Preventable vision loss in children with Coats disease

PurposeTo describe the prevalence and risk factors associated with amblyogenic refractive error in children with Coats disease. MethodsThe medical records of children (<18 years of age) with unilateral Coats disease treated at a single tertiary care center were retrospectively reviewed. Data collected included patient demographics, ocular examinations, and treatments. Outcomes included the prevalence and factors associated with amblyogenic refractive error. ResultsA total of 50 children (82% male) were included; of these, 37 (74%) had refractive data to review. The median age at presentation was 5 years (IQR, 2-10). The Coats disease classification was stage 1 in 1 (2%), stage 2 in 29 (58%), and stage 3 or greater in 20 (40%). Most children (76%) had at least one visit with a pediatric specialist; the rest were only seen by a retina specialist. Among patients with refractive data, amblyogenic refractive error was identified in 46%. Glasses were prescribed to 50% of children. Children diagnosed at an earlier age had increased odds of amblyogenic refractive error (OR = 0.72; 95% CI, 0.57-0.91; P = 0.006) than those diagnosed at an older age. ConclusionsOur results suggest that amblyogenic refractive error is prevalent among children with Coats disease, and refractions are not always performed. There is a need to coordinate care between pediatric and retina specialists caring for children with Coats disease to ensure timely diagnosis of amblyogenic refractive error to optimize visual outcomes in this population.

MFRP variations cause nanophthalmos in five Chinese families with distinct phenotypic diversity.

Nanophthalmos is a congenital ocular structural anomaly that can cause significant visual loss in children. The early diagnosis and then taking appropriate clinical and surgical treatment remains a challenge for many ophthalmologists because of genetic and phenotypic heterogeneity. The objective of this study is to identify the genetic cause of nanophthalmos in the affected families and analyze the clinical phenotype of nanophthalmos with MFRP gene variation (Microphthalmia, isolated; OMIM#611040 and Nanophthalmos 2; OMIM#609549, respectively). Comprehensive ophthalmic examinations were performed on participants to confirm the phenotype. The genotype was identified using whole exome sequencing, and further verified the results among other family members by Sanger sequencing. The normal protein structure was constructed using Alphafold. Mutant proteins were visualized using pymol software. Pathogenicity of identified variant was determined by in silico analysis and the guidelines of American College of Medical Genetics and Genomics (ACMG). The relationship between genetic variants and clinical features was analyzed. Five nanophthalmos families were autosomal recessive, of which four families carried homozygous variants and one family had compound heterozygous variants in the MFRP gene. Both family one and family three carried the homozygous missense variant c.1486G>A (p.Glu496Lys) in the MFRP gene (Clinvar:SCV005060845), which is a novel variant and evaluated as likely pathogenic according to the ACMG guidelines and in silico analysis. The proband of family one presented papilloedema in both eyes, irregular borders, thickened retinas at the posterior pole, tortuous and dilated retinal vessels, and indistinguishable arteries and veins, while the proband of family three presented uveal effusion syndrome-like changes in the right eye. In families one and 3, despite carrying the same gene variant, the probands had completely different clinical phenotypes. The homozygous nonsense variant c.271C>T (p.Gln91Ter) (Clinvar:SCV005060846) of the MFRP gene was detected in family 2, presenting shallow anterior chamber in both eyes, pigmentation of peripheral retina 360° from the equator to the serrated rim showing a clear demarcation from the normal retina in the form of strips. Family four proband carried the homozygous missense variant c.1411G>A (p.Val471Met) in the MFRP gene (Clinvar:SCV005060847), family five proband carried compound heterozygous missense variants c.1486G>A (p.Glu496Lys) and c.602G>T (p.Arg201Leu) in the MFRP gene (Clinvar:SCV005060848), which is a novel variant and evaluated as likely pathogenic according to the ACMG guidelines and in silico analysis, and they all presented clinically with binocular angle-closure glaucoma, family four also had retinal vein occlusion in the right eye during the follow-up. In this study, pathogenic variants of the MFRP gene were detected in five nanophthalmos families, including two novel variants. It also revealed a distinct phenotypic diversity among five probands harboring variants in the MFRP gene. Our findings extend the phenotype associated with MFRP variants and is helpful for ophthalmologists in early diagnosis and making effective treatment and rehabilitation strategies.

