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
PRCIS In children, Baerveldt implants showed 84% success at 1 year, but decreased to 32% at 8 years. Age, race, and glaucoma type were not risk factors for failure. Concurrent intraocular surgery was associated with complications. PURPOSE Evaluate success and risk factors for failure and complications of Baerveldt glaucoma implants in children. METHODS Retrospective case series of children who underwent Baerveldt implant placement (2012-2019 by single surgeon) with ≥1 year follow-up. Ocular examination and surgical details were collected. Failure defined as intraocular pressure (IOP) <5 mm Hg or >21 mm Hg for 2 consecutive visits, need for IOP related surgery, or visually significant complication. RESULTS One hundred-six eyes of 76 patients underwent 110 Baerveldt placement at median 6.4 years. Baerveldt placement was combined with additional procedures in 49% with vitrectomy most common (30%). Success of first Baerveldt (per patient) was 64% at final follow-up (median 4.7 y). One-, 5-, and 8-year survival rates were 84%, 60%, and 32%, respectively. There was no difference (P=0.97) in survival between first Baerveldt and all Baerveldt surgeries. Failure of first Baerveldt was not associated with sex, age, ethnicity, prior IOP-lowering surgery, concurrent intraocular surgery, or glaucoma type. Complications occurred in 14% and were associated with concurrent surgery. Twenty-six percent required additional IOP-lowering surgery. At final follow-up, IOP and glaucoma medications were significantly decreased (P<0.0001). Eyes underwent an average of 3.8±2.3 ocular surgeries and 3.0±2.0 glaucoma surgeries. CONCLUSIONS Baerveldt implants showed good success initially, but survival rates declined over time. No risk factors for failure of first implanted Baerveldt were identified. Concurrent surgery was associated with complications. Majority of eyes required multiple surgeries to achieve IOP control and preserve vision.

Abstract
PURPOSE To determine the visual outcomes and effectiveness of glaucoma surgeries in congenital ectropion uvea. DESIGN Retrospective interventional case series. METHODS Surgeries and examination findings were collected on 11 eyes of 8 patients with congenital ectropion uvea at 2 academic sites from 2001 to 2021. Visual outcomes, surgical success (intraocular pressure [IOP]: 5-20 mm Hg, no additional IOP-lowering surgery, no visually devastating complications), and survival rates of glaucoma surgeries were assessed. RESULTS Glaucoma in bilateral congenital ectropion uvea was diagnosed at an earlier age (0.02 ± 0.01 years) than unilateral disease (8.9 ± 5.3 years, P = .002). All eyes required glaucoma surgery with 91% requiring multiple surgeries (3.5 ± 2.1, median 3 surgeries per eye). Trabeculotomy (8 eyes) showed 13% success rate. Although none of the 4 eyes that underwent trabeculectomy with mitomycin C needed repeat trabeculectomy, glaucoma drainage device placement, or cycloablation, 75% required bleb revision surgery. Glaucoma drainage devices (7 eyes) had a 57% success rate with 3 eyes requiring subsequent cycloablation (2) or trabeculectomy (1). At the final follow-up (8.5 ± 6.6 years, median: 7.9 years), all eyes achieved IOP control, and IOP was lower compared with presentation (13.2 ± 2.6 mm Hg vs 32.9 ± 9.9 mm Hg, P = .002). Best-corrected logarithm of the minimum angle of resolution visual acuity at the final follow-up was 0.2 ± 0.2. CONCLUSIONS Bilateral congenital ectropion uvea presents with glaucoma earlier than unilateral cases. The majority of eyes required multiple glaucoma surgeries. Angle surgery was less effective than trabeculectomy or glaucoma drainage devices. IOP control was obtained in all eyes and affected individuals had good visual outcomes.

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.

Surgical Outcomes of Superotemporal Versus Inferonasal Placement of Aurolab Aqueous Drainage Implant in Refractory Pediatric Glaucoma. Am J Ophthalmol 2021; 224:102-111.

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
Glaucoma drainage device (GDD)-related endophthalmitis is a devastating complication of device implantation. There are no guidelines in the literature to assist clinicians in deciding if the GDD should be explanted or if patients require pars plana vitrectomy (PPV). This study compares the outcomes of GDD explantation with device retention and also independently compares the outcomes of PPV versus intravitreal antibiotics alone in patients with GDD-related endophthalmitis. A literature search for studies discussing GDD-related endophthalmitis from 2005 to 2019 was performed; 30 articles were included. The visual acuity/anatomical outcomes were compared between GDD explantation and retention, and between patients that received a PPV and those that did not. These outcomes were combined with a medical records review of 13 patients with GDD-related endophthalmitis from an academic institution. A total of 88 eyes were included. 70.5% underwent GDD explantation, while 37.8% received a PPV. GDD explantation was associated with a lower rate of evisceration/enucleation when compared to GDD retention (4.8% versus 19.2%, OR 0.22, 95% CI 0.05-1.01, p = 0.05), but visual acuity outcomes were similar. No eyes that received an immediate vitrectomy became phthisic or required evisceration/enucleation, compared an evisceration/enucleation rate of 15.2% in eyes treated solely with intravitreal antibiotics (OR 1.18, 95% CI 1.04-1.33, p = 0.04). Explantation of the GDD and immediate vitrectomy are both associated with better anatomical outcomes in GDD-related endophthalmitis. Further research is needed to provide more definitive guidelines in the ideal management of these patients.

