Patterns of uveitis in children according to age: comparison of visual outcomes and complications in a tertiary center

Visual Impairment at Presentation in Pediatric Uveitis: A Multicentric Study in 477 Children Across Southern and Eastern India

OBJECTIVE

To evaluate visual impairment (VI) at presentation in pediatric uveitis cases in southern and eastern India.

METHODS

Retrospective analysis of 477 children across four tertiary centers (2015-2020). Best-documented visual acuity (ETDRS letters) in the better eye was used to categorize VI.

RESULTS

Mean age at presentation was 11 ± 3.7 years; 43.8% were females, and 64.8% bilateral. Of 205 patients with complete investigations, 32.7% were undifferentiated uveitis, 31.7% infectious, 25.7% juvenile idiopathic arthritis-associated uveitis, and 10.2% other non-infectious uveitis. At presentation, 79.0% had none to mild VI, 12.6% moderate VI, and 8.4% severe VI to blindness. On generalized estimating equations analysis for individual eyes, prior oral steroids and older age were risk factors, while female gender, prior topical corticosteroids and immunosuppressive therapy were protective against moderate and/or severe VI.

CONCLUSIONS

Over a fifth of pediatric uveitis cases present with moderate/severe VI, especially in older age or with prior oral corticosteroid therapy.

Clinical characteristics of pediatric noninfectious uveitis and risk factors for severe disease: a single-center study

OBJECTIVES

We aimed to present the demographic, clinical, laboratory, and treatment data of children with non-infectious uveitis and to evaluate the risk factors for the development of complications and the need for biological treatment.

METHOD

Patients diagnosed with non-infectious uveitis in childhood and followed up for at least 1 year were included in the study. Demographic data, including age, gender, age at diagnosis, uveitis in first-degree relatives, and rheumatologic diseases, were obtained retrospectively from medical records. The presence of complications or the need for biologic therapy was considered a composite outcome suggesting severe disease.

RESULTS

The study included 123 patients (female: n = 59, 48%). The mean age at diagnosis was 14.89 ± 4.86 years. Uveitis was symptomatic in 104 patients (84.6%). Approximately one-quarter of the patients had at least one rheumatic disease (n = 35, 28.5%), the most common being juvenile idiopathic arthritis. Thirty-three patients (26.8%) had anti-nuclear antibody positivity. Biologic agents were needed in 60 patients (48.8%). Complications developed in 14 patients (11.4%). Early age at disease onset (aOR, 0.875; 95% C.I. 0.795-0.965, p = 0.007) and female gender (aOR, 2.99; 95% C.I. 1.439-6.248, p = 0.003) were significantly associated with the need for biologic treatment, while Behçet's disease (BD) was strongly associated with uveitis-related complications (aOR, 14.133; 95% C.I. 2.765-72.231, p = 0.001).

CONCLUSION

We suggest that among pediatric patients with non-infectious uveitis, females, those with an early age of disease onset, and those with BD need to be closely monitored due to a significantly increased risk of severe disease. Key Points • Limited data exist on the clinical course of non-infectious uveitis in children and the associated risk factors for severe disease. • Our study reveals that nearly a quarter of pediatric patients with non-infectious uveitis also have a rheumatic disease. • Among pediatric patients diagnosed with non-infectious uveitis, we observed an increased risk of severe disease in those with an earlier onset age, in female patients, and in those diagnosed with Behçet's disease.

Communicating exploratory unsupervised machine learning analysis in age clustering for paediatric disease

BACKGROUND

Despite the increasing availability of electronic healthcare record (EHR) data and wide availability of plug-and-play machine learning (ML) Application Programming Interfaces, the adoption of data-driven decision-making within routine hospital workflows thus far, has remained limited. Through the lens of deriving clusters of diagnoses by age, this study investigated the type of ML analysis that can be performed using EHR data and how results could be communicated to lay stakeholders.

METHODS

Observational EHR data from a tertiary paediatric hospital, containing 61 522 unique patients and 3315 unique ICD-10 diagnosis codes was used, after preprocessing. K-means clustering was applied to identify age distributions of patient diagnoses. The final model was selected using quantitative metrics and expert assessment of the clinical validity of the clusters. Additionally, uncertainty over preprocessing decisions was analysed.

FINDINGS

Four age clusters of diseases were identified, broadly aligning to ages between: 0 and 1; 1 and 5; 5 and 13; 13 and 18. Diagnoses, within the clusters, aligned to existing knowledge regarding the propensity of presentation at different ages, and sequential clusters presented known disease progressions. The results validated similar methodologies within the literature. The impact of uncertainty induced by preprocessing decisions was large at the individual diagnoses but not at a population level. Strategies for mitigating, or communicating, this uncertainty were successfully demonstrated.

CONCLUSION

Unsupervised ML applied to EHR data identifies clinically relevant age distributions of diagnoses which can augment existing decision making. However, biases within healthcare datasets dramatically impact results if not appropriately mitigated or communicated.

