Lens Thickness in Infants and Children with Cataracts. OPHTHALMOLOGY SCIENCE 2025; 5:100588. [PMID: 39318710 PMCID: PMC11421318 DOI: 10.1016/j.xops.2024.100588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/29/2024] [Accepted: 07/22/2024] [Indexed: 09/26/2024]
Abstract
Purpose The purpose of this study was to determine the association between lens thickness and cataract in participants aged 0 to 5 years. Design This was a prospective, multicenter, case-control study. Participants We enrolled 118 participants (171 eyes) aged 0 to 5 years, mean age 14.6 ± 17.0 months, range 0 to 60 months. Methods Lens thickness was measured on 342 ultrasound biomicroscopy (UBM) images. Main Outcome Measures Lens thickness; feasibility of lens thickness measurement from UBM images. Results The mean lens thickness among noncataracts was 3.60 ± 0.17 mm, compared with 3.16 ± 0.61 mm among cataracts (P < 0.0001). Lens thickness <3.5 mm was significantly associated with increased odds of cataract; adjusted odds ratio = 5.99 (95% confidence interval, 2.41-14.88; P < 0.0003) among participants age 0 to 7 months. Lens thickness was significantly associated with cataract laterality among participants age 0 to 7 months (P < 0.0001). Conclusions Quantitative UBM can be used to evaluate lens thickness in infants and children with congenital cataracts. The lens in congenital cataract eyes was thinner than that of controls among infants. Abnormal lens thickness was significantly associated with cataract. Future longitudinal studies will examine the association between lens thickness and postcataract surgery outcomes.

Abstract
PURPOSE To report timing of diagnosis and treatment of glaucoma following cataract surgery (GFCS) in a large cohort of infants undergoing cataract surgery at a tertiary care center. STUDY DESIGN Cross-sectional study. PARTICIPANTS All consecutive infants that underwent cataract surgery over a 30-year period from January 1991 to December 2021 were included if they had at least 1 year follow-up. METHODS The data collection included age at time of cataract surgery, presence of associated ocular or systemic conditions, age at diagnosis of GFCS, and treatment required to control GFCS. Glaucoma diagnosis required intraocular pressure (IOP) > 21 mmHg on > 2 visits with glaucomatous optic nerve head changes and/or visual field changes, or in young children, other anatomic changes such as corneal enlargement or haze or accelerated axial elongation and myopic shift. MAIN OUTCOME MEASURES The incidence of GFCS was calculated. Linear regression was performed to assess the effect of age at time of cataract surgery. Analysis of risk factors and treatment modalities was performed using univariate and multivariate analysis. RESULTS Three hundred eighty-three eyes (260 patients) were analyzed. Median age at surgery was 52 days and median follow-up, 8 years. Glaucoma following cataract surgery was noted in 27% (104/383 eyes; median age at surgery, 45 days; median follow-up, 13 years.) Young age at surgery (< 3 months) was the greatest risk factor (P = 0.001) but the incidence was similar for infants operated in the first, second, or third month of life (25%, 36%, 40%, respectively, P = 0.4). Microcornea (41%, P < 0.0001), poorly dilating pupils (25%, P = 0.001), persistent fetal vasculature (PFV, 13%; P = 0.8), or anterior segment dysgenesis (3%, P = 0.02) were considered as additional risk factors. Surgical intervention was needed for 73% (24/33) eyes with early-onset GFCS compared with 14% (10/71) eyes with later-later onset GFCS (P < 0.0001). Medical treatment was effective in 86% with later-onset GFCS (P = 0.006). CONCLUSIONS The incidence of GFCS was 27%, and timing of diagnosis occurred in a bimodal fashion. Early-onset GFCS usually requires surgical intervention; medical treatment is effective for later-onset GFCS. Cataract surgery within the first 3 months of life, microcornea, and poorly dilating pupils were major risk factors.

Abstract
AIMS To report the incidence and associated risk factors for developing suspected and definitive glaucoma after bilateral congenital cataract (CC) removal with a 5-year follow-up. METHODS Secondary analysis of a prospective longitudinal cohort study. Bilateral CC patients who had undergone cataract surgery between January 2011 and December 2014 at Zhongshan Ophthalmic Centre were recruited. Suspected glaucoma was defined as persistent ocular hypertension requiring medical treatment. Definitive glaucoma was defined as accompanied by the progression of glaucomatous clinical features. According to postoperative lens status in 5 years follow-up: 130 eyes in the aphakia group; 219 in the primary intraocular lens (IOL) implantation group and 337 in the secondary IOL implantation group. The Kaplan-Meier survival and Cox regression analyses were used to explore the cumulative incidence and risk factors for suspected and definitive glaucoma. RESULTS Three hundred fifty-one children (686 eyes) with bilateral CCs were enrolled in the study. The mean age at surgery was 1.82±2.08 years, and the mean follow-up duration was 6.26±0.97 years. Suspected and definitive glaucoma developed at a mean time of 2.84±1.75 years (range 0.02-7.33 years) postoperatively. The cumulative incidence of suspected and definitive glaucoma was 9.97% (35 of 351 patients), including 6.12% (42 eyes) for definitive glaucoma and 2.48% (17 eyes) for suspected glaucoma. Microcornea (HR 4.103, p<0.0001), CC family history (HR 3.285, p=0.001) and initial anterior vitrectomy (HR 2.365 p=0.036) were risk factors for suspected and definitive glaucoma. Gender, age at surgery, intraocular surgery frequency, length of follow-up and frequency of neodymium-doped yttrium aluminumaluminium garnet laser were non-statistically significant. Primary IOL implantation was a protective factor (HR 0.378, p=0.007). CONCLUSIONS Identifying suspected and definitive glaucoma after bilateral CC surgery can lower the risk of secondary blindness in children. Patients with related risk factors need to pay more attention and thus reach early intervention and treatment during clinical practice. Primary IOL implantation may be a potential protective factor, need more clinical trials to be verified. TRIAL REGISTRATION NUMBER NCT04342052.

Late-onset glaucoma following congenital cataract surgery: Occurrence, visual acuity and risk factors: A 37-year longitudinal follow-up. Acta Ophthalmol 2023; 101:170-176. [PMID: 36036699 DOI: 10.1111/aos.15241] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 06/11/2022] [Accepted: 08/19/2022] [Indexed: 11/27/2022]
Abstract
PURPOSE The aim of this study was to determine the prevalence of late-onset glaucoma after surgery for congenital cataract in a cohort with long-term follow-up and to evaluate visual development following the diagnosis of postoperative glaucoma in comparison with no glaucoma development. METHODS All children born between 1980 and 1997 in the western counties of Sweden who had undergone congenital cataract surgery were included (patients n = 77, eyes n = 122). Cataract was considered congenital if there was no proof of clear lens at birth. Medical records were reviewed with regard to onset of glaucoma, age at surgery, surgical technique, coexisting eye anomalies and changes in visual acuity. Glaucoma was considered late onset if occurring after 1 year following surgery. RESULTS Total glaucoma prevalence was 14.8%, including late (10.7%) and early onset (4.1%), with a mean follow-up of 23.2 ± 6.6 years. Microphthalmos was a significant risk factor for developing glaucoma (RR 7.75, p < 0.001). Bilaterally treated eyes had a mean visual acuity of 0.43 ± 0.33 (decimal value) at the last follow-up. With glaucoma, mean visual acuity was 0.19 ± 0.17 (decimal value). Treated eyes of patients with unilateral cataract surgery had a lower visual acuity. CONCLUSIONS Life-long follow-up of all patients who have undergone surgery for congenital cataract in childhood is recommended. Annual check-ups of adults, including measurements of IOP and visual acuity, are recommended for patients with microphthalmos and/or who had surgery <3 months of age.

