Nihalani BR, VanderVeen DK. Timing of Diagnosis and Treatment of Glaucoma following Infantile Cataract Surgery. Ophthalmol Glaucoma 2024; 7:290-297. [PMID: 38104771 DOI: 10.1016/j.ogla.2023.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 11/12/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
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
Importance The p.Asp67Tyr genetic variant in the GJA3 gene is responsible for congenital cataracts in a family with a high incidence of glaucoma following cataract surgery. Objective To describe the clinical features of a family with a strong association between congenital cataracts and glaucoma following cataract surgery secondary to a genetic variant in the GJA3 gene (NM_021954.4:c.199G>T, p.Asp67Tyr). Design, Setting, and Participants This was a retrospective, observational, case series, genetic association study from the University of Iowa spanning 61 years. Examined were the ophthalmic records from 1961 through 2022 of the family members of a 4-generation pedigree with autosomal dominant congenital cataracts. Main Outcomes and Measures Frequency of glaucoma following cataract surgery and postoperative complications among family members with congenital cataract due to the p.Asp67Tyr GJA3 genetic variant. Results Medical records were available from 11 of 12 family members (7 male [63.6%]) with congenital cataract with a mean (SD) follow-up of 30 (21.7) years (range, 0.2-61 years). Eight of 9 patients with congenital cataracts developed glaucoma, and 8 of 8 patients who had cataract surgery at age 2 years or younger developed glaucoma following cataract surgery. The only family member with congenital cataracts who did not develop glaucoma had delayed cataract surgery until 12 and 21 years of age. Five of 11 family members (45.5%) had retinal detachments after cataract extraction and vitrectomy. No patients developed retinal detachments after prophylactic 360-degree endolaser. Conclusions and Relevance The GJA3 genetic variant, p.Asp67Tyr, was identified in a 4-generation congenital cataract pedigree from Iowa. This report suggests that patients with congenital cataract due to some GJA3 genetic variants may be at especially high risk for glaucoma following cataract surgery. Retinal detachments after cataract extraction in the first 2 years of life were also common in this family, and prophylactic retinal endolaser may be indicated at the time of surgery.

Abstract
PURPOSE To assess long-time results of primary surgical treatment in children with glaucoma after congenital cataract surgery. METHODS A retrospective study of 37 eyes from 35 children with glaucoma after congenital cataract surgery, who underwent surgery between 2011 and 2021 at the Childhood Glaucoma Center, University Medical Center Mainz, Germany. Only children, who received a primary glaucoma surgery in our clinic within the given time (n = 25) and had at least one-year follow-up (n = 21), were included in the further analysis. The mean follow-up time was 40.4±35.1 months. The primary outcome was the mean reduction in IOP (in mmHg) from baseline to follow-up visits after the surgery, measured with Perkins tonometry. RESULTS 8 patients (38%) were treated with probe trabeculotomy (probe TO), 6 (29%) with 360° catheter-assisted trabeculotomy (360° TO) and 7 (33%) with cyclodestructive procedures. IOP was significantly reduced after probe TO and 360° TO after 2 years, from 26.9 mmHg to 17.4 mmHg (p<0.01) and 25.2 mmHg to 14.1 mmHg (p<0.02), respectively. There was no significant IOP reduction after cyclodestructive procedures after 2 years. Both, probe TO and 360° TO led descriptively to eye drops reduction after 2 years, from 2.0 to 0.7 and 3.2 to 1.1. The reduction was not significant. CONCLUSIONS In glaucoma after congenital cataract surgery, both trabeculotomy techniques, lead to good reduction of IOP after 2 years. There is a need for a prospective study with comparison to the use of glaucoma drainage implants.

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
PURPOSE To compare outcomes of 2 surgical techniques in children undergoing cataract surgery with intraocular lens (IOL) implantation: optic capture of IOL without anterior vitrectomy (AV) or in-the-bag IOL with AV. DESIGN Prospective randomized controlled trial. METHODS Patients were randomized to 2 groups: optic capture without AV (group 1) or in-the-bag implantation with AV (group 2). The following variables were compared: visual axis opacification (VAO), inflammatory deposits on IOL surface, anteroposterior synechia, IOL tilt and decentration, lenticular astigmatism, refractive prediction error, and posterior segment complications. RESULTS Fifty-one eyes of 37 children were investigated with a mean follow-up of 20.1±8.5 months. Group 1 and group 2 had mean ages of 59.2±32.6 and 46.5±21.9 months, respectively (P = .104). Three eyes in group 1 and 2 eyes in group 2 developed VAO (P = .656). Two eyes in group 1 and 5 eyes in group 2 developed anteroposterior synechia (P = .291). Six eyes in group 1 and 11 eyes in group 2 had inflammatory deposits on the IOL (P = .233). Both groups had similar IOL tilt and decentralization (for all meridians, P > .05). The absolute refractive prediction error was 0.55±0.34 diopter (D) and 0.53±0.3 D, respectively (P = .294). Each group had 1 eye with intraocular hypertension (P = .932). CONCLUSION The optic capture method was similar to the conventional technique in the quantitative evaluation of comprehensive data such as visual axis opacification, inflammatory sequelae, refractive outcomes, and IOL stability. The optic capture technique is an appealing option for pediatric cataract surgery because it eliminates the requirement for vitrectomy.