Biomechanical Analysis of Ligatures and Technique for Managing Drainage Tubes in Pediatric Glaucoma. J Glaucoma 2020; 28:934-936.

Abstract
PURPOSE Absorbable ligatures are often used with glaucoma drainage tubes to avoid early postoperative hypotony. We sought to measure the force required to ligate a drainage tube, and develop a modified technique to promote earlier release in pediatric patients, where plate encapsulation occurs more quickly than adults. METHODS A precision digital force gauge was used to measure the tensile strength of several common ophthalmic sutures, and the necessary tensile force required to achieve tube ligation. A novel technique for tube ligation was devised to allow sutures as small as 10-0 to be effectively used. RESULTS The mean tensile strengths of unknotted sutures varied from 55.50±8.50 g for 10-0 vicryl to 477±69 g for 6-0 chromic gut. The mean tensile force required to ligate a Baerveldt or Ahmed tube was 35.9±0.9 g. However, 9-0 or 10-0 vicryl could not be reliably used for ligation, because of breakage, unless a modified technique was used, wherein the tube was first stretched to reduce its thickness and diameter. DISCUSSION Frictional forces inherent to knot tying make it unfeasible to reliably use 9-0 or 10-0 vicryl to ligate a drainage tube, despite the unknotted threads possessing apparently sufficient tensile strength. Our modified ligation technique overcomes this issue, allowing a wider range of suture choices, and the potential for achieving more rapid release in pediatric cases.

Abstract
PURPOSE OF REVIEW The management of pediatric glaucoma poses a unique challenge in terms of maintaining lifelong vision and combating an aggressive scarring response from surgery. Contemporary literature regarding the surgical management of children with pediatric glaucoma who fail, or are at a high risk of failure, from conventional surgery is limited. The aim of this review is to highlight recent developments in relation to the current opinion regarding the management of children with refractory pediatric glaucoma. RECENT FINDINGS Some studies have reported impressive success rates with circumferential trabeculotomy, even in eyes with previous failed surgery. Early results of deep sclerectomy in populations which may not respond well to conventional angle surgery are encouraging but data is limited for the pediatric age group. In compliant patients in whom multiple postoperative examinations under anesthesia are possible, trabeculectomy remains an effective procedure. Multiple recent studies have demonstrated that glaucoma drainage device (GDD) surgery is associated with 5-year success rates of over 70% in primary childhood glaucomas. SUMMARY Glaucoma drainage device surgery is likely to remain a mainstay of surgical management for refractory glaucoma in older children. More prospective data are needed on the success of circumferential trabeculotomy, deep sclerectomy and micropulse laser in pediatric eyes with previous failed surgery.

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.

Outcome of a Low-Cost Glaucoma Implant versus the Baerveldt Glaucoma Implant for Paediatric Glaucoma in a Tertiary Hospital in Egypt. J Ophthalmol 2019; 2019:5134190.

Abstract
Purpose To compare safety and efficacy between a low-cost glaucoma drainage device (GDD), the Aurolab aqueous drainage implant (AADI), and the Baerveldt glaucoma implant (BGI) in refractory childhood glaucoma in Egypt. Methods This is a retrospective study of patients who received either an AADI or BGI at a tertiary care postgraduate teaching institute. Children aged <16 years with uncontrolled intraocular pressure (IOP) with or without prior failed trabeculectomy who completed a minimum 6-month follow-up were included. The outcome measures were IOP reduction from preoperative values and postoperative complications. Results Charts of 57 children (younger than 16 years old) diagnosed with refractory childhood glaucoma were included. Of these, 27 eyes received AADI implants (group A), while 30 received BGI implants (group B). The mean preoperative baseline IOP was 34 ± 5 mmHg in group A versus 29 ± 2 mmHg in group B (p=0.78) in patients on maximum allowed glaucoma medications. In group A versus group B, the mean IOP decreased to 13.25 ± 8.74 mmHg (p=0.6), 12.8 ± 5.4 mmHg (p=0.7), and 12.6 ± 5.6 mmHg (p=0.9) after 1 week, 3 months, and 6 months, respectively. However, in group A, an anterior chamber reaction appeared around the tube in 14 cases starting from the first month and resolved with treatment in only 4 cases. In the other 10 cases, the reaction became more severe and required surgical intervention. This complication was not observed in any eye in group B. Conclusion AADI, a low-cost glaucoma implant, is effective in lowering IOP in patients with recalcitrant paediatric glaucoma. However, an intense inflammatory reaction with serious consequences developed in some of our patients; we believe these events are related to the valve material. We therefore strongly recommend against its use in children.