Abstract
Glaucoma following cataract surgery (GFCS) remains a serious postoperative complication of pediatric cataract surgery. Various risk factors, including age at lensectomy, intraocular lens implantation, posterior capsule status, associated ocular/systemic anomaly, additional intraocular surgery, and a family history of congenital cataract and GFCS, have been reported. However, the optimal surgical approach remains unclear. This review evaluates the diagnostic criteria, classification, risk factors, mechanism, and surgical management, especially the efficacy of minimally invasive glaucoma surgery, in GFCS, and aims to propose an optimal clinical management strategy for GFCS. The results of our review indicate that ab interno trabeculotomy (goniotomy) may be the most appropriate first-line treatment for GFCS.

Abstract
PURPOSE To describe the prevalence and clinical characteristics of a large cohort of childhood glaucoma patients that presented to a tertiary Egyptian children's hospital using the childhood glaucoma research network (CGRN) classification. METHODS A retrospective review of the medical records of all patients ≤ 14 years with a diagnosis of childhood glaucoma or glaucoma suspects who presented to Children's Hospital between January 2014 to December 2019 was conducted. Data collected included age at the time of diagnosis, gender, laterality, prenatal history, parental history, including consanguinity, intraocular pressure, horizontal corneal diameter, and cup-to-disc ratio. RESULTS A total of 1113 eyes of 652 patients with diagnoses of either childhood glaucoma or glaucoma suspects were included in the study. Six hundred and sixteen patients (94%) were born full-term. A history of positive parental consanguinity was identified in 334 patients (51.2%). Almost 60% of patients were males. Primary congenital glaucoma (PCG) was the most prevalent diagnosis (68.2%), followed by glaucoma suspects (10.4%) and glaucoma following cataract surgery (GFCS) (8.4%). Juvenile open-angle glaucoma was the least prevalent category (0.3%). Other categories including glaucoma associated with non-acquired systemic disease, glaucoma associated with non-acquired ocular disease, and glaucoma associated with acquired conditions represented 5.8%, 4.7%, and 1.9%, respectively. CONCLUSIONS PCG is the most common form of glaucoma in Egypt. More than half of the pediatric glaucoma patients had a positive history of parents' consanguinity.

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
Abstract
Background
This study aimed to identify the incidence of and risk factors for postoperative glaucoma-related adverse events at various time points after congenital cataract surgery.
Methods
This retrospective cohort study enrolled 259 eyes from 174 patients (surgical age ≤ 7 years) who underwent congenital cataract surgery. All surgical procedures were conducted at the Eye Hospital of Wenzhou Medical University between May 2011 and March 2019. Patients were classified into group 1 [primary intraocular lens (IOL) implantation, N = 111 eyes], group 2 (secondary IOL implantation, N = 85 eyes), and group 3 (no IOL implantation, N = 63 eyes). We recorded demographic factors and incidence and risk factors for glaucoma-related adverse events.
Results
Glaucoma-related adverse events occurred in 21 (8.1%) eyes, whereas 27 (10.4%) eyes developed steroid-induced ocular hypertension. The percentage of glaucoma-related adverse events was 0%, 1.2%, 1.2%, 1.6%, 4.0%, and 8.9% at 1 month, 6 months, 1 year, 2 years, 3 years and 4 years after surgery, respectively. Sixteen (18.8%), five (7.9%), and zero eyes developed glaucoma-related adverse events in groups 2, 3, and 1, respectively. Family history of congenital cataract [hazard ratio (HR), 50.463; 95% confidence interval (CI), 7.051–361.139; P < 0.001], preoperative central corneal thickness (CCT) [HR, 1.021; 95% CI, 1.009–1.034; P = 0.001], preoperative horizontal corneal diameter (HCD) [HR, 3.922; 95% CI, 1.558–9.804; P = 0.004], and preoperative lens thickness (LT) [HR, 3.745; 95% CI, 1.344–10.417; P = 0.012] were identified as predictors of postoperative glaucoma-related adverse events.
Conclusions
Family history of congenital cataract, thicker preoperative CCT, smaller preoperative HCD, and thinner preoperative LT are the main risk factors of postoperative glaucoma-related adverse events. Regular monitoring of children after cataract surgery with these risk factors may help ophthalmologists detect susceptible individuals and provide timely interventions in the clinic.

Abstract
Introduction Congenital cataract (CC) can cause childhood visual impairment, even after CC surgery, due to subsequent occurrence of glaucoma. The post-CC-surgery glaucoma study results vary, due largely to the lack of a sufficient number of population-based cohort studies. This study herein proposed aims to assess the incidence and risk factors of post-CC-surgery glaucoma in a nationwide cohort. The clinico-demographic factors associated with outcomes of post-CC-surgery glaucoma will be investigated as well. Materials and methods This population-based, nested case-control study is planned as part of the Korean Nationwide Epidemiological Study for Childhood Glaucoma (KoNEC). Data for a nationwide retrospective cohort representative of the years 2008 to 2018 will be extracted from the National Institutes of Health database, which includes demographic information, diagnoses and medical visits as well as procedures, records of prescriptions, and comorbidities. Among the patients whose first CC diagnosis was made before age 1, only those who underwent surgery for CC will be included in the study. The rate of occurrence of post-CC-surgery glaucoma will be determined based on a Poisson distribution. Also, for cumulative incidence plotting, the Kaplan-Meier method will be used. To identify risk factors for occurrence and poor outcomes of post-CC-surgery glaucoma, we will perform a multivariable regression analysis of matched samples. The detailed patterns of post-CC-surgery glaucoma management will be studied as well. OSF registration number DOI 10.17605/OSF.IO/AWTEC.

Abstract
Preterm babies with retinopathy of prematurity (ROP) can become blind if they do not receive appropriate timely intervention. The presence of cataract in these individuals in addition to visual deprivation amblyopia, also delays proper screening, adequate treatment, and makes follow-up assessment difficult. Anatomical differences in these infants and amblyopia management, especially in unilateral cataract, are other important concerns, and hence, management of these cases with cataract and ROP is challenging. In this review, studies where ROP cases were associated with cataract, were evaluated with a focus on preterm individuals less than 6 months age. Preterm babies are at increased risk of developing cataract because of systemic factors. In addition, those with ROP may have cataract associated with retinal detachment or treatment received. The type of cataract, risk factors, and pathophysiology associated with each cause varies. This review highlights these different aspects of cataract in ROP including causes, pathophysiology, types of cataracts, and management. The management of these cases is critical in terms of the timing of cataract surgery and the challenges associated with surgery and posterior segment management for ROP. Anatomical differences, preoperative retina status, pupillary dilatation, neovascularization of iris in aggressive posterior ROP, fundus examination, amblyopia, and follow-up are various important aspects in the management of the same. The preoperative workup, intraoperative challenges, postoperative care, and rehabilitation in these individuals are discussed.

Abstract
PURPOSES The present meta-analysis compared the postoperative visual performance of primary intraocular lens (IOL) implantation and primary aphakia in cataract infants. METHODS PubMed, Embase, Science Direct and Cochrane Library were searched, and postoperative visual acuity (VA) and complications were extracted and pooled. RESULTS Three randomised controlled trails (RCTs) and five retrospective studies were included. The postoperative VA of children younger than 4.5 years in primary IOL group was better than that in primary aphakia group [MD = -0.14, 95% CI: (-0.23, -0.06), P = .90]. The subgroup analysis based on RCTs and on unilateral cataract surgery revealed the same result. There was no significant difference in the incidence of glaucoma, strabismus, retinal detachment and nystagmus between primary IOL group and primary aphakia group [OR = 1.02, 95% CI: (0.62, 1.68), P = .48 for glaucoma; OR = 0.76, 95% CI: (0.30, 1.90), P = .05 for strabismus; OR = 0.49, 95% CI: (0.07, 3.30), P = .34 for retinal detachment; OR = 1.26, 95% CI: (0.68, 2.36), P = .92 for nystagmus]. The proportion of patients requiring postoperative visual axis opacification (VAO) clearing was higher in primary IOL group than that in primary aphakia group [OR = 9.22, 95% CI: (4.74, 17.96), P = .16]. CONCLUSION For infants under 2 years of age, primary IOL implantation would provide more visual benefits compared with primary aphakia did, though the benefits would taper off with the age reaching 4.5 years. Moreover, the current study revealed a higher VAO incidence r in primary IOL implantation group.

