Neurovisual Manifestations in Children with Mild COVID-19: An Association to Remember.

Neurovisual involvement has been reported in a number of patients with severe SARS-CoV-2 disease (COVID-19), mainly among adult patients. In children, such involvement has been reported in rare cases, often in those presenting with severe forms of COVID-19. The aim of this work is to explore the association between mild COVID-19 and neurovisual manifestations. We report the cases of three previously healthy children who developed neurovisual manifestations following mild acute COVID-19, analysing the clinical phenotype, the latency between the onset of acute COVID-19 and neurovisual involvement, and the kinetic of resolution. Our patients developed different clinical patterns, including visual impairment and ophthalmoplegia. In two cases, these clinical features occurred during acute COVID-19, while in the third patient their development was delayed after 10 days from disease onset. Furthermore, the dynamics of resolution were different, with one patient showing remission after 24 hours, the second after 30 days, and the third showing persistence of the strabismus after 2 months of follow-up. The spreading of COVID-19 among the paediatric population will probably lead to an increase of atypical disease forms, including those presenting with neurovisual involvement. Therefore, a better knowledge of the pathogenic and clinical features of these manifestations is warranted.

Narrative medicine to investigate the quality of life and emotional impact of inherited retinal disorders through the perspectives of patients, caregivers and clinicians: an Italian multicentre project.

OBJECTIVES: Although inherited retinal disorders (IRDs) related to the gene encoding the retinal pigment epithelium 65kD protein (RPE65) significantly impact the vision-related quality of life (VRQoL), their emotional and social aspects remain poorly investigated in Italy. Narrative Medicine (NM) reveals the more intimate aspects of the illness experience, providing insights into clinical practice. DESIGN AND SETTING: This NM project was conducted in Italy between July and December 2020 and involved five eye clinics specialised in IRDs. Illness plots and parallel charts, together with a sociodemographic survey, were collected through the project's website; remote in-depth interviews were also conducted. Narratives and interviews were analysed through NVivo software and interpretive coding. PARTICIPANTS: 3 paediatric and 5 adult patients and eight caregivers participated in the project; 11 retinologists globally wrote 27 parallel charts; 5 professionals from hospital-based multidisciplinary teams and one patient association member were interviewed. RESULTS: Findings confirmed that RPE65-related IRDs impact VRQoL in terms of activities and mobility limitations. The emotional aspects emerged as crucial in the clinical encounter and as informative on IRD management challenges and real-life experiences, while psychological support was addressed as critical from clinical diagnosis throughout the care pathway for both patients and caregivers; the need for an IRDs 'culture' emerged to acknowledge these conditions, and therefore, promoting diversity within society. CONCLUSIONS: The project was the first effort to investigate the impact of RPE65-related IRDs on the illness experience through NM, concomitantly addressing the perspectives of paediatric and adult patients, caregivers and healthcare professionals and provided preliminary insights for the knowledge of RPE65-related IRDs and the clinical practice.

Effects of remote learning during the COVID-19 lockdown on children's visual health: a systematic review.

OBJECTIVES: Increased exposure to digital devices as part of online classes increases susceptibility to visual impairments, particularly among school students taught using e-learning strategies. This study aimed to identify the impact of remote learning during the COVID-19 lockdown on children's visual health. DESIGN: Systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SOURCES: Scopus, PubMed and ScienceDirect databases from the year 2020 onwards. ELIGIBILITY CRITERIA: We included cross-sectional, case-control, cohort studies, case series and case reports, published in English, Spanish or French, that approached the effects of remote learning during the COVID-19 lockdown on visual health in neurotypical children. DATA EXTRACTION AND SYNTHESIS: We included a total of 21 articles with previous quality assessments using the Joanna Briggs checklist. Risk of bias assessment was applied using the National Institutes of Health quality assessment tool for before-and-after studies with no control group; the tool developed by Hoy et al to assess cross-sectional studies; the Murad et al tool to evaluate the methodological quality of case reports and case series; and the Newcastle-Ottawa Scale for cohort studies. RESULTS: All but one study reported a deleterious impact of the COVID-19 lockdown on visual health in children. Overall, the most frequently identified ocular effects were refractive errors, accommodation disturbances and visual symptoms such as dry eye and asthenopia. CONCLUSIONS: Increased dependence on digital devices for online classes has either induced or exacerbated visual disturbances, such as rapid progression of myopia, dry eye and visual fatigue symptoms, and vergence and accommodation disturbances, in children who engaged in remote learning during the COVID-19 lockdown.

Electrophysiology-Guided Genetic Characterisation Maximises Molecular Diagnosis in an Irish Paediatric Inherited Retinal Degeneration Population.

Inherited retinal degenerations (IRDs) account for over one third of the underlying causes of blindness in the paediatric population. Patients with IRDs often experience long delays prior to reaching a definitive diagnosis. Children attending a tertiary care paediatric ophthalmology department with phenotypic (i.e., clinical and/or electrophysiologic) evidence suggestive of IRD were contacted for genetic testing during the SARS-CoV-2-19 pandemic using a "telegenetics" approach. Genetic testing approach was panel-based next generation sequencing (351 genes) via a commercial laboratory (Blueprint Genetics, Helsinki, Finland). Of 70 patient samples from 57 pedigrees undergoing genetic testing, a causative genetic variant(s) was detected for 60 patients (85.7%) from 47 (82.5%) pedigrees. Of the 60 genetically resolved IRD patients, 5% (n = 3) are eligible for approved therapies (RPE65) and 38.3% (n = 23) are eligible for clinical trial-based gene therapies including CEP290 (n = 2), CNGA3 (n = 3), CNGB3 (n = 6), RPGR (n = 5) and RS1 (n = 7). The early introduction of genetic testing in the diagnostic/care pathway for children with IRDs is critical for genetic counselling of these families prior to upcoming gene therapy trials. Herein, we describe the pathway used, the clinical and genetic findings, and the therapeutic implications of the first systematic coordinated round of genetic testing of a paediatric IRD cohort in Ireland.

