BACKGROUND/AIMS: There is a paucity of large trials investigating the effect of management strategies for paediatric non-infectious uveitis on complications requiring surgery. The purpose of our study is to investigate whether earlier initiation of systemic immunosuppression in paediatric non-infectious uveitis is associated with fewer ophthalmic surgeries. METHODS: A retrospective review was conducted on 48 children with non-infectious uveitis assessed in 1998-2013. Patients were divided into uveitis diagnosed before December 2008 (group 1) and after January 2009 (group 2). Duration from uveitis onset to methotrexate initiation (U-MTX) and biological addition (U-Biologic) were reviewed. Follow-up visits with topical corticosteroids >3 times daily and active uveitis (≥1+ cells) during 3.5 years were documented. The main outcome measure was the need for ≥1 ophthalmic surgery at 3.5 years. RESULTS: In group 1, 69.5% of patients required ≥1 ophthalmic surgery at 3.5 years versus 26.9% in group 2 (p=0.005). U-MTX was 28.9±11.8 weeks and 14.2±10.0 weeks for groups 1 and 2 (p=0.028). U-Biologic was 134.6±46.0 weeks and 82.3±43.3 weeks for groups 1 and 2 (p=0.0016). Corticosteroid use >3 times daily was 85.9±52.7 weeks and 14.6±11.1 weeks for groups 1 and 2. Multivariate regression showed methotrexate initiation within 6 months of uveitis onset lowered the likelihood of needing ophthalmic surgery at 3.5 years (OR=6.2, 95% CI 1.2 to 33.4; p=0.033). Univariate regression demonstrated biological addition within 18 months of uveitis onset reduced the likelihood of requiring ophthalmic surgery (OR 12.57, 95% CI 1.28 to 123.48; p=0.030). CONCLUSION: Earlier control of uveitis by addition of immunosuppressive therapy reduced the need for ophthalmic surgery.

We analyzed clinical and histopathologic data of 97 pediatric patients who underwent excision of dermoid cysts. On review, 16.5% of the sample population demonstrated localized chronic inflammatory changes, including the presence of giant cells and epithelial disruption. These features were considered indicative of prior cyst rupture. Age at time of initial presentation was significantly older and cyst size was significantly larger in patients with histopathologic signs of previous rupture. Longer time to presentation and time to excision were associated with increased odds of spontaneous rupture.

BACKGROUND: Preterm infants with anaemia are treated with recombinant human erythropoietin (rhEPO). It is debated whether rhEPO treatment is a risk factor for retinopathy of prematurity (ROP). We evaluated longitudinal EPO and haemoglobin levels, blood transfusions and neonatal morbidities as risk factors for severe ROP. METHOD: This prospective study included 78 Swedish infants, born <28 weeks gestational age (GA), screened for ROP. We tested serum EPO levels on postnatal days 1, 7, 14 and 28 and at postmenstrual ages 32, 36 and 40 weeks. Haemoglobin levels and blood transfusions were recorded during postnatal weeks 1-4. Anaemia was defined as haemoglobin ≤110 g/L. RESULTS: During postnatal week 1, infants with severe ROP requiring treatment (28%) more frequently developed anaemia (42.9% versus 8.0%, P = 0.003) and had higher mean EPO levels (postnatal day 7: 14.2 versus 10.8 mIU/mL, P = 0.003) compared to infants with no or less severe ROP not requiring treatment. In multivariable analyses, GA and anaemia during week 1 remained significant risk factors, but elevated EPO level postnatal day 7 was no longer significant. CONCLUSIONS: Among infants born <28 weeks GA, anaemia during week 1 was a significant risk factor for severe ROP requiring treatment but not elevated EPO levels.