Changes in Intraocular Pressure and Anterior Chamber Angle After Congenital Cataract Extraction. J Glaucoma 2021; 30:61-64. [PMID: 32969922 DOI: 10.1097/ijg.0000000000001681] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Accepted: 09/03/2020] [Indexed: 12/27/2022]
Abstract
PRECIS Anterior chamber angle (ACA) narrowing continues to occur for at least 2 years after congenital cataract surgery. Risk factors for intraocular pressure (IOP) elevation after congenital cataract surgery were higher central corneal thickness (CCT) and surgery at <2 months. PURPOSE The purpose of this study was to study the changes in IOP and in the ACA during the first 2 years after pediatric cataract surgery and to determine risk factors for such changes. PATIENTS AND METHODS A retrospective observational study was done on infants who underwent pediatric cataract surgery in Cairo University Hospitals and completed a 1-year follow-up. Demographic and clinical characteristics were recorded including age at surgery, sex, corneal diameter, CCT pupil diameter, IOP, gonioscopic findings, presence of persistent hyperplastic primary vitreous, surgical approach, primary intraocular lens implantation, and perioperative subconjunctival steroid injection. Changes in IOP and in the ACA were recorded, and the risk factors for such changes were analyzed. RESULTS Postoperative IOP elevation >18 mm Hg occurred in 23 eyes of 206 eyes (11%), who completed Year 1 and in 9 (13%) of 86 eyes who completed Year 2. Risk factors for IOP elevation were larger preoperative CCT (P=0.01) in Year 1, and younger age at surgery (P=0.01), and aphakia (P=0.05) in Year 2. In multivariate analysis only younger age at surgery was a risk factor for IOP elevation in Year 2. ACA narrowing occurred in 49% and in 21% of the examined eyes in Years 1 and 2, respectively. Aphakia was not a significant risk factor of angle narrowing in Years 1 and 2 (P=0.17 and 0.42, respectively). CONCLUSIONS Higher preoperative CCT was a risk factor for early-onset IOP elevation. Surgery at >2 months was associated with lower susceptibility to late-onset IOP elevation.

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

Abstract
Glaucoma is a common and sight-threatening complication of pediatric cataract surgery Reported incidence varies due to variability in study designs and length of follow-up. Consistent and replicable risk factors for developing glaucoma following cataract surgery (GFCS) are early age at the time of surgery, microcornea, and additional surgical interventions. The exact mechanism for GFCS has yet to be completely elucidated. While medical therapy is the first line for treatment of GFCS, many eyes require surgical intervention, with various surgical modalities each posing a unique host of risks and benefits. Angle surgical techniques include goniotomy and trabeculotomy, with trabeculotomy demonstrating increased success over goniotomy as an initial procedure in pediatric eyes with GFCS given the success demonstrated throughout the literature in reducing IOP and number of IOP-lowering medications required post-operatively. The advent of microcatheter facilitated circumferential trabeculotomies lead to increased success compared to traditional <180° rigid probe trabeculotomy in GFCS. The advent of two-site rigid-probe trabeculotomy indicated that similar results could be attained without the use of the more expensive microcatheter system. Further studies of larger scale, with increased follow-up, and utilizing randomization would be beneficial in determining optimum surgical management of pediatric GFCS.

Abstract
Aims and objectives This study aimed at describing the characteristics and outcomes of pediatric glaucoma patients in a university hospital in Lebanon and comparing them between primary congenital glaucoma (PCG) and secondary glaucoma. Materials and methods Sixty-four eyes of 40 pediatric glaucoma patients with a follow-up of 1 year or more were reviewed. Parameters were studied for both PCG and secondary glaucoma groups. Three major outcomes were considered: intraocular pressure (IOP) control, final best-corrected visual acuity (BCVA), and the proportion of failed angle surgeries. Results Sixty-four eyes were included divided into 29 PCG and 35 secondary glaucoma eyes, followed up for a mean of 6.6 ± 4.7 years. Eyes with PCG presented earlier, with a higher initial IOP and underwent earlier surgery than their secondary glaucoma counterparts. Although 85.9% of all eyes achieved good IOP control, 44.4% of them had a BCVA ≥20/50 with PCG having a better visual prognosis. Secondary glaucoma eyes needed more medications at the end of their follow-up. In this group, it was shown that a later age at first surgery, unilateral disease, and multiple surgeries were associated with a BCVA < 20/50. Conclusion Patients with PCG presented earlier and with a higher IOP than secondary glaucoma; they were also operated on earlier. Both groups demonstrated good IOP control at the end of the follow-up period with PCG eyes having a superior visual outcome. Secondary glaucoma eyes required a higher number of medications at their final visit. In this population, multiple surgeries, unilateral disease, and a delayed first surgery conferred a poorer visual prognosis. Clinical significance Data regarding the characteristics of pediatric glaucoma, especially in the Middle East, are scarce. Our study sheds the light on the presentation of different types of pediatric glaucoma and their outcomes namely IOP control and visual acuity.

Abstract
Importance Glaucoma can occur following cataract removal in children, and determining the risk for and factors associated with glaucoma and glaucoma suspect in a large cohort of children after lensectomy can guide clinical practice. Objective To estimate the incidence of glaucoma and glaucoma suspect and describe its management in the first year following lensectomy in children before 13 years of age. Design, Setting, and Participants A multicenter clinical research registry containing data for 1361 eyes of 994 children who underwent unilateral or bilateral lensectomy between June 2012 and July 2015 at 1 of 61 sites in the United States (n = 57), Canada (n = 3), and the United Kingdom (n = 1). Patients were eligible for inclusion in the study if they were enrolled in the registry within 45 days after lensectomy and had at least 1 office visit between 6 and 18 months after lensectomy. Patient data were reviewed, and glaucoma and glaucoma suspect were diagnosed by investigators using standardized criteria. Statistical analysis was performed between June 2017 and August 2019. Exposures Clinical care 6 to 18 months after lensectomy. Main Outcomes and Measures Incidence risk using standardized definitions of glaucoma and glaucoma suspect after lensectomy. Results Among 702 patients included in this cohort study, 353 (50.3%) were male and 427 (60.8%) were white; mean age at lensectomy was 3.4 years (range, 0.04-12.9 years). After lensectomy, glaucoma or glaucoma suspect was diagnosed in 66 of 970 eyes (adjusted overall incidence risk, 6.3%; 95% CI, 4.8%-8.3%). Glaucoma was diagnosed in 52 of the 66 eyes, and glaucoma suspect was diagnosed in the other 14 eyes. Mean age at lensectomy in these 66 eyes was 1.9 years (range, 0.07-11.2 years), and 40 of the 66 (60.6%) were eyes of female patients. Glaucoma surgery was performed in 23 of the 66 eyes (34.8%) at a median of 3.3 months (range, 0.9-14.8 months) after lensectomy. The incidence risk of glaucoma or glaucoma suspect was 15.7% (99% CI, 10.1%-24.5%) for 256 eyes of infants 3 months or younger at lensectomy vs 3.4% (99% CI, 1.9%-6.2%) for 714 eyes of infants older than 3 months (relative risk, 4.57; 99% CI, 2.19-9.57; P < .001) and 11.2% (99% CI, 7.6%-16.7%) for 438 aphakic eyes vs 2.6% (99% CI, 1.2%-5.6%) for 532 pseudophakic eyes (relative risk, 4.29; 99% CI, 1.84-10.01; P < .001). No association was observed between risk of developing glaucoma or glaucoma suspect and any of the following variables: sex, race/ethnicity, laterality of lensectomy, performance of anterior vitrectomy, prelensectomy presence of anterior segment abnormality, or intraoperative complications. Conclusions and Relevance This study found that glaucoma or glaucoma suspect developed in a small number of eyes in the first year after lensectomy and may be associated with aphakia and younger age at lensectomy. Frequent monitoring for signs of glaucoma following lensectomy is warranted, especially in infants 3 months or younger at lensectomy and in children with aphakia after lensectomy.