Non-infectious uveitis referred for pediatric rheumatologic assessment and management: A Portuguese retrospective study

BACKGROUND

Pediatric uveitis poses challenges in diagnosis and treatment due to asymptomatic or oligosymptomatic presentations and high rates of intraocular complications.

OBJECTIVES

This study aimed to characterize clinical manifestations and treatment approaches of pediatric uveitis patients in a northern Portuguese tertiary hospital.

METHODOLOGY

A retrospective study was conducted involving 41 patients diagnosed with uveitis between 2006 and 2021. All individuals identified by the Opthalmology department were referred to Pediatric Rheumatology outpatient clinic. Demographic, clinical, treatment, and intraocular complications data were collected.

RESULTS

Of the patients, 78% had anterior uveitis, 17% had panuveitis, and 5% had intermediate uveitis. Uveitis associated with juvenile idiopathic arthritis (JIA) was the most common cause (43.9%), predominantly in the oligoarticular, anti-nuclear antibody-positive subgroup. Complications were identified in 80.5% of the patients. Uveitis associated with JIA was diagnosed earlier [5.0 years (3.0-10.5) vs. 9.0 years (5.5-14.0), P = .036], more frequently in asymptomatic patients (71% vs. 23%, P = .010), had a more insidious installation (71% vs. 17%, P = .004), and required more tumor necrosis factor (TNF) inhibitor treatment (70% vs. 39%, P = .027).

CONCLUSION

The high rates of intraocular complications and systemic pathology association highlight the need for a combined approach of ophthalmology and pediatric rheumatology in the diagnosis and treatment of pediatric uveitis.

Clinical profile and treatment outcomes in pediatric uveitis - A series from South India

PURPOSE

The purpose of the study was to look at the clinical spectrum, treatment options, and visual outcomes in a large cohort of pediatric uveitis from a tertiary eye care center in South India.

METHODS

This is a retrospective study carried out at a tertiary eye center in South India. Cases of pediatric uveitis between January 2012 and June 2022 were retrieved from the hospital's medical database. Uveitis was classified according to the Standardization of Uveitis Nomenclature criteria. Demographic details, clinical presentation, complications, medical and surgical management, and visual outcome were evaluated.

RESULTS

Two hundred and six eyes of 132 cases were included, with a median age of 12 years. The male to female ratio was 1:1. Bilaterality was seen in 63.1% of cases. The mean duration of uveitis was 11.5 ± 18.5 months, and the mean follow-up period was 20.5 ± 25.1 months. Noninfectious uveitis was seen in 70.45% cases. Most common etiology in the noninfectious group was idiopathic (27.3%), while in the infectious group, it was tuberculosis (TB; 14.4%). Immunomodulators were used in 43.9% and biologics in 10.9% of cases. Most common complications were cataract (25.24%) and posterior synechiae (21.35%). Surgical procedures were done in 12.62%. The mean visual acuity was 0.81 ± 1.14 log of minimum angle of resolution (logMAR) at presentation and 0.49 ± 0.87 logMAR at the end of the study ( P = 0.002).

CONCLUSION

Pediatric uveitis poses a challenge in comparison to adult uveitis. Our study highlights the need for early diagnosis and aggressive management to prevent sequelae. Multidisciplinary approach is a key in improving the overall visual prognosis.

Diagnosis and Treatment of Uveitis in Children: A Summary of the Latest Data from a 5-Year Literature Review (2018-2023)

Pediatric uveitis has a low incidence. It is very diverse in its presentation and is often the first sign of a severe systemic disease. The pediatric population poses a special therapeutic and diagnostic challenge due to the potentially adverse effects of therapeutic agents on the young body and difficult cooperation with the patient during the examination, as well as the increased risk of complications that can lead to severe disability. The most commonly diagnosed type of uveitis is non-infectious, with first-line therapy consisting of systemic corticosteroids followed by disease-modifying drugs (methotrexate (MTX), mycophenolate mofetil (MMF), and cyclosporin A (CsA)). In severe, refractory cases, biologic therapy is used. The authors reviewed the current literature on the etiology, diagnostic tools, and treatment of uveitis in the pediatric population covering the years 2018-2023, presenting current methods of modern diagnosis and treatment. The reason for writing this article was the need to update the knowledge on uveitis, driven by the increasing prevalence of autoimmune uveitis in the pediatric population. This trend presents significant challenges in diagnosing and treating the disease, as well as managing its complications. Correctly identifying the pathogenetic factor of uveitis can facilitate the diagnosis of the systemic disease underlying the ocular infection and enable the timely implementation of systemic treatment. Furthermore, the emergence of new diagnostic methods necessitates a revision and update of ophthalmic knowledge, essential for both ophthalmologists and other specialists involved in the treatment of uveitis.

Uveitis Profile in Children and Its Impact on Vision at Queen Rania Children's Hospital

AIM

The aim of this study was to explore the patterns of pediatric uveitis and the types of ocular complications of uveitis and to determine the possible risk factors associated with visual impairment.