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
BACKGROUND In glaucoma therapy, there are many treatment options, such as glaucoma drainage devices (GDI). The aim of this study is to compare postoperative outcomes after using different surgical techniques. MATERIAL AND METHODS 269 eyes of 250 patients who received a GDI at the ophthalmological center at the university hospital in Cologne between February 2010 and September 2016 were included in this study. The patients' baseline parameters were collected: age, sex, intraocular pressure, visual acuity, glaucoma medication, diagnosis, operated eye (right or left), number of previous eye surgeries (including laser therapy), duration-of-stay at the hospital as well as all glaucoma complications and complication-related reoperations. RESULTS The mean individual pressure reduction was 39, 42 and 46% after 6, 12 and 24 months respectively, while the use of medication was reduced by 38, 42 and 50%. The success rates after 1 to 5 years was 75, 60, 57, 50 and 37% with a median survival of 48 months. 86 eyes (32%) experienced early complications and 156 eyes (56%) experienced late complications. 52% of the eyes (n = 139) had to be re-operated. The technique of creating a track to enter the anterior chamber had statistically significant influence on the early postoperative hypotony (p < 0,001). Fibrin glue had no influence on early hypotony. In the univariate analysis of early postoperative hypertension requiring paracentesis, the implant type (p = 0,009), tracking-technique with a paracentesis knife or a 22-gauge needle (p = 0,004), the occlusion method (p = 0,001) and the application of viscoelastics (p = 0,001) were statistically significant parameters. If GDI were implanted as a second implant, significantly more conjunctival erosion was recorded (p = 0.040). CONCLUSION The use of a 22-gauge needle entering the anterior chamber reduces the hypotony risk when compared to fibrin glue. That risk is not increased by adding venting slits. When implanting GDI as a second implant, the higher risk of conjunctival erosion should be considered.

Abstract
PURPOSE Congenital ectropion uvea is a rare anomaly, which is associated with open, but dysplastic iridocorneal angles that cause childhood glaucoma. Herein, we present 3 cases of angle-closure glaucoma in children with congenital ectropion uvea. OBSERVATIONS Three children were initially diagnosed with unilateral glaucoma secondary to congenital ectropion uvea at 7, 8 and 13 years of age. The three cases showed 360° of ectropion uvea and iris stromal atrophy in the affected eye. In one case, we have photographic documentation of progression to complete angle closure, which necessitated placement of a glaucoma drainage device 3 years after combined trabeculotomy and trabeculectomy. The 2 other cases, which presented as complete angle closure, also underwent glaucoma drainage device implantation. All three cases had early glaucoma drainage device encapsulation (within 4 months) and required additional surgery (cycloablation or trabeculectomy). CONCLUSIONS AND IMPORTANCE Congenital ectropion uvea can be associated with angle-closure glaucoma, and placement of glaucoma drainage devices in all 3 of our cases showed early failure due to plate encapsulation. Glaucoma in congenital ectropion uvea requires attention to angle configuration and often requires multiple surgeries to obtain intraocular pressure control.

Abstract
PURPOSE: To evaluate the outcomes of Ahmed glaucoma valve implantation in refractory primary congenital glaucoma as well as primary procedure in aphakic glaucoma. METHOD: In this retrospective study, medical records of patients who underwent Ahmed glaucoma valve implantation for refractory glaucoma and aphakic glaucoma were reviewed. Primary outcome measures were the surgical success defined as intraocular pressure ≤21 mm Hg and decreased ≥20% and no secondary glaucoma surgery. Secondary outcome measures were the number of glaucoma medications, complications, best corrected visual acuity, and intraocular pressure. RESULTS: A total of 62 eyes of refractory primary congenital glaucoma patients (group 1) and 33 eyes of aphakic glaucoma patients (group 2) were included in our study. Mean follow-up was 51 ± 33 months in group 1 and 49 ± 41 months in group 2 (p = 0.82). The cumulative probability of success was 90% in both groups at the first year; however, the success rate was 52.5% in group 1 and 71.5% in group 2 at 5 years' follow-up visit. In group 1, the mean intraocular pressure ± standard deviation was 33.1 ± 8.6 mm Hg at the baseline and decreased to 17.1 ± 5.3 mm Hg at 1 year and 18.5 ± 6.4 at 3 years postoperatively (all p's < 0.001). Corresponding values for group 2 were 28.9 ± 6.1, 15.2 ± 4.6, and 16.0 ± 5.9 mm Hg, respectively (all p's < 0.001). The baseline number of glaucoma medications was 3 ± 0.7 that decreased to 2 ± 0.8 at final follow-up (p = 0.02). CONCLUSION: Ahmed glaucoma valve implantation has a moderate success rate in the management of refractory primary congenital glaucoma with an increased chance of tube-related complications. The surgical success rate is higher in case of primary Ahmed glaucoma valve implant for aphakic glaucoma with acceptable safety profile.

