Abstract
Background To investigate the clinical features of corneal opacity and the surgical outcome of penetrating keratoplasty (PK) in eyes with congenital glaucoma. Methods A retrospective review was made of the records from 320 eyes of 193 patients who were diagnosed with congenital glaucoma between January 1981 and January 2016. Anterior segment photographs at disease presentation were examined for the presence and severity of corneal opacity. Data on patient demographics, intraocular pressure (IOP), ocular and systemic comorbidities, ocular surgery and its outcome were collected. Results Overall, corneal opacification was observed in 248 of 320 eyes (77.5%). Out of 248 eyes with corneal opacification, 53 eyes had Haab striae alone, and 195 eyes presented with either nebulomacular corneal opacity (128 eyes, iris details visible through opacity) or leukomatous corneal opacity (67 eyes, iris details invisible through opacity). In 12 eyes with severe leukomatous corneal opacity, PK was performed at the mean age of 18.6 months (range 4–57 months). The grafts failed in 6 eyes (50%) due to endothelial rejection (4 eyes) or graft infection (2 eyes) during the mean 80.6 months of follow-up (range 15–228 months). The median survival time was 36 months. The graft failure was significantly associated with smaller corneal diameter at the time of surgery, but not with the age, IOP, combined aniridia, simultaneous glaucoma or lens surgery. Conclusion Congenital glaucoma was combined with corneal opacity in 77.5%. The corneal transplant survival was 50% in eyes with congenital glaucoma and total corneal opacity.

Bayoumi NH. Mitomycin C in Filtering Surgery for Primary Congenital Glaucoma: A Comparison of Exposure Durations. J Pediatr Ophthalmol Strabismus 2018; 55:164-170.

Abstract
PURPOSE To compare the effect of two exposure durations of mitomycin C in combined angle and filtering surgery for primary congenital glaucoma. METHODS This was a prospective study conducted in the Department of Ophthalmology at Alexandria Main University Hospital, Alexandria, Egypt, on 75 eyes with primary congenital glaucoma that underwent combined trabeculotomy-trabeculectomy with intraoperative mitomycin C application for 1 minute (MMC 1) or 2 minutes (MMC 2) and were followed up for 24 months. Success rates were studied and complications noted. Success was defined by a composite primary end point of an intraocular pressure (IOP) of less than 16 mm Hg under general anesthesia, without any IOP-lowering medications and with no hypotony-related complications and/or lack of IOP-related progression of the disease as evidenced by worsening of the ocular biometric characteristics. RESULTS The mean age of the study participants was 6.7 ± 4.1 months (range: 2 to 16 months; median: 6 months) in the MMC 1 group (35 eyes) and 7.7 ± 5.7 months (range: 1 to 32 months; median: 6.5 months) in the MMC 2 group (40 eyes). The initial surgery was successful in 32 (91.5%) and 31 (77.5%) eyes in the MMC 1 and MMC 2 groups, respectively. The mean IOP was 18.4 ± 5.1 and 18.1 ± 6.1 mm Hg preoperatively and 5.5 ± 3.5 and 4.8 ± 2.8 mm Hg at the end of follow-up in the MMC 1 and MMC 2 groups, respectively. There was no statistically significant difference in the clinical parameters between the two groups. Complications included cataracts in each group and hypotony optic disc edema in 3 eyes (7.5%) in the MMC 2 group. CONCLUSIONS Both mitomycin C application durations were effective in combined trabeculotomy-trabeculectomy with mitomycin C for primary congenital glaucoma. The longer duration was not advantageous in disease control and there were no significant differences in complications. [J Pediatr Ophthalmol Strabismus. 2018;55(3):164-170.].

Abstract
Primary congenital glaucoma is a trabecular meshwork dysgenesis with resultant increased intraocular pressure and ocular damage. CYP1B1 mutations remain the most common identifiable genetic cause. However, important questions about the penetrance of CYP1B1-related congenital glaucoma remain unanswered. Furthermore, mutations in other genes have been described although their exact contribution and potential genetic interaction, if any, with CYP1B1 mutations are not fully explored. In this study, we employed modern genomic approaches to re-examine CYP1B1-related congenital glaucoma. A cohort of 193 patients (136 families) diagnosed with congenital glaucoma. We identified biallelic CYP1B1 mutations in 80.8% (87.5 and 66.1% in familial and sporadic cases, respectively, p < 0.0086). The large family size of the study population allowed us to systematically examine penetrance of all identified alleles. With the exception of c.1103G>A (p.R368H), previously reported pathogenic mutations were highly penetrant (91.2%). We conclude from the very low penetrance and genetic epidemiological analyses that c.1103G>A (p.R368H) is unlikely to be a disease-causing recessive mutation in congenital glaucoma as previously reported. All cases that lacked biallelic CYP1B1 mutations underwent whole exome sequencing. No mutations in LTBP2, MYOC or TEK were encountered. On the other hand, mutations were identified in genes linked to other ophthalmic phenotypes, some inclusive of glaucoma, highlighting conditions that might phenotypically overlap with primary congenital glaucoma (SLC4A4, SLC4A11, CPAMD8, and KERA). We also encountered candidate causal variants in genes not previously linked to human diseases: BCO2, TULP2, and DGKQ. Our results both expand and refine the genetic spectrum of congenital glaucoma with important clinical implications.

Abstract
PURPOSE To correlate the features of certain types of infantile glaucoma with the progression and the prognosis of the disease, highlighting probable risk factors. METHODS Seventy-six patients with pediatric glaucoma were recruited in this retrospective study. All patients underwent ophthalmological examination in the Department of Ophthalmology of the Saarland University Medical Center from January 2001 to December 2012. Our pediatric patients were classified into four different categories of glaucoma: (1) primary congenital glaucoma (presenting buphthalmus), (2) aniridia-related glaucoma, (3) Peters/Rieger's anomaly-related glaucoma and (4) congenital cataract-related glaucoma. Personal data comprised age, sex, nationality, systemic diseases and gestational age. The best-corrected visual acuity (BCVA), the cup-disk ratio (CDR), the intraocular pressure (IOP), the corneal diameter and thickness, along with the Haab striae and corneal haze, were recorded. RESULTS The majority of the children were male (58%) and suffered from aniridia-related glaucoma (38%). Children with aniridia exhibited the worst BCVA. The CDR and IOP were significantly higher in children with primary congenital glaucoma, compared to the other groups, at the first visit. Those children also were with the largest corneal diameter and prevalence of Haab striae compared to the rest groups, whereas corneal haze was found more often and was more pronounced in children with Peters/Rieger's syndrome. CONCLUSIONS We concluded that glaucoma was earlier detected in children with primary congenital glaucoma, who exhibited increased corneal diameter and high percentage of Haab striae comparing to the other groups. However, these children responded successfully to any therapeutic intervention, exhibiting better BCVA and IOP values than the rest groups at the second visit.