Abstract
PURPOSE To review information pertaining to secondary glaucoma following infant lensectomy and provide evidence to support the mechanism responsible for this condition. METHODS Reported risk factors and proposed mechanisms for infantile aphakic glaucoma are reviewed. Laboratory studies and clinical observations in affected patients with glaucoma are described. Evidence of postoperative anterior chamber fibrosis is reviewed and interpreted. RESULTS Clinical evidence demonstrated the development of anterior chamber fibrosis following infant cataract surgery. Laboratory studies showed liberated lens epithelial cell transition to fibroblasts. CONCLUSIONS The review and assessment of laboratory and clinical evidence support the proposal that infantile aphakic glaucoma is caused, in part, by postoperative anterior chamber fibroization related to lens cell dispersion, cytokine activation, and epithelial-mesenchymal transition with resultant filtration angle fibrosis and secondary loss of filtration function.

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
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.

Abstract
Importance Glaucoma-related adverse events constitute serious complications of cataract removal in infancy, yet long-term data on incidence and visual outcome remain lacking. Objective To identify and characterize incident cases of glaucoma and glaucoma-related adverse events (glaucoma + glaucoma suspect) among children in the Infant Aphakia Treatment Study (IATS) by the age of 10.5 years and to determine whether these diagnoses are associated with optic nerve head (ONH) and peripapillary retinal nerve fiber layer (RNFL) assessment. Design, Setting, and Participants Analysis of a multicenter randomized clinical trial of 114 infants with unilateral congenital cataract who were aged 1 to 6 months at surgery. Data on long-term glaucoma-related status and outcomes were collected when children were 10.5 years old (July 14, 2015, to July 12, 2019) and analyzed from March 30, 2019, to August 6, 2019. Interventions Participants were randomized at cataract surgery to either primary intraocular lens (IOL), or aphakia (contact lens [CL]). Standardized definitions of glaucoma and glaucoma suspect were created for IATS and applied for surveillance and diagnosis. Main Outcomes and Measures Development of glaucoma and glaucoma + glaucoma suspect in operated-on eyes up to age 10.5 years, plus intraocular pressure, axial length, RNFL (by optical coherence tomography), and ONH photographs. Results In Kaplan-Meier analysis, for all study eyes combined (n = 114), risk of glaucoma after cataract removal rose from 9% (95% CI, 5%-16%) at 1 year, to 17% (95% CI, 11%-25%) at 5 years, to 22% (95% CI, 16%-31%) at 10 years. The risk of glaucoma plus glaucoma suspect diagnosis after cataract removal rose from 12% (95% CI, 7%-20%) at 1 year, to 31% (95% CI, 24%-41%) at 5 years, to 40% (95% CI, 32%-50%) at 10 years. Risk of glaucoma and glaucoma plus glaucoma suspect diagnosis at 10 years was not significantly different between treatment groups. Eyes with glaucoma (compared with eyes with glaucoma suspect or neither) had longer axial length but relatively preserved RNFL and similar ONH appearance and visual acuity at age 10 years. Conclusions and Relevance Risk of glaucoma-related adverse events continues to increase with longer follow-up of children following unilateral cataract removal in infancy and is not associated with primary IOL implantation. Development of glaucoma (or glaucoma suspect) after removal of unilateral congenital cataract was not associated with worse visual acuity outcomes at 10 years. Trial Registration ClinicalTrials.gov Identifier: NCT00212134.

PURPOSE To assess the intraocular pressure and visual acuity before and after pediatric congenital cataract surgery performed at a relatively older age. METHODS A retrospective analysis of all consecutive pediatric patients diagnosed and operated for bilateral congenital cataracts during a seven-year period (2012-2018) in rural southern Ethiopia. Non-ambulatory vision was defined as hand motion or worse. The main outcome measures were intraocular pressure (IOP) and visual acuity. RESULTS Thirty-two children were included, 17 females (53.1%), with a mean age of 11 years (± 2.83) [range, 7-18]. A total of 59 eyes were operated on. The mean follow-up was 4.8 ± 1.8 years (range, 2-8). VA improved from 20/1400 preoperatively to 20/440 postoperatively OD and 20/540 OS (p < 0.001). More eyes had ambulatory vision after cataract surgery than pre-surgery (56 eyes [95%] vs. 29 eyes [49%], p < 0.001). The IOP decreased from a mean preoperative value of 18.4 ± 7.1 mmHg to 14.5 ± 2.9 postoperatively OD (p < 0.001) and 16.3 ± 5.9 mmHg to 13.9 ± 3.5 OS (p < 0.001). Fifteen eyes (24%) had increased IOP (> 21 mmHg) preoperatively, of which three remained high after surgery. Positive correlations were found between IOP, axial length and cup-to-disc ratio. None of the patients required pressure-lowering procedures. CONCLUSION Bilateral congenital cataracts may be associated with ocular hypertension, with possible progression to glaucoma if left untreated. Surgery at a relatively older age often was associated with a significant improvement in intraocular pressure and ambulatory vision.