Home-based screening tools for amblyopia: a systematic review protocol.

INTRODUCTION: Amblyopia is an important public health concern associated with functional vision loss and detrimental impact on the physical and mental well-being of children. The gold standard for diagnosis of amblyogenic conditions currently involves screening by orthoptists and/or ophthalmologists. The bloom of technology enables the use of home-based screening tools to detect these conditions at an early stage by the layperson in community, which could reduce the burden of screening in the community, especially during restrictions associated with the COVID-19 pandemic. Here, we propose a systematic review aiming to evaluate the accuracy and reliability of home-based screening tools compared with the existing gold standard. METHODS AND ANALYSIS: We aim to search for studies involving home-based screening tools for amblyopia among children aged under 18 years. Oxford Centre for Evidence-Based Medicine Level 4 evidence and above will be included, without language or time restrictions. The following platforms will be searched from inception to 31 August 2021: PubMed, Medline, The Cochrane Library, Embase, Web of Science Core Collection and Clinicaltrials.gov. Two independent reviewers will identify studies for inclusion based on a screening questionnaire. The search and screening will start on 14 August 2021 until 1 October 2021. We aim to complete our data analysis by 30 November 2021. Risk of bias will be assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool for diagnostic accuracy studies only. Our primary outcome measure is the diagnostic accuracy of home-based screening tools, while secondary outcome measures include validity, feasibility, reproducibility and cost-effectiveness, where available. ETHICS AND DISSEMINATION: Ethical approval is not necessary as no primary data will be collected. The findings will be disseminated through presentations at scientific meetings and peer-reviewed journal publication. PROSPERO REGISTRATION NUMBER: CRD42021233511.

The Impact of the First Peak of the COVID-19 Pandemic on a Paediatric Ophthalmology Service in the United Kingdom: Experience from Alder Hey Children's Hospital.

OBJECTIVE: The COVID-19 pandemic has led to significant service loss across the NHS, and ophthalmology is one of the greatest affected specialties. We attempt to quantify the impact of the first peak of the COVID-19 pandemic on a paediatric ophthalmology unit in a children's hospital in the United Kingdom (UK) and report lessons learnt to aid in the recovery of the service. METHODS AND ANALYSIS: Two eight-week periods of clinical activity were compared; one during the first UK peak of the COVID-19 pandemic and the other during a similar period the previous year. Four areas of clinical activity were included in the study: outpatient clinic appointments, theatre activity, outpatient referrals to ophthalmology and ward reviews. Appointment data was collected from departmental databases. RESULTS: During the first peak of the pandemic, outpatient clinic appointments were reduced by 87.2%, ophthalmic surgery by 90.9%, outpatient referrals to ophthalmology by 50.2% and ward reviews by 50%. The number of actual cancelled appointments was 1377, of which 6.8% were triaged as suitable for teleophthalmology. CONCLUSION: The COVID-19 pandemic has dramatically restricted clinical activity in the ophthalmology service. Paediatric ophthalmology is vulnerable to capacity issues and the consequences of delayed or cancelled appointments. Departments must adapt quickly and maximise capacity to help reduce the backlog and treat patients effectively and safely. Solutions such as teleophthalmology have potential although can be difficult in the paediatric population.

Pivoting to teleconsultation for paediatric ophthalmology and strabismus: Our experience during COVID-19 times.

PURPOSE: The objective is to analyse and report the data of teleconsultations provided to paediatric ophthalmology and strabismus patients during COVID-19 times and to elaborate our experience for guiding future teleconsultation practices to General, paediatric Ophthalmologists and Strabismologists. METHODS: Retrospective analysis of electronic medical record data of teleconsultations provided in the department of Strabismus, Paediatric and Neuro-ophthalmology was done. Patients with optic nerve related disorders were excluded. Study period was one month. Statistical analysis of collected data was done using Microsoft excel. RESULTS: A total of 198 patients were provided teleconsultations (an average of seven teleconsultations/day). The final analysis included 161 patients after excluding optic nerve related disorders. The median age was seven years. We had a near equal gender distribution (53% males and 47% females) of whom a third were new cases. Video calling was used in 14%, review of clinical photos shared was used in 53%. Rest of the 33% were given telephonic advice. Allergic conjunctivitis (14%), pseudophakia (9%), strabismus (12%), status post strabismus surgery (8%), cranial nerve palsies (11%) were common diagnoses. 19% (n = 30) were advised/needed visit in emergency services on same or next day. CONCLUSION: Our experience of teleconsultation during COVID-19 times for paediatric ophthalmology and strabismus patients was very encouraging. Pivoting teleconsultation platform can provide primary eye care to most of the patients and work as essential forward triage for rest. As we continue to further explore the currently available avenues in multimedia such as video conferencing and web/mobile based applications, we believe that tele-ophthalmology platform can provide a reliable service in patient care.