Abstract
PURPOSE To date, there are limited data on the economic burden of childhood glaucoma, a relatively rare but visually debilitating disease. The purpose of this study is to evaluate the immediate costs of illness associated with childhood glaucoma during the first 4 years after presentation. METHODS Data on age, sex, surgical interventions, visits, examinations under anesthesia, and medications were collected yearly following presentation in patients with childhood glaucoma. Inclusion criteria included diagnosis of primary or secondary childhood glaucoma, age less than 21 years, and follow-up of 4 years. A total of 23 patients (39 eyes) were included. Cost analysis used 2013 hospital-specific charges and US average hourly wage to calculate outcomes of total, direct, and indirect costs (significance level P<0.05). RESULTS The annual cost of care of childhood glaucoma averaged $21,441.61 per patient, representing 1100% of annual costs in adult glaucoma and an increase of 800% in annual costs of health care per pediatric patient. The average total 4-year cost of care was $85,074.96 per patient. Surgical interventions and examinations under anesthesia were the greatest contributors to costs, representing 69.0% and 23.2% of total 4-year costs, respectively. The annual costs of care for childhood glaucoma were highest in the first year compared with subsequent years, averaging $46,293.62 per patient (P<0.05). CONCLUSIONS Childhood glaucoma carries a substantial economic burden with the highest costs occurring in the first year after presentation. The greatest contributors to cost of illness are surgical interventions and examinations and anesthesia.

Abstract
PURPOSE To compare releasable and regular sutures in combined angle and filtering surgery for primary congenital glaucoma. METHODS A prospective study was conducted on 39 eyes (26 right eyes) of 39 children (20 boys; 19 girls) who had primary congenital glaucoma treated with combined trabeculotomy-trabeculectomy with mitomycin C and scleral flap closure with regular or releasable sutures. Follow-up was 24 months. Success rates (defined as an intraocular pressure [IOP] < 16 mm Hg without hypotony-related complications and/or lack of IOP-related progression of the disease) were studied and complications were noted. RESULTS The mean age of the study participants was 6.7 ± 5.8 months (range: 1 to 24 months; median: 5 months) in the regular suture group (20 eyes) and 5.3 ± 2.8 months (range: 1 to 13 months; median: 5 months) in the releasable suture group (19 eyes). The initial glaucoma surgery was successful in 13 (65%) and 13 (68.4%) eyes in the regular suture and releasable suture groups, respectively. The mean IOP was 17.4 ± 7.3 and 16.0 ± 5.4 mm Hg (P = .84) preoperatively and 8.0 ± 9.7 and 5.8 ± 3.6 mm Hg (P = .40) at the end of follow-up in the regular suture and releasable suture groups, respectively. There was no statistically significant difference in the clinical parameters between the two groups. Complications included rhegmatogenous retinal detachment, cataract, and superior lens subluxation, with each complication developing in one eye. CONCLUSIONS Releasable sutures were not more advantageous than regular sutures in combined trabeculotomy-trabeculectomy with mitomycin C surgery for primary congenital glaucoma.

Abstract
Glaucoma is the leading cause of irreversible blindness worldwide. Although most glaucoma patients are elderly, congenital glaucoma and glaucomas of childhood are also important causes of visual disability. Primary congenital glaucoma (PCG) is isolated, non-syndromic glaucoma that occurs in the first three years of life and is a major cause of childhood blindness. Other early-onset glaucomas may arise secondary to developmental abnormalities, such as glaucomas that occur with aniridia or as part of Axenfeld-Rieger syndrome. Congenital and childhood glaucomas have strong genetic bases and disease-causing mutations have been discovered in several genes. Mutations in three genes (CYP1B1, LTBP2, TEK) have been reported in PCG patients. Axenfeld-Rieger syndrome is caused by mutations in PITX2 or FOXC1 and aniridia is caused by PAX6 mutations. This review discusses the roles of these genes in primary congenital glaucoma and glaucomas of childhood.

Abstract
PURPOSE To compare 1-year outcomes of illuminated microcatheter-assisted circumferential trabeculotomy (IMCT) vs conventional partial trabeculotomy (CPT) for primary congenital glaucoma (PCG). DESIGN Randomized clinical trial. METHODS Forty eyes of 31 patients with unilateral or bilateral primary congenital glaucoma aged less than 2 years were randomized to undergo IMCT (20 eyes) or CPT (20 eyes). Primary outcome measure was intraocular pressure (IOP) reduction. The success criterion was defined as IOP ≤ 12 mm Hg without and with antiglaucoma medications (absolute success and qualified success, respectively). RESULTS The mean age of our study population was 8.35 ± 1.2 months. The mean preoperative IOP was 24.70 ± 3.90 mm Hg in the IMCT group and 24.60 ± 3.31 mm Hg in the CPT group. Both groups were comparable with respect to preoperative IOP, corneal clarity, corneal diameter, vertical cup-to-disc ratio, and refractive error. In the IMCT group, 360-degree cannulation was achieved in 80% (16/20) of eyes. For the IMCT group and CPT groups, respectively, the absolute success rates were 80% (16/20) and 60% (12/20) (P < .001) and qualified success rates were 90% (18/20) and 70% (14/20) (P < .001). Both procedures produced a statistically significant reduction in IOP, and eyes undergoing IMCT achieved a lower IOP than CPT group eyes at 12 months follow-up (9.5 ± 2.4 mm Hg and 11.7 ± 2.1 mm Hg, respectively, P < .001). CONCLUSION In primary congential glaucoma, illuminated microcatheter-assisted 360-degree circumferential trabeculotomy performed better than conventional partial trabeculotomy at 1 year follow-up and resulted in significantly lower IOP measurements.

Abstract
OBJECTIVE To estimate long term future of pressure and vision of children who underwent DS for CPG. MATERIAL AND METHODS Children affected by CPG, aged from 1 day to 3 years at the time of the diagnosis were retrospectively included between 1999 and 2014. All benefited from a DS with use of antimetabolites. Preoperative and long-term post-operative intraocular pressures (IOP), per and postoperative complications as well as visual acuity and refractive status were estimated. Complete IOP control was defined by a postoperative IOP ≤16 mmHg without medical treatment. RESULTS 141 eyes of 71 children were included (sex ratio: 1.02). Mean follow-up was 56.6 ±9.6 months. Final average IOP among the whole sample was 11.3 +/-7 mmHg. The rate of total success was 69.4 %, partial success 27.6 % and 3 % failure at the last check. No complications were seen in 85.1 % of cases (n=120 eyes). Among 37 children analyzed for visual acuity, maintained visual acuity was found in 50 % of cases (n= 37 eyes). CONCLUSION DS allows obtaining good IOP control with a very low rate of complications, and should be considered as a technique of choice in the surgical management of CPG. This study is of particular relevance because it has been led on a long term period and on an important staff considering the rare prevalence of the condition.

Abstract
Aim This is a report of the incidence of bilateral cases in a cohort of primary congenital glaucoma (PCG) cases and a study of the biometric characteristics of the fellow normal eyes in unilateral cases. Materials and methods The charts of 134 PCG children were reviewed, of which 78 cases (58.2%) were found to have bilateral disease. The remaining 56 patients (41.8%) with unilateral disease had their fellow normal eyes compared with an age-matched cohort of ophthalmologically free children. Results There were no differences between the normal fellow eyes of PCG cases and the control eyes in the corneal diameter and central corneal thickness (CCT), whereas the normal fellow eyes of PCG cases had higher intraocular pressure (IOP) and cup/disc (C/D) ratios. Conclusion The fellow eyes of apparently unilateral PCG cases are not typically normal anatomically like other children unaffected by PCG. Clinical significance A very high index of suspicion has to be kept for PCG cases that present apparently unilaterally, and meticulous prolonged follow-up is mandatory.