Abstract
PURPOSE To analyze clinical characteristics, treatment, and long-term outcomes of pediatric patients with glaucoma after congenital cataract surgery at a single tertiary care hospital. METHODS Medical records of pediatric patients diagnosed as having glaucoma secondary to congenital cataract surgery between 1996 and 2016 were reviewed retrospectively. RESULTS A total of 58 eyes of 42 patients were included with a median follow-up time of 55 months (interquartile range [IQR]: 27 to 128) after glaucoma diagnosis. Mean time of glaucoma onset after cataract surgery was 35 months (IQR: 5 to 96). At diagnosis, 81% of the eyes were aphakic and the majority presented with an open angle (86%). Multivariate analysis demonstrated that glaucoma diagnosis was made earlier in eyes with persistent fetal vasculature (β = -0.334, P = .006) and aphakic eyes (β = 0.404, P = .001). Two-thirds of eyes required surgical treatment for glaucoma. Seventy percent had an Ahmed glaucoma valve (New World Medical, Inc) implantation as their primary procedure, followed by trabeculectomy (24%) and synechiolysis with peripheral iridotomy (6%). All medically treated eyes and 78% of the surgically treated eyes achieved intraocular pressure (IOP) control at the final visit. CONCLUSIONS Diagnosis of glaucoma after congenital cataract surgery seems to follow a bimodal distribution (years 1 and 5 after cataract surgery). Two-thirds of the eyes required surgical hypotensive treatment to achieve IOP control. Ahmed glaucoma valve implantation is a safe and effective surgical option to be considered as both first- and second-line treatment. Functional outcome was more favorable in those eyes with medically controlled glaucoma. [J Pediatr Ophthalmol Strabismus. 2020;57(5):292-300.].

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

Abstract
PURPOSE To compare complications in children up to 4 years old having cataract surgery with intraocular lens (IOL) implantation using 2 techniques: in-the-bag IOL with anterior vitrectomy or optic capture of IOL with no anterior vitrectomy. SETTING Iladevi Cataract & IOL Research Centre, Ahmedabad, India. DESIGN Prospective randomized control clinical trial. METHODS The study included children having cataract surgery with IOL implantation. Patients were randomized to Group 1 (in-the-bag 3-piece hydrophobic acrylic IOL [Acrysof MA60AC] with anterior vitrectomy) or Group 2 (optic capture of the same IOL without anterior vitrectomy). Intraoperative complications were documented. Postoperative visual axis obscuration (VAO), glaucoma, cell deposits on the IOL, and posterior synechiae were compared at 1, 3, 6, and 12 months. RESULTS The study comprised 61 children (61 eyes). The mean ages were 14.8 months ±11.47 (SD) in Group 1 (n = 30) and 18.2 ± 11.47 months in Group 2 (n = 31). Overall, only 1 eye in Group 1 developed a VAO requiring membranectomy 4 months postoperatively, and 2 eyes in Group 1 developed glaucoma over 12 months (P = .49). Intraocular lens cell deposits and posterior synechiae were comparable between groups. The IOL could not be captured in 5 eyes (16.1%); no complications occurred in these eyes. CONCLUSIONS Optic capture of 3-piece hydrophobic acrylic IOLs could be achieved in most eyes. The VAO, glaucoma, and inflammation were comparable 12 months postoperatively. Thus, optic capture of an IOL is an alternative surgical technique that can be used to avoid vitrectomy, even in children younger than 4 years.

Abstract
PURPOSE To evaluate the long-term incidence and risk of glaucoma after bilateral congenital cataract surgery in microphthalmic eyes. DESIGN Retrospective, observational case series. METHODS Subjects: Children with microphthalmic eyes who had undergone surgery for bilateral congenital cataract within 6 months of birth and been followed up for at least 5 years. PROCEDURES Review of medical records at our institution. MAIN OUTCOME MEASURES Probability of an eye's developing glaucoma after bilateral congenital cataract surgery and associated risk factors. RESULTS Thirty-eight eyes of 19 children with bilateral congenital cataract were included. The mean age at surgery was 3.2 ± 1.7 months, and the mean follow-up duration was 7.79 ± 2.61 years. After cataract surgery, 11 eyes (29.0%) developed glaucoma at the age of 4.0 ± 1.4 years. Three of these eyes underwent Ahmed glaucoma valve implantation surgery. The probability of an eye's developing glaucoma was estimated to be 32.0% by 10 years after surgery. In a multivariate analysis, axial length was significantly associated with glaucoma development (odds ratio = 0.364, P = .025). Age at the time of cataract surgery, corneal diameter, and aphakia did not affect the risk of glaucoma (P > .10). Eyes without glaucoma had a better final visual outcome than those with glaucoma (0.75 ± 0.60 and 1.47 ± 1.10 logMAR, respectively, P = .049). CONCLUSIONS The long-term cumulative risk of postoperative glaucoma development was 32.0% by 10 years after bilateral congenital cataract surgery. Because the risk of developing glaucoma persists for several years after surgery, careful monitoring and control of intraocular pressure is needed to preserve vision in such patients.