A novel base substitution mutation of the CRYBA2 gene is associated with autosomal dominant congenital cataract

Congenital cataract is one of the leading causes of vision loss in children, and a large proportion of cases are related to genetics. In a Chinese family, we reported a new missense mutation in CRYBA2 (c.223T>C: p.Tyr75His), which can cause autosomal dominant congenital bilateral cataract. We collected blood samples from family members (mother and two sons) and extracted DNA. Through whole-exome sequencing, we discovered a novel unreported mutation. According to relevant ACMG guidelines, this mutation was determined to be a variant of unknown clinical significance. This article further expands the site information on the CRYBA2 mutations.

Pattern of Refractive Error among Amblyopic Children at tertiary referral hospital of Ahmedabad, Gujarat.

Introduction: Amblyopia is one of the common causes of preventable uniocular or binocular vision loss in children. Timely diagnosis and management of amblyopia is crucial. If corrective measures are not taken in time it becomes permanent. Aim: To study the various types of refractive errors in amblyopic children aged 5-18 years in tertiary eye hospital. Materials and Methods: Retrospective cross –sectional study was carried out in the tertiary eye care hospital. All the children attending the ophthalmology OPD during January2021 to January 2023 were enrolled. All underwent detailed ophthalmic evaluation. After post mydriatic test, children with difference of two lines or more in visual acuity on Snellen chart were taken and detailed ophthalmic evaluation done. Results: The prevalence of amblyopia was 6.2% (n=48) with male dominant of 62.5% (n=30), while female was 37.5% (n=18). In types of Amblyopia, most common was simple Hypermetropic of 42% (n=20) followed by simple myopic and hypertropic Astigmatism 19% (n=9) in each. The Anisometropia Amblyopia was in 12% (n=6), while myopic astigmatism in 8%(n=4). The 69%(n=33) was binocular while 31% (n=15) was uniocular amblyopia. Conclusion: The Refractive errors are treatable and preventable cause of amblyopia. Timely diagnosis and proper treatments like spectacles, contact lenses, patching and active vision exercises, we can treat Amblyopia and prevent the psychosocial, economical loss in adult life. Keywords: Myopia, Hypermetropia, Anisometropia, Astigmatism

Vision Loss in Children from Immigrant and Nonimmigrant Households: Evidence from the National Survey of Children's Health 2018-2020.

The aim of this study was to determine whether immigrant generation is associated with caregiver-reported vision loss in children adjusting for sociodemographic characteristics. Nationally representative data from the National Survey of Children's Health (2018-2020) was used. The primary exposure was immigrant generation defined as: first (child and all reported parents were born outside the United States); second (child was born in the United States and at least one parent was born outside the United States); third or higher (all parents in the household were born in the United States). The main outcome was caregiver-reported vision loss in child. Adjusted odds ratios (aOR) and 95% confidence intervals were computed based on immigration generation. The study sample included 84,860 US children aged 3-17 years. First generation children had higher adjusted odds of caregiver-reported vision loss (aOR 2.30; 95% CI 1.21, 4.35) than third or higher generation children after adjusting for demographic characteristics and social determinants of health. For Hispanic families, first generation (aOR 2.99; 95% CI 1.34, 6.66), and second-generation children (aOR 1.70; 95% CI 1.06, 2.74) had a higher adjusted odds of vision loss compared with third or higher generation children. Even when adjusting for sociodemographic characteristics, first generation children had greater odds of vision loss, especially in Hispanic households, than third generation children. Immigration generation should be treated as an independent risk factor for vision loss for children and is a social determinant of eye health.

Random Allelic Expression in Inherited Retinal Disease Genes.