METHOD

This was a cross-sectional study conducted at Queen Rania Children's Hospital between June 2020 and June 2023. All children diagnosed with uveitis were enrolled in the study. After collecting data from the patients and reviewing their medical records regarding age, gender, and past ocular and medical history, the patients were subjected to a detailed ophthalmic exam including best-corrected visual acuity (BCVA). Anterior segment exam using the slit lamp, intraocular pressure exam using Goldmann applanation tonometry, and posterior segment exam using 78 and 90 diopter Volk lenses were performed. Patients with other ocular diseases that affected visions not related to uveitis were excluded from the study.

RESULTS

A total of 82 children, accounting for 130 eyes, were enrolled in this study, with ages ranging from 2 to 16 years (mean age 10.5±4.3 years). Among them, 27 were males, constituting 32.9% of the participants. Unilateral uveitis was observed in 34 eyes, representing 26.2% of cases. The mean age of uveitis onset was 6.9±1.9 years, and the mean disease duration was 4.8±0.4 years. The majority of cases i.e. 90.8% (n = 74) were non-infectious, with 92.3% (n = 76) classified as non-granulomatous and 79.2% (n = 65) categorized as chronic. Anterior uveitis was the most prevalent site of inflammation in 70.8% of cases (n = 58), followed by panuveitis in 20.0% of cases (n = 16), intermediate uveitis in 6.2% of cases (n = 5), and posterior uveitis in 3.0% of cases (n = 2). The cause of uveitis could not be identified in 40.0% (n = 33) of cases. Juvenile idiopathic uveitis emerged as the most commonly known disorder associated with uveitis in 40.0% (n = 33) of cases. Complications were identified in 52.3% (n = 43) of cases, with posterior synechiae being the most prevalent; 26.9% (n = 22) demonstrated an improvement in BCVA, while 21.5% (n = 18) experienced a decline in BCVA relative to the initial assessment Conclusion: Pediatric uveitis tends to manifest as anterior, chronic, bilateral, and non-granulomatous. Higher frequencies of severe visual impairment are linked to panuveitis, infectious and granulomatous uveitis, early-onset, long-duration cases, and male gender. The use of biologics has a positive effect, significantly improving or preserving visual acuity.

Childhood Chronic Idiopathic Uveitis in a Multicentre International Cohort

IMPORTANCE

Idiopathic uveitis makes up around 50% of non-infectious uveitis but the clinical characteristics in children are poorly understood.

OBJECTIVE

To report the demographic, clinical characteristics, and outcomes of children with idiopathic non-infectious uveitis (iNIU) in a multicentric retrospective study.

RESULTS

There were 126 (61 female) children with iNIU. The median age at diagnosis was 9.3 years (3-16 years) . Uveitis was bilateral in 106 patients and anterior in 68.At onset,impaired visual acuity and blindness in the worse eye were reported, in 24.4% and 15.1% patients but at 3 years of follow-up, there was a significant improvement in visual acuity (mean 0.11 SD ±0.50 vs 0.42 SD ± 0.59 p < .001).

CONCLUSIONS AND RELEVANCE

There is a high rate of visual impairment at presentation in children with idiopathic uveitis. The majority of patients have a significant improvement in vision, but 1 in 6 had impaired vision or blindness in their worse eye at 3 years.

Demographic and Clinical Profile of Pediatric Uveitis in Delta Region, Egypt

PURPOSE

Pediatric uveitis poses unique challenges, characterized by difficulties in performing comprehensive examinations, potential delays in diagnosis, and a heightened risk of ocular complications. This study evaluate the etiologic and clinical characteristics of uveitis in children presenting to the Mansoura Ophthalmic Center, Mansoura, Egypt.

METHODS

A cross-sectional observational study was undertaken involving children diagnosed with uveitis attending the uveitis outpatient clinic at Mansoura University Ophthalmic Center. Comprehensive clinical evaluations were carried out, including detailed history taking and exhaustive ophthalmological examinations. Whenever deemed necessary, Spectral Domain Optical Coherence Tomography (OCT) and Fluorescein Fundus Angiography (FFA) were utilized to secure retinal images. An extensive systemic evaluation was also conducted to discern the diverse causes of uveitis among the participants.

RESULTS

The cohort comprised 63 children, impacting 97 eyes. Bilateral involvement was seen in 54% of cases, with a male predominance of 58.7%. The predominant etiologies of uveitis were presumed trematode-induced (36.7%), Juvenile Idiopathic Arthritis (JIA) accounting for 28.6%, and in 12.7% of cases, the cause remained undetermined. Anterior uveitis emerged as the primary presentation in 79.4% of cases. Regarding visual loss, cataract was the leading cause at 56.4%, followed by vitritis at 38.4%, and macular edema at 20.5%.