Abstract
PURPOSE The aim was to report cumulative incidence and time of onset of postoperative glaucoma in a paediatric early cataract surgery cohort. METHODS Data were retrieved from the Pediatric Cataract Register (PECARE), a prospective register of Swedish cataract operations before 8 years of age. All eyes with surgery between January 2007 and December 2014 and a registered follow-up were included. Cataracts caused by uveitis, trauma or coexisting congenital glaucoma were excluded. Glaucoma was defined as early onset if diagnosed within a year after surgery and late onset if diagnosed later. RESULTS The study included 288 eyes in 207 children (106 girls), 81 with bilateral and 126 with unilateral cataracts, with a mean follow-up of 3.31 ± 1.77 years. Of the 288, 168 (58.3%) had surgery before 3 months of age; most of these 92.3% (155/168) were defined as dense, 208 (72.2%) were below 1 year of age. Cumulative incidence of surgically treated glaucoma among individuals was 23.7% (49/207). Median time to glaucoma onset was 0.91 years (range: 0.05-4.97 years) for eyes. Early-onset glaucoma was found in 98 % (63/64), and late onset in 2% (1/64). CONCLUSION In this paediatric cataract cohort, a majority of eyes had surgery before 3 months of age (58.3%). Secondary glaucoma-onset peaked within the first postoperative year, with a cumulative incidence of 23.7%. Surgery performed after the first month of life, resulted in a lower glaucoma rate. Long-term follow-up will reveal whether the low rate of late-onset glaucoma with early surgery will last, and if so, the consequences.

Abstract
PURPOSE To determine predictors of secondary glaucoma and poor visual outcome in children undergoing cataract surgery with bag-in-the-lens (BIL)-IOL implantation. METHODS Medical records were retrospectively analysed for children with primary implantation with BIL-IOL during 2009-2013. RESULTS The study included 109 eyes. Median age at surgery was 2.5 years (range 2 weeks-14.1 years), 26.6% being ≤12 weeks of age (= early group). Median follow-up time was 2.8 years (7 months-5.8 years). 15 eyes (13.8%) developed glaucoma, 14 (48.3%) in the early group and 1 (1.3%) in the late group (p < 0.001). Within the early group, mean time for surgery differed significantly. Patients developing glaucoma had cataract surgery at 3.5 ± 1.1 weeks (mean ± SD) and the non-glaucoma patients at 5.7 ± 3.3 weeks (p = 0.024). In the entire cohort, 21 eyes (19.3%) had conditions associated with glaucoma; 57.1% of these developed glaucoma compared to 3.4% without these conditions (p < 0.001). Corrected distance visual acuity (CDVA) (decimal) of ≥0.5 was seen in 50 eyes (48.5%), median 0.63 in the late group and 0.15 in the early group. Glaucoma eyes in the early group (surgery at 3.5 weeks) achieved 0.56 median (range, 0.4-1.0) logMAR, (0.28 decimal) CDVA, whereas non-glaucoma eyes (surgery at 5.7 weeks) achieved 0.89 median (range 0.7-1.6) logMAR (0.13 decimal) CDVA; p = 0.016. Glaucoma development in infants between 5 weeks and 2 years of age was 6.7% (n = 2/30). CONCLUSIONS Comorbidity strongly increases the risk of secondary glaucoma. Surgery during the first month is correlated with better CDVA outcome and glaucoma. After 5 weeks of age, glaucoma rate is low with the BIL-IOL.

Abstract
PURPOSE To compare loteprednol etabonate (LE) gel 0.5% with prednisolone acetate suspension (PA) 1% for the treatment of inflammation after cataract surgery in children. SETTING Eleven sites in the United States. DESIGN Randomized, double-masked, parallel-group, noninferiority study. METHODS Eligible patients were aged 11 years or younger and candidates for routine, uncomplicated cataract surgery. Patients were randomized to a 4-week postsurgical regimen with LE gel 0.5% or PA 1%, twice on the day of surgery, 4 times daily for 2 weeks, twice daily for 1 week, and once daily for 1 week. Assessments included anterior chamber (AC) cells/flare, anterior chamber inflammation (ACI), synechiae, precipitates on the intraocular lens/cornea, visual acuity, and intraocular pressure. RESULTS The intent-to-treat population comprised 105 patients (LE gel, n = 53; PA 1%, n = 52) including 52 patients aged 3 years or younger. Patients achieved a similar mean ACI grade on postoperative day 14 (primary efficacy endpoint) whether treated with LE gel 0.5% or PA 1% (difference = 0.006, 2-sided 95% CI, -0.281 to 0.292). Similar ACI outcomes additionally were observed in patients aged 3 years or younger. LE gel 0.5% and PA 1% also appeared equally effective in resolving inflammation at all visits (days 7, 14, and 28 postsurgery), based on categorical distributions of ACI, AC cells, and AC flare scores/grades (P ≥ .06). Synechiae and corneal/IOL precipitates occurred infrequently with no significant differences between groups. No safety or tolerability concerns were identified, including no treatment-related IOP increases. CONCLUSIONS LE gel 0.5% was safe and effective in treating pediatric postcataract surgical inflammation, with similar outcomes as PA 1%.

Abstract
To analyze the visual acuity and complications between primary intraocular lens (IOL) implantation and contact lens wearing, this literature search was performed with data on patients with congenital cataract younger than 2 years published in March 2019. Seven identified studies enrolling 675 eyes were selected for analysis. Patients with primary IOL implantation owned better visual acuity than those with aphakia who wore the contact lens (weighted mean difference = 0.161; 95% CI, 0.108-0.214). For visual axis opacification (VAO), primary IOL implantation increases the incidence of VAO compared with contact lens wearing (relative risk = 0.23; 95% CI, 0.13-0.42). No statistically significant difference was found between the 2 groups about the prevalence of glaucoma and strabismus. Primary IOL implantation achieved better visual outcomes after cataract extraction in patients younger than 2 years. In addition, no higher risk for complications among primary IOL implantation compared with contact lens wearing was noted. Therefore, implanting a primary IOL during congenital cataract surgery is a better therapy for children younger than 2 years than wearing a contact lens.

Abstract
PURPOSE To report the rate and management of intra- and early postoperative complications of bag-in-the-lens intraocular lens (IOL) implantation technique for cataract treatment in paediatric patients of different age groups. SETTINGS Department of Ophthalmology, Justus-Liebig-University Giessen, University Hospital Giessen and Marburg GmbH, Campus Giessen, Giessen, Germany. DESIGN Retrospective non-randomized consecutive case series. METHODS Ninety eyes of 60 paediatric cataract patients were enrolled to this retrospective non-randomized observational consecutive case series single-centre study. All patients underwent cataract surgery with bag-in-the-lens IOL implantation between January 2008 and December 2018, performed by two experienced surgeons. The entire cohort was divided into four age groups: first - 0-<3 months, second - 3-<12 months, third - 12-<36 and fourth - >36 months-17 years of age. The intra- and postoperative complications were based on the clinical records. The description of management of complications related specifically to bag-in-the-lens IOL technique was based on the 39 consecutive cases operated since 1 Jan 2016 by one single surgeon that were all video documented. The early postoperative period was defined as 12 months after surgery. RESULTS Overall, there were 27 unilateral and 33 bilateral surgical cases of 24 female and 36 male children. The mean age at surgery was 45.25 months (range 1-200 months). The most common intraoperative events were vitreous prolapse and anterior capsule rupture with 28.9% and 13.3%, respectively. Within 12 months of follow-up, five eyes (5.6%) were re-operated because of visual axis reo-pacification (VAR). Intraocular hypertension was diagnosed in seven eyes (7.8%), including two cases that required surgical treatment. In all cases with intra- and early postoperative complications related specifically to bag-in-the-lens technique, it was possible to manage them and successfully implant bag-in-the-lens IOL. CONCLUSIONS Implementation of bag-in-the-lens technique in the treatment of paediatric cataract was associated with a relatively low rate of intra- and postoperative complications, including rare cases of VAR. The correct management of complications related specifically to bag-in-the-lens IOL implantation technique shall to be considered during the learning curve.