Purpose: Extremely preterm infants are at increased risk for retinopathy of prematurity (ROP). We previously identified several inflammatory proteins that were expressed early in life and are associated with an increased risk of ROP and several angiogenic and neurotrophic growth factors in the neonatal systemic circulation that are associated with a lower risk of ROP. In this paper, we report the results of a set of analyses designed to test the hypothesis that placental CpG methylation levels of 12 inflammation-, angiogenic-, and neurotrophic-associated genes predict the occurrence of prethreshold ROP in extremely preterm newborns. Methods: We used placental CpG methylation data from 395 newborns from the Extremely Low Gestational Age Newborns study. Results: Multivariable regression models revealed that placental DNA methylation of 16 CpG sites representing 8 genes were associated with prethreshold ROP. Specifically, CpG methylation in the serum amyloid A SAA1 and SAA2, brain-derived neurotrophic factor (BDNF), myeloperoxidase (MPO), C-reactive protein (CRP), angiopoietin 1 (ANGPT1), and tumor necrosis factor receptor superfamily member 1B (TNFRSF1B) genes was associated with a lower risk of prethreshold ROP. Conversely, CpG methylation at three probes within tumor necrosis factor receptor superfamily member 1A (TNFRSF1A) and in two alternative probes within the BDNF and ANGPT1 genes was associated with an increased risk of ROP. Conclusions: CpG methylation may be a useful marker for improving ROP prediction, opening the opportunity for early intervention to lessen disease severity.

PURPOSE: To compare the visual outcomes and adverse events associated with optical correction using an intraocular lens (IOL), contact lenses, or spectacles after cataract surgery in children 2 years of age or younger. METHODS: Literature searches were conducted in PubMed, the Cochrane Library, and the databases of clinical trials in February 2019, without date or language restrictions. The search resulted in 194 potentially relevant citations, and 34 were selected for full-text review. Fourteen studies were determined to be relevant to the assessment criteria and were selected for inclusion in this assessment. The panel methodologist then assigned a level of evidence rating to these studies. RESULTS: Intraocular lenses were associated with visual outcomes similar to outcomes for contact lenses or spectacles for children who had both bilateral and unilateral cataracts. Intraocular lenses were also associated with an increased risk of visual axis opacities. All treatments were associated with a similar incidence of glaucoma. Although ocular growth was similar for all treatments, infants younger than 6 months who underwent IOL implantation had large myopic shifts that often resulted in high myopia or severe anisometropia later in childhood. Corneal endothelial cell counts were lower in eyes that underwent IOL implantation. The incidence of strabismus was similar with all treatments. CONCLUSIONS: Intraocular lens implantation is not recommended for children 6 months of age or younger because there is a higher incidence of visual axis opacities with this treatment compared with aphakia. The best available evidence suggests that IOL implantation can be done safely with acceptable side effects in children older than 6 months of age. However, the unpredictability of ocular growth means that these children will often have large refractive errors later in childhood that may necessitate an IOL exchange or wearing spectacles or contact lenses with a large refractive correction. In addition, the training and experience of the surgeon as well as ocular and systemic comorbidities should be taken into consideration when deciding whether IOL implantation would be appropriate.

PURPOSE: Assessment of combined impact of intracranial pressure (ICH) and obstructive sleep apnea (OSA) on optic nerve function in children with craniosynostosis (CS). DESIGN: Retrospective cross-sectional study METHODS: Patients treated at Boston Children's Hospital for CS who had an ophthalmic examination that included pattern reversal (pr)VEP (2013-2014) and history of ICH based on direct measurement, papilledema, or classic features on neuroimaging and during cranial vault expansion were included. History of OSA was determined by polysomnography and associated conditions, including apnea and (adeno)tonsillectomy. Subjects were divided into four groups: (1) resolved ICH absent history of OSA; (2) resolved ICH with history of OSA; (3) recurrent ICH absent history of OSA; and (4) recurrent ICH with history of OSA. Predictor variables included latency of P100 component of prVEP, best-corrected visual acuity, optic nerve appearance, visual fields and global RNFL. Primary outcome was association of prolonged P100 latency with resolved versus recurrent ICH and OSA. RESULTS: Twenty-eight children met inclusion criteria (mean age 11.6 ± 6.9 years): group 1 (N = 3); group 2 (N = 6); group 3 (N = 8); group 4 (N = 11). P100 latencies were not prolonged in groups 1 and 2. Three of 8 in group 3 and 9 of 11 in group 4 had prolonged P100 latency. Group 4 was significantly worse than group 3 (P=0.005). CONCLUSIONS: History of OSA, in addition to recurrent ICH, is associated with greatest risk of optic neuropathy with CS. Ophthalmologists should encourage early management of OSA as well as ICH to optimize ophthalmic outcomes.

