RESUMEN
BACKGROUND: Macular holes cause severe impairment of sight. With the aim of improving the outcome of surgery for macular holes, particularly larger macular holes (those measuring over 400 µm), a variable period of face-down positioning may be advised. This review is an update of a Cochrane Review published in 2011. OBJECTIVES: To evaluate the effect of postoperative face-down positioning on the outcome of surgery for macular hole. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2022, Issue 5), which contains the Cochrane Eyes and Vision Trials Register, Ovid MEDLINE, Ovid Embase, the ISRCTN registry, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform. There were no date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 25 May 2022. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in which postoperative face-down positioning was compared to no face-down positioning following surgery for macular holes. The primary outcome of interest was closure of the macular hole. Other outcomes of interest included visual outcomes, quality of life outcomes, and the occurrence of adverse events. Pairs of review authors independently selected studies for inclusion, extracted data, assessed risk of bias, and evaluated the certainty of evidence using GRADE. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We analysed dichotomous data as risk ratios (RRs), and continuous data as mean differences (MDs), with 95% confidence intervals (CI). The unit of analysis was eyes. MAIN RESULTS: We included eight studies allocating a total of 709 eyes (699 participants). There was heterogeneity in study design, including the control group treatment (from no positioning to strict maintenance of other 'face-forward' postures) and surgical procedures (with or without inner limiting membrane peeling, with or without cataract surgery). There were also different durations of positioning, with two studies using 3 days, two studies using 5 days, and three studies using 10 days of face-down positioning. Whilst the overall risk of bias was low, all included studies were judged to be at high or unclear risk of bias due to absence of assessment of adherence to the 'prescribed' intervention of face-down positioning or posturing. The primary outcome of successful anatomical hole closure at one to six months following surgery was reported in 95 of every 100 eyes of participants advised to position face-down for at least three days after surgery, and in 85 of every 100 eyes of participants not advised to position face-down (RR 1.05, 95% CI 0.99 to 1.12, 709 eyes, 8 studies, I² = 44%). Amongst the 327 eyes of participants with macular holes of at least 400 µm, hole closure was noted in 94 of every 100 eyes of participants advised to position face-down, and in 84 of every 100 eyes of participants not advised to position face-down (RR 1.08, 95% CI 0.93 to 1.26, 5 studies, I² = 62%). Amongst the 129 eyes of participants with macular holes of less than 400 µm, hole closure was noted in 100 of every 100 eyes of participants advised to position face-down, and in 96 of every 100 eyes of participants not advised to position face-down (RR 1.03, CI 0.97 to 1.11, 4 studies, I² = 0%). The certainty of the evidence was low, downgraded for imprecision (CIs including no effect) and study design limitations (with different durations of face-down posturing used in the absence of a dose-response gradient, and limitations in measuring the exposure). Meta-analysis of visual acuity data was challenging given the use of different definitions of postoperative visual outcome across studies. Three studies reported findings by gain in Early Treatment Diabetic Retinopathy Study (ETDRS) letters (MD 2.04, 95% CI -0.01 to 4.09, very low-certainty evidence). Meta-analyses of quality of life data were not possible because of inconsistency in outcome metrics across studies. One study reported no difference between groups in quality of life, as reported on a validated quality of life metric scale (the National Eye Institute Visual Function Questionnaire - 25 (NEI VFQ-25), between face-down positioning for five days and non-face-down positioning (median NEI VFQ-25 score was 89 (interquartile range (IQR) 76 to 94) in the face-down group versus 87 (IQR 73 to 93) in the non-face-down group (adjusted mean difference on a logistic scale 0.02, 95% CI -0.03 to 0.07, P = 0.41)). Two studies reported increased ease of positioning and less pain in non-face-down positioning groups on non-validated 0-to-10-point visual analogue scores. On an ease-of-positioning score running from 0 (very difficult) to 10 (very easy), there were consistent reports of the discomfort