Inherited retinal diseases (IRDs) are a significant contributor to visual loss in children and young adults, falling second only to diabetic retinopathy. Understanding the pathogenic mechanisms of IRDs remains paramount. Some autosomal genes exhibit random allelic expression (RAE), similar to X-chromosome inactivation. This study identifies RAE genes in IRDs. Genes in the Retinal Information Network were cross-referenced with the recent literature to identify expression profiles, RAE, or biallelic expression (BAE). Loss-of-function intolerance (LOFI) was determined by cross-referencing the existing literature. Molecular and biological pathways that are significantly enriched were evaluated using gene ontology. A total of 184 IRD-causing genes were evaluated. Of these, 31 (16.8%) genes exhibited RAE. LOFI was exhibited in 6/31 (19.4%) of the RAE genes and 18/153 (11.8%) of the BAE genes. Brain tissue exhibited BAE in 107/128 (83.6%) genes for both sexes. The molecular pathways significantly enriched among BAE genes were photoreceptor activity, tubulin binding, and nucleotide/ribonucleotide binding. The biologic pathways significantly enriched for RAE genes were equilibrioception, parallel actin filament bundle assembly, photoreceptor cell outer segment organization, and protein depalmitoylation. Allele-specific expression may be a mechanism underlying IRD phenotypic variability, with clonal populations of embryologic precursor cells exhibiting RAE. Brain tissue preferentially exhibited BAE, possibly due to selective pressures against RAE. Pathways critical for cellular and visual function were enriched in BAE, which may offer a survival benefit.

Advancing retinoblastoma detection based on binary arithmetic optimization and integrated features

Retinoblastoma, the most prevalent pediatric intraocular malignancy, can cause vision loss in children and adults worldwide. Adults may develop uveal melanoma. It is a hazardous tumor that can expand swiftly and destroy the eye and surrounding tissue. Thus, early retinoblastoma screening in children is essential. This work isolated retinal tumor cells, which is its main contribution. Tumors were also staged and subtyped. The methods let ophthalmologists discover and forecast retinoblastoma malignancy early. The approach may prevent blindness in infants and adults. Experts in ophthalmology now have more tools because of their disposal and the revolution in deep learning techniques. There are three stages to the suggested approach, and they are pre-processing, segmenting, and classification. The tumor is isolated and labeled on the base picture using various image processing techniques in this approach. Median filtering is initially used to smooth the pictures. The suggested method’s unique selling point is the incorporation of fused features, which result from combining those produced using deep learning models (DL) such as EfficientNet and CNN with those obtained by more conventional handmade feature extraction methods. Feature selection (FS) is carried out to enhance the performance of the suggested system further. Here, we present BAOA-S and BAOA-V, two binary variations of the newly introduced Arithmetic Optimization Algorithm (AOA), to perform feature selection. The malignancy and the tumor cells are categorized once they have been segmented. The suggested optimization method enhances the algorithm’s parameters, making it well-suited to multimodal pictures taken with varying illness configurations. The proposed system raises the methods’ accuracy, sensitivity, and specificity to 100, 99, and 99 percent, respectively. The proposed method is the most effective option and a viable alternative to existing solutions in the market.

Central retinal artery occlusion following pediatric blunt ocular trauma.

To analyze the clinical profile, presentation, possible pathophysiology, and outcomes of central retinal artery occlusion (CRAO) following blunt trauma in pediatric subjects. The medical charts of subjects aged 18 years or less with a diagnosis of CRAO following blunt ocular trauma were analyzed retrospectively for demography, details of the trauma, ocular findings, additional imaging reports if any, and final outcome. A Medline search was done (key words like central retinal artery occlusion, blunt trauma, children, pediatric subjects, and adolescents) to gather information available in the literature on the subject. A total of 11 patients (11 eyes), mean age of 14.3 ± 3.4 years, and 100% male preponderance, with an average time duration from trauma to presentation to the hospital of 8.1 days were included. Visual acuity ranged from no light perception (four eyes) to finger count at a 1 m distance. Intraocular pressure was raised in three patients, of which two were suffering from sickle cell disease. In two eyes, the CRAO coexisted with optic nerve avulsion and the cilioretinal artery was spared. Disk pallor was seen in six eyes as early as 12 days from the trauma. None of the cases revealed any bony fracture in the CT scan. CRAO was observed to be an important primary or contributory cause of visual loss in children following blunt trauma, reflex vasospasm being the most common etiology. Early onset disk pallor could suggest an underlying vascular compromise of both retinal and optic disk circulation in addition to direct disk damage.