Abstract
OBJECTIVE To evaluate the morphology of iridocorneal angle and anterior segment in eyes of children with cataract. METHODS In this prospective cross-sectional study, we included eyes of children with bilateral cataract as well as unilateral cataract and fellow eyes. The iridocorneal angle was evaluated using gonioscopy. We compared the preoperative structures of iridocorneal angle and anterior segment between cataractous eyes and fellow eyes. The grading of iridocorneal angle and anatomical changes were analyzed. RESULTS We finally recruited 55 eyes of 55 children with bilateral cataract and 41 cataractous eyes and 33 fellow eyes of 41 children with unilateral cataract. The fellow eyes were used as a control group. The iridocorneal angle was open in eyes with pediatric cataract when compared to control eyes. The eyes with cataract exhibited more pigments on the trabecular meshwork than control eyes did (unilateral cataract vs. control, p = 0.013; bilateral cataract vs. control, p = 0.002). The eyes with cataract exhibited a smaller cornea than control eyes (unilateral cataract vs. control, p = 0.031; bilateral cataract vs. control, p < 0.001). CONCLUSIONS The iridocorneal angle is open in the eyes of children with cataract. Eyes with increased pigments on the trabecular meshwork need to be carefully monitored and surgeons should to be on the alert for postoperative glaucoma.

Abstract
Purpose: To determine the incidence, timing and risk factors for glaucoma and visual axis opacification development following surgery for congenital cataract in the first year of life. Methods: A prospective case series of all cataract surgery performed in Temple Street Children’s University Hospital over a 28-year period was conducted. A total of 93 subjects (135 eyes) were analysed. Sixty-two eyes had a primary intraocular lens inserted at the time of surgery; 73 eyes were aphakic. We recorded patient demographics, age at surgery, length of follow-up, rates and time to diagnosis of glaucoma and rates of visual axis opacification. Relative risk analysis was performed to identify potential risk factors for secondary glaucoma and visual axis opacification. Results: Mean length of follow-up was 160.02 ± 64.42 months (13.3 years), range 40–336 months. Final mean LogMAR across all groups was 0.85 ± 0.51 (0.90). Overall 45 (33.33%) eyes developed secondary glaucoma, 12 (19.4%) in pseudophakic eyes and 33 (45.21%) in aphakic eyes. The incidence of glaucoma was highest in bilateral aphakia (relative risk 1.96, p = 0.0240) and in eyes with corneal diameter <9.5 mm (relative risk 1.93, p = 0.0364). There was no significant difference in glaucoma rates between pseudophakia and aphakia in those operated on less than 2.5 months of age. Secondary glaucoma occurred between 3 months to 16.5 years post surgery. Rates of visual axis opacification were lower in aphakia compared to pseudophakia (relative risk 0.59, p = 0.0098). Conclusion: Overall glaucoma rates of one-third are similar to those recorded in the infantile aphakic treatment study. It can occur up to 17 years post cataract surgery, evidence that long-term follow-up is imperative.

Abstract
OBJECTIVE To study elevated postoperative intraocular pressure (PIOP) after paediatric cataract surgery in a reference centre and to compare the results obtained with the most relevant world literature. MATERIALS AND METHODS A retrospective observational study was conducted, collecting information from clinical records of 99 patients (142 eyes) operated on due to unilateral or bilateral paediatric cataracts between 2000 and 2008. RESULTS The proportion of eyes with PIOP≥20mmHg and bilateral cataracts was higher, 79.3%, than the proportion of eyes with PIOP≥20mmHg and a unilateral cataract, 20.7% (P=.032). The proportion of eyes with PIOP≥20mmHg between the eyes with cataract surgery before one month of age was higher, 50%, than between the eyes in which the cataract surgery was performed after one month of age, 17.2% (P=.009). PIOP values≥20mmHg were associated with a lower best corrected visual acuity at 5 years after cataract surgery (P=.020). The proportion of eyes with PIOP≥20mmHg and without intraocular lenses was higher, 69%, than the proportion of eyes with PIOP≥20mmHg and intraocular lenses, 31% (P<.001). CONCLUSIONS A PIOP>20mmHg was observed in 20.4% of eyes in a 5-year follow-up period, appearing more frequently in eyes with bilateral cataract than unilateral, and in aphakic eyes more than pseudophakic eyes. Elevation of the PIOP was associated with the performance of cataract surgery at early ages.

Abstract
Objective This meta-analysis aims to evaluate the incidence of secondary glaucoma in patients under the age of 2 years who underwent congenital cataract surgery with or without primary intraocular lens (IOL) implantation. Methods An electronic literature search was performed in Medline, EMBASE, and Web of Science databases to retrieve studies between January 2011 and November 2018. Patients with congenital cataract who did primary IOL implantation, aphakia, or secondary IOL implantation followed by receiving extraction surgery were included in this study. Relevant studies meeting defined eligibility criteria were selected and reviewed systematically by meta-analysis. Long-term incidences of secondary glaucoma, which developed at least one year after cataract surgery, were considered and discussed as clinical outcomes in each cohort. The pooled data were analyzed according to a random effects model. Results Eight publications involving 892 eyes were included in the current meta-analysis. In the general population of eyes with congenital cataract, the long-term incidence of secondary glaucoma was lower (P = 0.06) in eyes with primary IOL (9.5%) than in eyes without primary IOL (15.1%), including aphakia and secondary IOL. The pooled risk ratio (RR) favors primary IOL implantation in all patients (RR = 0.63). For bilateral congenital cataract, the incidence was 6.7% in eyes with primary IOL implantation, which is significantly lower than the 16.7% in eyes with aphakia and secondary IOL implantation (P<0.05, RR = 0.44). However, for unilateral congenital cataract surgery, the incidence was very similar in eyes with and without primary IOL (12.4% vs 12.0%, P = 0.61, RR = 0.87). Conclusions In patients under 2 years of age, primary IOL implantation for bilateral congenital cataract surgery is associated with a lower risk of secondary glaucoma.

Abstract
OBJECTIVE To evaluate the effect of intraocular lens (IOL) implantation on the development of secondary glaucoma after cataract surgery in pediatric patients. DESIGN Retrospective case series study. METHODS This study reviewed the medical records of children under 16 years of age who had undergone cataract surgery from 1996 to 2016 for congenital or developmental cataract. In every child an IOL was implanted in the primary surgery. Data collected included demographic information, age at cataract diagnosis and at surgery, surgical procedure, and postoperative follow-up of refraction, cup-to-disc ratio (C/D), intraocular pressure (IOP), and associated systemic and ocular anomalies. Patients with risk factors for glaucoma were excluded from the study. RESULTS Of the 255 children below age 16 years who underwent cataract extraction surgery with primary IOL implantation, 73 (124 eyes) met the inclusion criteria. Follow-up ranged from 4 to 18 years. Only 1 patient (0.8% of the 124 eyes) developed glaucoma in 1 of his 2 operated eyes; the surgeries were performed at 10 months, 1 week apart, and glaucoma was diagnosed 4 months later. One patient had suspected glaucoma in both eyes (incidence of 1.6%). Both these children were of Bedouin origin. CONCLUSION IOL implantation, by itself, is not a risk factor for development of secondary glaucoma after cataract surgery in a population below 16 years of age.

Abstract
PURPOSE Comparative evaluation of complications and visual outcomes following bilateral congenital cataract surgery in children up to 2 years of age with and without primary intraocular lens (IOL) implantation at 5 years follow-up. DESIGN Randomized controlled clinical trial. METHODS Sixty children (120 eyes) up to 2 years of age undergoing bilateral congenital cataract surgery were randomized to Group 1, primary aphakia (n = 30), or Group 2, primary IOL implantation (pseudophakia) (n = 30). A single surgeon performed surgeries with identical surgical technique. All patients were followed up regularly until 5 years postoperatively. At each follow-up, glaucoma, visual axis obscuration (VAO) requiring surgery, and inflammation (cell deposits, posterior synechiae) were assessed. Visual acuity was assessed until 5 years follow-up. The first operated eye was selected for statistical analysis. RESULTS Median age of the patients at time of surgery was 5.11 months (aphakia group) and 6.01 months (pseudophakia group) (P = .56). Five years postoperatively, incidence of glaucoma was 16% and 13.8% in Groups 1 and 2 (P = .82). Incidence of posterior synechiae was significantly higher in the pseudophakia group (27.6%) compared to the aphakia group (8%) (P = .004). VAO requiring surgery was seen in 8% and 10.3% of eyes in Groups 1 and 2 (P = .76). Mean logMAR visual acuity at 5 years follow-up was 0.59 ± 0.33 and 0.5 ± 0.23 in Groups 1 and 2, respectively (P = .79). However, more eyes in the pseudophakic group started giving documentable vision earlier in their postoperative follow-ups. CONCLUSIONS Incidence of postoperative complications was comparable between the groups, except for a higher incidence of posterior synechiae in pseudophakic eyes. Visual rehabilitation was faster in the pseudophakic group.