associated with face-down positioning: the median participant-reported ease-of-positioning score was 6 (IQR 4 to 8) in those undergoing 5 days of face-down positioning versus 9 (IQR 7 to 10) in the comparator group (P = 0.01). On a pain score with 0 being pain-free and 10 being in severe pain, mean pain score was 6.52 ± 2.48 in the face-down positioning group versus 2.53 ± 2.6 in the non-face-down positioning group. The adverse event of postoperative nerve compression occurred in less than 1 in every 100 (3 per 1000) participants advised to position face-down, and 0 in every 100 participants not advised to position face-down (699 participants, 8 studies, moderate-certainty evidence). AUTHORS' CONCLUSIONS: We identified eight RCTs evaluating face-down positioning following surgery for macular hole. The included studies were not all directly comparable due to differences in the surgical techniques used and the durations of postoperative positioning advised. Low-certainty evidence suggests that face-down positioning may have little or no effect on macular hole closure after surgery. Face-down positioning is a low-risk intervention, with serious adverse events affecting fewer than 1 in 300 people. We suggest that any future trials focus on patients with larger macular holes, with interventions and outcome measures used in previous trials (i.e. with inner limiting membrane peeling, positioning durations of three to five days, and validated quality of life metrics) to allow future meta-analyses to determine any effect with greater precision and confidence.

PURPOSE: Appropriate correction of aphakia is key to good outcomes. There may be clinical settings where and populations in whom accessing or managing aphakic contact lenses is challenging. Strategies to target the increased risk of visual axis opacity (VAO) after primary intraocular lens (IOL) implantation in infancy are necessary. We describe the predictors of VAO after primary IOL implantation for unilateral or bilateral congenital or infantile cataract in children younger than 2 years of age. DESIGN: Population-based (United Kingdom and Ireland), prospective, inception cohort study undertaken through a national clinical network. PARTICIPANTS: A total of 105 children (57 with bilateral cataract, 48 with unilateral cataract, total 162 eyes) undergoing primary IOL implantation in the first 2 years of life between January 2009 and December 2010. METHODS: Observational longitudinal study with multilevel, multivariable modeling to investigate associations between outcome of interest and child- and treatment-specific factors, including age, axial length, socioeconomic status, IOL model, and postoperative steroid use. MAIN OUTCOME MEASURES: Postoperative proliferative or inflammatory visual axis opacity (VAO) requiring surgical correction. RESULTS: Visual axis opacity occurred in 67 eyes (45%), typically within the first postoperative year. Use of a 3-piece IOL model (odds ratio [OR], 0.3; 95% confidence interval [CI], 0.09-0.99, P = 0.03) and increasing age at surgery (OR, 0.97, 95% CI, 0.95-0.99, P = 0.02) were each independently protective against the development of proliferative VAO. Inflammatory VAO was independently associated with socioeconomic deprivation (OR, 5.39; 95% CI, 1.46-19.89; P = 0.01). CONCLUSIONS: Visual axis opacification is common after IOL implantation in early childhood. The findings of this prospective cohort study suggest that the use of 3-piece IOL models may reduce the risk of pseudophakic VAO in children younger than 2 years of age.

Amblyopia is a neurodevelopmental disorder that affects at least 2% of most populations and can lead to permanently reduced vision if not detected and treated within a specific period in childhood. Whole-population screening of children younger than 5 years is applied in many countries. The substantial diversity in existing programmes reflects their heterogeneous implementation in the absence of the complete evidence base that is now a pre-requisite for instituting screening. The functional importance of amblyopia at an individual level is unclear as data are scarce, but in view of the high prevalence the population-level effect might be notable. Screening of all children aged 4-5 years (eg, at school entry) confers most benefit and addresses inequity in access to timely treatment. Screening at younger ages is associated with increased risk of false-positive results, and at older ages with poor outcomes for children with moderate to severe amblyopia. We suggest that the real-life adverse effects of amblyopia should be characterised and screening and diagnosis should be standardised.