Five novel dysfunctional variants in the TSPAN12 gene in familial exudative vitreoretinopathy

Familial exudative vitreoretinopathy (FEVR) is an inheritable vitreoretinal disease characterized by incomplete retinal vascular development, which often leads to multiple retinal complications and causes severe vision loss in children. We reported the TSPAN12 variants' frequency in a cohort of FEVR and five novel TSPAN12 variants and related clinical features in six Chinese families. Seven hundred thirty-four families’ genetic in-house data were reviewed. Whole-exome sequencing (WES) was performed in all probands; Sanger sequencing was conducted in the family members. Five novel variants from six families were noted, and clinical data were collected. Luciferase assays were applied to test the activity of the Norrin/β-catenin signal caused by the mutant TSPAN12 genes. The frequency of TSPAN12 variants in FEVR is 8.79% (50/569). Five novel variants in TSPAN12 were identified in six families, including two missense variants, c.476G > A(p.Cys159Tyr) and c.81T > G(p.Ser27Arg), two frameshift variants, c.628_629insA(p.Met210Asnfs*42) and c.251delG(p.Gly84Glufs*3) and one nonsense, c.352G > T(p.Glu118*). Low vision, high myopia, nystagmus, and leukocoria are the common symptom at the first presentation. All variants were also predicted as pathogenic in silico. Moreover, the luciferase assay demonstrated that all variants caused severely compromised Norrin/β-catenin signaling activity. In conclusion, the frequency of TSPAN12 variants in FEVR was 8.79% in our cohort. Five novel variants of TSPAN12 were identified. Moreover, we demonstrated the dysfunction of mutant variants via the downregulation of Norrin/β-catenin signaling. These findings expanded the genetic and clinical spectrum of FEVR with TSPAN12 variants.

Subhyaloid hemorrhage in Evans Syndrome.

Evans syndrome is a rare disorder characterized by autoimmune hemolytic anemia and immune thrombocytopenia. We report the first case of ophthalmic involvement in a pediatric patient with Evans syndrome, in which painless vision loss was the presenting symptom. A 15-year-old female presented with acute painless loss of vision in her right eye and was found to have bilateral subhyaloid hemorrhages. She was treated with intravenous steroids and transitioned to hydroxychloroquine. Her retinal hemorrhages resolved and her vision improved. Nontraumatic subhyaloid hemorrhage is a rare cause of vision loss in children. Evans syndrome should be considered in the differential diagnosis of such patients when hematologic abnormalities are present.

Cortical visual impairment at birth can be improved rapidly by vision training in adulthood: A case study.

Cortical visual impairment (CVI) is a severe loss of visual function caused by damage to the visual cortex or its afferents, often as a consequence of hypoxic insults during birth. It is one of the leading causes of vision loss in children, and it is most often permanent. Several studies have demonstrated limited vision restoration in adults who trained on well-controlled psychophysical tasks, after acquiring CVI late in life. Other studies have shown improvements in children who underwent vision training. However, little is known about the prospects for the large number of patients who acquired CVI at birth but received no formal therapy as children. We, therefore, conducted a proof-of-principle study in one CVI patient long after the onset of cortical damage (age 18), to test the training speed, efficacy and generalizability of vision rehabilitation using protocols that had previously proven successful in adults. The patient trained at home and in the laboratory, on a psychophysical task that required discrimination of complex motion stimuli presented in the blind field. Visual function was assessed before and after training, using perimetric measures, as well as a battery of psychophysical tests. The patient showed remarkably rapid improvements on the training task, with performance going from chance to 80% correct over the span of 11 sessions. With further training, improved vision was found for untrained stimuli and for perimetric measures of visual sensitivity. Some, but not all, of these performance gains were retained upon retesting after one year. These results suggest that existing vision rehabilitation programs can be highly effective in adult patients who acquired CVI at a young age. Validation with a large sample size is critical, and future work should also focus on improving the usability and accessibility of these programs for younger patients.