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
BackgroundWe investigated glaucoma related adverse events, predictors and impact at 5 years following surgery in the IoLunder2 cohortMethodsPopulation based observational cohort study of children undergoing cataract surgery aged 2 years or under between January 2009 and December 2010. Glaucoma was defined using internationally accepted taxonomies based on the consequences of elevated intraocular pressure (IOP). Glaucoma related adverse events were any involving elevated IOP. Multivariable analysis was undertaken to investigate potential predictors of secondary glaucoma with adjustment for within-child correlation in bilateral cataract. Unilateral and bilateral cataract were analysed separately.ResultsComplete follow-up data were available for 235 of 254, 93% of the inception cohort. By 5 years after primary cataract surgery, 20% of children with bilateral cataract and 12% with unilateral had developed secondary glaucoma. Glaucoma related complications had been diagnosed in 24% and 36% of children, respectively. Independent predictors of glaucoma were younger age at surgery (adjusted OR for reduction of week in age: 1.1, 95%C I 1.1 to 1.2, p<0.001); the presence of significant ocular comorbidity (adj OR 3.2, 95% CI 1.1 to 9.6, p=0.01); and shorter axial length (adj OR for each mm 1.7, 95% CI 10.0 to 1, p=0.05) for bilateral cataract. Shorter axial length was the single independent factor in unilateral disease (adj OR 9.6, 95% CI 1.7 to 52, p=0.009)ConclusionsBoth younger age at surgery (the strongest marker of ocular ‘immaturity’) and smaller ocular size (a marker of both immaturity and developmental vulnerability) can be used to identify those at greatest risk of glaucoma due to early life cataract surgery.

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 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.

Prospective analysis of the predictors of glaucoma following surgery for congenital and infantile cataract. Eye (Lond) 2018; 33:796-803. [PMID: 30560916 DOI: 10.1038/s41433-018-0316-8] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Revised: 10/08/2018] [Accepted: 12/02/2018] [Indexed: 11/08/2022] Open
Abstract
PURPOSE A prospective longitudinal cohort study was performed to assess the incidence of and risk factors for the development of glaucoma following surgery for congenital/infantile cataract. METHODS One hundred and one eyes of one hundred and one children, ≤12 years of age who had follow-up of ≥24 months were included. Group I included those who underwent surgery using an anterior approach, group II included those who underwent surgery using a posterior approach, and group III included those who underwent surgery using an anterior approach along with foldable intraocular lens implantation. Standard definitions for glaucoma and glaucoma suspect were used. The Cox proportional hazard model was used to analyze risk factors for glaucoma. RESULTS Group I: 30 eyes (29.7%); group II: 11 eyes (10.9%); group III 60 eyes (59.4%). The incidence of glaucoma + glaucoma suspect was 7.9% (95% CL: 2.6, 13.2%) in the entire group. The incidence in group I was 16.7% (95% CL 3%, 30%), in group II was 18.2% (95% CL: 0, 41%) and in group III was 1.7% (95% CL: 0, 4.9%). Gonioscopy revealed high iris insertion with grade I (modified Shaffer grading) in one eye each in the glaucoma and glaucoma suspect group and open angles in the rest. Age at surgery of ≤3 months (HR: 6.6, 95% CL: 1.4, 30.6, p = 0.01) was found to be a significant risk factor within the aphakic group. CONCLUSIONS Younger age at the time of surgery was the only identifiable risk factor for glaucoma.

Abstract
PURPOSE To compare intraocular pressure measured using the Goldmann applanation tonometer with that measured using the ocular response analyzer after congenital cataract surgery. METHODS This study included 113 eyes of 64 patients who underwent lensectomy and vitrectomy. In all, 36 eyes remained aphakic after surgery. Intraocular lens implantation was performed at the time of surgery in 47 eyes and secondarily in 30 eyes. Corneal hysteresis, corneal resistance factor, and cornea-compensated intraocular pressure were measured. The influences of independent factors on the difference between the cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer were investigated using linear regression analyses. Agreement between the two tonometers was investigated using the Bland and Altman and 95% limits of agreement analysis. RESULTS Central corneal thickness, corneal hysteresis, and corneal resistance factor were 591.2 ± 53.3 µm, 10.83 ± 2.27 mmHg, and 11.36 ± 2.14 mmHg, respectively. Cornea-compensated intraocular pressure (16.75 ± 4.82 mmHg) was significantly higher than intraocular pressure measured with Goldmann applanation tonometer (14.41 ± 2.27 mmHg, p < 0.001). Central corneal thickness (p = 0.02) and corneal hysteresis (p < 0.001) were identified as the main predictors of difference between cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer readings. A 95% limits of agreement for cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer was between -4.86 and 9.53 mmHg in the entire group. Cornea-compensated intraocular pressure showed the best agreement with intraocular pressure measured with Goldmann applanation tonometer in the primary pseudophakic subgroup as compared to the other subgroups. CONCLUSION The Goldmann applanation tonometer and ocular response analyzer cannot be used interchangeably for measuring intraocular pressure after congenital cataract surgery. The difference between the cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer was primarily affected by central corneal thickness and corneal hysteresis. Among the subgroups, the primary pseudophakic subgroup had the thinnest cornea and the highest corneal hysteresis values and demonstrated the best agreement between the two tonometers.