Abstract
Purpose: To evaluate the Childhood Glaucoma Research Network (CGRN) classification system and describe the prevalence of each subtype according to this classification. Materials and Methods: Retrospectively, the medical records of 205 consecutive childhood glaucoma and glaucoma suspect patients at an urban tertiary care center were reviewed. The initial diagnosis and new diagnosis according to CGRN classification were recorded. Results: All patients fit one of the seven categories of the new classification. Seventy-one percent of diagnoses were changed upon reclassification. Twenty-three percent of patients had primary glaucoma (juvenile open-angle glaucoma and primary congenital glaucoma [PCG]); 36% had secondary glaucoma (glaucoma associated with nonacquired ocular anomalies; glaucoma associated with nonacquired systemic disease or syndrome; glaucoma associated with acquired condition; and glaucoma following cataract surgery); and 39% were glaucoma suspect. Of the patients diagnosed with glaucoma, PCG was the most common diagnosis, seen in 32% of patients. Conclusion: The CGRN classification provides a useful method of classifying childhood glaucoma.

Abstract
PURPOSE To perform a longitudinal analysis on the association of corneal haze with intraocular pressure (IOP) in eyes with primary congenital glaucoma (PCG) over 3 years. PATIENTS AND METHODS Charts of all patients diagnosed with glaucoma of childhood from 2002 to 2012 at our institution were retrospectively reviewed. Inclusion criteria were age 18 years and below, plus elevated IOP or characteristic clinical signs. Exclusion criteria were eyes with secondary glaucoma or corneal haze not from PCG and patients with prior ocular surgery or incomplete follow-up. RESULTS Of 79 eyes with childhood glaucoma during this period, 36 eyes had PCG [25 patients; 15 male (60.0%), 14 bilateral (56.0%)]. Eighteen eyes (13 patients) presented with corneal haze, whereas 18 eyes (12 patients) did not. Eyes with haze were diagnosed at a younger age than eyes without haze (0.79 vs. 5.2 y, P<0.02). During year 1, eyes with haze underwent significantly more IOP-lowering procedures and used significantly fewer IOP-lowering medications. Multivariate analysis revealed that corneal haze increased IOP by 4.63 mm Hg when controlling for treatment over time (P<0.01). Eyes with haze had lower survival curves and a failure hazard of 1.3 times that of eyes without haze. These eyes had a lower proportion of qualified successes than eyes without haze at year 1 (P<0.05) but this was reversed at year 3 (P<0.02). CONCLUSIONS Eyes with PCG-related corneal haze generally presented more severely than did those without haze, but postmanagement outcomes may be similar to those in eyes without haze.

Abstract
PURPOSE To report and compare visual and glaucoma outcomes in primary congenital glaucoma (PCG) vs glaucoma following congenital cataract surgery (GFCS). DESIGN Retrospective, observational, comparative case series. METHODS Setting: Emory Eye Center, Atlanta, Georgia. STUDY POPULATION Pediatric glaucoma patients (age 0-18 years) treated at Emory by 1 clinician with ≥2-year follow-up. Glaucoma was defined according to the 9th Consensus Report of the World Glaucoma Association. MAIN OUTCOME MEASURES Snellen-equivalent logMAR visual acuity (VA) and glaucoma control (IOP ≤21, no devastating complications, no recommendation for further glaucoma surgery). Asymptotic Wilcoxon-Mann-Whitney rank sum tests were employed to compare glaucoma subgroups. RESULTS Included were 72 PCG and 56 GFCS cases, with mean follow-up time of 7.4 ± 4.1 and 8.0 ± 3.8 years, respectively. At last follow-up, PCG showed better median VA than GFCS in worse-seeing eyes (20/60 [interquartile range (IQR) 20/30-20/200] vs 20/400 [IQR 20/70-hand motion], respectively, P < .0001) and in better-seeing eyes of bilaterally-affected children (20/30 [IQR 20/20-20/60] vs 20/70 [IQR 20/35-20/100], respectively, P = .024).The following variables characterized the PCG and GFCS groups' glaucoma status, respectively: mean age at diagnosis (years), 0.70 ± 1.3 vs 3.3 ± 3.5 (P < .0001); median IOP (mm Hg), 15.50 [IQR 12.1-19.4] vs 17.50 [IQR 14.9-22], P = .037; median number of glaucoma medications at last follow-up, 1.49 [IQR 0-2] vs 2.54 [IQR 1-4], P < .0001; median number of glaucoma surgeries, 1.0 [IQR 1-2] vs 1.25 [IQR 0.5-2.0], P = .09. CONCLUSIONS Children with PCG (vs those with GFCS) presented earlier, had better vision, required fewer medications to control disease, and had lower IOP at last follow-up.

Abstract
Introduction To investigate the efficacy of a treatment strategy with latanoprost and dorzolamide in primary pediatric glaucoma patients partially responsive to surgery. Methods Single arm, prospective, interventional multicenter study. Primary pediatric glaucoma patients younger than 13 years after a single surgical procedure with IOP between 22 and 26 mmHg were considered eligible. At baseline, patients were allocated to latanoprost monotherapy once daily. Depending on intraocular pressure (IOP) reduction at first visit, the patients were allocated to one of three groups: continuation of latanoprost monotherapy, addition of dorzolamide twice daily, or switch to dorzolamide three times daily. The same approach for allocation in medication groups was used in all subsequent visits. Patients in the dorzolamide monotherapy group with IOP reduction <20% from baseline were considered non-responders and withdrawn. Study treatment and patient follow-up will continue for 3 years or until treatment failure. The primary endpoint is the percentage of responders. Secondary endpoints are time to treatment failure and frequency of adverse events. Results A total of 37 patients (69 eyes) were enrolled. The mean age was 4.0 ± 3.8 years, the female/male ratio was 1/1.7, and the majority of patients were Caucasian. Eighty percent of patients had bilateral glaucoma. Goniotomy was the most frequently performed surgery (38.6%), followed by trabeculotomy (22.8%), trabeculectomy (21.1%), and trabeculectomy plus trabeculotomy (17.5%). The baseline IOP was 23.6 ± 1.5 mmHg. Conclusion The study population is representative of patients frequently encountered after the first surgery for primary pediatric glaucoma. The study will produce evidence on the medium-term efficacy of a defined pharmacological approach.

Abstract
Childhood glaucoma is a major therapeutic challenge for pediatric ophthalmologists and glaucoma specialists worldwide. Management depends on the etiology and age at presentation. A variety of drugs are available for the control of intraocular pressure in children; however, none of these drugs have been licensed by the regulatory agencies for use in children. Furthermore, evidence gained from randomized controlled trials in the pediatric population is sparse, and little is known regarding the use of newer anti-glaucoma preparations. This evidence-based review aims to discuss the available pharmacotherapeutic options for glaucoma in children. Topical adrenoceptor blockers, topical and systemic carbonic anhydrase inhibitors, prostaglandin (PG) analogs, adrenoceptor agonists, parasympathomimetics, and combined preparations are available for use in children, but usually as an off-label indication. Therefore, it is important to recognize that serious side effects have been reported, even with topical drops, and measures to reduce systemic absorption should be taken. Most drugs have been shown to have comparable ocular hypotensive effects, with the lowest occurrence of systemic side effects with PG analogs. Whereas a newly introduced prostaglandin analog, tafluprost, and some other preservative-free preparations have shown promising results in adult glaucoma patients, no pediatric reports are available as yet. Future studies may describe their role in treating pediatric glaucoma. This review also shares some suggested treatment pathways for primary congenital glaucoma (PCG), juvenile open angle glaucoma (JOAG), developmental glaucoma, aphakic/pseudophakic glaucoma, and uveitic glaucoma.