Structural and functional alterations in the brains of patients with anisometropic and strabismic amblyopia: a systematic review of magnetic resonance imaging studies.

Amblyopia is the most common cause of vision loss in children and can persist into adulthood in the absence of effective intervention. Previous clinical and neuroimaging studies have suggested that the neural mechanisms underlying strabismic amblyopia and anisometropic amblyopia may be different. Therefore, we performed a systematic review of magnetic resonance imaging studies investigating brain alterations in patients with these two subtypes of amblyopia; this study is registered with PROSPERO (registration ID: CRD42022349191). We searched three online databases (PubMed, EMBASE, and Web of Science) from inception to April 1, 2022; 39 studies with 633 patients (324 patients with anisometropic amblyopia and 309 patients with strabismic amblyopia) and 580 healthy controls met the inclusion criteria (e.g., case-control designed, peer-reviewed articles) and were included in this review. These studies highlighted that both strabismic amblyopia and anisometropic amblyopia patients showed reduced activation and distorted topological cortical activated maps in the striate and extrastriate cortices during task-based functional magnetic resonance imaging with spatial-frequency stimulus and retinotopic representations, respectively; these may have arisen from abnormal visual experiences. Compensations for amblyopia that are reflected in enhanced spontaneous brain function have been reported in the early visual cortices in the resting state, as well as reduced functional connectivity in the dorsal pathway and structural connections in the ventral pathway in both anisometropic amblyopia and strabismic amblyopia patients. The shared dysfunction of anisometropic amblyopia and strabismic amblyopia patients, relative to controls, is also characterized by reduced spontaneous brain activity in the oculomotor cortex, mainly involving the frontal and parietal eye fields and the cerebellum; this may underlie the neural mechanisms of fixation instability and anomalous saccades in amblyopia. With regards to specific alterations of the two forms of amblyopia, anisometropic amblyopia patients suffer more microstructural impairments in the precortical pathway than strabismic amblyopia patients, as reflected by diffusion tensor imaging, and more significant dysfunction and structural loss in the ventral pathway. Strabismic amblyopia patients experience more attenuation of activation in the extrastriate cortex than in the striate cortex when compared to anisometropic amblyopia patients. Finally, brain structural magnetic resonance imaging alterations tend to be lateralized in the adult anisometropic amblyopia patients, and the patterns of brain alterations are more limited in amblyopic adults than in children. In conclusion, magnetic resonance imaging studies provide important insights into the brain alterations underlying the pathophysiology of amblyopia and demonstrate common and specific alterations in anisometropic amblyopia and strabismic amblyopia patients; these alterations may improve our understanding of the neural mechanisms underlying amblyopia.

Efficient correction of ABCA4 variants by CRISPR-Cas9 in hiPSCs derived from Stargardt disease patients

Inherited retinal dystrophies comprise a broad group of genetic eye diseases without effective treatment. Among them, Stargardt disease is the second most prevalent pathology. This pathology triggers progressive retinal degeneration and vision loss in children and adults. In recent years, the evolution of several genome editing technologies, such as the CRISPR-Cas9 system, has revolutionized disease modeling and personalized medicine. Human induced pluripotent stem cells also provide a valuable tool for invitro disease studies and therapeutic applications. Here, we show precise correction of two ABCA4 pathogenic variants in human induced pluripotent stem cells from two unrelated patients affected with Stargardt disease. Gene editing was achieved with no detectable off-target genomic alterations, demonstrating efficient ABCA4 gene correction without deleterious effects. These results will contribute to the development of emerging gene and cell therapies for inherited retinal dystrophies.