Five-Year Postoperative Outcomes of Bilateral Aphakia and Pseudophakia in Children up to 2 Years of Age: A Randomized Clinical Trial. Am J Ophthalmol 2018; 193:33-44. [PMID: 29906430 DOI: 10.1016/j.ajo.2018.06.005] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2018] [Revised: 06/02/2018] [Accepted: 06/04/2018] [Indexed: 11/20/2022]
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 the long-term efficacy of endoscopic cyclophotocoagulation (ECP) in pediatric glaucoma following cataract surgery (GFCS). METHODS ECP was performed on 35 eyes of 25 patients <16 years of age with GFCS. Patients were followed for a minimum of 2 years. Treatment failure was defined as consecutive postoperative intraocular pressure (IOP) of >24 mm Hg, alternative glaucoma procedure following ECP, or occurrence of visually significant complications. Analysis was performed to estimate risk factors for failure. RESULTS A total of 27 aphakic and 8 pseudophakic eyes were included. Pretreatment IOP averaged 33.9 ± 7.9 mm Hg. Final IOP after a mean follow-up period of 7.2 years was 18.9 ± 8.8 mm Hg (P < 0.001). The success rate was 54% (19/35 eyes). The failure rate was not increased in pseudophakic patients relative to aphakic patients. Patients with single ECP demonstrated preserved visual acuity from baseline to final follow-up. CONCLUSIONS In this patient cohort, with average follow-up period of 7.2 years, ECP was useful in the treatment of pediatric GFCS.

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

Abstract
Aim To study the incidence and risk factors of glaucoma occurring within 1 year following pediatric cataract surgery in Egyptian children. Materials and methods This is a prospective nonrandomized study conducted at Aburich Children’s Hospital, over a period of 1 year on a cohort of Egyptian patients with congenital and infantile cataract. One hundred and fifty eyes of 88 patients were enrolled in this study. All the patients underwent anterior approach removal of lens matter, whereas primary intraocular lens (IOL) implantation was carried at the age of 1 and 2 years for unilateral and bilateral cases respectively. Intraocular pressure (IOP) was measured at 1 week, 1 month, 3 months, 6 months, 9 months, and 1 year. For those who developed glaucoma, time of diagnosis and associated risk factors were reported. Results The incidence of glaucoma was 11.33% (17 of 150 eyes), while incidence of glaucoma suspect was 0.67% (1 of 150 eyes) in the first year following cataract surgery. The majority of the cases (66.7%) were discovered in the first 3 months postcataract surgery. Age at time of cataract surgery, the state of aphakia/pseudophakia, persistent fetal vasculature (PFV), and microphthalmia were not found to be significant predictors of early-onset glaucoma in our study. Conclusion Aphakic glaucoma continues to be a devastating condition with high incidence during first year following cataract surgery. Clinical significance Regular follow-up should start as early as possible following cataract surgery. Further prospective studies with larger study population are required.

Abstract
PURPOSE To review the impact of vitrectomy and tube shunts on mean intraocular pressure (IOP) and number of glaucoma medications in pediatric aphakic glaucoma. METHODS A retrospective review of pediatric patients who underwent combined vitrectomy and glaucoma tube shunt surgery for aphakic glaucoma was conducted. Inclusion criteria were: age 18 years or younger, diagnosis of aphakic glaucoma, preoperative IOP data, and postoperative IOP data for at least 6 months. Mean IOP lowering at 1 year, number of glaucoma medications at 1 year, and surgical complications, including tube occlusion in the postoperative period, were noted. RESULTS The mean ± standard deviation preoperative IOP was 33.9 ± 10.6 mm Hg (range: 18 to 57 mm Hg) with a mean of three topical IOP-lowering medications. A total of 5 (36%) Ahmed and 9 (64%) Baerveldt tube shunts were placed. One of the Baerveldt tube shunt procedures was combined with revision of a traumatically dislocated tube. The mean IOP at 12 months postoperatively was 16.6 ± 5.8 mm Hg (range: 6 to 28 mm Hg; P < .01, t = 3.74, df = 13) with a mean of 2.3 glaucoma medications. There were no cases of tube occlusion, corneal decompensation, endophthalmitis, or retinal detachment over the 12 months of follow-up. CONCLUSIONS Combined vitrectomy and placement of a glaucoma tube shunt can be safe and effective in lowering IOP based on mean IOP values and number of glaucoma medications at 1 year.