Abstract
AIM To evaluate goniotomy, trabeculotomy, transscleral cyclophotocoagulation (TSCPC) and trabeculectomy as initial procedures in children with primary childhood glaucoma from Northern Tanzania. METHODS A retrospective analysis of consecutive interventions for primary childhood glaucoma from 2000 to 2013 was conducted at the Kilimanjaro Christian Medical Centre. Success was defined as postoperative intraocular pressure (IOP) below 22 mmHg. Success rates, IOP, visual acuity (VA), subsequent interventions and potential risk factors for failure were reported for the respective interventions. RESULTS The study included 116 eyes of 70 children (age 4.6±5.9 years) with primary childhood glaucoma; 46 (65.7%) children were male. The preoperative IOP was 33.1±10.2 mmHg, the preoperative cup/disc (CD) ratio 0.71±0.3 and the corneal diameter 13.3±1.4 mm. As a primary intervention, 61 (52.6%) eyes underwent goniotomy, 10 (8.6%) eyes trabeculotomy, 12 (10.3%) TSCPC and 33 (28.4%) trabeculectomy. Follow-up data after 12 months were available for 63 (54.3%) eyes. Success rates at 12 months were 38% (goniotomy), 30% (trabeculotomy), 17% (TSCPC) and 64% (trabeculectomy). All interventions achieved a statistically significant IOP reduction at 3, 6 and 12 months, except for trabeculotomy after 6 months and TSCPC at all time points. Postoperative endophthalmitis occurred in one child treated with trabeculectomy. VA in 82% of all eyes was maintained or had improved after 12 months. CONCLUSIONS Based on the success rates of this retrospective analysis, goniotomy or trabeculotomy for younger and trabeculectomy for older children can be recommended in our setting to reduce IOP. Late presentation in combination with advanced glaucomatous damage as well as erratic postoperative follow-up and treatment were likely factors that compromised overall success rates. More efforts are necessary to detect the blinding disease earlier and improve adherence to follow-up.

Abstract
PURPOSE To describe demographic criteria of primary congenital glaucoma (PCG) subjects and to evaluate the surgical outcomes of children who underwent angle surgery over a 20-year period. METHODS This is a retrospective study of patients diagnosed with PCG who underwent trabeculotomy, trabeculectomy, or combined trabeculotomy-trabeculectomy (CTT). The surgery was considered to be successful if intraocular pressure (IOP) was 21 mm Hg or less with or without treatment. RESULTS A total of 148 eyes (85 patients) were included in the study. The majority of the patients were younger than 6 months of age (78.9%), with a median age of 2 months. Sex distribution was relatively even between girls and boys (45:40) (53%/47%). Bilateral disease was seen in 63 patients (74%). The overall success rate was achieved in 80.4%. The majority of the eyes needed only one surgery (105 [70.9%]), 34 eyes (23.0%) needed 2 surgeries, and 7 eyes (4.7%) had 3 surgeries. There was no statistically significant difference in success rate between types of surgery and number of performed procedures. A progressive decline in success rate over time was evident, as success rate dropped from 96.6% at 5 months to less than 50% after 11 years of follow-up. CONCLUSIONS Excellent IOP control can be achieved in a majority of patients with equally effective results from all 3 surgical procedures. The surgical outcome of PCG was more favorable in infants presenting before the age of 6 months. Adjuvant topical antiglaucoma medications can augment the surgical success rate.

Abstract
Introduction Primary congenital glaucoma (PCG) is the most common type of glaucoma in pediatric patients. The aim of this study was to compare the effectiveness of combined trabeculotomy-trabeculectomy versus Ahmed valve implantation for cases of PCG refractory to traditional incisional angle surgery (goniotomy and trabeculotomy) in the Egyptian population. Methods The study was conducted in the Glaucoma Clinic of the Research Institute of Ophthalmology (Egypt). The study included 66 eyes of 66 patients (in two groups) with advanced PCG who had previous failed goniotomy, trabeculotomy, or both. Group 1 included 33 patients who underwent trabeculotomy-trabeculectomy procedures; group 2 included 33 patients who underwent FP 8 Ahmed valve implantation. The main outcome measures were intraocular pressure (IOP) reduction, corneal diameter, and axial length stability in both groups. Secondary outcome measures included detection of complications in both groups. Results The average ages of the patients were 13.5 ± 3.9 months and 15.3 ± 5.8 months in groups 1 and 2, respectively. Ten patients (30.3%) in group 1 and 9 patients (27.3%) in group 2 had family histories of PCG. Positive consanguinity was present in 26 patients (78.8%) in group 1 and in 27 patients (81.8%) in group 2. In group 1, the mean intraocular pressure (IOP) value decreased from 33.6 ± 3.4 mmHg preoperatively to 13.8 ± 0.6, 16.9 ± 1.5, 18.2 ± 2.5, 19.8 ± 3.6, and 20.2 ± 3.1 mmHg in the first postoperative month and after years 1, 2, 3, and 4, respectively (p < 0.001). In group 2, the mean IOP value decreased from 33.4 ± 4.5 mmHg preoperatively to 13.3 ± 1.1, 16.3 ± 1.6, 18.1 ± 1.0, 19.1 ± 3.5, and 19.9 ± 3.7 mmHg in the first postoperative month and after years 1, 2, 3, and 4, respectively (p < 0.001). The average number of medications decreased from 2.2 ± 0.4 preoperatively to 1.8 ± 0.4 postoperatively in group 1, while it decreased from 2.1 ± 0.4 preoperatively to 1.9 ± 0.3 postoperatively in group 2. The success rate in group 1 was 97, 91, 76, and 61% in years 1, 2, 3, and 4, respectively, whereas the success rate in group 2 was 97, 93, 81, and 66% in years 1, 2, 3, and 4, respectively. Conclusion Both procedures, i.e., combined trabeculotomy-trabeculectomy and Ahmed valve implantation are suitable options in advanced PCG with failed trabeculotomy and goniotomy. Ahmed valve implanation has a better long-term survival, but trabeculotomy-trabeculectomy provides a second chance for surgical intervention.

Abstract
INTRODUCTION Primary congenital glaucoma (PCG) is a rare and sight threatening condition. Few large epidemiological studies are available in the literature concerning this condition. The purpose of the study was to evaluate the epidemiological and clinical characteristics of children affected by PCG. PATIENTS AND METHOD Children affected by PCG, from 1 day to 3 years old at the time of diagnosis were retrospectively included between 1999 and 2014. The analysis concerned the pregnancy, family history, initial referral, clinical presentation with description of the classic findings in this condition, mean age at first consultation, duration of follow-up and presence of a delay in treatment, defined as a delay of over one month from the appearance of clinical signs until diagnosis. Two groups were defined according to age at appearance of the clinical signs: "early" group prior to 2 months old and "late" group beyond 2 months up until 3 years old. RESULTS One hundred and forty-one eyes of 71 children were included, with 49.3% girls (n=35 children) and 50.7% boys (n=36 children) for a male:female ratio of 1.02. The "early" group included 50 children i.e. 70.3% of the population; the "late" group 21 children or 29.7% of the population. A first-degree family history of congenital glaucoma existed in 28% of cases (n=19). The average age at first consultation was 13.1 months for the entire population, and the mean duration of follow-up was 56.6 months. Involvement was bilateral in 99.3% of cases (n=70 children) and the most frequent clinical sign was buphthalmos in 64.5% of eyes (n=91 eyes). Treatment was delayed in 35.3% of cases (n=25 children). DISCUSSION AND CONCLUSION This study is of particular relevance because it was performed over a long period and on a large population, considering the rare prevalence of the pathology, and has found epidemiological and clinical data comparable with those available in the literature for similar populations.

