 4.2 times, younger age than 4 months did by 2.5 times, bilaterality did by 1.5 times. CONCLUSIONS A higher baseline IOP, younger age, larger corneal diameter, and bilaterality were identified as risk factors for trabeculotomy failure in congenital glaucoma. The presence of one or more of these should be considered in the decision-making process when considering surgical options to manage glaucoma in these patients.

Abstract
Abstract
Purpose
To compare the outcomes and complications of different surgical interventions for secondary glaucoma in pediatric uveitis.
Methods
Systematic review following the PRISMA standards. Main inclusion criteria were surgery for secondary glaucoma in pediatric uveitis at a mean age of 16 years or below, a mean follow-up period of at least 1 year after surgery, and at least 10 eyes per surgical intervention per study. We used the GRADE approach to assess study quality. Primary outcomes were intraocular pressure (IOP) and number of IOP lowering medications before and after surgery. Secondary outcomes were success rate and complications.
Results
Fourteen studies fulfilled the inclusion criteria, in which one (n = 11) or more (n = 3) surgical interventions were described, comprising in total six different procedures. According to the GRADE criteria, the quality of the studies was low to very low, in particular because of the small size and the applied study designs. All surgical interventions provided a significant decrease in IOP and number of IOP lowering medications. The success rates during follow-up varied widely, with the lowest rates of success after cyclophotocoagulation. The most frequently reported complications were ocular hypertension, hypotony, and hyphema, with an indication for a reoperation in more than one-third of the cases. Permanent vision loss was infrequently seen and was attributed to prolonged hypotony.
Conclusions
The described surgical interventions are able to prevent blindness by lowering a medically uncontrolled IOP to an acceptable level. Therefore, there is a crucial role for surgical intervention in these children. Based on the present studies, no preferences can be made. Given the reported complications, more research with larger sample sizes and direct comparisons is needed to determine the most successful glaucoma treatment in children with uveitis.

Abstract
PURPOSE To investigate the outcome of viscocanalostomy combined with trabeculotomy (VCO+tbo) in primary congenital glaucoma (PCG) with history of failed trabeculotomy. METHODS In this prospective study, VCO+tbo was performed in 75 eyes of 46 patients with PCG who had not responded adequately to one angle surgery. Success was defined as intraocular pressure (IOP) of 6-21 mm Hg and at least 20% IOP drop at the last postoperative visit with (qualified) or without (complete) glaucoma medications. RESULTS Patients completed a mean follow-up of 31 ± 11 months. Complete success was achieved in 6 eyes (8%); qualified success, in 38 eyes (51%). In the 44 successfully treated eyes, IOP was reduced from a preoperative mean of 29.0 ± 5.8 to 15.7 ± 2.6 mm Hg, and the number of medications dropped from 2.6 ± 0.9 to 2.0 ± 1.0 (P < 0.001). In univariate analysis, the success rate was lower in patients with neonatal onset disease than subjects whose age at onset was 1-12 months (HR = 0.22; 95% CI, 0.05-0.93; P = 0.039). Children whose disease was first diagnosed after 1 year of age responded better than neonatal onset patients but worse than those with age of onset of 1-12 months; however, the difference was not statistically significant. Hyphema occurred in 27 eyes (36%) on day 1 and resolved spontaneously. Iatrogenic cyclodialysis occurred in one eye, which was surgically repaired after 1 month of treatment with cycloplegic agents. CONCLUSIONS In our study cohort, VCO+tbo was associated with successful outcomes in the majority of treated eyes.

Abstract
BACKGROUND Perimetry is important in the management of children with glaucoma, but there is limited evidence-based guidance on its use. We report an expert consensus-based study to update guidance and identify areas requiring further research. METHODS Experts were invited to participate in a modified Delphi consensus process. Panel selection was based on clinical experience of managing children with glaucoma and UK-based training to minimise diversity of view due to healthcare setting. Questionnaires were delivered electronically, and analysed to establish 'agreement'. Divergence of opinions was investigated and resolved where possible through further iterations. RESULTS 7/9 experts invited agreed to participate. Consensus (≥5/7 (71%) in agreement) was achieved for 21/26 (80.8%) items in 2 rounds, generating recommendations to start perimetry from approximately 7 years of age (IQR: 6.75-7.25), and use qualitative methods in conjunction with automated reliability indices to assess test quality. There was a lack of agreement about defining progressive visual field (VF) loss and methods for implementing perimetry longitudinally. Panel members highlighted the importance of informing decisions based upon individual circumstances-from gauging maturity/capability when selecting tests and interpreting outcomes, to accounting for specific clinical features (e.g. poor IOP control and/or suspected progressive VF loss) when making decisions about frequency of testing. CONCLUSIONS There is commonality of expert views in relation to implementing perimetry and interpreting test quality in the management of children with glaucoma. However, there remains a lack of agreement about defining progressive VF loss, and utilising perimetry over an individuals' lifetime, highlighting the need for further research.

Abstract
PURPOSE To evaluate the outcome of trabeculectomy augmented with mitomycin C in primary congenital glaucoma and to document the complications of the procedure in young children. METHODS This was a prospective study of children younger than 2 years with primary congenital glaucoma who were treated with primary trabeculectomy with mitomycin C. After surgery, patients were observed for a minimum of 1 year. Trabeculectomy success was defined as an intraocular pressure (IOP) of 21 mm Hg or less without (absolute success) or with (qualified success) topical antiglaucoma medications. Surgical success was assessed at 1, 6, and 12 months after the procedure. RESULTS Seventy-four eyes of 42 children were included in the current study. The mean age was 11.7 ± 8.5 months. Of the 42 children, 57.2% were male and 42.8% were female. The mean IOP after surgery was significantly lower than the preoperative IOP (P < .0001). Absolute success was observed in 98.6%, 50%, and 27% of eyes at 1, 6, and 12 months, respectively. Qualified success was achieved in 1.4%, 36.5%, and 48.6% of eyes at 1, 6, and 12 months, respectively. Overall success of the procedure was 100% at 1 month but reduced to 86.5% at 6 months and 75.7% at 12 months. In 24.3% of eyes, IOP was not controlled even with adjunctive topical glaucoma medications and was considered a failure. Postoperative complications were shallow anterior chamber (10.8%), collapsed anterior chamber (1.3%), and choroidal detachment (12.0%). Complications were managed conservatively, and 6 eyes needed surgical intervention. CONCLUSIONS Augmented trabeculectomy is a useful primary procedure in children with primary congenital glaucoma. Topical glaucoma medications supplement the success of the procedure. [J Pediatr Ophthalmol Strabismus. 2022;59(3):180-186.].