Abstract
PURPOSE To evaluate the long-term impact of bilateral cataract surgery on postoperative complications, influence of age at surgery on the pattern of axial growth and central corneal thickness (CCT), and visual and orthoptic assessment in microphthalmic eyes. SETTING Iladevi Cataract and IOL Research Centre, Ahmedabad, India. DESIGN Prospective longitudinal study. METHODS This study assessed children with microphthalmos who had bilateral congenital cataract surgery. Microphthalmos was defined as an eye that has an axial length (AL) that was 2 standard deviations smaller than what is normally expected at that age. All eyes were left aphakic. One of the 2 eyes was randomly selected for analysis. Postoperative complications, AL, CCT, and visual acuity were documented. RESULTS This study included 72 eys of 36 children. The mean age of the patients was 4.8 months ± 6.2 (SD) (range 0.5 to 15 months). Postoperative complications included secondary glaucoma (11/36, 30.6%), visual axis obscuration (4/36, 11.1%), and posterior synechiae (10/36, 27.8%). A significant rate of change was observed in axial growth up to 4 years and in CCT up to 3 years postoperatively. When age at the time of surgery was correlated with the profile of the rate of change in AL and CCT at 1 month and 1, 2, and 4 years, statistically significant differences in AL and CCT at all timepoints were found. Loss of vision after surgery occurred in 2 eyes. CONCLUSION After early surgical intervention, an acceptable rate of serious postoperative complications and good visual outcomes were obtained in microphthalmic 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 To report the long-term risk of glaucoma development in children following congenital cataract surgery. DESIGN Retrospective interventional consecutive case series. METHODS We retrospectively reviewed the records of 62 eyes of 37 children who underwent congenital cataract surgery when <7 months of age by the same surgeon using a limbal approach. The Kaplan-Meier method was used to calculate the probability of an eye's developing glaucoma and/or becoming a glaucoma suspect over time. RESULTS The median age of surgery was 2.0 months and the median follow-up after cataract surgery was 7.9 years (range, 3.2-23.5 years). Nine eyes (14.5%) developed glaucoma a median of 4.3 months after cataract surgery and an additional 16 eyes (25.8%) were diagnosed as glaucoma suspects a median of 8.0 years after cataract surgery. The probability of an eye's developing glaucoma was estimated to be 19.5% (95% CI: 10.0%-36.1%) by 10 years after congenital cataract surgery. When the probability of glaucoma and glaucoma suspect were combined, the risk increased to 63.0% (95% CI: 43.6%-82.3%). CONCLUSIONS Long-term monitoring of eyes after congenital cataract surgery is important because we estimate that nearly two thirds of these eyes will develop glaucoma or become glaucoma suspects by 10 years after cataract surgery.

Abstract
AIM To determine the incidence and risk factors of secondary glaucoma after pediatric cataract surgery. METHODS Two hundred and forty nine eyes of 148 patients underwent cataract surgery without intraocular lens (IOL) implantation (group 1), and 220 eyes of 129 patients underwent cataract surgery with IOL implantation (group 2) retrospectively, were evaluated between 2000 and 2011. The outcome measure was the presence or absence of post-cataract surgery glaucoma, defined as an intraocular pressure (IOP) ≥26mmHg, as measured on at least two occasions along with corneal or optic nerve changes. RESULTS The mean follow-up periods of group 1 and 2 were (60.86±30.95) months (12-123 months) and (62.11±31.29) months (14-115 months) respectively. In group 1, 12 eyes of 8 patients (4.8%) developed glaucoma. None of the patients developed glaucoma after surgery in group 2. The mean age of the patients at the cataract surgery was (2.58±0.90) months (1 month-4 months) and the average period for glaucoma development after surgery was (9.50±4.33) months (4-16 months) in group 1. Three of the 12 glaucomatous eyes were controlled with antiglaucomatous medication and 9 eyes underwent trabeculectomy+mitomycin C surgery. One patient underwent a second trabeculectomy + mitomycin C operation for both of his eyes. CONCLUSION The incidence of glaucoma after pediatric cataract surgery is very low in patients in whom IOL is implanted.

Clin Exp Ophthalmol 2013; 41:653-61. [PMID: 23332011 DOI: 10.1111/ceo.12067] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2012] [Accepted: 01/03/2013] [Indexed: 11/30/2022]
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
PURPOSE To determine the incidence and risk factors for delayed-onset intraocular pressure (IOP) elevations after vitrectomy for Stages 4 and 5 retinopathy of prematurity and, in addition, to determine the results of treating the IOP elevations. METHODS Fifty-five consecutive eyes with successful retinal reattachment and at least 24 months of follow-up after vitrectomy were studied. The ophthalmic examinations included slit-lamp biomicroscopy, wide-field digital retinal imaging, and IOP measurements. Eyes were classified into 2 groups: eyes with a postoperative IOP elevation to ≥ 21 mmHg and eyes whose IOP was always <21 mmHg. RESULTS Eight eyes (14.5%) developed an IOP elevation to ≥ 21 mmHg from 2 months to 4 months (median: 2.5 months) after the vitrectomy. In two of these eyes, the IOP was controlled with antiglaucoma medications. In the other six eyes, trabeculotomy for eyes with open angles and trabeculectomy or goniosynechialysis for eyes with closed angles were performed. The IOPs were successfully controlled after an average of 1.5 glaucoma surgeries. Multivariate logistic regression analyses identified that a young gestational age (odds ratio = 1.147, 95% confidence interval: 1.024-1.346) and lensectomy (odds ratio = 8.795, 95% confidence interval: 1.262-183.3) were significantly associated with the IOP elevation. CONCLUSION Delayed-onset IOP elevation after vitrectomy for retinopathy of prematurity occurs in 14.5% of the eyes, and it is significantly associated with a young gestational age and presence of lensectomy.