Abstract
Context: Congenital glaucoma is a potentially blinding ocular disease of the childhood. Identification of the possible associated risk factors and may be helpful for prevention or early detection of this public health problem. Aims: To demonstrate the demographic features of congenital glaucoma subjects. Setting and Design: The charts of congenital glaucoma patients referred to Tamcelik Glaucoma Center were retrospectively reviewed through the dates of 2000 and 2013. Materials and Methods: Analyzed data included diagnosis, age at first presentation, symptoms at first presentation, laterality of the disease, sex, presence of consanguinity, family history of congenital glaucoma, maturity of the fetus at delivery, and maternal age at conception. Statistical Analysis Used: Statistical Package for Social Sciences (SPSS) version 19.0 by IBM (SPSS Inc, Chicago, Illinois, USA) was used to compare the mean of continuous variables with Student's t-test and analysis of variance (ANOVA) and χ2 test was used to test differences in proportions of categorical variables. Results: The data of 600 eyes of 311 patients were analyzed. The distribution of primary and secondary congenital glaucoma among the patients were 63.3% (n = 197) and 36.7% (n = 114), respectively. Of the 311 patients, 57.2% (n = 178) were male and 42.8% (n = 133) were female. The overall frequency of bilateral disease was 92.3% (n = 287). Overall rate of consanguinity and positive family history was 45.3% (n = 141) and 21.2% (n = 66), respectively. Conclusions: Bilateral disease in this study was more common than previously reported studies. Positive family history was more frequent in primary congenital glaucoma although not statistically significant.

Abstract
Noteworthy heterogeneity exists in the rare diseases associated with childhood glaucoma. Primary congenital glaucoma is mostly sporadic; however, 10% to 40% of cases are familial. CYP1B1 gene mutations seem to account for 87% of familial cases and 27% of sporadic cases. Childhood glaucoma is classified in primary and secondary congenital glaucoma, further divided as glaucoma arising in dysgenesis associated with neural crest anomalies, phakomatoses, metabolic disorders, mitotic diseases, congenital disorders, and acquired conditions. Neural crest alterations lead to the wide spectrum of iridocorneal trabeculodysgenesis. Systemic diseases associated with childhood glaucoma include the heterogenous group of phakomatoses where glaucoma is frequently encountered in the Sturge-Weber syndrome and its variants, in phakomatosis pigmentovascularis associated with oculodermal melanocytosis, and more rarely in neurofibromatosis type 1. Childhood glaucoma is also described in systemic disorders of mitotic and metabolic activity. Acquired secondary glaucoma has been associated with uveitis, trauma, drugs, and neoplastic diseases. A database research revealed reports of childhood glaucoma in rare diseases, which do not include glaucoma in their manifestation. These are otopalatodigital syndrome, complete androgen insensitivity, pseudotrisomy 13, Brachmann-de Lange syndrome, acrofrontofacionasal dysostosis, caudal regression syndrome, and Wolf-Hirschhorn syndrome.

Abstract
PURPOSE To describe a paediatric cohort surgically treated for primary or secondary glaucoma (PG/SG), with regard to incidences, visual outcome and control of intraocular pressure (IOP). METHODS All children (n = 29, 42 eyes in total) surgically treated for PG or SG at the age of 4 years or younger between January 2002 and December 2010 at Sahlgrenska University Hospital in Mölndal were retrospectively studied through medical records. Median follow-up time after initial surgery was 5.9 years (range 2.4-11.2 years). RESULTS The incidence of primary congenital glaucoma was 4.3 cases per 100 000 live births in the county of Västra Götaland. For glaucoma secondary to cataract surgery, the incidence was 13% with a median postoperative duration to diagnosis of glaucoma of 3.8 months (range 1.6 months to 4.3 years). Preoperative mean IOP was 31.5 (SD 8.1) mmHg, and mean IOP at last visit was 17.1 (SD 4.4) mmHg. For the entire cohort, 30% of the glaucoma eyes required more than two IOP-lowering surgical procedures during the study period. BCVA was ≥0.3 (decimal) in 45% of glaucomatous eyes at last follow-up with no statistically significant difference between PG and SG. Analysis of functional visual outcome, that is BCVA in the better eye, showed that 83% of all patients attained a BCVA of ≥0.5. CONCLUSIONS The incidences and outcome of surgically treated paediatric glaucoma were in accordance with previous studies. Chamber angle surgery, and if necessary, tube implantation without the use of antimetabolites, is a favourable approach leaving most sites needed for future glaucoma surgery unaffected.

Abstract
PURPOSE To determine in primary congenital glaucoma whether age of presentation influences surgical success, the degrees of angle surgery needed to achieve glaucoma control, and whether there are critical ages where glaucoma progresses, requiring further surgical management. DESIGN Retrospective cohort study. METHODS The medical records of patients with primary congenital glaucoma over a 23-year period were reviewed: 192 procedures were performed on 117 eyes (70 patients). The number and age of angle procedures and final visual acuity was analyzed. Surgical success was defined as stable intraocular pressure and optic disc appearance. RESULTS Procedures involving 83 of the 110 eyes (75.5%) undergoing angle surgery were successful, with 2-, 4-, 6-, and 10-year success rates of 92%, 86%, 84%, and 75%, respectively. Subgroup analysis (<3 months; 3-6 months; >6 months) comparing age of diagnosis to visual outcome (<20/200, 20/200-20/40, >20/40) was significant (P = .04). The age at first operation (P = .94), the number of angle operations (P = .43), and their effect on angle surgery success was not significant. Seven of 192 operations were performed after the age of 8 years (3.6%). After the initial angle surgeries within the first year of life, the third procedure occurred at a median age of 2.4 years (interquartile ratio [IQR] 0.6-3.8 years) and the fourth procedure occurred at a median age of 5.3 years (IQR 2.5-6.1 years). CONCLUSIONS Children diagnosed at <3 months of age had a visual outcome of <20/200 despite successful glaucoma control. Age of presentation did not affect surgical success. A total of 78.9% of cases undergoing primary trabeculotomy were controlled with 1 operation: 4 clock hours of angle (120 degrees). Analysis of glaucoma progression suggests critical ages where further glaucoma surgery is required at around 2 and 5 years of age.