CONCLUSION

Anterior uveitis was the most frequent presentation in our pediatric cohort. Despite the challenges, the majority of children with uveitis exhibited no significant visual impairment, with most causes of visual loss being reversible.

Monitoring compliance to topical therapy in children and young people with uveitis

BACKGROUND/OBJECTIVES

Uveitis in children and young people (CYP) is a rare but potentially debilitating condition. Steroid eye drops are the first step in treatment and poor compliance may result in vision-threatening complications. This study aims to measure compliance with prescribed eye drops prospectively in a child-specific manner.

SUBJECTS/METHODS

Patients aged 0-18 years attending a tertiary paediatric uveitis clinic using steroid drops were recruited. Both the CYP, and person with parental responsibility (PPR) completed questionnaires about compliance. A subgroup had bottles of Prednisolone 1% drops dispensed and weighed at the first appointment and reweighed at follow-up. The weight reduction was compared with expected weight change over the interval.

RESULTS

The study was completed by 42 patients of the 50 patients recruited. Thirty-one CYP and their respective PPR completed both questionnaires, 11 completed only one questionnaire (9 CYP, 2 PPR). Drop errors for all eye drops were reported more than "once a week" by 13/39 CYP (33.3%, 95% CI: 19.1%-50.2% of respondents), and 3/31 PPR (9.7%, CI: 19.1%-50.2% of respondents). Many PPR could not recall prescribed drop frequency (n = 13/31, 40.6%, CI: 23.7%-59.4% of respondents). Twelve patients had bottles weighed and returned. Insufficient weight reduction was found in 9 (75%, CI: 42.8%-94.5%). Within the eye drop weighing subgroup three participants (25%, CI: 5.5%-57.2%) used <50% the expected weight of drops.

CONCLUSIONS

This study demonstrated poor eye drop compliance in CYP with uveitis. Self-reported compliance was unreliable in this population. Worryingly, some patients miss more than 50% of drops and may suffer sub-optimal disease control.

Epidemiology of Pediatric Uveitis

Uveitis is uncommon in children and its diagnosis and treatment are challenging. Little is known of the epidemiology of pediatric uveitis. Indeed, population-based studies in the literature are rare. However, there are many tertiary referral center reports that describe the patterns of uveitis in childhood, although few are from developed countries, and their comparison presents some issues. Anterior uveitis is the most frequent entity worldwide, especially in Western countries, where juvenile idiopathic arthritis is diffuse. Most cases of intermediate uveitis do not show any association with infectious or noninfectious systemic diseases. In low- and middle-income countries, posterior uveitis and panuveitis are prevalent due to the higher rates of infectious etiologies and systemic diseases such as Behçet disease and Vogt-Koyanagi-Harada disease. In recent decades, idiopathic uveitis rate has decreased thanks to diagnostic improvements.

Pediatric Uveitis in Turkey: The National Registry Report II

PURPOSE

To report demographic and clinical profiles of children with uveitis in theTurkishpopulation.

METHODS

The data of the pediatric uveitis cases in the nation wide uveitis database were analyzed.

RESULTS

The study included 697 eyes of 442 patients with a meanage of 10.8 ± 3.8 years. There were 333 patients (75.3%) with non-infectious uveitis and 69 patients (15.6%) with infectious uveitis. Pars planitis (20.1%) was leading clinical form followed by idiopathic cases with uveitis other than pars planitis (18.8%), juvenile idiopathic arthritis(JIA) related uveitis (12.4%), Behçet uveitis (9.3%) and toxoplasma retinochoroiditis (7.9%). Ocular involvement was unilateral in 187 patients (42.3%) and bilateral in 255 patients (57.7%). The most common anatomiclocation of uveitis was anterior uveitis (39.1%), followed by intermediate uveitis (29.4%), panuveitis (16.1%) and posterior uveitis (15.4%).

CONCLUSION

The most common systemic association was JIA in the younger children and Behçet disease in the older children.

Encouraging visual outcomes in children with idiopathic and JIA associated uveitis: a population-based study

BACKGROUND

Pediatric uveitis is typically asymptomatic and may become chronic affecting ocular structures and vision. We evaluated visual outcomes, clinical features, medication, and uveitis activity in children with either idiopathic uveitis (idio-U) or juvenile idiopathic arthritis associated uveitis (JIA-U).

METHODS

A longitudinal, population-based cohort study of children with uveitis in 2008-2017. The data included parameters for age, gender, age at diagnosis, laterality, chronicity, anatomical distribution, etiology, systemic association, uveitis activity, medication, and visual outcomes.