Abstract
PURPOSE To report outcome in a paediatric cohort with cataract extraction and implantation of bag-in-the-lens intraocular lens (BIL-IOL). METHODS Children younger than 16 years of age subjected to phacoemulsification with primary implantation of BIL-IOL during 2009 through 2013 were analysed retrospectively. Exclusion criteria were uveitis or ≤6 months of follow-up. RESULTS In total, 109 eyes of 84 children were included; 40 unilateral and 44 bilateral cataracts. For all eyes, median age at surgery was 2.5 years (range 2 weeks to 14.1 years) and 16 children (24 eyes) were ≤6 weeks. Coexisting systemic disease was more common in children with bilateral cataract (24 patients, 54.5%) compared to unilateral cataract (6 patients, 15.0%, p < 0.0001). Ocular comorbidity was more common in unilateral cataracts; n = 14 eyes (35.0%) compared to bilateral cataracts; n = 10 eyes (14.5%; p = 0.017). Median follow-up was 2.8 years (range 7 months to 5.8 years). During the follow-up period, 15 (13.8%) eyes developed glaucoma and five (4.6%) eyes required treatment for visual axis opacification (VAO). Corrected distance visual acuity (CDVA) for bilateral cataracts at last follow-up was 0.42 ± 0.45 (logMAR; mean±SD) with 35 (55.6%) eyes attaining a CDVA of ≥0.5 (dec). For unilateral cataracts mean CDVA was significantly poorer; 0.67 ± 0.51 (p = 0.010) with 15 (37.5%) eyes attaining a CDVA of ≥0.5. CONCLUSION For children having cataract surgery with primary implantation of BIL-IOL, VAO is rare and visual outcome overall good. Unilateral cataracts are associated with a higher proportion of ocular comorbidity and poorer visual outcome.

Abstract
Purpose To determine and to analyze the outcome of pediatric cataract surgery. Methods A retrospective chart review of individuals aged up to 10 years who underwent cataract surgery between January 1, 2004, and December 31, 2014, at the UniversityHospital Zurich, Switzerland. Results 63 children (94 affected eyes) with bilateral (68/94) or unilateral (26/94) cataract were identified. Surgery was performed at a median age of 1.5 months (IQR: 1.3–2.6 months) for the aphakic group (45/94) and of 50.7 months (IQR: 38.0–78.4 months) for the IOL group (49/94). At the last follow-up visit (median 31.1 months, IQR: 18.4–50.2 months), visual acuity was better in bilateral than in unilateral cataract cases. Posterior capsular opacification (PCO) was diagnosed in 30.9% of eyes without a significant difference in the IOL and aphakic groups (p = 0.12). Aphakic glaucoma was diagnosed in 12/45 eyes at a median of 6.8 months (IQR 2.1–13.3 months) after surgery. Microcornea (5/12) and anterior segment anomalies (8/12) were associated with glaucoma development (p < 0.05). Conclusion Laterality and timing of surgery influence the outcome of pediatric cataract surgery. PCO was the most frequent postoperative complication. Aphakic glaucoma is often associated with ocular developmental abnormalities and a poor visual outcome.

Abstract
INTRODUCTION Pediatric cataracts are a huge problem worldwide, and with improving techniques and technology, the surgical treatment and postoperative visual rehabilitation are improving. Despite intraocular lenses(IOLs) being the standard of care for adult cataract surgery, this issue is still somewhat controversial, particularly in young children and infants due to lack of unequivocal evidence. This review therefore summarises the findings from recent studies on the aspect of IOL implantation in pediatric eyes. Areas covered: An extensive literature search was undertaken for published articles on congenital/developmental pediatric cataracts, and IOL implantation, where literature pertinent to traumatic and subluxated cataracts was not included in the review. Pubmed was used for literature search, and keywords entered were : pediatric, cataract surgery, intraocular lens, persistent fetal vasculature, outcomes, complications, visual performance with intraocular lenses. Expert commentary: Recent literature supports IOL implantation in most cases of congenital / developmental pediatric cataracts, and it seems like the way forward. However, the jury is still out on IOL implantation in infants, particularly in bilateral cataracts. Thus, surgeons must be extremely cautious in planning primary IOL implantation in infant eyes, and if they do perform IOL implantation, rigorous followup is mandatory.

Abstract
Purpose: To evaluate the long-term visual outcomes and complications of the piggyback intraocular lens (IOL) implantation compared to aphakia for infantile cataract. Patients and Methods: In a comparative study from 1998 to 2007, piggyback IOL implantation (piggyback IOL group) was performed for 14 infants (23 eyes) with infantile cataract and 20 infants (32 eyes) who were aphakic (aphakia group) after infantile cataract surgery. Data were collected on logMAR visual acuity, and postoperative complications over a mean follow-up time of 6.2 ± 1.7 years and 5.8 ± 1.7 years. Results: The mean age at surgery was 7.5 ± 0.6 months and 6.0 ± 3.3 months for the piggyback and the aphakic group respectively (P > 0.05). At the last follow-up visit, visual acuity was 0.85 ± 0.73 (median = 0.70, interquartile range = 0.3–1.32) in the piggyback IOL group and 0.89 ± 0.56 (median = 0.86, interquartile range = 0.50–1.24) in the aphakic group (P > 0.05). There was a positive relationship between age and visual outcomes in the aphakic group (r = 0.4, P = 0.04) but not in the piggyback IOL group (P = 0.48). There was no significant difference between the mean myopic shift in the piggyback IOL group (∑5.28 ± 1.06 D) and the aphakic group (∑5.10 ± 1.02 D) (P > 0.05). The incidence of reoperation due to complications in piggyback IOL group was higher than aphakic group (%48 vs. %16, respectively, P ≤ 0.01). However, in patients older than 6 months, this risk was not significantly different compared to the aphakic group. Conclusions: Although piggyback IOL implantation for infantile cataract is optically acceptable as a treatment option, there is no significant difference in visual outcomes compared to aphakia. The incidence in reoperation due to complications in patients aged 6 months or younger is higher than those treated with aphakia.

Abstract
PURPOSE To retrospectively analyze the surgical outcomes of congenital/developmental cataracts in Japan. METHODS A mail questionnaire was sent to facilities engaged in surgical treatment of congenital cataracts. RESULTS Twenty-nine facilities reported on 809 eyes of 508 patients with congenital/developmental cataracts. Three hundred fifty-nine eyes underwent intraocular lens implantation (pseudophakia group), while 450 eyes were left aphakic (aphakia group). The average age at surgery was significantly higher in the pseudophakia group (70 ± 53 months) than in the aphakia group (14 ± 24 months) (P < 0.0001). A significantly larger proportion of patients with unilateral cataract (52.0 %) received IOL implantation than did those with bilateral cataracts (42.6 %) (P = 0.0224). The prevalence of associated ocular disorders, such as nystagmus, microcornea, nanophthalmos, and persistent fetal vasculature, was significantly higher in the aphakia group than in the pseudophakia group. Postoperatively, glaucoma developed more frequently in the aphakia group (5.8 %) than in the pseudophakia group (0.7 %) (P = 0.0003). Posterior capsule opacification developed more frequently in the pseudophakic eyes even when both posterior capsulotomy and anterior vitrectomy were performed, especially in patients aged 1 year or younger. Postoperative visual acuity was significantly better in the pseudophakia group than in the aphakia group, both in the unilateral and in the bilateral cases. CONCLUSIONS Surgeons tended to select IOL implantation, rather than to leave the eye aphakic, in patients who were older at the time of surgery, had fewer coexisting ocular disorders, and suffered from unilateral cataract. Under such circumstances, pseudophakic eyes obtained significantly better postoperative visual acuity than did aphakic eyes.