Abstract
BACKGROUND Primary congenital glaucoma (PCG) manifests within the first few years of a child's life and is not associated with any other systemic or ocular abnormalities. PCG results in considerable morbidity even in developed countries. Several surgical techniques for treating this condition, and lowering the intraocular pressure (IOP) associated with it, have been described. OBJECTIVES To compare the effectiveness and safety of different surgical techniques for PCG. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2014, Issue 6), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to June 2014), EMBASE (January 1980 to June 2014), (January 1982 to June 2014), PubMed (January 1946 to June 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 23 June 2014. SELECTION CRITERIA We included all randomized and quasi-randomized trials in which different types of surgical interventions were compared in children under five years of age with PCG. DATA COLLECTION AND ANALYSIS We used standard methodological procedures specified by The Cochrane Collaboration. MAIN RESULTS We included a total of six trials (four randomized and two quasi-randomized) with 102 eyes in 61 children. Two trials were conducted in the USA and one trial each in Egypt, Israel, Lebanon and Saudi Arabia. All trials included children aged younger than one year when diagnosed with PCG, and followed them for periods ranging from six months to five years.No two trials compared the same pair of surgical interventions, so we did not perform any meta-analysis. One trial compared trabeculotomy versus goniotomy; a second trial compared combined trabeculectomy-trabeculotomy with mitomycin C versus trabeculectomy-trabeculotomy with mitomycin C and deep sclerectomy; a third trial compared combined trabeculotomy-trabeculectomy versus trabeculotomy; a fourth trial compared one goniotomy versus two goniotomies; a fifth trial compared trabeculotomy versus viscocanalostomy; and the sixth trial compared surgical goniotomy versus neodymium-YAG laser goniotomy. For IOP change and surgical success (defined by IOP achieved), none of the trials reported a difference between pairs of surgical techniques. However, due to the limited sample sizes for all trials (average of 10 children per trial), the evidence as to whether a particular surgical technique is effective and which surgical technique is better still remains uncertain. Adverse events, such as choroidal detachment, shallow anterior chamber and hyphema, were reported from four trials. None of the trials reported quality of life or economic data.These trials were neither designed nor reported well overall. Two trials were quasi-randomized trials and judged to have high risk of selection bias; four trials were at unclear or high risk for performance bias and detection bias; and we judged one trial to have high risk of attrition bias due to high proportions of losses to follow-up. Due to poor study design and reporting, the reliability and applicability of evidence remain unclear. AUTHORS' CONCLUSIONS No conclusions could be drawn from the trials included in this review due to paucity of data. More research is needed to determine which of the many surgeries performed for PCG are effective.

Abstract
Purpose To describe the clinical course of congenital aniridia and to evaluate prognostic factors for visual outcome after long-term follow-up. Methods The medical records of 120 eyes from 60 patients with congenital aniridia were retrospectively reviewed. The prevalence and clinical course of ophthalmic characteristics, systemic disease, refractive errors, and visual acuity were assessed. Prognostic factors for final visual outcomes were analyzed. Results Aniridic keratopathy developed in 82 (69%) of 119 eyes. Macular hypoplasia was observed in 70 eyes of 35 patients (91%). Cataract was observed in 63 of 120 eyes (53%). Nystagmus was present in 41 patients (68% of 60 patients) at the initial visit but decreased in five patients (8% of 60 patients). Ocular hypertension was detected in 19 eyes (20% of 93 eyes), six (32% of 19 eyes) of which developed secondarily after cataract surgery. The mean changes in spherical equivalent and astigmatism during the follow-up period were -1.10 and 1.53 diopter, respectively. The mean final visual acuity was 1.028 logarithm of minimal angle of resolution. Nystagmus and ocular hypertension were identified as prognostic factors for poor visual outcome. Conclusions Identification of nystagmus and ocular hypertension was important to predict final visual outcome. Based on the high rate of secondary ocular hypertension after cataract surgery, careful management is needed.

Abstract
Purpose Studying the role of ultrasound biomicroscopy (UBM) in detection of anterior segment changes in infants with primary congenital glaucoma (PCG). Methods Cross-sectional study that included 25 eyes of 15 patients suffering from PCG and a control group of 15 eyes of ten age- and sex-matched participants. Diagnosis of PCG was based on clinical data (intraocular pressure, corneal diameter, fundus examination and amplitude-modulation scan measurement of axial length). UBM examination was done for all participants for measurement of central corneal thickness, anterior chamber depth, lens thickness, iris thickness (measured 2 mm from the iris root and again at the thickest point near the pupil), zonular length, posterior chamber depth, and angle of anterior chamber. Qualitative evaluation was done for abnormal angle membranes, iris insertion level, and ciliary processes position and configuration. Results Mean age ± standard deviation was 10.32±3.59 months in the study group and 14.54±5.9 months in the control group. The central corneal thickness, anterior chamber depth, zonular length, and angle of anterior chamber were significantly larger in the study group than in the control group, with mean values 700±190 μm, 3.55±0.32 mm, 1.02±0.15 mm, and 58.47°±5.57°, respectively. The posterior chamber depth had a mean of 0.33±0.06 mm, which was significantly smaller than that of the control group. In the study group, the mean iris thickness 2 mm from the iris root was 0.32±0.04 mm, the mean iris thickness at the thickest point near the pupil was 0.38±0.08 mm, and the mean lens thickness was 3.32±0.18 mm. These three parameters were smaller than the control group but the difference was insignificant. Loss of normal iris configuration was detected in all eyes of the study group. Anterior iris insertion was detected in 56% of the eyes in the study group, and abnormal angle membrane was found in 12%. Conclusion UBM is a useful tool for detection of anterior segment changes in PCG, which is helpful especially in cases with opaque cornea or cases with borderline clinical findings.

Abstract
Most children with glaucoma will require surgery in their lifetime, often in their childhood years. The surgical management of childhood glaucoma is however challenging, largely because of its greater potential for failure and complications as compared with surgery in adults. The available surgical repertoire for childhood glaucoma has remained relatively unchanged for many years with most progress owing to modifications to existing surgery. Although the surgical approach to childhood glaucoma varies around the world, angle surgery remains the preferred initial surgery for primary congenital glaucoma and a major advance has been the concept of incising the whole of the angle (circumferential trabeculotomy). Simple modifications to the trabeculectomy technique have been shown to considerably minimise complications. Glaucoma drainage devices maintain a vital role for certain types of glaucoma including those refractory to other surgery. Cyclodestruction continues to have a role mainly for patients following failed drainage/filtering surgery. Although the prognosis for childhood glaucoma has improved significantly since the introduction of angle surgery, there is still considerable progress to be made to ensure a sighted lifetime for children with glaucoma all over the world. Collaborative approaches to researching and delivering this care are required, and this paper highlights the need for more high-quality prospective surgical trials in the management of the childhood glaucoma.

Abstract
PURPOSE Among the options for surgical management of pediatric glaucoma, destruction of the ciliary body reduces aqueous production and, consequently, intraocular pressure (IOP). Compared to more invasive filtering and shunt procedures, cyclodestruction is an attractive option for control of IOP in pediatric glaucomas. METHODS The relative reduction in IOP, duration of effect, and comparable safety and efficacy of transscleral cyclophotocoagulation (TSCP) and endoscopic cyclophotocoagulation (ECP) in pediatric patients with glaucoma was studied in this retrospective chart review. RESULTS A reduction in IOP of 28.6% and 33.2% with TSCP and ECP, respectively, was found. Eyes treated with ECP underwent an average of 3.24 cyclodestructive procedures; eyes treated with TSCP underwent an average of 2.29 cyclodestructive treatments. These differences were not statistically significant. A final success rate of 67.6% after TSCP and 62% after ECP failed to significantly differ between the two groups. Consequently, two-thirds of the patients were able to avoid penetrating surgery and the associated risks after one or more cyclodestructive procedures. CONCLUSIONS TSCP and ECP are safe, effective, and comparable treatments for pediatric glaucomas. The results suggest that TSCP and ECP may be considered first-line therapy to achieve control of IOP in all forms of pediatric glaucoma. [J Pediatr Ophthalmol Strabismus 2014;51(2):120-127.].