To better understand AAPOS member pediatric ophthalmologists' knowledge and needs regarding genetic eye disorders, the AAPOS Genetic Eye Disease Task Force developed a 16-question survey that was circulated to national and international AAPOS members. Responses to questions on practice patterns, baseline knowledge, and educational interests regarding patients with suspected ophthalmic genetic disorders were collected. A majority of respondents (93%) evaluate patients with suspected genetic disorders. Knowledge gaps were present in heritability of certain conditions, genetic testing strategies, and referral to clinical trials. Most respondents expressed interest in further education in these areas. A model for care is proposed as a first step in the education process.

The presence of optic nerve swelling in pediatric patients is a frequent cause for referral to pediatric ophthalmologists and neuro-ophthalmologists because this finding can be the harbinger of serious neurologic disease including brain tumor, demyelinating disease, infiltrative disease of the optic nerve, or idiopathic intracranial hypertension. Optic nerve head drusen (ONHD) are common and can be particularly difficult to distinguish from true optic nerve swelling in pediatric patients because the ONHD are typically buried beneath the substance of the optic nerve. Correct identification of ONHD is relevant because of the visual morbidity associated with this condition and because of the need to distinguish pseudopapilledema secondary to ONHD from true optic nerve swelling. A variety of imaging modalities may be employed to evaluate for the presence of ONHD, including ultrasound, optical coherence tomography (OCT), enhanced depth imaging-OCT, fluorescein angiography, fundus autofluorescence, and optical coherence tomography angiography. To date, there is no consensus as to which of these techniques is most accurate and which should be part of a standardized evaluation for children suspected of ONHD. This review examines the recent literature analyzing these diagnostic tools and summarizes data regarding best practices for identifying ONHD.

Intraocular lens (IOL) implantation in pediatric eyes with insufficient capsular support is challenging and there are multiple IOL options. These include placement of an IOL within the capsular bag with a capsular tension ring, a scleral-fixated posterior-chamber IOL (PCIOL) with or without capsular tension segment or ring, an intra-scleral fixated IOL, an iris-sutured PCIOL, or an anterior chamber iris-fixated IOL. We reviewed 48 articles and 1 published abstract describing the surgical techniques, complications and visual outcomes of different IOL options in the management of aphakic pediatric eyes with insufficient capsular support. The present review found that the visual acuity outcomes of various IOLs are comparable. Furthermore, each .

PURPOSE: To determine the frequency of receded near point of convergence (NPC) in patients with chronic concussion-related symptoms, and among those with receded NPC to enumerate the frequency of convergence insufficiency and other oculomotor disorders. STUDY: Design: Retrospective cross-sectional study METHODS: Clinic charts were retrospectively reviewed for the prior 3.5 years to identify all patients <21 years old who were >28 days post-concussion, had chronic concussion-related symptoms, had normal visual acuity, and received a comprehensive sensorimotor examination. The frequency of receded NPC and oculomotor diagnoses were determined. RESULTS: Of the 83 eligible patients, 74 (89%) had receded NPC. Of these, 70 (95%) had oculomotor disorders; 30 (41%) had disorders of accommodation only, 21 (28%) had convergence insufficiency and accommodation deficits, and 6 (8%) had convergence insufficiency only. Six (8%) had a convergence deficit other than convergence insufficiency (all with concurrent accommodative disorders), 4 (5%) had both a non-specific vergence dysfunction and accommodation deficits, 2 (3%) had convergence excess only, and 1 (1%) had both convergence excess and accommodative deficits. CONCLUSION: A receded NPC was present in the majority of young patients with chronic post-concussion symptoms. Associated with numerous underlying oculomotor dysfunctions, the clinical finding of a receded NPC is not synonymous with the diagnosis of convergence insufficiency. Because treatment options for the various oculomotor dysfunctions differ, it is prudent that these patients undergo a thorough examination of their vergence and accommodative systems so that an accurate diagnosis can be made and appropriate treatment prescribed.