Abstract
PRCIS Trabeculotomy (T) alone is as safe and effective as combined trabeculotomy-trabeculectomy (TT) in patients with primary congenital glaucoma (PCG) and requires significantly fewer examinations under anesthesia in the postoperative period. PURPOSE The purpose of this study was to compare the outcomes of T and combined TT as the initial surgical procedure for patients with PCG. METHODS In this retrospective study, medical records of patients who had undergone T or TT as the initial procedure for PCG were reviewed. The primary outcome measure was a surgical success, defined as 5≤ intraocular pressure (IOP) ≤21 mm Hg, IOP reduction of at least 20% with no need for further glaucoma surgery. Secondary outcome measures were the number of glaucoma medications and complications. RESULTS A total of 134 eyes from 134 patients with a mean follow-up of 8±6.6 years were included consisting of 106 and 28 eyes, which had undergone T and TT, respectively. Success rates were comparable with both surgical procedures at 1, 2, 3, 4, and 5 years with no statistically significant difference. IOP was significantly decreased from 27.5±4.2 mm Hg preoperatively to 15.62±3.4 mm Hg at the 5-year follow-up visit in the T group and from 25.3±6.5 to 17.1±3.2 mm Hg in the TT group (P=0.1) there was no significant difference between the 2 groups in the number of glaucoma medications (P=0.2). Patients in the T group required significantly fewer examinations under anesthesia than the TT group (7.3±4.4 vs. 10.1±3.9, P=0.04). CONCLUSION Trabeculotomy alone seems as effective as combined trabeculotomy-trabeculectomy and may significantly reduce exposure to anesthesia in primary congenital glaucoma 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
PRCIS The PAUL Glaucoma Implant is an effective intraocular pressure (IOP)-lowering device with an acceptable safety profile. Its design as a nonvalved device with a small tube diameter using a vicryl ligation suture around the tube that is posteriorly reabsorbed instead of an ab luminal stent makes it an option in cases selected for glaucoma drainage device implantation. PURPOSE The aim was to determine the 1-year efficacy and safety of PAUL Glaucoma Implant using a uniform, standardized surgical procedure. MATERIALS AND METHODS Retrospective, cohort study. Patient charts were screened between December 2018 and January 2020, with inclusion requiring a minimum follow-up of 12 months. Primary outcome was IOP-lowering at 12 months, with surgical success defined as ≤18 mm Hg and at least 30% reduction and higher than 5 mm Hg. Absolute success was achieved if no IOP-lowering medication was needed and qualified success if otherwise. Safety outcomes were also analyzed. A standardized protocol was followed in all cases, which included mitomycin C application and 1 vicryl ligation of the tube. RESULTS A total of 24 eyes from 21 patients fulfilled inclusion criteria. Median patient age at time of surgery was 42 years (range: 1 to 76 y). IOP decreased from 31.4 (10.0) mm Hg in preoperative period to 12.5 (4.3) mm Hg in the last follow-up (P<0.001). Qualified success criteria were fulfilled by 75% of cases, while absolute success was 33%. The mean number of IOP-lowering drugs used before surgery was 3.0 and 0.9 at the 12-month visit (P<0.001). No postoperative hypotony requiring intervention was recorded. CONCLUSIONS PAUL Glaucoma Implant appears to be a safe and effective glaucoma drainage implant for the treatment of moderate and advanced glaucoma.

Abstract
After a long period of little change, glaucoma surgery has experienced a dramatic rise in the number of possible procedures in the last two decades. Glaucoma filtering surgeries with mitomycin C and glaucoma drainage devices remain the standard of surgical care. Other newer surgeries, some of which are minimally or microinvasive glaucoma surgeries, target existing trabecular outflow, enhance suprachoroidal outflow, create subconjunctival blebs, or reduce aqueous production. Some require the implantation of a device such as the iStent, Hydrus, Ex-PRESS, XEN and PRESERFLO, whilst others do not-Trabectome, Kahook dual blade, Ab interno canaloplasty, gonioscopy-assisted transluminal trabeculotomy, OMNI and excimer laser trabeculotomy. Others are a less destructive variation of an established procedure, such as micropulse transscleral cyclophotocoagulation, endoscopic cyclophotocoagulation and ultrasound cycloplasty. Cataract surgery alone can be a significant glaucoma operation. These older and newer glaucoma surgeries, their mechanism of action, efficacy and complications are the subject of this review.

Abstract
Childhood glaucoma represents a heterogenous group of rare ocular conditions that may result in significant sight threatening complications related to elevated intraocular pressure (IOP). It can be classified as either primary or secondary and the latter may have systemic associations. This review will be based on the work of the childhood glaucoma research network (CGRN) and will focus on the diagnosis and management of the most common types of childhood glaucoma. These include primary congenital glaucoma (PCG) and juvenile open angle glaucoma (JOAG) as well as secondary causes of glaucoma associated with non-acquired ocular anomalies (Axenfeld-Rieger anomaly; Peters anomaly and Aniridia), glaucoma associated with systemic disease (Sturge Weber syndrome and Neurofibromatosis), those due to acquired conditions (Uveitic glaucoma, trauma and tumours) and importantly glaucoma following cataract surgery.