Global, Regional, and National Burdens of Blindness and Vision Loss in Children and Adolescents from 1990 to 2019: A Trend Analysis

To provide estimates for regional and national burdens of blindness and vision loss among children and adolescents between 1990 and 2019 by disease, age, and sociodemographic index (SDI). This was a retrospective demographic analysis based on aggregated data. This was a population-based study using 1990-2019 data on the burden of vision loss and blindness from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The burden of vision loss and blindness was evaluated in terms of case numbers, rates per 100 000 population, and average annual percentage changes (AAPCs) in prevalence rates and years lived with disability (YLDs). Globally, the rates of blindness and vision loss per 100 000 population decreased in all age groups between 1990 and 2019, with prevalence rates decreasing from 1091.4 (95% uncertainty interval [UI], 895.2-1326.1) to 1036.9 (95% UI, 847.8-1265.9, AAPC, -0.2) and YLDs decreasing from 44.5 (95% UI, 28.1-66.5) to 40.2 (95% UI, 25.1-60.7, AAPC, -0.4). Most of these reductions in prevalence rates (AAPC, -0.2, 95% confidence interval [CI], -0.2 to -0.1) and YLDs (AAPC, -0.2, 95% CI, -0.3 to -0.2) were due to decreases in refractive disorder. Notably, near-vision loss prevalence (AAPC, 0.3, 95% CI, 0.2-0.4) and YLDs (AAPC, 0.3, 95% CI, 0.2-0.4) substantially increased in all age groups. Children and adolescents in low- and low-middle SDI countries exhibited substantial decreases in the prevalence rates and YLDs of blindness and vision loss, but their counterparts in high- and middle-high SDI countries experienced a substantial increase in prevalence. Globally, efforts in the past 3 decades have substantially decreased the burdens of blindness and vision loss among children and adolescents. However, there is extensive variation according to the kind of impairment, age group, and country SDI.

Investigating functional visual loss in children and adolescents

Patients with a functional neurological disorder (FND) experience a lower psychological quality of life and have more mental health concerns. These patients deserve to be treated with a treatment that is evidence-based and proven effective. However, when we look children or adolescents with functional visual disorder (FVD; a subgroup of FND), we see that there is not much evidence for the effectiveness of their treatments. Possible reasons for this lack of evidence and the difficulties in studying children and adolescents with FVD are discussed in this article. This article concludes with possible ways of persuading children and adolescents with FVD in participating in research.

Recent Advances in Management of Amblyopia

Amblyopia is the most common cause of monocular vision loss in children. Global incidence is 3.7%. It may be due to early deprivation of vision or defocus in one eye, reflects an imbalance of input from the eyes to visual cortex .Not only monocular vision is reduced but binocular vision is also affected. Fellow Human brain is designed to allow both eyes to work together. If signals from one eye are blurred, brain blocks the visual input from that eye. In the visual pathway, the synapses are broken due to disuse of amblyopic eye. Along with visual coordination deficit, eye to hand and reading can be affected and selfperception may be diminished. A variety of amblyopia therapy options have been developed to treat amblyopia in children and adults. Amblyopia therapy options have traditionally been limited to penalization of non-amblyopic eye with either patching or medicinal penalization. Traditional approaches to diagnose and treatment have limited effectiveness, are uncomfortable for the patients and their families. Recent evidences shows that amblyopes possess binocular cortical mechanisms for both threshold and supra-threshold stimuli. Hence strategy may be based on binocular stimulation methods, aims to stimulate either eye leading to a concomitant improvement in monocular vision with reduction in suppression and strengthening of binocular vision.

Tecnics Eyhance Iol as a Solution for Anisometropic Amblyopia Cataract Patient: a Case Report