Young people with disabilities may face barriers to optimal management of menstrual health, including the management of menarche, a unique stage of development. This systematic review examined the barriers to and facilitators of a positive experience of menarche for young people with visual, hearing, or mobility impairments. The MEDLINE, Embase, PsychINFO bibliographic databases, and grey literature were systematically searched in February 2022 to identify relevant research. Thematic synthesis of the extracted study findings was undertaken, using a team-based approach. A total of seven primary qualitative, and 1 mixed method studies were eligible for inclusion. The themes identified through metasynthesis were: timeliness of pre-menarcheal access, with many being unaware of menarche before it occurred, leading to fear and shock at their first period; resonance, with individuals reporting positive impacts of guidance from those with similar disabilities; and frame, the impact of surrounding societal narratives on the experience of menarche. Families, and those involved in the care of children with visual, hearing, and mobility impairments should be made aware of the importance of timely and resonant menarcheal support and guidance for these individuals and of broadcasting positive surrounding narratives of menarche. This should enable a positive experience of menarche for these vulnerable young people, supporting a good trajectory for later-life menstrual health.

BACKGROUND/AIMS: The UK Medicines and Healthcare products Regulatory Agency (MHRA) has published suspected adverse drug reactions to vaccines against COVID-19. Ocular inflammatory events following COVID-19 vaccination have been reported worldwide. METHODS: We analysed MHRA data on spontaneous reports of suspected ocular inflammatory events following COVID-19 vaccination between January 2021 and September 2022. RESULTS: The MHRA received 300 UK spontaneous suspected reports of ocular inflammatory events following COVID-19 vaccination, with a calculated prevalence of 6.6 events per 1 000 000 vaccinated individuals. Anterior uveitis was the most common phenotype (58.3%), followed by optic neuritis in 39.3%. Median number of days between vaccination and onset was 8 days. Resolution of the event was seen in 52.3%. CONCLUSION: Ocular inflammatory events following COVID-19 vaccination have a very rare prevalence in the UK. There is no increase in the reporting rate of uveitis, optic neuritis and scleritis following COVID-19 vaccination when compared with the range of incidence in the UK population. The Yellow Card System represents a vital instrument within the domain of pharmacovigilance, empowering patients and healthcare professionals to contribute to the ongoing monitoring of medication safety.
RESUMEN
BACKGROUND/OBJECTIVES: There is a paucity of online educational content targeting children and young people with uveitis. We evaluated the impact of a co-designed patient education video on subjective and objective understanding of childhood uveitis. SUBJECTS/METHODS: Co-designed patient education media were produced in collaboration with the Childhood Uveitis Studies steering group and the Great Ormond Street Hospital Generation R Young People's Advisory Group and narrated by children. Patients managed within the Uveitis service at GOSH were invited to take part in a pre-post survey, undertaken immediately prior to and following viewing of a patient education video. RESULTS: Forty-three patients participated. These were stratified according to age, duration of disease, and treatment type for analysis. Self-rated knowledge improved across all groups (p = 0.001), particularly in those with a new diagnosis of uveitis (Z = -8.124, p < 0.001). Objective knowledge scores improved across all questions, especially in younger children, those with new disease, and those on steroid only treatment (Z = -3.847, p < 0.001, Z = -3.975, p < 0.001, Z = -3.448, p < 0.001; respectively). Most participants reported the videos to be easy to understand and with the right amount of information. All stated that they learned something new. CONCLUSIONS: Patient understanding of disease and treatment is crucial to achieving the best possible outcomes for this chronic, relapsing remitting and potentially blinding disorder. Our findings data shows the potential value of co-designed patient information videos, specifically in our study benefitting younger patients and those recently diagnosed. We suggest that other clinical teams could collaborate fruitfully with patient groups to develop similar videos to target possible misinformation and potentially improve patient outcomes.