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
OBJECTIVES To report the incidence of glaucoma and glaucoma suspects in the IATS, and to evaluate risk factors for the development of a glaucoma-related adverse event in patients in the IATS in the first year of follow-up. METHODS A total of 114 infants between 1 and 6 months of age with a unilateral congenital cataract were assigned to undergo cataract surgery either with or without an intraocular lens implant. Standardized definitions of glaucoma and glaucoma suspect were created and used in the IATS. RESULTS Of these 114 patients, 10 (9%) developed glaucoma and 4 (4%) had glaucoma suspect, for a total of 14 patients (12%) with a glaucoma-related adverse event in the treated eye through the first year of follow-up. Of the 57 patients who underwent lensectomy and anterior vitrectomy, 5 (9%) developed a glaucoma-related adverse event; of the 57 patients who underwent an intraocular lens implant, 9 (16%) developed a glaucoma-related adverse event. The odds of developing a glaucoma-related adverse event were 3.1 times higher for a child with persistent fetal vasculature and 1.6 times higher for each month of age younger at cataract surgery. CONCLUSIONS Modern surgical techniques do not eliminate the early development of glaucoma following congenital cataract surgery with or without an intraocular lens implant. Younger patients with or without persistent fetal vasculature seem more likely to develop a glaucoma-related adverse event in the first year of follow-up. Vigilance for the early development of glaucoma is needed following congenital cataract surgery, especially when surgery is performed during early infancy or for a child with persistent fetal vasculature. Five-year follow-up data for the IATS will likely reveal more glaucoma-related adverse events. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00212134.

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.

Abstract
PURPOSE To report the results of secondary in-the-bag intraocular lens (IOL) implantation compared to secondary sulcus IOL implantation in eyes that received cataract extraction during early infancy. METHODS This was a comparative retrospective study. Data were collected for the ages at cataract extraction and at secondary IOL implantation, the length of follow-up, the reasons for IOL insertion, postoperative complications, and pre- and postoperative best-corrected visual acuity. Eyes with less than 6 months of follow-up were excluded from the analysis of postoperative outcome but were included in the rest of the analysis. RESULTS Thirty-three eyes received in-the-bag secondary IOL implantation at the Storm Eye Institute, Medical University of South Carolina, during the past 10 years and were compared with 21 eyes that received secondary sulcus IOL implantation during the same time period. Both groups had cataract extraction during the first 4 months of life. The 2 groups were comparable in terms of age at secondary IOL implantation, sex, ethnicity, laterality, and eye measurements except for a longer mean axial length for the eyes implanted in the sulcus. The complications were comparable in both groups. The last follow-up best-corrected visual acuity clustered around a median of 20/40 and was not significantly different between the 2 groups or from the median preoperative best-corrected visual acuity of 20/50. CONCLUSIONS Secondary in-the-bag IOL implantation has comparable early results with sulcus IOL implantation while still allowing the use of single-piece acrylic IOLs and offering the chance, in suitable eyes, for implanting a secondary IOL in the anatomical space of the capsular bag.

Abstract
AIM To observe the central corneal thickness (CCT) changes in infants and young children who had been undergone bilateral congenital cataract surgery, and to compare the changes with normal control group which was selected from healthy population. METHODS A cross section case-control study contained 28 cases (56 eyes) of bilateral aphakia (aphakic group) due to congenital cataract surgery combining with posterior continuous curvilinear capsulorhexis and with anterior vitrectomy during 2-6 months after birth. Fourteen children (28 eyes) of age-sex matched with the aphalic group were selected as normal control group. CCT and intraocular pressure (IOP) were measured postoperatively and the results were compared between groups. RESULTS The mean CCT was 653.5±82.4μm in the aphakic group and 579.6±39.2μm in the control group, with a significant difference (P=0.000). The mean value of IOP in aphakic group (22.0±1.6mmHg) was greater than that of control group (16.9±2.1mmHg), P=0.023. There was a negative correlation between age and CCT in normal control group (r=-0.531, P=0.026), and there was no correlation in bilateral aphakia group (r=-0.324, P=0.165) CONCLUSION Aphakic children due to congenital cataract surgery have a greater CCT than normal children. It is necessary to consider CCT in evaluating IOP for children after congenital cataract surgery.

Abstract
PURPOSE To investigate the outcome of trabeculotomy and/or goniotomy for pediatric aphakic glaucoma. METHODS Retrospective chart review of consecutive children who had congenital cataract surgery between 1990 and 2006 and required goniotomy and/or trabeculotomy for aphakic glaucoma. Treatment success was defined as postoperative intraocular pressure of <or=24 mm Hg despite topical medication use, avoidance of trabeculectomy or shunt placement, and no visually significant complications in the follow-up period. Exclusion criteria included a diagnosis of anterior segment dysgenesis, microcornea, and glaucoma at the time of cataract surgery, and follow-up less than 1 year. RESULTS A total of 14 eyes of 11 patients met inclusion criteria, with a mean follow-up of 4.7 years. Of theses, 2 eyes had goniotomy alone, 3 eyes had goniotomy followed by trabeculotomy, and 9 eyes had trabeculotomy alone. Mean IOP before angle surgery was 35 +/- 10 mm Hg. Mean IOP at the last recorded visit was 22 +/- 4 mm Hg (p = 0.0005). Treatment success was observed in 8 of the 14 eyes (57.1%), with a mean number of angle procedures of 1.4 per eye: 6 eyes (42.8%) were successful after a single angle surgery, each involving an initial trabeculotomy; 3 eyes (21.4%) underwent subsequent shunt placement after initial goniotomy at 6 months, 1.3 years, and 5.5 years after the last angle surgery. CONCLUSIONS When intraocular surgery is indicated to control IOP in pediatric aphakic glaucoma, trabeculotomy and/or goniotomy can be successful in the majority of eyes and may decrease the need for filtering and shunting procedures.