Abstract
BACKGROUND To describe the clinical characteristics and treatment of primary childhood glaucoma at Queen Elizabeth Central Hospital in Blantyre, Malawi. METHODS A retrospective case notes review was undertaken of all medical records of patients aged less than 16 years with a diagnosis of primary glaucoma according to the Childhood Glaucoma Research Network Classification (CGRN) who presented from January 2016 to December 2018. The parameters extracted from the case files included age at presentation, sex, type of glaucoma, presenting complaints, laterality of ocular involvement, examination findings and the treatment modality instituted. The Mann-Whitney test was used to investigate factors associated with the intraocular pressure (IOP) in eyes that had a higher presenting IOP value compared to contralateral eyes. RESULTS A total of 45 subjects (80 eyes) were identified, 42 with primary congenital glaucoma (PCG) and 3 with juvenile open angle glaucoma (JOAG). The mean age for the population was 2.6 years (S.D ± 3.7) and most of the patients were male, with a male-female ratio of 2:1. The majority of patients had bilateral disease (n = 35, 77.8%) with the commonest presenting complaint being a whitish appearance of the eye (57.5%). The eyes studied had a mean IOP of 30.1 mmHg (CI 27.4-32.9), a mean horizontal corneal diameter (HCD) of 13.6 mm (CI 13.1-14.2) and a mean cup-disc-ratio `(CDR) of 0.73 (CI 0.66-0.79). In addition, 62 eyes (77.5%) had corneal haze on examination. Most patients (n = 59, 73.8%) underwent a combined trabeculotomy - trabeculectomy surgery within the study period. The median presenting IOP was significantly higher with JOAG compared to PCG (P = 0.02). CONCLUSION PCG was the most common primary childhood glaucoma at Queen Elizabeth Central Hospital and most patients presented with bilateral eye involvement. Most of the eyes had corneal haze and JOAG was associated with a higher presenting IOP compared to PCG. Further studies to investigate the outcomes of combined trabeculotomy - trabeculectomy surgery in primary childhood glaucoma in Malawi are recommended.

Fontana L, Neri A. Microcatheter-Assisted Circumferential Trabeculotomy in Primary Congenital Glaucoma: Long-Term Clinical Outcomes. J Clin Med 2022; 11:jcm11020414. [PMID: 35054107 PMCID: PMC8779731 DOI: 10.3390/jcm11020414] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 01/03/2022] [Accepted: 01/12/2022] [Indexed: 02/06/2023] Open
Abstract
Purpose: The purpose of this study was to report the long-term efficacy and clinical outcomes of microcatheter-assisted circumferential trabeculotomy (MCT) in children with primary congenital glaucoma (PCG). Methods: This is a single-center retrospective study including consecutive children with PCG who underwent MCT with > two years follow up. The primary outcome was surgical success, defined as intraocular pressure (IOP) ≤ 21 mmHg with (qualified) or without (complete) medications, measured at six months, one year, and then annually. Secondary outcomes were visual acuity (VA), refraction, axial length (AXL), complications, reinterventions, and number of medications. Results: Twelve eyes of ten patients were included. In eight children only one eye was affected. The mean ± standard deviation (SD) age at surgery was 6.3 ± 4.1 months. The mean postoperative follow-up was 66 ± 35 months. The mean IOP was 34.3 ± 9.6 mmHg preoperatively and 14.6 ± 2.3 mmHg postoperatively at the last visit (p < 0.001). Complete success was achieved at all time points in 10 out of 12 eyes, while 2 eyes had a qualified success. At three years of age, the mean VA of the operated eyes was 0.25 ± 0.12 logMAR, the mean spherical equivalent was −0.78 ± 1.43 diopters, and the mean AXL was 23.78 mm. Transient hyphema was the only complication observed. None of the children required additional glaucoma surgery. Conclusions: Circumferential trabeculotomy for PCG effectively lowers the IOP at more than two years after surgery. Following this procedure, the prognosis for the visual function is good, and the refractive error is low. Postoperative complications were not significant.

Abstract
Purpose To evaluate different pre-operative variables on the success of combined trabeculotomy–trabeculectomy (CTT) surgery in patients with primary congenital glaucoma (PCG) to predict those at higher risk for surgical failure and for proper parent counseling. Patients and Methods Sixty-three eyes of patients with PCG were treated either with CTT without augmentation, or CTT augmented with mitomycin-C (0.2 mg/mL) in both subconjunctival space and under scleral flap for 3 minutes, or with CTT augmented with a collagen implant under both the scleral flap and the conjunctiva. Cases showed surgical failure was reported and evaluated in relation to different pre-operative variables. Results Complete success (IOP ≤21 mmHg) was achieved in 52 cases (82.5%). Cumulative success probability was calculated using Kaplan-Meier survival analysis, proving that higher pre-operative intraocular pressure (IOP) was associated with higher failure rates (28.6% for pre-operative IOP ≥30 mmHg versus 4.8% for IOP <30 mmHg), with P value = 0.007. Conclusion CTT is an effective surgical intervention in PCG patients without sight threatening complications. Univariate survival analysis showed higher rates of surgical failure in patients with higher pre-operative IOP, while other pre-operative variables were irrelevant.

Abstract
Aim To determine the long-term outcomes of a cohort of complex patients with
primary congenital glaucoma, aniridia and anterior segment dysgenesis. Methods Retrospective consecutive series between 1990–2021 in two UK tertiary
centres: Guy's and St Thomas’ NHS Foundation Trust and King's College
Hospital NHS Foundation Trust. We recorded the number and types of surgical
and laser treatments along with preoperative and postoperative data,
including intraocular pressures (IOP) and anti-glaucoma medications. Results A total of 41 eyes of 21 patients were included. Primary diagnoses were
primary congenital glaucoma in 16 eyes (39.0%), aniridia in 14 eyes (34.2%),
and anterior segment dysgenesis in 8 eyes (19.5%). Sixteen eyes (39.0%) had
one or more glaucoma surgery or laser procedures for advanced glaucoma, and
the long-term follow-up was 12.8 ± 3.6 years. There was a significant
decrease in postoperative IOP (mmHg) at 3 months (16.5 ± 1.6;
p = 0.0067), 6 months (18.7 ± 2.1;
p = 0.0386), 12 months (18.6 ± 1.7;
p = 0.0229), 3 years (14.7 ± 1.2;
p = 0.0126), 5 years (15.5 ± 1.8;
p = 0.0330) and 10 years (15.4 ± 2.3;
p = 0.7780), compared to preoperatively (24.1 ± 2.6).
Surgical success (complete and qualified) was 62.5%, 50.0%, 43.8%, 46.2%,
45.5% and 28.6% at 3 months, 6 months, 12 months, 3 years, 5 years and 10
years, respectively. There was no significant change in the number of
anti-glaucoma drugs postoperatively (p > 0.05). Four
eyes (25.0%) had postoperative complications (hyphaema, hypotony) that
resolved after conservative management. Conclusions Surgical management of these complex eyes with advanced glaucoma is
challenging. Overall, the cohort had good surgical outcomes with a
significant decrease in IOP by 36.1% after long-term follow-up.