BACKGROUND: Evidence on the socioeconomic burden associated with childhood visual impairment, severe visual impairment and blindness (VI/SVI/BL) is needed to inform economic evaluations of existing and emerging interventions aimed at protecting or improving vision. This study aimed to evaluate the quantity and quality of literature on resource use and/or costs associated with childhood VI/SVI/BL disorders. METHODS: PubMed, Web of Science (Ovid), the National Health Service (NHS) Economic Evaluation Database and grey literature were searched in November 2020. The PubMed search was rerun in February 2022. Original articles reporting unique estimates of resource use or cost data on conditions resulting in bilateral VI/SVI/BL were eligible for data extraction. Quality assessment (QA) was undertaken using the Drummond checklist adapted for cost-of-illness (COI) studies. RESULTS: We identified 31 eligible articles, 27 from the peer-reviewed literature and four from the grey literature. Two reported on resource use, and 29 reported on costs. Cerebral visual impairment and optic nerve disorders were not examined in any included studies, whereas retinopathy of prematurity was the most frequently examined condition. The quality of studies varied, with economic evaluations having higher mean QA scores (82%) compared to COI studies (77%). Deficiencies in reporting were seen, particularly in the clinical definitions of conditions in economic evaluations and a lack of discounting and sensitivity analyses in COI studies. CONCLUSIONS: There is sparse literature on resource use or costs associated with childhood visual impairment disorders. The first step in addressing this important evidence gap is to ensure core visual impairment outcomes are measured in future randomised control trials of interventions as well as cohort studies and are reported as a discrete health outcome.

PURPOSE: We investigated the impact of operator parameters on the diagnostic performance of danterior segment optical coherence tomography (AS-OCT) in anterior uveitis. DESIGN: Prospective comparative diagnostic analysis. METHODS: Setting: Single site. STUDY POPULATION: Children aged under 18 years with anterior uveitis, recruited consecutively. OBSERVATION PROCEDURES: Index testing: Optovue RTVue80 AS-OCT using 'low-volume' (LV, horizontal and vertical cross-sections) and 'high-volume' (HV, 68 horizontal cross-sections) protocols. Reference testing: slit lamp examination with anterior chamber inflammation graded using standardisation of uveitis nomenclature (SUN). MAIN OUTCOME MEASURE: Index test performance metrics (sensitivity, specificity, likelihood ratios), utility for 'ruling-in' and 'ruling-out' disease (positive / negative predictive values, PPV/NPV), receiver operating characteristic (ROC) curves to explore the impact of different imaging derived metrics, multivariable multilevel regression analyses to quantify correlation of index to reference testing, and repeatability indices across protocols. RESULTS: 40 children (77 eyes: 51 eyes at SUN grade 0, 10 at SUN0.5+, 8 at SUN1+, 8 SUN≥2+ or higher) were included. There was high repeatability across protocols (0.98, p<0.001, 95% CI 0.75-1.0). OCT resulted in strong predictive values for 'ruling-out' (LV-scan NPV 82.9%, 95% CI 71.5 - 90.4%; HV-scan NPV 100%, 95% CI 3% to 100%), and but less predictive value for 'ruling-in' SUN≥0.5+ (LV-scan PPV 52.8% 95% CI 41.5 - 63.7%; HV-scan PPV 34.2%, 95% CI 33.3 to 35.1%). Detection of more than 1 cell within a cross sectional scan was strongly suggestive of clinical activity, with area under the curve of 0.76 (95% CI 0.62 - 0.89) for SUN≥0.5+, and 0.85 (95% CI 0.73- 0.98), for the detection of SUN≥1+. Cell count correlated with SUN grades at higher levels of inflammation (SUN≥2+ both protocols, SUN≥1+ HV-scans). There was an independent positive association between age and AS-OCT cell (adjusted correlation coefficient 0.2 cells for each additional year of age). CONCLUSIONS: Operator dependent factors impact the diagnostic and quantification performance of AS-OCT for anterior chamber inflammation. However, the strong, 'dose-respondent' correlation of low-volume protocols with SUN grading promises clinical utility without the storage and analysis burden of high-volume approaches. Further work will involve exploration of the need for age-specific image metric interpretation.