Abstract
Purpose Retinal changes secondary to hypotony are usually described as wrinkling or folding of the inner portion of the choroid, the retinal pigment epithelium (RPE), and the outer retinal layers in the macular area due to scleral wall collapse. We describe a new retinal finding in children with suspected hypotony after implantation of Baerveldt Glaucoma Implant (BGI). Observations Four patients in our series developed significant RPE defects after BGI implant. The RPE defects appeared as elongated white lines observed solely in the posterior pole, in no particular pattern, and seemed to be worse in infants with anterior segment dysgenesis and with collagen disorders. Conclusion and importance Children have thinner and more elastic scleral walls than adults. This characteristic may cause the inward scleral wall to collapse when the eye is hypotonic. The resulting redundancy of the retina leads to wrinkling and RPE defects characterized by hypopigmented lines predominantly in the macular area. Such findings, to our knowledge, have not been previously reported in pediatric patients.

Abstract
PURPOSE To evaluate efficacy of combined vitrectomy with posteriorly placed glaucoma drainage device (GDD) in lowering intraocular pressure (IOP) in children. METHODS The medical records of children who underwent vitrectomy with posteriorly placed GDD were reviewed retrospectively. Patients with a minimum of 6 months' follow-up were included. The first eye operated on for each patient was analyzed. Success was defined as IOP of 5-20 mm Hg and no additional IOP-lowering surgery or visually devastating complications. RESULTS A total of 20 patients were included, with the following etiologies: primary infantile-onset glaucoma, 5 (25%); traumatic glaucoma, 3 (15%); Peters anomaly, 3 (15%); microphthalmia, 5 (25%); glaucoma following cataract surgery, 2 (10%); microspherophakia, 1 (5%); and retinopathy of prematurity, 1 (5%). Eyes with corneal opacification (8 [40%]) underwent endoscopic vitrectomy (5 [25%]), concurrent penetrating keratoplasty (3 [15%]) and/or keratoprosthesis surgery (1 [5%]). Mean follow-up was 1.9 ± 1.1 years (range, 6.5-49.2 months). Vision remained stable or improved in 17 eyes (85%). Mean IOP decreased from 27.2 ± 10.1 mm Hg to 14.5 ± 6.8 mm Hg (P < 0.0001) at last follow-up or at failure. Kaplan-Meier curves showed 12- and 24-month rate of IOP control of 69% and 62%, respectively. The number of glaucoma medications decreased from a mean of 2.3 ± 1.4 to 1.3 ± 1.2 (P < 0.015) at last follow-up or at failure. Overall success rate was 65%. Complications included hypotony (3 [15%]), vitreous hemorrhage (1 [5%]), and retinal detachment (1 [5%]). Two eyes (10%) required surgery for hypotony; 4 eyes (20%) underwent additional glaucoma surgery. CONCLUSIONS Combined surgical approach with vitrectomy and posteriorly placed GDD decreased IOP in complex pediatric glaucomas. Further, endoscope-assisted vitrectomy is useful in cases with corneal opacification. Complication rates of this combined procedure appear to be comparable to traditional anterior chamber approach.

Abstract
PURPOSE To compare the postoperative outcomes and complications of glaucoma drainage device (GDD) surgery in pediatric (<18 years old) and adult patients. METHODS Retrospective, comparative study including all patients who underwent Baervedlt or Molteno device surgery by the same surgeon. Success criteria included postoperative intraocular pressure (IOP) between 6 and 21 mmHg and a 20% reduction from baseline. RESULTS Fifty-two children (69 eyes) and 130 adults (145 eyes) were included. Mean IOP and number of medications were significantly reduced postoperatively in both groups. Overall failure rate was similar in children and adults. However, GDD failed earlier in adults than in children. Hypotony was the most common complication in both groups in the first 6 months postoperatively. Later on, bleb encapsulation was more frequent in children, while corneal decompensation tended to be more frequent and occurred earlier in adults. Children also had a higher rate of infectious endophthalmitis and required tube repositioning more frequently than adults. CONCLUSIONS GDD surgery presents different postoperative challenges in children and adults, and the surgeon should remain vigilant for complications throughout the postoperative period, especially for signs of endophthalmitis or bleb encapsulation in pediatric patients. On the other hand, adults may be more prone to early corneal decompensation.