Abstract
PURPOSE Few studies have provided epidemiological characteristics of childhood glaucoma in a large, multiethnic population. This information is important if we are to better screen for and characterize this specific type of glaucoma. In this study, we evaluate the characteristics of patients with childhood glaucoma, including glaucoma suspects, as identified through the Dallas Glaucoma Registry (DGR). PATIENTS AND METHODS The DGR catalogs the characteristics of glaucoma patients seen at University of Texas Southwestern Medical Center, an academic tertiary referral center for a large, multiethnic, urban population in the United States. We analyzed these patients with respect to race, medical and surgical treatment, cup-to-disc ratio, intraocular pressure, and visual outcomes. RESULTS The study comprised 376 eyes of 239 childhood glaucoma patients, of whom 19% had primary congenital glaucoma, 4% had primary juvenile glaucoma, 45% had secondary glaucoma, and 31% were glaucoma suspects. Trauma and postsurgical aphakia were the most common causes for secondary glaucoma. Thirty-eight percent of patients were Hispanic, 30% were Caucasian, 21% were African American, 3% were Asian, and 9% were unknown or unreported. Male sex was more common at 56%. Of all eyes with glaucoma, 65% received surgical intervention while 70% required at least one medication for intraocular pressure control. Trabeculotomy and tube-shunt surgery were the most common surgeries performed. Of patients who could have Snellen visual acuity measured, glaucoma suspect eyes had the largest proportion of eyes (96%) with good visual acuity (better than 20/40) while primary congenital glaucoma eyes had the smallest proportion (41%) with good visual acuity. Secondary glaucoma eyes had the largest proportion of eyes (30%) with poor visual acuity (worse than count fingers). CONCLUSION The most common etiologies of childhood glaucoma were primary congenital glaucoma and secondary causes including trauma and postsurgical aphakia. A high proportion of glaucoma patients were of Hispanic background, reflecting the patient population studied. Trabeculotomy and tube-shunt surgery were the most common surgical interventions performed.

Abstract
PURPOSE To study the additive value of deep sclerectomy to the procedure of combined trabeculotomy-trabeculectomy with mitomycin C (CTTM) for the treatment of primary congenital glaucoma. STUDY DESIGN This study is a prospective, randomized case series. PATIENTS AND METHODS The study was conducted on 20 eyes of 20 children with primary congenital glaucoma presenting to the Department of Ophthalmology of the Alexandria Main University Hospital. Preoperative examination under anesthesia was followed by surgical intervention. Postoperative examinations were conducted immediately after surgery and at 1, 2, 3, 6, 9, and 12 months. Intraoperative and postoperative complications, as well as operative time, were recorded. RESULTS The mean (±SD, range) age of the study patients in the CTTM group and in the combined trabeculotomy-trabeculectomy with mitomycin C with deep sclerectomy (CTTM-DS) group was 4.7 (±2.0, 2-8) and 7.0 (±3.8, 3-13) months, respectively. The mean (±SD, range) preoperative intraocular pressure (IOP) in the CTTM and CTTM-DS groups was 16.7 (4.3, 10-26) and 16.4 (8.4, 8-36), respectively, and these dropped at 12 months of follow-up to 4.9 (2.0, 2-8) and 5.6 (3.3, 2-10), respectively. The mean (±SD, range) of the duration of the operation in the CTTM and the CTTM-DS was 57 (±8, 50-71) min and 53 (±7, 42-64) min, respectively (P=0.428). Two eyes (20%) in the CTTM-DS group developed hypotony disc edema at the first 2 months and resolved spontaneously thereafter. No other complications were noted in either of the groups. CONCLUSION The addition of deep sclerectomy to the procedure of CTTM in pediatric glaucoma surgery facilitates the finding of Schlemm's canal, shortens the duration of surgery, and is not associated with any additional complications. Hence, the author recommends the addition of deep sclerectomy to CTTM surgery for primary congenital glaucoma.

Abstract
PURPOSE To compare circumferential trabeculotomy performed with an illuminated microcatheter with standard goniotomy for the treatment of congenital glaucoma. METHODS The short-term results of catheter-assisted trabeculotomy with an illuminated microcatheter were retrospectively compared with those of goniotomy in patients treated for congenital glaucoma. Success with either approach was defined as an intraocular pressure (IOP) <21 mm Hg with at least a 30% reduction from preoperative pressure levels at 12-month follow-up. Complete success was defined when the target IOP levels were reached without the use of antiglaucoma medication, and qualified success was defined when antiglaucoma drops were required to meet this level of IOP. RESULTS A total of 24 eyes of 20 patients were included. Microcatheter-assisted circumferential trabeculotomy demonstrated a 91.6% qualified and 83.3% unqualified success rate with 12-month follow-up that exceeded the 53.8% qualified and 46.2% unqualified success rate of conventional goniotomy. CONCLUSIONS In congenital glaucoma, during the first year after surgery, trabeculotomy performed with an illuminated microcatheter appears to be more effective than ab interno goniotomy. No complications were seen in either group; however, the follow-up was relatively short.

El Gendy NMS, Song JC. Long term comparison between single stage Baerveldt and Ahmed glaucoma implants in pediatric glaucoma. Saudi J Ophthalmol 2012; 26:323-6. [PMID: 23961013 DOI: 10.1016/j.sjopt.2012.06.003] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2012] [Revised: 06/13/2012] [Accepted: 06/26/2012] [Indexed: 11/19/2022] Open
Abstract
PURPOSE To compare the long term intraocular pressure control in pediatric glaucoma patients who underwent single stage Baerveldt glaucoma valve and Ahmed glaucoma valve S2 implantation. STUDY DESIGN A retrospective study was conducted to analyze the data of patients with single stage Baerveldt glaucoma valve and Ahmed valve implantation at Children Hospital Los Angeles. METHODS Medical records of patients were reviewed retrospectively and divided into two groups. All cases received single stage valve implantation in which the tube was inserted primarily into the anterior chamber. In cases with Baerveldt implants, the silicone tube was ligated near its plate location with a single absorbable suture. Group 1 included patients with Baerveldt glaucoma implant model BG 101-350, while group 2 included patients with Ahmed valve implant model S-2. Patients' data collected ranged over the period from 2001 to 2008. The minimum follow up period was 6 month; maximum follow up period was 8 years. All patients were below 18 years of age. Success was considered if last postoperative IOP was between 8 and 24 mm Hg (with or without medications), no additional glaucoma surgery after valve implantation, and absence of visually significant complications. RESULTS Group 1 included 20 cases and group 2 included 11 cases. Long term success rate based on criterion defined was 80% for group 1 (Baerveldt) with average IOP postoperatively on last follow-up of 19.6 mm Hg. In group 2 (Ahmed), average postoperative pressure was 24 mm Hg with 6 out of 11 considered successful based on criterion giving 54.5% success rate. CONCLUSION In the long term, single stage Baerveldt implantation appears to control pressure well in pediatric glaucoma.