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
Aim and objective Report three different solutions in case of XEN-augmented Baerveldt fails. Background Drainage devices have been used for refractory pediatric glaucoma. To avoid early hypotony and corneal damage, Mermoud et al. introduced the augmentation of a XEN implant with a Baerveldt tube. In some cases, this technique fails to lead to a high intraocular pressure (IOP) and surgical revision. Case description Three cases of children with this combined implant needed surgical revision due to high IOP. Three different approaches were performed: XEN replacement in one case, stretching the Baerveldt's tube into the anterior chamber (AC) in the second case, and explant of the device followed by an implant of a new Baerveldt-250 in the same quadrant in the third case. Successful control of IOP (>18 mm Hg) was achieved in all patients under no topical treatment. Conclusion Despite the attractiveness of the XEN-augmented Baerveldt implant in refractory pediatric glaucoma as an alternative to conventional surgery, we have to learn how to deal with failures. Three different approaches are presented with good short-term results. The long-term efficacy is yet to be assessed. Clinical significance Describe three possible options when faced with a need for surgical revision in XEN-augmented Baerveldt implant. How to cite this article José P, Abegão Pinto L, Teixeira FJ.

Abstract
PURPOSE To report the corneal tomographic characteristics of eyes that had surgery for controlled primary congenital glaucoma (PCG) and to compare it with an age-matched group of normal children. METHODS The study was conducted on 44 (24 right) eyes of 27 children (18 boys) who had surgery for PCG and 60 (31 right) eyes of 32 age-matched control children (9 boys). Children with PCG had a thorough ophthalmic examination and the demographic and medical and surgical history was retrieved from the patients' clinical chart records. After clinical examination, the study participants underwent Scheimpflug imaging using the Pentacam (Oculus Optikgeräte GmbH). RESULTS Both study and control children were approximately 9 years of age at the time of the study (P = .39). The eyes with PCG had a spherical equivalent mean ± standard deviation of -4.70 ± 3.50 diopters (D). Eyes with PCG demonstrated a cylinder of -2.80 ± 2.10 D, flatter corneas than control eyes (P = .0002 and .0012 for flat and steep keratometry, respectively), and statistically significantly higher astigmatism (P = .011) and thinner corneas, both at pupil center (P < .001) and thinnest location (P < .001). There was a statistically significant negative correlation between the postoperative axial length (at the time of the scan) and each of the Scheimpflug parameters flat keratometry (P = .002), steep keratometry (P = .003), pachymetry at pupil center (P = .01), and pachymetry at thinnest location (P = .009). CONCLUSIONS The eyes of patients with PCG have thinner, flatter, and more astigmatic corneas than the eyes of age-matched control children. [J Pediatr Ophthalmol Strabismus. 2021;58(4):218-223.].

Abstract
PRECIS Mitomycin was used with Ahmed valve implantation in 81 eyes of 63 children. After 5 years, probability of intraocular pressure (IOP) control without glaucoma medication was 35±6%; 57% achieved IOP control with topical medications after 10 years. PURPOSE The purpose of this study was to determine the long-term outcomes of Ahmed glaucoma valve (AGV) implantation with intraoperative application of mitomycin-C (MMC) for the treatment of childhood glaucoma. METHODS Retrospective review of children undergoing AGV implantation with subtenon application of MMC between 2000 and 2019. We defined surgical success as a final IOP of 5 to 21 mm Hg with no glaucoma medication, no subsequent glaucoma surgery, and no severe complication. Qualified success was defined if the above criteria were met with topical antiglaucoma medication. RESULTS Eighty-one eyes of 63 patients were included. The probability of complete success was 72±5% (63% to 83%) at 1 year, 58±6% (48% to 70%) at 2 years, and 35±6% (25% to 48%) at 5 years. The probability of qualified success was 92±3% (87% to 98%) at 1 year, 79±5% (70% to 89%) at 5 years, 57±7% (44% to 73%) at 10 years, and 39±9% (24% to 62%) at 14 years. The IOP was reduced by an average of 10.7±9 mm Hg from preoperative visit to the last follow-up, and the number of medications decreased from 3.0±1.4 to 1.5±1.4 after implantation. CONCLUSIONS A significant proportion of patients achieved long-term IOP control without glaucoma medication. The majority achieved IOP control with additional topical antiglaucoma medications. When compared with existing AGV implantation in childhood literature, the use of MMC appears to lengthen the drop-free (complete success) duration, as well as the long-term IOP control with topical medications.