Abstract
AIMS To analyse the incidence of glaucoma in children undergoing cataract surgery and determine whether early surgery is associated with increased risk of glaucoma. METHODS A retrospective chart review of all children aged 14 years or less who had surgery for congenital or developmental cataract at one unit over the last 20 years. The children were divided into three groups; group 1 consisting of children aged < or =50 days at surgery, group 2 those aged 51 days to 1 year, and group 3 aged 1-14 years. RESULTS We identified a total of 104 eyes of 74 children. The medical records for 100 eyes (71 children) were available for review. In all, 17 eyes (12 children) were aged < or =50 days at surgery, none of which have developed glaucoma. Group 2 consisted of 28 eyes (17 children) with one patient developing glaucoma in both eyes 11 years after surgery. Group 3 consisted of 55 eyes (42 children), none of which have developed glaucoma. After a median follow-up period of 4.9 years (range 0.6-19.6 years, mean 6.4 +/- 5.2 years) 2% of eyes had developed glaucoma. There was no significant difference in the length of follow-up between groups (H=2.979, P=0.22, Kruskal-Wallis Test). CONCLUSIONS There was a low incidence of glaucoma in our series and this was not increased in those having surgery in the first 6 weeks of life. Our findings contribute further evidence for the variability in prevalence of glaucoma after paediatric cataract extraction in the literature and suggest that factors other than age at surgery are important risk factors for this condition.

Abstract
PURPOSE To determine the incidence and risk factors for glaucoma in pseudophakic and aphakic eyes following surgery for congenital cataract within the first year of life. METHODS We conducted a review of all cataract surgery performed at our unit over a 23-year period. Age at surgery, corneal diameter, intraocular lens implantation, presence of persistent foetal vasculature and visual axis opacification (VAO) were documented. Time to development of glaucoma, management and outcome were determined. One eye was selected randomly for analysis in cases of bilateral cataract. RESULTS Duration of follow-up was significantly longer (p < 0.001) in the aphakic (113 +/- 69 months) compared to the pseudophakic group (56 +/- 44 months). Age at surgery was significantly less (p = 0.01) in the aphakic group. The incidence of glaucoma was significantly greater (p = 0.02) in the aphakic (15 eyes, 33%) compared to the pseudophakic (seven eyes, 13%) group. Each eye that developed glaucoma underwent cataract extraction aged < or = 2.5 months. Analysis of all eyes that underwent surgery aged < or = 2.5 months revealed no statistical difference (p = 0.08) in the incidence of glaucoma. Smaller corneal diameter and VAO were not associated with increased risk of glaucoma development. Ahmed valves proved effective in controlling intraocular pressure but visual outcome was poor in the majority of cases. CONCLUSION Surgery for congenital cataract at an early age increases the risk of glaucoma development, regardless of whether the eye is aphakic or pseudophakic. Intraocular pressure control with Ahmed valves is frequently required. Glaucomatous damage and dense amblyopia contribute to poor visual outcome in these eyes.

Abstract
PURPOSE To report the incidence of and factors associated with postoperative open-angle glaucoma in a nationally representative group of children undergoing surgery for congenital or infantile cataract. DESIGN Noncomparative interventional cohort study. PARTICIPANTS All children in the United Kingdom who were newly diagnosed with congenital or infantile cataract in a 12-month period in 1995 and 1996 (the British Congenital/Infantile Cataract Study) were eligible for this study. One hundred sixty-five children with congenital or infantile cataract underwent cataract surgery. METHODS All the children were traced through their managing ophthalmologists. Standardized outcome data were collected at least 6 years after diagnosis. For children undergoing cataract extraction, Cox regression analysis was performed to determine incidence of postoperative open-angle glaucoma and the effect of key factors considered, a priori, potentially to be associated with it (i.e., age at detection and surgery, type of cataract surgery, primary intraocular lens implantation, severe postoperative uveitis, and microphthalmia). MAIN OUTCOME MEASURES Development of open-angle glaucoma after cataract surgery. RESULTS Postoperative glaucoma developed in 27 of 275 eyes of 165 children who underwent cataract surgery. The overall annual incidence of postoperative glaucoma was 5.25 per 100 cataract operations. The median time to development of postoperative glaucoma was 1.34 years (range, 0.39 months-6.73 years). Younger age at detection of cataract was the only factor independently associated with the development of glaucoma when all other factors of interest (which were all statistically associated with age at detection) were accounted for. A 10-fold increase in the age at detection (for example, 30 days compared with 3 days) was associated with a 64% decrease in the hazard ratio (95% confidence interval, 41%-79%; P<0.001). CONCLUSIONS Median time to development of postoperative open-angle glaucoma in the present study was lower than that reported previously, emphasizing the need for vigilance from the early postoperative period. Earlier detection of cataract was the only significant factor associated with the development of glaucoma after surgery for congenital cataract.