RESUMEN
Purpose: Anterior segment optical coherence tomography (AS-OCT) is an emerging diagnostic and monitoring tool for anterior uveitis. We investigated AS-OCT findings in the eyes of a large, diverse population of children free of uveitis to establish its potential to "rule out" accurately those without disease. Methods: In this cross-sectional observational study, image acquisition was performed with swept source AS-OCT (Heidelberg Anterion), using a protocol of 13 B-scans per volume, from 217 children (434 eyes) aged 5 to 15 years, with analysis of acquired images (identification of apparent inflammatory cells, or "cell events") by multiple graders. Outcomes of interest were median and maximum cell event count (MEDCC, MAXCC) per B-scan from each eye and the total cell event count (TCC) per volume scan. Results: At least one cell event was detected in volume scans of 76% of eyes (329/434) and 87% of children (189/217). The maximum number (MAXCC) per scan ranged from 0 to 6 (median, 2). There was a strong positive association between increasing age (years) and the number of cell events detected within a volume scan following adjustment for gender and iris color (adjusted regression coefficient for TCC 0.5; P < 0.0001; 95% confidence interval, 0.4-0.7). Conclusions: Our findings demonstrate that apparent inflammatory cells are detectable on AS-OCT in the apparently healthy eyes of children and furthermore suggest early life developmental changes in blood-iris barrier stability that merit further exploration. We provide the foundation for the normative data set necessary for establishing the clinical utility of AS-OCT for surveillance of children with inflammatory eye diseases.

PURPOSE: Treatment with glucocorticoids following paediatric cataract surgery is crucial to prevent inflammation, but may lead to secondary glaucoma, and hypothalamic-pituitary-adrenal axis suppression. We wish to compare glaucoma outcomes following high-dose and low-dose glucocorticoid treatment after paediatric cataract surgery. METHODS: This cohort study included Danish children undergoing cataract surgery before 10 years of age, receiving either a low-dose or high-dose postoperative glucocorticoid treatment. Case identification and collection of a standardized dataset were retrospective, from 1 January 2010 to 31 December 2016, and prospective thereafter, until 31 December 2021. High-dose treatment included 0.5-1.0 mg subconjunctival depot dexamethasone or methylprednisolone, followed by 6-8 drops of dexamethasone for 1 week, tapered by one drop weekly. Low-dose treatment included 6 drops for 3 days, followed by 3 drops for 18 days. Sustained (>3 months) ocular hypertension or glaucoma was compared between the two groups. RESULTS: Overall, 267 children (388 eyes) were included in the study. Ninety-five children (133 eyes) had received high-dose treatment and had a median follow-up time of 89 months (IQR: 57.2-107.4), while 173 children (255 eyes) had received the low-dose treatment and had a median follow-up time of 40.5 months (IQR: 22.9-60.4). Survival curves showed a lower risk of glaucoma in the low-dose group for children with axial lengths ≥18 mm. CONCLUSION: Low-dose glucocorticoid treatment was associated with a lower risk of glaucoma in children with axial lengths ≥18 mm. The same effect was not observed in children with shorter eyes. High-dose glucocorticoid should be limited in children undergoing cataract surgery.