Abstract
PURPOSE To report on the changes in the natural crystalline lens in primary congenital glaucoma (PCG) eyes that had undergone previous combined angle-filtering surgery with antimetabolites. SETTINGS The pediatric ophthalmology unit of the ophthalmology department of Alexandria Main University Hospital. DESIGN A retrospective chart review. METHODS A retrospective chart review of patients presenting with and operated (by combined angle-filtering surgery with antimetabolites) for PCG in the period from 2005 to 2018. Any lens pathology was noted as well as the management and the outcome. RESULTS The records of 422 children (613 eyes) were reviewed. Lens pathology was noted in 54 (8.8%) eyes. Abnormalities in lens clarity (cataract) were detected in 31 (56%) eyes, and abnormalities in lens position (subluxation) were detected in 24 (44%) eyes. Management options included observation (in 28 eyes), lensectomy for aphakia (in 14 eyes), lensectomy with in the bag intraocular lens (IOL) implantation (in 11 eyes), and lensectomy with iris-fixated IOL (in 1 eye). Elevation of intraocular pressure (IOP) occurred in only 4 eyes (of 26 operated eyes, 15.3%) after lens extraction. CONCLUSIONS Changes in the natural crystalline lens clarity and/or position occurred in 8.8% (54 of 613) of PCG eyes operated by combined angle-filtering surgery with antimetabolites. Lens extraction was a relatively safe procedure with only 15% (4 of 26) of eyes suffering an elevation of IOP after lens extraction.

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 To determine the surgical outcomes of bleb needling and the risk factors of failure of needling after failed filtration surgeries in patients with pediatric glaucoma. METHODS The medical records of patients who underwent needling with 5-fluorouracil following filtering surgeries (trabeculectomy, combined trabeculectomy, and trabeculotomy) between January 2012 and December 2016 were retrospectively reviewed. At the 1-year follow-up visit, complete success and qualified success were defined as an intraocular pressure (IOP) of less than 18 mm Hg with and without antiglaucoma medication, respectively. RESULTS Forty-five eyes that underwent needling and fulfilled the study criteria were included in the analysis. The mean age at needling was 9.6 years. The mean time interval between filtration surgery and the first needling procedure was 57.3 days. Thirty-eight of 45 eyes (84.4%) had undergone needling within 3 months after the primary surgery. Cumulative success was achieved in 35 eyes (77.7%) after needling (complete success in 22 eyes and qualified success in 13 eyes). Mean follow-up after needling was 18.9 months. The mean IOP before and after needling was 31.7 ± 9.45 and 16.6 ± 5.68 mm Hg, respectively (P < .00001). Steroid-induced glaucoma (P = .01), high IOP prior to the first filtration surgery (P = .01), and an inability to achieve low IOP (< 9 mm Hg, P = .04) immediately after needling were significant risk factors associated with failure. CONCLUSIONS Bleb needling is an efficient method for lowering IOP after a failed trabeculectomy or combined trabeculectomy and trabeculotomy in the pediatric population.

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.

Am J Ophthalmol 2020; 219:77-86. [PMID: 32569736 DOI: 10.1016/j.ajo.2020.06.017] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 06/09/2020] [Accepted: 06/10/2020] [Indexed: 11/24/2022]
Abstract
PURPOSE To describe the transition from conventional angle surgery (CAS), trabeculotomy with rigid probe or goniotomy, to 360-degree trabeculotomy assisted with microcatheter (MCT). DESIGN Retrospective comparative interventional case series. METHODS Review of consecutive children with glaucoma undergoing angle surgery, including cases with previous surgery, from January 2012 until March 2018 at Moorfields Eye Hospital. Main outcome measure was success rate, defined as intraocular pressure (IOP) ≤21 mm Hg with a minimum of 20% of IOP reduction and no further glaucoma surgery (complete success: without the need of glaucoma drops; qualified success: drops were needed to keep the IOP under control). RESULTS Among the 106 eyes (77 patients) included were 54 MCT and 52 CAS eyes. At last visit, after a single surgery, qualified success was 85% (46 eyes) in MCT and 37% (19 eyes) in CAS. Complete success was 69% (37 cases) in MCT and 23% (12 cases) in CAS. The mean (95% confidence interval) change in axial length after surgery was -0.03 mm (-0.34 to 0.40) for MCT and +1.35 mm (-0.64 to 1.62) for CAS (P < .001). The percentage of IOP reduction was 52.1% in MCT and 45.5% in CAS (P = .1616). Further glaucoma surgery was required in 5.5% (3) in MCT and 63.4% (33) in CAS. At 1 year, 94.3% of MCT cases achieved qualified success compared to 34.6% of CAS (P < .0001). No significant complications were found on either group. CONCLUSION MCT achieved better results with significantly lower reoperation rates. The transition from CAS to MCT can be easily achieved, even in difficult cases or those previously operated.

Abstract
PURPOSE To evaluate the epidemiological features, clinical interventions, and outcomes of paediatric glaucoma in Hong Kong. STUDY DESIGN Retrospective chart review. METHODS Clinical data from the medical records of all patients under 18 years of age diagnosed with glaucoma from January 2008 to December 2017 at a university-affiliated, tertiary referral centre were collected. The patients' demographics, etiological distribution, clinical interventions, and outcomes were analysed. RESULTS A total of 33 subjects (53 eyes) were identified, 30 (49 eyes) of whom were Chinese. Primary glaucoma accounted for 21.2% of subjects, while 78.8% were diagnosed with secondary glaucoma. The most common subtype was juvenile-onset open angle glaucoma, followed by Sturge-Weber Syndrome related glaucoma. The most commonly performed surgical interventions were tube-shunt surgery (Ahmed Glaucoma Valve) and transscleral cyclophotocoagulation. Most eyes had significant reduction in intraocular pressure after medical or surgical intervention, but deterioration of visual acuity remained common. CONCLUSION Most cases of childhood glaucoma in Hong Kong are secondary rather than primary, similar to other regions with low incidence of parental consanguinity. The large proportion of secondary glaucoma which generally has poorer prognosis, is reflected by the frequency of multiple surgery, and a high incidence of visual deterioration despite significant intraocular pressure reduction in most eyes.