PURPOSE: To evaluate outcomes of unilateral cataract surgery in children 7 to 24 months of age. DESIGN: Retrospective case series at 10 Infant Aphakia Treatment Study (IATS) sites. PARTICIPANTS: The Toddler Aphakia and Pseudophakia Study is a registry of children treated by surgeons who participated in the IATS. METHODS: Children underwent unilateral cataract surgery with or without intraocular lens (IOL) placement during the IATS enrollment years of 2004 and 2010. MAIN OUTCOME MEASURES: Intraoperative complications, adverse events (AEs), visual acuity, and strabismus. RESULTS: Fifty-six children were included with a mean postoperative follow-up of 47.6 months. Median age at cataract surgery was 13.9 months (range, 7.2-22.9). Ninety-two percent received a primary IOL. Intraoperative complications occurred in 4 patients (7%). At 5 years of age, visual acuity of treated eyes was very good (≥20/40) in 11% and poor (≤20/200) in 44%. Adverse events were identified in 24%, with a 4% incidence of glaucoma suspect. An additional unplanned intraocular surgery occurred in 14% of children. Neither AEs nor intraocular reoperations were more common for children with surgery at 7 to 12 months of age than for those who underwent surgery at 13 to 24 months of age (AE rate, 21% vs. 25% [P = 0.60]; reoperation rate, 13% vs. 16% [P = 1.00]). CONCLUSIONS: Although most children underwent IOL implantation concurrent with unilateral cataract removal, the incidence of complications, reoperations, and glaucoma was low when surgery was performed between 7 and 24 months of age and compared favorably with same-site IATS data for infants undergoing surgery before 7 months of age. Our study showed that IOL implantation is relatively safe in children older than 6 months and younger than 2 years.

PURPOSE: To evaluate the effect of a computer-based training program-Massachusetts Eye & Ear ROP Trainer-on residents' knowledge of retinopathy of prematurity (ROP) management. METHODS: In this prospective, randomized study, ophthalmology residents from nine different training programs consented to participate. Those who completed the study were randomly assigned to either the Trainer or the control group. The ROP Trainer was created using clinical cases encompassing the stages of ROP in digital pictures and videos. It includes sections on screening decisions, examination techniques, and diagnosis, and a reference section with the expert video clips and a searchable image library. Subjects in the control group were asked to study standard print material on ROP. A pre- and post-test, consisting of theoretical and practical (diagnosis) questions, and a post-intervention satisfaction test were administered. Accuracy of ROP diagnosis was assessed. RESULTS: A total of 180 residents agreed to participate, of whom 60 completed the study. Residents in the Trainer group had statistically significant improvements (P = 0.003) in ROP knowledge and diagnostic ability (P = 0.005). Residents randomized to the Trainer group were more satisfied with the training materials than were those in the control group. There was no significant difference in improving knowledge by year of training, sex, or country. Considering all training levels, a statistically significant increase was observed in sensitivity for the diagnosis of preplus or worse, zone I or II, ROP stage, category, and aggressive posterior ROP in the Trainer group. CONCLUSIONS: In this study, the Trainer was shown to significantly improve ROP knowledge and diagnostic skills of residents, regardless of sex, year, of training, or country.