Abstract
IMPORTANCE Glaucoma-related adverse events constitute major sight-threatening complications of cataract removal in infancy, yet their relationship to aphakia vs primary intraocular lens (IOL) implantation remains unsettled. OBJECTIVE To identify and characterize cases of glaucoma and glaucoma-related adverse events (glaucoma + glaucoma suspect) among children in the Infant Aphakia Treatment Study by the age of 5 years. DESIGN, SETTING, AND PARTICIPANTS A multicenter randomized clinical trial of 114 infants with unilateral congenital cataract in referral centers who were between ages 1 and 6 months at surgery. Mean follow-up was 4.8 years. This secondary analysis was conducted from December 23, 2004, to November 13, 2013. INTERVENTIONS Participants were randomized at cataract surgery to either primary IOL or no IOL implantation (contact lens). Standardized definitions of glaucoma and glaucoma suspect were created for the Infant Aphakia Treatment Study and applied for surveillance and diagnosis. MAIN OUTCOMES AND MEASURES Development of glaucoma and glaucoma + glaucoma suspect in operated on eyes for children up to age 5 years, plus intraocular pressure, visual acuity, and axial length at age 5 years. RESULTS Product limit estimates of the risk for glaucoma and glaucoma + glaucoma suspect at 4.8 years after surgery were 17% (95% CI, 11%-25%) and 31% (95% CI, 24%-41%), respectively. The contact lens and IOL groups were not significantly different for either outcome: glaucoma (hazard ratio [HR], 0.8; 95% CI, 0.3-2.0; P = .62) and glaucoma + glaucoma suspect (HR, 1.3; 95% CI, 0.6-2.5; P = .58). Younger (vs older) age at surgery conferred an increased risk for glaucoma (26% vs 9%, respectively) at 4.8 years after surgery (HR, 3.2; 95% CI, 1.2-8.3), and smaller (vs larger) corneal diameter showed an increased risk for glaucoma + glaucoma suspect (HR, 2.5; 95% CI, 1.3-5.0). Age and corneal diameter were significantly positively correlated. Glaucoma was predominantly open angle (19 of 20 cases, 95%), most eyes received medication (19 of 20, 95%), and 8 of 20 eyes (40%) underwent surgery. CONCLUSIONS AND RELEVANCE These results suggest that glaucoma-related adverse events are common and increase between ages 1 and 5 years in infants after unilateral cataract removal at 1 to 6 months of age; primary IOL placement does not mitigate their risk but surgery at a younger age increases the risk. Longer follow-up of these children may further characterize risk factors, long-term outcomes, potential differences between eyes having primary IOL vs aphakia, and optimal timing of unilateral congenital cataract removal.

Abstract
PURPOSE The purpose of this study was to look at the visual outcomes of bilateral congenital cataract surgery. DESIGN A prospective study was conducted. METHODS A total of 102 eyes of 51 children aged between 2 and 12 months undergoing bilateral congenital cataract surgery from January 2008 to December 2008 with a 3-year follow-up were included in this study. The study was performed at a tertiary public hospital. Data were analyzed using SPSS version 17. Chi-square (χ²) tests were performed to identify the association between visual outcome and age at surgery. P values less than 0.05 were considered statistically significant. RESULTS Among the 102 eyes, 32 (31.4%) eyes were operated on when the subjects were aged between 2 and 3 months, and 70 (68.6%) eyes were operated on at the age of 3 to 12 months. The subjects were followed up for 3 years after surgery. Postoperative best-corrected visual acuity was measured. Visual outcomes were significantly poor in children aged 3 months or older (P < 0.001) as compared with children aged between 2 and 3 months. CONCLUSIONS Early detection and treatment with long-term postoperative rehabilitation is vital to improve visual outcomes of children with congenital cataract.

Abstract
PURPOSE Cataract surgery in young children poses different challenges and potential complications compared to those encountered in adult populations. We performed a literature review of the complications of pediatric cataract surgery. METHODS Literature review of complications of pediatric cataract surgery. RESULTS Complications in children vary based on the age of the patient at surgery and the cause of the cataract. Common events discussed include increased inflammatory response, opacification of the posterior capsule, lens reproliferation, pupillary membrane, and amblyopia; less common events include infections, significant bleeding, and retinal detachment. CONCLUSION Complications after cataract surgery in children are often associated with a robust inflammatory reaction or secondary opacity and, in infants, glaucoma. Late complications can occur decades later, so that long-term follow-up is required. Though surgery carries significant risks, the consequences of no surgery and irreversible deprivation amblyopia in very young children should be considered.

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 compare primary intra-ocular lens (IOL) implantation with use of press-on spherical lens for aphakia correction following unilateral infantile cataract removal. METHODS Sixty infants with a unilateral cataract underwent cataract surgery and were randomly assigned to the IOL (A group) or no IOL group (B group). Residual refractive error was corrected with spectacles in the A group and a press-on spherical lens was used to treat aphakia in the B group. Grating visual acuity (VA) was measured and patients were followed for up to 1 year. RESULTS LogMAR VA in the operated eyes of both groups was significantly better 1 year than 1 month after surgery. Mean logMAR VA difference between 1 year and 1 month after surgery was higher in the A group (0.457 ± 0.110) than in the B group (0.323 ± 0.114, p < 0.0001). Serious inflammation occurred significantly more often in the A group than in the B group (p = 0.007). Visual axis opacity occurred more often in the A group than in the B group (pupillary membrane: A: six eyes, 20%, B: none, p = 0.024; lens reproliferation: A: 10 eyes, 33%, B: two eyes, 7%, p = 0.021). Glaucoma occurred equally in both groups (p = 0.612). No other complications occurred. CONCLUSIONS Primary IOL implantation appears to be a relatively safe, effective optical correction strategy following unilateral cataract extraction in this age group. Patients for whom an IOL is not suitable can be treated with a press-on spherical lens for optical correction.

Abstract
PURPOSE To evaluate complication rates following implantation of hydrophobic acrylic versus polymethyl methacrylate (PMMA) intraocular lens (IOL) with cataract surgery in infants. METHODS Records of children undergoing cataract surgery with IOL implantation in first year of life were retrospectively reviewed. Infants were divided into two groups--hydrophobic acrylic IOLs were implanted in group A, and PMMA IOLs in group B. Outcome measures included incidence of complications, additional surgical procedures, and refractive error changes. RESULTS One hundred and thirteen eyes of 113 children (75 males) with mean age of 6.49 ± 3.56 months were included. Group A included 62 eyes, and group B included 51 eyes. The two groups did not differ significantly in terms of age and axial length. There was no significant difference between the groups for incidence of posterior capsular opacification (PCO), pupillary membranes, glaucoma, fibrin on IOL surface or IOL malposition (p = 0.09). Development of PCO was delayed in group A (p = 0.049). Thirteen eyes of group A and 18 eyes of group B required additional surgical intervention (p = 0.20) in the follow-up visits. CONCLUSION Comparable complications may be expected in infants with PMMA and hydrophobic acrylic lenses. Children implanted with PMMA IOLs may require earlier surgical re-intervention for PCO.