Abstract
PURPOSE Little is known about quality of life (QoL) and life satisfaction (LS) of treated primary congenital glaucoma (PCG) patients in adulthood. The purpose of this study was to assess the QoL and LS and their predictors among young adults treated for PCG during early childhood. DESIGN Cross-sectional study. PARTICIPANTS Eighty-two participants with PCG (mean age, 22.5 years; standard deviation [SD], 4.6); 52% were male; 94% bilateral) recruited at L V Prasad Eye Institute. METHODS Participants were asked to complete the 26-item World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire (items related to satisfaction with general health, physical, psychological, social relations, and environmental aspects) and the 5-item Satisfaction with Life Scale (SWLS) in the clinic visit. Clinical data including visual acuity (VA) and visual fields (VFs) were collated from medical records. Rasch analysis was used to optimize the psychometric properties, with higher scores indicating a higher degree of QoL and LS, for both the questionnaires. Linear regression models were used to examine associations between overall QoL and LS (in separate models), and sociodemographic and clinical variables. MAIN OUTCOME MEASURES The QoL and LS were measured using Rasch-transformed scores from the WHOQOL-BREF questionnaire and SWLS, respectively. RESULTS Response rate was 93%. The overall mean (SD) Rasch-scaled scores for QoL were 0.93 (1.11) and 0.87 (1.32) for environment domain and 0.41 (1.56) logits for LS. Better QoL was significantly related to rural residence and higher education in both univariable and multivariable analyses and explained 13% variance. Higher LS was significantly related to marital status, unilateral affliction, and higher education in univariable analyses. However, multivariable regression analysis showed that only marital status was independently associated with higher LS and explained 8.8% of variance. Clinical and treatment variables (VF, surgical interventions, medications) were not independent predictors of QoL/LS. CONCLUSIONS Our results suggest that QoL and LS of treated patients with PCG during adult life are generally good and appear to be driven by factors other than clinical indices. Educational achievement appears to be linked to better QoL and LS, and clinicians should emphasize the importance and need for education in the continued care of these patients.

Abstract
PURPOSE To determine the prognostic factors for poor visual outcomes in childhood glaucoma. METHODS The medical records of patients with childhood glaucoma diagnosed at age 4 years or younger who were treated surgically from 2002 to 2019 at Songklanagarind Hospital, Hatyai, Thailand, were retrospectively reviewed. Glaucoma subtypes, clinical characteristics, final visual acuity, and etiology of visual impairment were recorded. The generalized estimating equation for logistic regression analysis was used to determine prognostic factors for final visual acuity of worse than 20/200. RESULTS Forty-five eyes of 31 patients were included (33.3% had primary glaucoma and 66.7% had secondary glaucoma). At the final visit (mean: 6.8 years), 20.5% had good visual acuity (20/50 or better), 15.9% had fair visual acuity (worse than 20/50 to 20/200), and 63.6% had poor visual acuity (worse than 20/200). The major cause of visual impairment (worse than 20/50) was deprivation amblyopia. Prognostic factors for poor final visual acuity (worse than 20/200) were secondary glaucoma, age at diagnosis of younger than 3 months, and interval to surgery of more than 3 months. Eyes with a final visual acuity of better than 20/200 had higher mean intraocular pressure preoperatively that tended to increase postoperatively and every visit afterward compared to the other group. CONCLUSIONS Two-thirds of eyes with childhood glaucoma ended up with poor final vision. Early surgery to control intraocular pressure, along with amblyopia treatment, should be considered to prevent poor visual outcome. The prognostic factors for poor visual outcome can contribute to parental advice and planning of patient care. [J Pediatr Ophthalmol Strabismus. 2020;57(5):283-291.].

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 assess the long-term results of viscotrabeculotomy in infants with primary congenital glaucoma and to compare its outcome with conventional trabeculotomy. PATIENTS AND METHODS A prospective randomized comparative study included infants with primary congenital glaucoma younger than 2 years. Patients were divided into two groups: viscotrabeculotomy group and conventional trabeculotomy group. Preoperative and postoperative intraocular pressures, corneal diameter, intraoperative and postoperative complications, and success rates were compared between two groups. All the patients were followed up for 5 years. RESULTS The study included 154 eyes of 92 infants distributed randomly among the two groups; 78 and 76 eyes in viscotrabeculotomy and conventional trabeculotomy groups, respectively. In both groups, there was a statistically significant intraocular pressure reduction at all time points of the follow-up periods compared to the preoperative values (p < 0.0001). At 5 years, viscotrabeculotomy group showed significant reduction of the mean postoperative intraocular pressure (49.47%) than conventional trabeculotomy group (48.64%) (p < 0.0001). Intraocular pressure was statistically lower in viscotrabeculotomy starting from 12th month and till the end of the follow-up. At 5 years, the total success rate of viscotrabeculotomy group was 89.74% compared to 85.53% in conventional trabeculotomy group without significant difference (p = 0.487). The postoperative mean values of the cup/disk ratio in viscotrabeculotomy group showed statistically lower values compared to conventional trabeculotomy group (p = 0.019). Postoperative hyphema was statistically higher in conventional trabeculotomy group (p < 0.0001). All eyes that underwent a reoperation before 5 years follow-up were excluded from the statistical workup of the study after reoperation, except for calculation of success/failure. CONCLUSION Viscotrabeculotomy and conventional trabeculotomy proved to be effective in cases of primary congenital glaucoma. Viscotrabeculotomy appeared to have prolonged stability in controlling the intraocular pressure with higher success rates and lower complications.

Abstract
Children comprise a unique population of patients in regard to the diagnostic and therapeutic approach of uveitic glaucoma. The management of glaucoma secondary to uveitis in children is extremely challenging and presents various difficulties, which are associated both with the underlying uveitis and the young age of the patients. The treatment of uveitic glaucoma calls for a thorough and individualized approach, involving both pharmacotherapeutic and surgical modalities. It appears that the efficient control of inflammatory activity plays a significant role in the final visual outcome of these patients. This study aims to review the current literature about the management of uveitic glaucoma in pediatric patients.