RESULTS

A total of 119 patients aged < 16 years with uveitis were included. Uveitis was idio-U in 23% and associated with JIA in 77% of cases. 37% of the patients in the idio-U group and 65% in the JIA-U were girls (p = 0.014). The mean age at first uveitis was 10.0 (SD 3.4) years in idio-U and 5.5 (SD 3.3) years in JIA-U (p < 0.001). Anterior location of uveitis was noted in 74% in idio-U and 99% in JIA-U (p < 0.001). Mostly, uveitis was chronic (59% in idio-U and 75% in JIA-U) and bilateral (56% in idio-U and 64% in JIA-U). Topical corticosteroids were initially used by 89% and 100%, systemic corticosteroids by 30% and 27% in some extent during the follow-up, disease-modifying antirheumatic drugs (DMARDs) by 33% and 85% (p < 0.001) of the patients in idio-U and JIA-U, respectively. Biologic disease-modifying antirheumatic drugs (bDMARDs) were more common in JIA-U (55% vs. 15% in idio-U, respectively, p < 0.001). Most patients had normal visual acuity (Snellen > 0.8, [6/7.5]) in the affected eye and bilaterally in 85% idio-U and 70% JIA-U. Only 5 patients (4%) had visual impairment in one, but none in both eyes. Uveitis activity by SUN classification was 0 + in 81% and 72%, 0.5 + in 19% and 25%, and 1 + in 0% and 3% in the idio-U and JIA-U, respectively.

CONCLUSIONS

Children with uveitis have good visual acuity and a low rate for visual impairment. In addition, modern treatment with DMARDs and bDMARDs seems to save vision.

Visual outcome in pediatric uveitis: A retrospective data review in 277 children

Purpose

This study aimed to describe visual outcomes in cases of pediatric uveitis in an Indian population and to analyze various factors affecting these outcomes.

Methods

Single-center, retrospective chart review of 277 cases of uveitis in patients under the age of 18 years. Variables assessed included age and sex distribution, anatomical location of uveitis, systemic associations, complications, and various treatment strategies used, including long-term immunomodulation and surgical management of complications if required. The main outcome was the final visual acuity.

Results

At the final visit, 51.5% of the eyes showed improvement in the final visual acuity, while vision remained stable in 28.7% and 19.7% of the eyes showed worsening of vision at the final follow-up. A total of 19.4% of patients were blind in at least one eye at the final visit, and 16 patients (5.77%) remained bilaterally blind at the final follow-up. The presence of cataract (p = 0), posterior uveitis (p = 0.005), and retinal detachment (p = 0.014) were the most significant risk factors for predicting worse visual outcomes. More than half (65.7%) of patients reported a complication at some point in their follow-up, and the most common complication was cataract. In total, 50.9% of patients required long-term immunomodulatory therapy.

Conclusion

Pediatric uveitis remains a challenging condition to treat and follow-up, and the visual outcome remains guarded for most patients.

Uveitis in children: Epidemiological, clinical and prognostic characteristics

PURPOSE

The purpose of this study is to describe the characteristics and prognostic factors of pediatric uveitis in a French university referral hospital.

METHODS

We performed a retrospective study of all cases of all pediatric uveitis seen at our institution over a 7-year period.

RESULTS

A total of 141 eyes of 86 children were included. The mean age was 10.7 years, and 61.6% were girls. The uveitis was bilateral in 64.0% of cases. Anterior uveitis (41.0%) and intermediate uveitis (32.0%) were the most frequent forms. The most frequent etiologies were idiopathic (27.9%), juvenile idiopathic arthritis (25.6%) and pars planitis (18.6%). During the follow-up period, systemic corticosteroids were received by 43.0% of children, immunosuppressive drugs by 31.4% and biological agents by 18.6%. At the final examination, complications were present in 67.0% of patients: 18.0% had cataracts, and 11.3% had intraocular hypertension. Posterior synechiae were present in 27.6% of eyes, optic disc edema in 10.5% and macular edema in 16.2%. At the last visit, visual acuity was better than 20/200 in 97.0% of cases. The presence of band keratopathy, cataract or glaucoma was an independent predictor of impaired visual outcomes at follow-up.

CONCLUSION

Juvenile idiopathic arthritis is one of the most frequent and severe pediatric uveitides. Close monitoring and early treatment could prevent complications.

Clinical Utility of 18F-FDG PET/CT in the Work-up of Children with Uveitis

PURPOSE

To evaluate ¹⁸F-fluorodeoxyglucose Positron Emission Tomography/ultra low dose Computed Tomography (¹⁸F-FDG PET/ ULD CT) in the work-up of pediatric uveitis.

METHODS

Retrospective study of 12 children followed for uveitis who underwent whole body ¹⁸F-FDG PET/ULD CT between 2011 and 2019.

RESULTS

The average age of the patients was 11 years. A total of 100% of patients presented with bilateral uveitis, 50% had panuveitis and 92% had various choroidal involvement. Relevant information for diagnosis was provided in four patients. 5/12 had an abnormal 18F-FDG uptake. Of these, three patients had pathognomonic images of active granulomatous diseases. Three patients underwent PET CT-guided biopsies of which two were positive for sarcoidosis.