Abstract
PURPOSE To evaluate the role of episcleral venous pressure (EVP) in the pathogenesis of glaucoma associated with Sturge-Weber syndrome (SWS). METHODS EVPs were determined prospectively using an episcleral venomanometer in 22 eyes of 11 patients aged 8-18 years with SWS with or without glaucoma. Pressure measurements in the glaucomatous eyes of patients with SWS were compared to those of patients with facial port wine marks but no glaucoma and to the contralateral uninvolved eye in both groups. RESULTS EVP in eyes with glaucoma (mean, 20.9 mm Hg) was significantly higher (P < 0.01) than EVP in contralateral uninvolved eyes (mean, 9.6 mm Hg). In patients with unilateral port wine mark and no glaucoma, EVP was normal for ipsilateral and contralateral eyes (mean, 8.6 mm Hg and 9.6 mm Hg, respectively). CONCLUSIONS Our data support the hypothesis that elevated EVP plays an important role in eyes with SWS glaucoma.

Abstract
Pediatric glaucoma is potentially a blinding disease. Although goniotomy and trabeculotomy are associated with good early success rates, eventually 20% of these procedures fail and many children will require additional surgery to control the IOP in the long-term. In this review, we reported that adequate IOP control can be achieved with the placement of Ahmed glaucoma valve and can last 5 or more years. However, most patients will need one or more glaucoma medications at some point after surgery. In addition, the implants may be associated with pupillary irregularities, lenticular opacification as well as tube-related complications, particularly in the first year of life, as the globe is enlarging with age.

Abstract
PURPOSE To evaluate the outcomes of 360-degree suture trabeculotomy in childhood glaucoma with poor prognosis. METHODS A nonrandomized, retrospective chart review was performed on pediatric patients (younger than 18 years of age) treated with a 360-degree suture trabeculotomy for glaucoma. The cases were categorized into the following groups: (1) primary congenital glaucoma with birth-onset presentation accompanied by corneal clouding noted at birth, (2) primary congenital glaucoma with onset or presentation after 1 year of age, (3) primary congenital glaucoma with previous failed goniotomy surgery, (4) infantile-onset glaucoma following congenital cataract surgery, and (5) infantile-onset glaucoma with associated ocular/systemic anomalies. RESULTS A total of 45 eyes of 33 patients were analyzed. The mean preoperative intraocular pressure (IOP) was 34.3±6.7 mm Hg on an average of 1.5 medications. Median age at time of surgery was 7 months. Mean final IOP (median last follow-up or failure, 12 months) was 22.2±7.1 mm Hg on an average of 1.5 medications. The probability of success according to time after surgery was 87% at 6 months, 63% at 1 year, and 58% at 2 years. Kaplan-Meier analysis of Groups 1-4 versus Group 5 failed to demonstrate a statistically significant difference (p=0.13). Of 5 eyes with port wine mark-related glaucoma, 2 had a large (>50%), persistent postoperative hyphema, and concurrent vitreous hemorrhage. CONCLUSIONS Children with a range of ocular pathologies can be successfully treated with 360-degree suture trabeculotomy. Further evaluation of this surgical technique in primary congenital glaucoma and open-angle glaucoma following congenital cataract surgery is warranted.

Abstract
OBJECTIVE To describe the incidence and clinical characteristics of childhood glaucoma in a defined population of the United States. METHODS The medical records of all pediatric patients younger than 20 years living in Olmstead County, Minnesota, from January 1, 1965, through December 31, 2004, who met diagnostic criteria for glaucoma or glaucoma suspect were reviewed. RESULTS Thirty children were diagnosed as having glaucoma during the 40-year study period. The incidence of childhood glaucoma was 2.29 (95% confidence interval, 1.47-3.12) per 100,000 residents younger than 20 years, with the following types and incidences: 19 acquired (1.46/100,000; 0.80-2.12), 6 secondary (0.45/100,000; 0.08-0.82), and 5 primary glaucoma (0.38/100,000; 0.05-0.72). The birth prevalence of primary congenital glaucoma during the 40-year period was 1 per 68 254 residents younger than 20 years or 1.46 per 100,000 (95% confidence interval, 0.03-8.16). Twenty-four individuals with glaucoma suspect were also identified, yielding an incidence of 1.9 per 100,000 residents younger than 20 years (95% confidence interval, 1.14-2.66). CONCLUSION The incidence of childhood glaucoma in this population was 2.29 per 100,000 residents younger than 20 years or 1 per 43 575 residents younger than 20 years. Acquired and secondary forms of glaucoma were the most common, whereas congenital and juvenile glaucoma were rare.

Abstract
PURPOSE To examine the efficacy of a sequential tube shunt versus transscleral diode cyclophotocoagulation following failure of an initial tube shunt on maximal medical therapy in treatment of refractory childhood glaucoma. METHODS A nonrandomized retrospective chart review was conducted of 17 eyes of 14 pediatric patients (less than 18 years old) with refractory glaucoma treated with either sequential tube shunt (Group A) or diode cyclophotocoagulation (Group B) following initial failed tube shunt. Success was defined as an intraocular pressure < or =22 mm Hg on medical therapy, no visually devastating complications, and no further glaucoma surgery performed or recommended. RESULTS Of the 17 eyes, 8 had a sequential tube shunt and 9 underwent diode cyclophotocoagulation as a secondary procedure. Kaplan-Meier analysis demonstrated a successful outcome of 75% and 62.5% at 12 months and 24 months, respectively, for Group A, and 66.7% at both 12 months and 24 months for Group B (p = 0.48). Corneal decompensation or graft failure was noted in 3/8 eyes (38%) in Group A. Cataract surgery was performed in 2/5 phakic eyes (40%) in Group B. One eye in each group progressed to no light perception. CONCLUSIONS Diode cyclophotocoagulation and sequential tube shunt following primary tube shunt failure in childhood glaucoma showed similar efficacy and complication rates. However, the small sample size of this study warrants further evaluation of these 2 procedures following failure of a tube shunt device in pediatric glaucoma.

Abstract
PURPOSE To evaluate childhood filtration surgery when using releasable sutures, antimetabolites, and bleb-needling with 5-fluorouracil (5FU). METHODS Retrospective case note review of 30 patients (38 eyes) with childhood glaucoma presenting between 1999 and 2004 to a tertiary pediatric ophthalmology center. Either trabeculectomy or combined trabeculotomy-trabeculectomy using antimetabolites, releasable sutures, and bleb modification was performed. Successful outcomes for survival analysis were measured intraocular pressures < or =21 mmHg, with two or less topical medications. RESULTS Patients under 1 year old had trabeculotomy-trabeculectomy; the remainder had trabeculectomy alone. One case of primary congenital glaucoma had trabeculotomy-trabeculectomy at 24 months. Eighty-nine percent had previous failed glaucoma surgery. Twenty-five patients (33 eyes) had primary congenital glaucoma; 5 patients (5 eyes) had secondary glaucoma (aphakia or pseudophakia). Mean follow-up was 22.9 months (5.2-68.5). Sixty-six percent of all eyes had suture-release and 68% had bleb-needling (mean, 1.9 times). Five eyes (13%) needed further drainage tube surgery. Complications were early postoperative hypotony in three cases, requiring anterior chamber reinflation (mean age, 7.4 months at the time of surgery), two cases of transient wound leak, but no bleb-related complications or endophthalmitis. No blebs were avascular, or thin and cystic. Cumulative success was 75% for primary, but only 21% for secondary glaucoma at final follow-up. CONCLUSIONS Antimetabolite and releasable augmentation of filtration surgery appear to give favorable outcomes in the treatment of refractory primary pediatric glaucomas. Secondary glaucomas after cataract surgery do not show good long-term success. There were no major or sight-threatening complications in our series; no eyes developed cystic avascular blebs or bleb-related infections.