Abstract
PURPOSE To compare the visual functioning (VF) and vision-related QoL (VRQoL) of children 8-18 years old treated for primary congenital glaucoma (PCG) and secondary childhood glaucoma. DESIGN Cross-sectional study. METHODS A total of 309 children 8-18 years old treated for PCG and secondary childhood glaucoma between 2000 and 2010 by a single pediatric glaucoma specialist were prospectively enrolled at LV Prasad Eye Institute, Hyderabad, India. Children completed 2 questionnaires, the LV Prasad Functional Vision Questionnaire-II (LVP-FVQ-II), and the Impact of Vision Impairment-Children (IVI-C) questionnaire. Rasch-calibrated scores from both these questionnaires were used to compare the VF and VFQoL between the 2 groups. RESULTS Mean ages of the children were 12.2 and 12.6 years in the PCG (53%, median age at diagnosis = 5 months) and secondary glaucoma groups (47%, median age at diagnosis = 3 years), respectively. A majority (80%) of children had bilateral glaucoma and underwent filtering surgery (83%). Mean better eye logMAR visual acuity (VA) was comparable between PCG and secondary childhood glaucoma groups (0.49 vs 0.52, respectively; P = 0.59). Children with PCG reported significantly better VF and VRQoL than secondary childhood glaucoma patients. Unadjusted and adjusted childhood glaucoma group comparisons revealed secondary childhood glaucoma to be associated with worse VF and VRQoL compared to PCG (difference for VF, -0.83; 95% confidence interval [CI], -1.34 to 0.31; P = 0.002; 0.39; 95% CI, 0.16-0.62; P = 0.001 for VRQoL). CONCLUSIONS Results show that children with treated PCG experience significantly better VF and VRQoL than those with secondary childhood glaucoma, despite comparable VA and IOP.

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
PURPOSE To evaluate the long-term outcome of 'bleb-sparing epithelial exchange' surgery for dysfunctional filtering blebs in paediatric and adult eyes. METHODS Patients who had undergone bleb revision ≥ 5 years back and were on regular follow-up were included. Age, ocular diagnosis, details of primary filtering surgery including mitomycin-C (MMC) usage, indication and year of bleb revision were recorded. After bleb revision, the mean intraocular pressure (IOP), glaucoma medications and best corrected visual acuity (BCVA) up to 5 years were noted. On last review, clinical details, bleb characteristics and swept source anterior segment tomographic (SSOCT) assessment of bleb were recorded. Comparative analysis of paediatric and adult eyes was performed. MAIN OUTCOME MEASURES Change in IOP and BCVA. 'Complete success' was defined as IOP ≥ 6 to ≤ 18mmHg without use of any topical glaucoma medications and 'Qualified success' when ≥ 1 topical glaucoma medication(s) was required. RESULTS A total of 51 eyes of 51 consecutive patients were studied, among which 22 were children. The mean duration between filtering surgery and bleb revision was 4.54 ± 1.53 years in paediatric and 6.48 ± 3.5 years in the adult group, p = 0.04. Children underwent trabeculotomy + trabeculectomy with 0.04% MMC, while adults underwent trabeculectomy with 0.02% MMC. The mean pre-revision IOP was 6.38 ± 2.80 and 6.51 ± 2.78 mmHg in the paediatric and adult group respectively, p = 0.86. At 3 months post-revision, it increased to 11.81 ± 3.48 and 12.75 ± 3.52 mmHg respectively (p < 0.001). At final review, mean IOP of paediatric group was 10.90 ± 2.59 and adult group was 11.86 ± 2.66 mmHg, p = 0.20. At 5 years, complete success was 68.18% and 72.41%, and qualified success was 31.87% and 27.59% in the former and latter group respectively, p = 0.49. No failures were seen. Kaplan-Meier probability at 5 years for IOP target ≤ 18, ≤ 15 and ≤ 12 in children was 95.45%, 63.64% and 50% and in adults 93.10%, 65.52% and 41.38% respectively. BCVA improved up to 1 year in paediatric group, with continued improvement in adults up to 3 years. SSOCT measured bleb height was 0.88 ± 0.37 and 1.32 ± 0.49mm in children versus adults (p = 0.006) and wall thickness, 0.35 ± 0.22 and 0.58 ± 0.24mm respectively, p = 0.008. CONCLUSION Bleb-sparing epithelial exchange is an equally safe and effective technique with good long-term success in both paediatric and adult dysfunctional blebs.

Abstract
PURPOSE To analyse the association between the thickness of the circumpapillary retinal nerve fibre layer (cpRNFL) and the thickness of the inner macular layers with the mean deviation of the visual field (MD) in children with primary congenital glaucoma (PCG). MATERIAL AND METHODS A total of 41 children with PGC were included in the study. They all had a complete ophthalmological examination, including visual acuity, intraocular pressure, funduscopy, Octopus™ visual field, as well as circumpapillar and macular spectral domain optical coherence tomography (SD-OCT). SD-OCT with automated segmentation was used to measure the thicknesses and volumes of the macular retinal nerve fibre layer (mRNFL), ganglion cell layer (GCL), and inner plexiform layer. RESULTS The mean age was 11.2±3.86 years, and the mean MD was 8.85±6.76dB. The visual field was classified as normal in 46% of the patients, and 20% of the patients had a concentrical restriction of the visual field. A positive correlation was found between between the cup-to-disc ratio and the MD, r=0.51 (P=.004). The correlation between the MD and the cpRNFL was r=-0.63 (P<.001), and r=-0.69 (P<.001) with the GCL. CONCLUSIONS Inner macular layers thickness and cpRNFL thickness show a good correlation with the mean deviation of the visual field in children with primary congenital glaucoma.