Background: Amblyopia affects 1-3% of the population, leading to irreversible vision loss in children and adults. Treatment options include refractive correction, occlusion therapy, and atropine penalization. Anisometropic amblyopia, caused by a difference in refractive status between the eyes, can be treated using contact lenses, glasses, ICL implantation, or cataract surgery with intraocular lens implantation. Tecnis Eyhance IOL is a superior solution, improving vision after eye surgery with a low incidence of halo, glare, or starburst. Objective: The aim is to present the case of a patient with anisometropic amblyopia, in whom Eyhance IOL was implanted in both eyes as a solution to refractive error and initial cataract due to intolerance for contact lenses. Case report: A 58-year-old female patient presented to our clinic complaining of blurry vision in her left eye that had persisted for a year. The patient reported intolerance to contact lenses and a history of amblyopia in her right eye. CDVA was 0.20 with -9.00/-1.50 x 25◦ in her right and 0.80 with +4.00 sphere correction in her left eye, while her CNVA was J9 with +2.50 and J1 with +2.50. Slit-lamp examination revealed early cataracts in both eyes, with otherwise normal findings. A dilated fundus examination showed vitreous liquefaction and myopic macula in the right eye but normal results in both eyes‘ posterior segments. The IOP was within normal limits, and the eye‘s axial length was measured. Considering the patient‘s intolerance to contact lenses, cataract surgery with intraocular lens implantation was deemed appropriate. Given the anisometropic amblyopia, the Eyhance lens was selected to optimize the patient‘s visual acuity. Following the procedure, the patient‘s visual acuity improved significantly, with her best CDVA at 0.35 in the right eye and 0.95 in the left eye. With +1.50 sphere correction, the CNVA was also enhanced, with the patient reading at J4 and J1 for her right and left eye, respectively. These improvements may have positively impacted the patient‘s quality of life and ability to perform daily activities. Conclusion: Anisometropic amblyopia in 58-year-old women was treated successfully with cataract surgery and implantation of Eyhance IOL.

Clinical Features of Infectious Uveitis in Children Referred to a Hospital-Based Eye Clinic in Italy.

Background and Objectives: To investigate the etiology, clinical features, ocular complications, and visual outcomes in children with infectious uveitis referred to a tertiary uveitis hospital-based service. Materials and Methods: Children with infectious uveitis were included in a retrospective cohort study. The data set was obtained after reviewing the medical records of pediatric patients with uveitis of different causes referred to our center during the period from 2009 to 2019. Clinical evaluations were performed at the time of diagnosis and the end of follow-up. Results: Uveitis of infectious origin was present in 57 (72 eyes) of 314 (18.1%) patients examined. The median age at presentation was 10.9 years (6.1-15.8), 52.6% of patients were female, and 47.4% were male. The main cause of infectious uveitis was viral (56.1% of cases), followed by Toxoplasma gondii infection (24.5%). The anatomical location of uveitis was posterior in 40.3%, anterior in 36.8%, panuveitis in 15.7%, and intermediate in 7% of cases. Ocular involvement was unilateral in 42 children (73.7%) and bilateral in 15 (26.3%) cases. The main causes of reduced visual acuity were cataract and maculopathy in 57.1% and 28.5% of cases, respectively. During the follow-up period, 75% of patients showed significant improvements in visual acuity. Conclusions: Specialist management in a tertiary referral eye care center facilitates early diagnosis and effective treatment of this serious cause of morbidity and vision loss in children.

Improving pediatric idiopathic intracranial hypertension care: a retrospective cohort study

To describe the clinical course and prognosis of pediatric idiopathic intracranial hypertension (IIH) and examine the preferred management setting.IIH is characterized by increased intracranial pressure and is often associated with headaches and visual complaints. IIH is a preventable cause of vision loss in children. Hence, a rapid diagnosis followed by prompt treatment and follow-up is essential. However, standardization of the management of IIH in the pediatric population is not well established. Computerized medical charts of all 82 pediatric (< 18 years) patients diagnosed with IIH between 2007 and 2018 in the metropolitan area of Jerusalem were reviewed. Comparison was made between children followed in a multidisciplinary clinic in tertiary centers and those followed elsewhere. Detailed demographic and clinical data, as well as data regarding the follow-up setting and clinical course of the disease, were collected and analyzed. Recurrent IIH-related hospital returns were selected as a measurable marker for the uncontrolled disease. Recurrent IIH-related hospital return rate was significantly lower and occurred later among children followed by multidisciplinary teams compared to individual experts. Follow-up in multidisciplinary clinics improve the quality of life, and financial burden and may prevent permanent visual impairment in children with IIH.