RESUMEN
BACKGROUND: The utility of medical imaging is dependant on image quality. We aimed to develop and validate quality criteria for ocular anterior segment optical coherence tomography (AS-OCT) images. METHODS: We undertook a cross-sectional study using AS-OCT images from patients aged 6-16. A novel three-level grading system (good, limited or poor) was developed based on the presence of image artefact (categorised as lid, eyelash, cropping, glare, or movement artefact). Three independent experts graded 2825 images, with agreement assessed using confusion matrices and intraclass correlation coefficients (ICC) for each parameter. RESULTS: There was very good inter-grader IQA agreement assessing image quality with ICC 0.85 (95 %CI: 0.84-0.87). The most commonly occurring artefact was eyelash artefact (1008/2825 images, 36 %). Graders labelled 621/2825 (22 %) images as good and 384 (14 %) as poor. There was complete agreement at either end of the confusion matrix with no 'good' images labelled as 'poor' by other graders, and vice versa. Similarly, there was very good agreement when assessing presence of lash (0.96,0.94-0.98), movement (0.97,0.96-0.99), glare (0.82,0.80-0.84) and cropping (0.90,0.88-0.92). CONCLUSIONS: The novel image quality assessment criteria (IQAC) described here have good interobserver agreement overall, and excellent agreement on the differentiation between 'good' and 'poor' quality images. The large proportion of images graded as 'limited' suggests the need for refine this classification, using the specific IQAC features, for which we also report high interobserver agreement. These findings support the future potential for wider clinical and community care implementation of AS-OCT for the diagnosis and monitoring of ocular disease.

BACKGROUND/AIMS: Evaluation of telemedicine care models has highlighted its potential for exacerbating healthcare inequalities. This study seeks to identify and characterise factors associated with non-attendance across face-to-face and telemedicine outpatient appointments. METHODS: A retrospective cohort study at a tertiary-level ophthalmic institution in the UK, between 1 January 2019 and 31 October 2021. Logistic regression modelled non-attendance against sociodemographic, clinical and operational exposure variables for all new patient registrations across five delivery modes: asynchronous, synchronous telephone, synchronous audiovisual and face to face prior to the pandemic and face to face during the pandemic. RESULTS: A total of 85 924 patients (median age 55 years, 54.4% female) were newly registered. Non-attendance differed significantly by delivery mode: (9.0% face to face prepandemic, 10.5% face to face during the pandemic, 11.7% asynchronous and 7.8%, synchronous during pandemic). Male sex, greater levels of deprivation, a previously cancelled appointment and not self-reporting ethnicity were strongly associated with non-attendance across all delivery modes. Individuals identifying as black ethnicity had worse attendance in synchronous audiovisual clinics (adjusted OR 4.24, 95% CI 1.59 to 11.28) but not asynchronous. Those not self-reporting their ethnicity were from more deprived backgrounds, had worse broadband access and had significantly higher non-attendance across all modes (all p<0.001). CONCLUSION: Persistent non-attendance among underserved populations attending telemedicine appointments highlights the challenge digital transformation faces for reducing healthcare inequalities. Implementation of new programmes should be accompanied by investigation into the differential health outcomes of vulnerable populations.

BACKGROUND: Diabetic eye screening (DES) represents a significant opportunity for the application of machine learning (ML) technologies, which may improve clinical and service outcomes. However, successful integration of ML into DES requires careful product development, evaluation, and implementation. Target product profiles (TPPs) summarize the requirements necessary for successful implementation so these can guide product development and evaluation. OBJECTIVE: This study aims to produce a TPP for an ML-automated retinal imaging analysis software (ML-ARIAS) system for use in DES in England. METHODS: This work will consist of 3 phases. Phase 1 will establish the characteristics to be addressed in the TPP. A list of candidate characteristics will be generated from the following sources: an overview of systematic reviews of diagnostic test TPPs; a systematic review of digital health TPPs; and the National Institute for Health and Care Excellence's Evidence Standards Framework for Digital Health Technologies. The list of characteristics will be refined and validated by a study advisory group (SAG) made up of representatives from key stakeholders in DES. This includes people with diabetes; health care professionals; health care managers and leaders; and regulators and policy makers. In phase 2, specifications for these characteristics will be drafted following a series of semistructured interviews with participants from these stakeholder groups. Data collected from these interviews will be analyzed using the shortlist of characteristics as a framework, after which specifications will be drafted to create a draft TPP. Following approval by the SAG, in phase 3, the draft will enter an internet-based Delphi consensus study with participants sought from the groups previously identified, as well as ML-ARIAS developers, to ensure feasibility. Participants will be invited to score characteristic and specification pairs on a scale from "definitely exclude" to "definitely include," and suggest edits. The document will be iterated between rounds based on participants' feedback. Feedback on the draft document will be sought from a group of ML-ARIAS developers before its final contents are agreed upon in an in-person consensus meeting. At this meeting, representatives from the stakeholder groups previously identified (minus ML-ARIAS developers, to avoid bias) will be presented with the Delphi results and feedback of the user group and asked to agree on the final contents by vote. RESULTS: Phase 1 was completed in November 2023. Phase 2 is underway and expected to finish in March 2024. Phase 3 is expected to be complete in July 2024. CONCLUSIONS: The multistakeholder development of a TPP for an ML-ARIAS for use in DES in England will help developers produce tools that serve the needs of patients, health care providers, and their staff. The TPP development process will also provide methods and a template to produce similar documents in other disease areas. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/50568.