Long-term surgical outcomes of ab externo trabeculotomy in the management of primary congenital glaucoma. J AAPOS 2019; 23:222.e1-222.e5. [PMID: 31251972 DOI: 10.1016/j.jaapos.2019.05.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 05/07/2019] [Accepted: 05/11/2019] [Indexed: 12/25/2022]
Abstract
PURPOSE To analyze the long-term results of ab externo trabeculotomy with a Harms trabeculotome at a single, tertiary care pediatric hospital. METHODS The medical records of pediatric patients operated on between September 2006 and June 2018 were reviewed retrospectively. Kaplan-Meier analysis was performed, with success defined as postoperative intraocular pressure (IOP) of ≤21 mm Hg, >20% reduction from preoperative IOP, and no need for further glaucoma surgery. Risk factors for failure were identified using Cox proportional hazards ratio. RESULTS A total of 63 eyes of 40 patients were included. The cumulative probability of success rate was 83% at 3 months, 76% at 6, 73% at 12, 72% at 18, and 65% at final visit. Presentation within 3 months of life was associated with a less favorable outcome. Thirty-five eyes (56%) underwent repeat trabeculotomy to treat a different area of the trabecular meshwork because of inadequately controlled IOP after the first session. Of those who needed another session of trabeculotomy, the final success rate was 60.2%. IOP significantly decreased from 29.79 ± 7.67 mm Hg at baseline to 16.13 ± 3.41 mm Hg by final follow-up (P = 0.001). Patients were followed for an average of 85.74 ± 32.95 months. IOP and success rates remained stable 18 months after surgery. CONCLUSIONS In our patient cohort, ab externo trabeculotomy was associated with good long-term results. More extensive trabeculotomy (ie, more than one procedure) was associated with better long-term success rates.

A Case Report of Complete Blockage of a Baerveldt Glaucoma Implant Following Insertion of a 3-0 Supramid Suture. J Glaucoma 2019; 28:e75-e76.

Abstract
PURPOSE The aim of this study was to present a case of a Baerveldt glaucoma implant lumen being completely occluded with a 3-0 Supramid stent suture. PATIENT AND METHODS The patient underwent Baerveldt glaucoma implant surgery with placement of an intraluminal 3-0 Supramid stent suture that acts to restrict flow across the device and reduce the risk of postoperative hypotony. Following suturing of the implant to the sclera, the device was flow tested. No flow was observed through the device tube and a significant ballooning of the tube diameter occurred with increased pressure on the device. The device was explanted from the eye and replaced with a different implant without further postoperative complication. The explanted device was assessed using custom microfluidic equipment in an in vitro environment. RESULTS This phenomenon occurred despite using several different batches of the 3-0 Supramid stent suture and the device had to be removed and replaced with another device without complication. In vitro microfluidic assessment of the device demonstrated no flow across the device tube despite over 150 mm Hg of pressure being exerted on the device. CONCLUSIONS We hypothesize that the blockage occurred at the junction between the device tube and plate and that the ballooning phenomenon observed was due to a defect in the tube wall. This case highlights the importance of flow testing all glaucoma drainage devices before insertion given the variation in manufacturing conditions to avoid the risk of intraoperative complications.

A Long-term Safety Study of Latanoprost in Pediatric Patients With Glaucoma and Ocular Hypertension: A Prospective Cohort Study. Am J Ophthalmol 2018; 196:101-111. [PMID: 30194929 DOI: 10.1016/j.ajo.2018.08.039] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2018] [Revised: 08/28/2018] [Accepted: 08/28/2018] [Indexed: 12/30/2022]
Abstract
PURPOSE The objective was to assess the long-term effect of treatment with latanoprost on ocular development and safety in pediatric patients with glaucoma and ocular hypertension. DESIGN Prospective cohort study. METHODS This was a prospective 3-year cohort study conducted in 14 countries in Europe and South America. Patients aged < 18 years with glaucoma or ocular hypertension were enrolled into either the latanoprost or non-prostaglandin (non-PG) group in this observational study. The primary endpoint was change in best-corrected visual acuity (BCVA) from baseline to 3 years. Several secondary endpoints were evaluated, including corneal thickness and ocular hyperpigmentation. For treatment comparison, analysis of covariance (ANCOVA) was used for continuous endpoints and Fisher exact test was applied for proportion of participants with clinically significant deterioration events. RESULTS A total of 175 patients were enrolled: 102 in the latanoprost group (median follow-up: 36.7 months) and 73 in the non-PG group (median follow-up: 36.1 months). There was no statistically significant difference between the latanoprost and the non-PG groups (aged 5 to <18 years) in BCVA change from baseline (least square mean logMAR difference -0.03 [95% confidence interval: -0.12, 0.06]), corneal thickness, or ocular hyperpigmentation. CONCLUSIONS Latanoprost had an acceptable safety profile with no evidence of inducing clinically meaningful or statistically significant changes in ocular development or ocular hyperpigmentation in pediatric patients with glaucoma and ocular hypertension.

Abstract
PURPOSE To evaluate the effectiveness of microcatheter-assisted trabeculotomy (MAT) to treat primary congenital glaucoma after failed previous glaucoma surgeries. MATERIALS AND METHODS Retrospective, noncomparative, interventional case series conducted at Beijing Tongren Eye Center, China. Outcome measures were compared between 3 groups: successful and complete (≥330 degrees) MAT; successful and partial (<330 degrees) MAT; or cases converted to traditional trabeculotomy when the Schlemm's canal could not be catheterized >180 degrees. Success was defined as final intraocular pressure ≤21 mm Hg, with (qualified success) or without (complete success) glaucoma medications. RESULTS In total, 74 eyes of 63 consecutive patients were included. MAT was performed in 50 eyes (67.6%). Postoperative intraocular pressure and number of glaucoma drops (17.7±8.6 mm Hg, 0.6±1.2 medications) was significantly less than the preoperative values (35.3±7.2 mm Hg, 2.7±0.8 medications; P<0.001). Cumulative probabilities of qualified and complete success were 84.0% and 80.0% at 3-year follow-up with no difference between complete and partial trabeculotomies. MAT was not successfully performed in 24 eyes (32.4%), requiring conversion to traditional trabeculotomy and associated with greater incidence of previous surgeries (P<0.001), earlier age of disease onset (P=0.024) and worse corneal transparency (P=0.010). Cumulative probabilities of qualified and complete success were 37.0% and 29.2% at 3-year follow-up. CONCLUSIONS Both complete and partial MAT achieved significant pressure reduction in cases of primary congenital glaucoma with previous failed glaucoma surgeries in intermediate term.