OBJECTIVES: We assessed the clinical characteristics of primary intracranial hypertension (PIH) in children using a newly recommended threshold for cerebrospinal fluid opening pressure (280 mm HO). METHOD: Cross-sectional study of patients age ≤21 years who had a lumbar puncture done for evaluation of PIH. Patients were excluded if lumbar puncture was done for a suspected infection, seizure, mental status changes, multiple sclerosis, or Guillain-Barre syndrome. Cases were identified using a text-search module followed by manual review. We performed χ2 analysis for categorical data and Mann-Whitney U test for continuous data, followed by a binary logistic regression. RESULTS: We identified 374 patients of whom 67% were female, median age was 13 years interquartile range (11 to 16 years), and admission rate was 24%. Using an opening pressure cutoff of 250 mm HO, 127 patients (34%) were identified as having PIH, whereas using the new cutoff 105 patients (28%) met PIH criteria. Predictors for PIH included optic disc edema or sixth nerve palsy using both old, odds ratio (OR) 7.6 (4.3, 13.5), and new cutoffs, OR 9.7 (95% confidence interval 5.1, 18.5). Headache duration ≤61 days is predictive of PIH using the new cutoff OR 4.1 (95% confidence interval 1.3, 12.8). A model is presented which stratifies patients into groups with low (7%), medium (18%), and high (greater than 42%) risk of PIH. CONCLUSIONS: A higher cerebrospinal fluid opening pressure threshold in the criteria of PIH is associated with PIH patients with a different symptom profile. Children with optic disc edema, bulging fontanel or sixth nerve palsy, are at increased risk for PIH.

OBJECTIVE:  To evaluate to what extent indicators of placenta insufficiency are associated with low concentrations of insulin-like growth factor 1 (IGF-1) and IGF-1-binding protein-1 (IGFBP-1) in neonatal blood, and to what extent the concentrations of these growth factors are associated with concentrations of proteins with inflammatory, neurotrophic, or angiogenic properties. STUDY DESIGN:  Using multiplex immunoassays, we measured the concentrations of IGF-1 and IGFBP-1, as well as 25 other proteins in blood spots collected weekly from ≥ 880 infants born before the 28th week of gestation, and sought correlates of concentrations in the top and bottom quartiles for gestational age and day the specimen was collected. RESULTS:  Medically indicated delivery and severe fetal growth restriction (sFGR) were associated with low concentrations of IGF-1 on the first postnatal day and with high concentrations of IGFBP-1 on almost all days. Elevated concentrations of IGF-1 and IGFBP-1 were accompanied by elevated concentrations of many other proteins with inflammatory, neurotrophic, or angiogenic properties. CONCLUSION:  Disorders associated with impaired placenta implantation and sFGR appear to account for a relative paucity of IGF-1 on the first postnatal day. Elevated concentrations of IGF-1 and especially IGFBP-1 were associated with same-day elevated concentrations of inflammatory, neurotrophic, and angiogenic proteins.

PURPOSE: To report the outcomes of prosthetic replacement of the ocular surface ecosystem (PROSE) treatment in pediatric patients with chronic ocular surface disease associated with Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). DESIGN: Retrospective, interventional case series. METHODS: Patients aged 18 years or younger seen in consultation for PROSE treatment at a single center between January 1992 and December 2016 with a history of SJS/TEN were reviewed. Demographics, etiology of SJS/TEN, age at treatment milestones, best-corrected visual acuity (BCVA) at treatment milestones, and treatment failures were recorded. BCVA at the initial presentation visit was compared to BCVA at the time of PROSE device dispense and at the last recorded visit. RESULTS: Twenty-seven female and 22 male patients were reviewed. Reported etiology was antibiotic (n = 19), antiepileptic (n = 9), antipyretic (n = 9), other (n = 3), and unknown (n = 9). The mean age was 6.4 years at disease onset and 9.3 years at time of initial presentation. The mean duration of follow-up was 5.45 years. The median BCVA at the initial presentation was 0.6 logMAR (20/80 Snellen), and was significantly improved to 0.18 logMAR (20/30 Snellen) at the time a PROSE device was dispensed (P < .0001). The median BCVA at the last recorded visit was significantly improved to 0.18 logMAR (20/30 Snellen, P = .0004). There were 15 patients who failed PROSE treatment (30.6%). CONCLUSIONS: PROSE treatment is feasible in over two thirds of pediatric patients with chronic ocular surface disease related to SJS/TEN and results in significant improvement in vision that is durable over a period of many years.