CONCLUSION

¹⁸F-FDG PET/CT provided important information for final diagnosis in approximately 30% (4/12) of pediatric patients with bilateral uveitis. Whole body FDG PET/ULD CT can contribute to the final diagnosis thanks to pathognomonic image of active granulomatous disease and/or by indicating metabolically active site of biopsy that would not be visualized in thorax CT.

Pediatric Noninfectious Uveitis in a Tertiary Referral Center in Jordan: Clinical Spectrum and Immunomodulatory Treatment

Objectives

This study aims to describe the clinical, etiological, and treatment features of noninfectious uveitis in Jordanian children in a single center.

Methods

A retrospective, observational analysis of medical records of pediatric patients who were diagnosed with noninfectious uveitis from 2015 to 2020 at pediatric rheumatology and ophthalmology clinics at Queen Rania Children’s Hospital, Amman, Jordan, was conducted. All patients were below 14 years of age at diagnosis. The collected data included age at diagnosis, anatomical location of uveitis, laterality, associated systemic disease, and used medications.

Results

Overall, 96 patients were included in this cohort (41 males and 55 females), with a mean age at diagnosis of 8.4±2.4 years. Anterior uveitis (44.8%) was the commonest anatomical location. Based on laterality, bilateral uveitis was reported in 59.3% of all patients. Idiopathic uveitis (46.9%) and juvenile idiopathic arthritis-associated uveitis (JIAU) (35.5%) were the most common diagnoses. Of the children with idiopathic uveitis, 47% had panuveitis, while 61.7% of the children with JIAU had chronic anterior uveitis. Posterior synechiae were the most common complication (12.5%). Patients with refractory uveitis received infliximab (29.1%) and adalimumab (4.1%).

Conclusion

To the best of our knowledge, this is the first report on noninfectious uveitis in Jordanian children. Compared with other regional and international published reports, JIAU and idiopathic uveitis were the most common diagnoses. To obtain more details on noninfectious uveitis characteristics, a population-based rather than a single-center study is needed in Jordan.

Demographic and clinical features of pediatric uveitis and scleritis at a tertiary referral center in China

Background

To analyse demographic, clinical features, treatment and therapeutic outcomes of pediatric uveitis and scleritis patients.

Subjects

The clinical records of pediatric uveitis and scleritis cases between January 2012 and December 2020 at a tertiary uveitis service center in Tianjin Medical University Eye Hospital (TMUEH) were reviewed.

Results

In total, 209 patients (337 eyes) were included, 49.3% were male. The median onset age was 9.0 (IQR, 7.0–12.0) years. Chronic uveitis and scleritis accounted for 86.1%. Panuveitis (29.2%), anterior uveitis(29.2%), and intermediate uveitis (22.0%) were the most common presentations. The most common diagnoses were idiopathic (71.3%), JIA (8.1%), and infectious uveitis (4.8%). At baseline, 40.7% patients received oral corticosteroid therapy; during follow-up, corticosteroids (66.0%), disease-modifying antirheumatic drugs (61.2%), and biologic agents (35.4%) were the mainstay. Posterior synechia (26.1%) and cataracts (25.5%) were the most common complications. In acute cases, the median best corrected visual acuity (BCVA) was 0.99 (IQR, 0.5–1.0) at baseline and 0 (IQR, 0–0) at last follow-up; in chronic cases, the median BCVA improved from 1.09 (IQR, 0.5–2.0) to 0.27 (IQR, 0–0.5), with anterior chamber cell grade significantly declining. Ten eyes underwent cataract surgery during regular follow-up and achieved satisfactory long-term visual outcomes and decreased burden of immunosuppressants. The incidence of steroid-induced ocular hypertension was 41.0%, and children with frequent instillation of eyedrops were at high risk.

Conclusions

Most cases were of chronic uveitis and scleritis requiring long-term systemic immunosuppressive therapies in pediatric uveitis and scleritis in China. Good management of complications is important for long-term prognosis.

Chronic Uveitis in Children

OBJECTIVE

To describe the experience of managing chronic childhood uveitis from a tertiary care center in India.

METHODS

All children diagnosed as chronic uveitis between January 2005 and December 2012 and on follow-up in Pediatric Rheumatology Clinic and Uveitis Clinic, were eligible for enrollment. Information regarding demographics, type of uveitis, treatment, complications, and surgical procedures was obtained from clinic records. All the enrolled patients were assessed for outcome prospectively and underwent a detailed ophthalmological examination to document visual acuity, refraction, intraocular pressure (IOP), slit lamp examination, fundus examination, and vitreous haze findings.

RESULTS

Sixty-seven children with chronic uveitis were enrolled in the study. Anterior uveitis was the commonest type seen in 45 children. Juvenile idiopathic arthritis (JIA) was the commonest known etiology and diagnosis of uveitis was made during routine screening in a majority of the JIA patients. No cause could be identified in 43% patients. After a mean follow-up period of 3.95 ± 1.99 y, only 16% eyes were in remission and off therapy. Prolonged oral glucocorticoids were required, besides other immunosuppressants, to control inflammation in 50% patients. Ocular complications were seen in 87% cases with posterior synechiae, band-shaped keratopathy and cataracts being the commonest complications.