RESUMEN
BACKGROUND: Juvenile idiopathic arthritis (JIA)-associated uveitis typically presents as a silent chronic anterior uveitis and can lead to blindness. Adherence to current screening guidelines is hampered by complex protocols which rely on the knowledge of specific JIA characteristics. The Multinational Interdisciplinary Working Group for Uveitis in Childhood identified the need to simplify screening to enable local eye care professionals (ECPs), who carry the main burden, to screen children with JIA appropriately and with confidence. METHODS: A consensus meeting took place in January 2023 in Barcelona, Spain, with an expert panel of 10 paediatric rheumatologists and 5 ophthalmologists with expertise in paediatric uveitis. A summary of the current evidence for JIA screening was presented. A nominal group technique was used to reach consensus. RESULTS: The need for a practical but safe approach that allows early uveitis detection was identified by the panel. Three screening recommendations were proposed and approved by the voting members. They represent a standardised approach to JIA screening taking into account the patient's age at the onset of JIA to determine the screening interval until adulthood. CONCLUSION: By removing the need for the knowledge of JIA categories, antinuclear antibody positivity or treatment status, the recommendations can be more easily implemented by local ECP, where limited information is available. It would improve the standard of care on the local level significantly. The proposed protocol is less tailored to the individual than the 'gold standard' ones it references and does not aim to substitute those where they are being used with confidence.
RESUMEN
In a recent issue of The Journal of Rheumatology, Berard et al1 reported on the development of the Canadian recommendations for the screening, monitoring, and treatment of uveitis associated with juvenile idiopathic arthritis ( JIA).1 The guidance from this national multidisciplinary JIA-associated uveitis working group had a welcome and necessary focus on the importance of disease control but omitted a definition of controlled disease.
RESUMEN
BACKGROUND AND OBJECTIVES: Early detection is critical to achieving optimal outcomes in children with congenital cataract. We hypothesized that detection of congenital cataract in preterm infants would be delayed compared with term/post-term peers due to delayed delivery of whole population child health interventions. METHODS: Secondary analysis of data using a nested case-control study approach in a prospective population-based cohort study. Inclusion criteria comprised children diagnosed with congenital cataract requiring surgical intervention during the first two years of life in UK and Ireland in 2009 and 2010. Association between late detection (after eight weeks post-natal age, ie outside the neonatal and infant eye national screening programme) of cataract and preterm birth (gestational age less than 37 weeks) was assessed using multivariable logistic regression. RESULTS: Of 186 children with congenital cataract, 17 children were born preterm (9%, gestational age range 24-37weeks). Neonatal detection occurred in 64/186 (34%), and late detection in 64 children (34%). Late detection was independently associated with premature birth, specifically moderate/late preterm birth (adjusted odds ratio 3.0, 95%CI 1.1 to 8.5). CONCLUSIONS: Our findings suggest that, despite enhanced eye surveillance being recommended for those born moderate/late preterm (32+ weeks gestational age, ie not eligible for retinopathy of prematurity screening), congenital cataract is not being effectively detected through the routine screening programme for this vulnerable group. It is necessary to improve the effectiveness of the screening programme, and care must be taken to ensure that competing health care needs of preterm children do not prevent universal child health interventions.