If homonymous hemianopia develops in childhood it is frequently accompanied by strabismus. In some of these cases the strabismus increases the size of the binocular visual field. We determined how prevalent visual-field-expanding strabismus is in children who have homonymous hemianopia. Medical records were examined from 103 hemianopic patients with exotropia (XT) or esotropia (ET). For each participant, we determined whether their strabismus was in a direction that resulted in visual field expansion (i.e. left exotropia with left homonymous hemianopia). Ages at which hemianopia and strabismus were first noted were compared to determine which developed first. The prevalence of XT (24%) and ET (9%) with homonymous hemianopia were both much higher than in the general population (1.5% and 5%, respectively). More strabismic eyes pointed to the blind than seeing side (62 vs 41, 60% vs. 40%, p = 0.02). Exotropic eyes were five times more likely to point to the blind side than esotropic eyes (85% vs 15%). Strabismus, especially exotropia, is much more common in pediatric homonymous hemianopia than in the general population. The strabismus is significantly more often in a visual field-expanding direction. These results support an adaptive role for the strabismus. Patients with HH and exotropia or esotropia should be aware that their visual field could be reduced by strabismus surgery.

AIM: This nonsystematic review examined differences in the composition of raw maternal breastmilk and pasteurised donor milk and possible health effects on preterm infants. METHODS: We searched PubMed up to July 2018 for studies published in English that focused on four comparisons as follows: raw maternal milk versus donor milk, human milk before and after Holder pasteurisation, milk from mothers who delivered preterm and at term and milk collected during early and late lactation. We also searched for possible effects of the milk components, as well as the effects of maternal and donor milk on preterm infants' health. RESULTS: Raw maternal milk contained factors involved in antioxidant and anti-inflammatory defence, gut microbiome establishment and the maturation of immune defences, food tolerability and metabolism. Many of these factors were reduced or abolished in processed donor milk. Both maternal milk and donor milk have been associated with a reduced incidence of necrotising enterocolitis. High-dose feeding with maternal milk during the neonatal period reportedly reduced the risk of other morbidities and promoted growth and neurodevelopment. CONCLUSION: Many of the components in raw maternal breastmilk were lacking in pasteurised donor milk, which was inferior in promoting the growth and development of very preterm infants.

Although there are many anecdotal reports of children with developmental dyslexia complaining of vision symptoms when reading, empirical studies are lacking. The primary aim of the present study was to document self-reported vision-related symptoms in children with developmental dyslexia and typically reading peers. We also explored whether vision symptoms were correlated with sensorimotor measures of vergence, accommodation and ocular motor tracking skills. Using a prospective group comparison observational design, we assessed 28 children with developmental dyslexia (DD) and 33 typically reading children (TR) 7-11 years of age. Participants completed psychoeducational testing, a comprehensive sensorimotor eye examination, and the Convergence Insufficiency Symptom Survey (CISS), which includes 9 items pertaining to vision-related symptoms (CISS-V) and 6 that could have cognitive influence (CISS-C). CISS-V were significantly greater in DD than TR children. Ocular motor tracking, assessed by an infra-red limbal eye tracker while reading text, was most clearly associated with the visual symptoms, but only within the DD group. Vision-related symptom surveys followed by a comprehensive eye examination with detailed evaluation of sensorimotor functioning for those who report a high prevalence of symptoms may be clinically relevant for children with DD.