CONCLUSIONS

Among patients with chronic uveitis, 43% had no identifiable cause. JIA was the commonest known cause. Significant ocular complications were common. Even after a mean follow-up of 3.95 ± 1.99 y, a vast majority continued to need immunosuppression for control of disease activity.

Pediatric uveitis: A comprehensive review

Pediatric uveitis accounts for 5-10% of all uveitis. Uveitis in children differs from adult uveitis in that it is commonly asymptomatic and can become chronic and cause damage to ocular structures. The diagnosis might be delayed for multiple reasons, including the preverbal age and difficulties in examining young children. Pediatric uveitis may be infectious or noninfectious in etiology. The etiology of noninfectious uveitis is presumed to be autoimmune or autoinflammatory. The most common causes of uveitis in this age group are idiopathic and juvenile idiopathic arthritis-associated uveitis. The stepladder approach for the treatment of pediatric uveitis is based on expert opinion and algorithms proposed by multidisciplinary panels. Uveitis morbidities in pediatric patients include cataract, glaucoma, and amblyopia. Pediatric patients with uveitis should be frequently examined until remission is achieved. Once in remission, the interval between follow-up visits can be extended; however, it is recommended that even after remission the child should be seen every 8-12 weeks depending on the history of uveitis and the medications used. Close follow up is also necessary as uveitis can flare up during immunomodulatory therapy. It is crucial to measure the impact of uveitis, its treatment, and its complications on the child and the child's family. Visual acuity can be considered as an acceptable criterion for assessing visual function. Additionally, the number of cells in the anterior chamber can be a measure of disease activity. We review different aspects of pediatric uveitis. We discuss the mechanisms of noninfectious uveitis, including autoimmune and autoinflammatory etiologies, and the risks of developing uveitis in children with systemic rheumatologic diseases. We address the risk factors for developing morbidities, the Standardization of Uveitis Nomenclature (SUN) criteria for timing and anatomical classifications, and describe a stepladder approach in the treatment of pediatric uveitis based on expert opinion and algorithms proposed by multi-disciplinary panels. In this review article, We describe the most common entities for each type of anatomical classification and complications of uveitis for the pediatric population. Additionally, we address monitoring of children with uveitis and evaluation of Quality of Life.

Cataract Surgery with or without Intraocular Lens Implantation in Pediatric Uveitis: A Systematic Review with Meta-Analyses

PURPOSE

To systematically review the results of comparative studies of modern cataract surgery in pediatric uveitis with or without intraocular lens (IOL) implantation and to perform comparative meta-analyses to compare visual acuity outcomes and complication rates.

METHODS

On 12 November 2020, we systematically searched the Cochrane Central, PubMed/MEDLINE, EMBASE, ClinicalTrials.gov, and all affiliated databases of the Web of Science. Two authors independently reviewed studies and extracted data. Studies were reviewed qualitatively in text and quantitatively with meta-analyses. Outcome measures were preoperative and postoperative best-corrected visual acuity (BCVA), inflammation control, and rates of postoperative complications.

RESULTS

Ten studies of 288 eyes were eligible for review of which the majority were eyes with juvenile idiopathic arthritis-associated uveitis. Summary estimates revealed that the BCVA was better in pseudophakic eyes vs. aphakic eyes (1-year postoperative: -0.23 logMAR, 95% CI: -0.43 to -0.03 logMAR, P=0.027; 5-year postoperative: -0.35 logMAR, 95% CI: -0.51 to -0.18 logMAR, P=0.000036). Pseudophakic eyes had more visual axis opacification (OR 6.76, 95% CI: 2.73 to 16.8, P=0.000036) and less hypotony (OR 0.19, 95% CI: 0.04 to 0.95, P=0.044).

CONCLUSIONS

In modern era cataract surgery on eyes with pediatric uveitis with IOL implantation leads to satisfactory and superior visual outcomes and no differences in complication rates apart from an increased prevalence of visual axis opacification and a decreased prevalence of hypotony when compared to aphakia. However, limitations of the retrospective design and the presence of selection bias necessitate a careful interpretation.

Update on noninfectious uveitis in children and its treatment

PURPOSE OF REVIEW

To give an overview of recently published articles covering risk factors, novel biomarkers and treatment for noninfectious uveitis in children.

RECENT FINDINGS

In the last few years, several genetic markers, serum biomarkers, aqueous humor markers, tear biomarkers and clinical factors have been identified, which are associated with childhood noninfectious uveitis. We describe the most important reports in this field that may help to tailor the screening and monitoring of this population in the future and might become the target of novel therapies. The advances in the biologic therapy of paediatric uveitis, thanks to evidence provided by the SYCAMORE, ADJUVITE and APTITUDE trials, offer new possibilities for the treatment of patients who fail methotrexate with adalimumab and tocilizumab. We discuss the importance of comprehensive outcome measures as proposed by the Multinational Interdisciplinary Working Group for Uveitis in Childhood (MIWGUC).