Abstract
AIM To determine the incidence and predictors of glaucoma following surgery for congenital and infantile cataract in an Australian population. DESIGN Retrospective cohort study. PARTICIPANTS Infants (<12 months) having had lens extraction between January 1992 and May 2006, from two tertiary referral centres. METHODS Children with uveitis, anterior segment dysgenesis, aniridia, retinopathy of prematurity, and lens subluxation were excluded. Potential predictors of incident glaucoma were examined using Cox proportional hazards regression with adjustment for clustering between eyes. MAIN OUTCOME MEASURES Incidence and predictors of secondary glaucoma. RESULTS One hundred and forty-seven eyes of 101 patients (46 bilateral cataract; 55 unilateral cataract) were included, with median follow-up of 9.9 years (range 1.2-18.9 years). Cumulative incidence of glaucoma was 32.0% for eyes (n = 47) and 30.7% (n = 31) for subjects. Incidence was higher in children with bilateral cataract (38.9 vs. 17.1%, p = 0.004). There were 3.9 cases of glaucoma per 100 person years of follow-up, the incidence rate being highest for surgery performed in the first month of life. Children with glaucoma had longer median follow-up (11.8 vs. 9.3 years, p = 0.005). Risk of glaucoma decreased with increasing months of age at operation: hazard ratio 0.79, 95% confidence interval 0.69-0.91, p = 0.001. Median visual acuity was worse in children with unilateral cataract (p < 0.001). CONCLUSIONS We identified an increased risk of glaucoma when cataract surgery was performed in younger infants, and in those with bilateral cataract. As glaucoma may develop over a decade following lens extraction, life-long surveillance is needed to prevent glaucoma-associated vision loss.

Abstract
The greatest concern in children with cataracts is irreversible visual loss. The timing of congenital cataract surgery is critical for the visual rehabilitation. Cataract surgery in children remains complex and challenging. The incidence of complications during or after operation is higher in children than adults. Some complications could be avoided by meticulous attention to surgical technique and postoperative care, and others were caused by more exuberant inflammatory response associated with surgery on an immature eye or the intrinsic eyes abnormalities. Utilizing of advanced techniques and timely applying topical corticosteroids and cycloplegic agents can reduce the occurrence of visual axis opacification. Operation on children with strabismus or nystagmus, and applying occlusion therapy on amblyopic eyes can balance the visual inputs to the two eyes. Diagnosis of glaucoma following congenital cataract surgery requires lifelong surveillance and continuous assessment of the problem. So cataract surgeries in children are not the end of journey, but one step on the long road to visual rehabilitation. This paper describes recent evidence from the literature regarding the advance of management after congenital cataract surgery.

Abstract
Modern surgical techniques allow congenital cataract surgery to be performed much more successfully. The development of a secondary glaucoma is the most dreaded postoperative complication (one third of all pediatric secondary glaucomas). Due to the limited value of the available literature, data on prevalence are unreliable. A 10-year postoperative incidence of 10-25% is given in the literature for developing secondary glaucoma and the frequency increases with the duration of follow-up. A major risk factor seems to be the age at the time of surgery. The younger the patient is at the time of surgery the higher the risk of secondary glaucoma. A microcornea seems to be another risk factor in multivariate analysis. The following postoperative changes might be involved in the pathogenesis: peripheral anterior synechia, high iris insertion and membranous material over the trabecular meshwork. Additionally postoperative inflammation, reaction to lens epithelial cells, perioperative barotrauma and loss of anterior segment architecture might also be responsible. In order to evaluate the optimal age window for congenital cataract surgery and risk factors for the development of secondary glaucoma, a prospective longitudinal study is mandatory.

Abstract
PURPOSE To evaluate the long-term visual outcome after early surgery of bilateral dense congenital cataracts, aphakic correction with glasses and secondary intraocular lens (IOL) implantation around 2 years of age. METHODS The medical records of paediatric patients who underwent cataract extraction, aphakic correction and secondary IOL implantation from 1993 to 2004 at Seoul National University Children's Hospital were reviewed retrospectively. Age at secondary IOL implantation, axial length (AL), best corrected visual acuity (BCVA), refractive error, ocular alignment, stereopsis, and postoperative ocular complications were recorded. RESULTS Thirty-seven paediatric bilateral pseudophakic patients were identified with a mean follow-up period of 81.4 months. Best corrected visual acuity of 20/40 or better were attained in 44.0% of eyes, and the median BCVA was 20/50. Preoperative factors associated with poor visual prognosis included cataract surgery after 8 weeks of age, interocular AL difference of 0.5 mm or more, and glaucoma. Amblyopic eyes showed more myopic change compared to fellow eyes. Good or moderate binocular function was achieved in 18.9% of all patients. Incidences of strabismus, glaucoma, posterior capsular opacity formation were 46.0%, 32.4% and 4.0%, respectively. CONCLUSION Good postoperative BCVA and binocular function were achieved in most healthy children with bilateral dense congenital cataract and no posterior segment pathology. Early cataract surgery, aphakic correction with glasses and secondary IOL implantation around 2 years of age appears to be appropriate methods.

Abstract
OBJECTIVE To report the incidence of aphakic glaucoma following lensectomy in infants in their first year of life and examine the impact of this diagnosis on visual outcome. DESIGN Retrospective cohort study. PARTICIPANTS All patients who had lensectomy for congenital cataract during the first year of life at British Columbia Children's Hospital between 1995 and 2006. METHODS Retrospective review of medical records. RESULTS Seventy-five eyes of 46 patients (29 bilateral, 17 unilateral) were included. The mean age at lensectomy was 93 days (range, 2-364 days) with a mean follow-up of 77.5 months (range, 36-166 months). Patients with bilateral cataracts had a better visual outcome than those with unilateral cataracts (p < 0.032). Of the patients with measurable visual acuity (VA), 34 of 45 eyes (75.6%) with bilateral cataracts and only 3 of 16 eyes (18.8%) with unilateral cataract achieved a VA of 20/40 or better. Eighteen of 75 eyes (24%) developed aphakic glaucoma at a mean of 30 months following lensectomy. Nine patients (50%) achieved final vision of 20/40 or better. The development of aphakic glaucoma was not associated with worse visual outcomes (p < 0.315). The mean intraocular pressure (IOP) at diagnosis was 28.6±5.9 mm Hg and mean final IOP was 14.1 ± 3.0 mm Hg, a significant reduction (p < 0.0001). Fifteen of 18 eyes with aphakic glaucoma (83.3%) required surgical intervention to achieve IOP control. CONCLUSIONS Children with aphakic glaucoma may have good visual outcomes if it is recognized early and managed appropriately. A significant proportion of patients required surgical intervention to control IOP.

Axial growth and binocular function following bilateral lensectomy and scleral fixation of an intraocular lens in nontraumatic ectopia lentis. Jpn J Ophthalmol 2010; 54:232-8. [PMID: 20577858 DOI: 10.1007/s10384-009-0797-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2009] [Accepted: 12/21/2009] [Indexed: 10/19/2022]
Abstract
PURPOSE To evaluate binocular function (BF) and changes in axial length (AL) bilaterally in pseudophakic eyes of children after lensectomy and scleral fixation of an intraocular lens (IOL) for nontraumatic ectopia lentis. METHODS In 15 children who had undergone bilateral lensectomy and scleral fixation of an IOL for nontraumatic ectopia lentis, AL was measured preoperatively and at last follow-up, and BF was assessed at last follow-up. Axial growth was compared with the expected and observed patterns of normal eyes, and the results were compared between patients with isolated ectopia lentis and those with Marfan syndrome. RESULTS Ten of the 15 patients had Marfan syndrome. Mean age at surgery was 5.2 +/- 2.4 years; mean follow-up was 51.7 +/- 29.2 months. A mean axial growth rate of 0.39 mm/year during 51.7 postoperative months was greater than the expected (0.07 mm/year) or the observed (0.09-0.24 mm/year) rates in age-matched normal eyes. The axial growth rates in isolated ectopia lentis patients and Marfan patients were not significantly different (P = 0.159). Binocular fusion and stereoacuity of < or =800 seconds of arc were achieved by nine patients, and worse or no BF was achieved by the remaining six patients. These six patients were significantly more likely to have pre- or postoperative anisometropia of > or =3.0 D (66.6%) than the other nine patients (0%). CONCLUSIONS Because of greater than normal axial growth, more undercorrection of the IOL power is required than is usual in bilateral surgery for nontraumatic ectopia lentis. Good or moderate levels of postoperative BF were achieved in more than half of patients.