SUMMARY

Paediatric noninfectious uveitis is a sight-threatening condition and the identification of risk factors and novel biomarkers is critical for tailored management. Biologic therapies are revolutionizing the outcomes of patients resistant to conventional therapy. Increasing our knowledge of disease pathogenesis is crucial to improve targeting of screening to those at highest risk and stratification of treatments.

Prevalence, incidence and epidemiology of childhood uveitis

PURPOSE

To analyse the prevalence, incidence and aetiology of paediatric uveitis.

METHODS

A retrospective, population-based cohort study of Finnish children with uveitis in Northern Ostrobothnia Hospital District in 2008-2017. The data included parameters for age, gender, age at diagnosis, laterality, chronicity, anatomical distribution of the disease, aetiology and systemic association.

RESULTS

One hundred fifty patients aged <16 years (mean age 6.9 ± 3.9 years) with uveitis were included, out of whom 53% were girls. The first uveitis episode occurred at 1-6 years in 59%, and 62% of them were girls. In the age group of 7-15 years, boys were diagnosed with uveitis more frequently than girls (61% versus 39%, respectively). Seventy percent of the girls were diagnosed with their first uveitis episode at the age of 1-6 years, whereas only 48% of the boys were diagnosed at that age. The prevalence of uveitis increased from 64/100 000 children <16 years in 2008 (95% CI, 47.7-84.2) to 106/100 000 in 2017 (95% CI, 84.6-130.2). The incidence of childhood uveitis in 2008-2017 was 14/100 000 person-years in children <16 years (95% CI, 11.3-16.5). Eighty-seven percent of the cases were non-infectious, 9% were infectious, and 3% had masquerade syndromes. Sixty-one percent of patients had juvenile idiopathic arthritis (JIA).

CONCLUSION

The prevalence of paediatric uveitis has increased during the last decade in both genders. Uveitis is more frequent in girls, and they were diagnosed at a younger age than boys. Idiopathic cases and JIA accounted for a majority of aetiological features.

M, Dubey N. Pediatric uveitis: a retrospective analysis at a tertiary eye care hospital in South India

PURPOSE

To analyze the demographics, etiology, complications, treatment modalities, and visual outcomes in pediatric uveitis patients at a tertiary eye care hospital.

METHODS

A retrospective review of medical records of pediatric uveitis patients who presented with us from January 2014 to January 2020 was evaluated.

RESULTS

Out of the 178 pediatric uveitis patients, 65 children were included in the study. The most common age group was 6-10 years (46%). Of the included patients, 36 (55.4%) were male and 29 (44.6%) were female. Presentation was bilateral in 39 (60%) and unilateral in 26 (40%). Anterior uveitis was seen in 19 (29.23%), intermediate in 18 (27.69%), posterior in 16 (24.62%), and panuveitis in 12 (18.46%) patients. There were 2 cases of masquerades. Non-infectious uveitis was the most commonly seen, in 48 (73.84%) of total cases, among which 21 (43.75%) were idiopathic and 7 (14.58%) were associated with juvenile idiopathic (JIA) arthritis. Infectious uveitis was present in 17 (26.15%); the most common etiology was toxoplasmosis. Baseline visual acuity was low in 22 (33.84%) children. After initiating treatment, 37 (56.92%) showed improvement in vision and 10 (15.38%) had worsening of vision. Intraocular pressure (IOP) rise was seen in 5 (7.69%) children; 51 (78.46%) children required medical management and 16 (24.61%) children required surgical intervention; 46 (70.76%) children had uveitis related complications out of which most of them 30 (65.21%) were present at baseline.

CONCLUSIONS

Anterior and intermediate uveitis were the most common types observed in our study. Toxoplasmosis was the most common type of infectious uveitis and JIA the most common cause in non-infectious type apart from idiopathic uveitis. Posterior uveitis had low visual acuity at baseline and follow-up. Children presented to us with poor visual acuity and complications at baseline, hence an early referral to a tertiary eye hospital and management accordingly can improve the quality of vision and visual rehabilitation.

Childhood Uveitis

Childhood uveitis is an ophthalmological challenge, since on the one hand it often remains asymptomatic and difficult to detect, and on the other hand it often has a chronic course and is associated with a high risk of complications threatening the vision. The most important risk factors for childhood uveitis are underlying rheumatic diseases; recommendations for ophthalmological monitoring have been developed together with paediatric rheumatologists. Intermediate and posterior uveitis are rare in children. The therapy must effectively control inflammation and at the same time cause only minimal side effects. Since steroids in particular cause side effects frequently, an immunosuppressive therapy must be initiated early in an interdisciplinary cooperation with paediatric rheumatologists and parents with the goal of minimising steroids.
