'It would help people to help me': Acceptability of digital phenotyping among young people with visual impairment and their families.

Objectives: To explore the acceptability of an eHealth App for vision-related monitoring and symptom reporting among young people with a visual impairment and their parents. Methods: Qualitative investigation using virtual semi-structured focus groups (via Zoom software) of seven young participants with a genetic eye disorder including inherited retinal disease and structural eye abnormalities (e.g. microphthalmia), and 7 parents; all recruited from ocular genetic clinics at Moorfields Eye Hospital. Audio transcripts were analysed using thematic analysis. Results: Data were coded into six key themes: (1) increased involvement in care, (2) opportunity for less hospital-centric care, (3) better representation of visual impairment in a real-world setting, (4) trust in a reputable service provider, (5) harnessing data for health purposes and (6) intended purpose of the app. Both young people and their families were accepting of an eHealth app and felt they would be empowered by greater involvement in their care plan, if privacy of the data was retained, and information was managed correctly. While parents endorsed the opportunity for mental health tracking, young people were hesitant towards its inclusion. Conclusion: In summary, there was overall acceptability of an eHealth app among young people with a visual impairment and their parents. These findings will help to maximise the effective integration of digital phenotyping when monitoring and supporting young people experiencing sight loss.

Development and international validation of custom-engineered and code-free deep-learning models for detection of plus disease in retinopathy of prematurity: a retrospective study.

BACKGROUND: Retinopathy of prematurity (ROP), a leading cause of childhood blindness, is diagnosed through interval screening by paediatric ophthalmologists. However, improved survival of premature neonates coupled with a scarcity of available experts has raised concerns about the sustainability of this approach. We aimed to develop bespoke and code-free deep learning-based classifiers for plus disease, a hallmark of ROP, in an ethnically diverse population in London, UK, and externally validate them in ethnically, geographically, and socioeconomically diverse populations in four countries and three continents. Code-free deep learning is not reliant on the availability of expertly trained data scientists, thus being of particular potential benefit for low resource health-care settings. METHODS: This retrospective cohort study used retinal images from 1370 neonates admitted to a neonatal unit at Homerton University Hospital NHS Foundation Trust, London, UK, between 2008 and 2018. Images were acquired using a Retcam Version 2 device (Natus Medical, Pleasanton, CA, USA) on all babies who were either born at less than 32 weeks gestational age or had a birthweight of less than 1501 g. Each images was graded by two junior ophthalmologists with disagreements adjudicated by a senior paediatric ophthalmologist. Bespoke and code-free deep learning models (CFDL) were developed for the discrimination of healthy, pre-plus disease, and plus disease. Performance was assessed internally on 200 images with the majority vote of three senior paediatric ophthalmologists as the reference standard. External validation was on 338 retinal images from four separate datasets from the USA, Brazil, and Egypt with images derived from Retcam and the 3nethra neo device (Forus Health, Bengaluru, India). FINDINGS: Of the 7414 retinal images in the original dataset, 6141 images were used in the final development dataset. For the discrimination of healthy versus pre-plus or plus disease, the bespoke model had an area under the curve (AUC) of 0·986 (95% CI 0·973-0·996) and the CFDL model had an AUC of 0·989 (0·979-0·997) on the internal test set. Both models generalised well to external validation test sets acquired using the Retcam for discriminating healthy from pre-plus or plus disease (bespoke range was 0·975-1·000 and CFDL range was 0·969-0·995). The CFDL model was inferior to the bespoke model on discriminating pre-plus disease from healthy or plus disease in the USA dataset (CFDL 0·808 [95% CI 0·671-0·909, bespoke 0·942 [0·892-0·982]], p=0·0070). Performance also reduced when tested on the 3nethra neo imaging device (CFDL 0·865 [0·742-0·965] and bespoke 0·891 [0·783-0·977]). INTERPRETATION: Both bespoke and CFDL models conferred similar performance to senior paediatric ophthalmologists for discriminating healthy retinal images from ones with features of pre-plus or plus disease; however, CFDL models might generalise less well when considering minority classes. Care should be taken when testing on data acquired using alternative imaging devices from that used for the development dataset. Our study justifies further validation of plus disease classifiers in ROP screening and supports a potential role for code-free approaches to help prevent blindness in vulnerable neonates.

Creating a secure clinical 'Bring Your Own Device' BYOD photography service to document and monitor suspicious lesions in the lid oncology clinic.

BACKGROUND: Ophthalmic examinations are mostly documented using sketches and written descriptions. Improvements in app security and IT infrastructure mean that high-quality anterior segment photographs can be routinely collected with smartphones alone. The lid oncology team relied on pre-operative formal slit-lamp imaging in the one-stop biopsy clinic, a lengthy process with capacity limitations, that risked delays to care. METHODS: A Bring Your Own Device (BYOD) photography service was developed through a series of iterations and collaborations. Healthcare Assistants took photographs on iPhone SE with Quikvue lens attachments in Pando app. Lesions requiring a slit lamp were photographed by the doctor. Images were uploaded to the patient record twice weekly. The service was evaluated using time-motion studies, imaging quality and utility grading, and patient feedback. RESULTS: BYOD photography saved lid oncology patients 41 min (one-third of total appointment time) and reduced delays to treatment to zero. A patient survey reflected the acceptability of the service, with 100% feeling photography was important at every visit. In terms of utility, 97.5% of smartphone images were suitable for monitoring lesions and making management decisions. The management plan based on the smartphone photographs was consistent with the management plan formulated face-to-face in clinic in 92.5% images. CONCLUSION: BYOD photography has replaced formal slit-lamp imaging in the lid oncology service. This sustainable, cost-effective BYOD solution requires little training and can be adapted, reproduced, and scaled globally. BYOD photography can offer detailed records to monitor progress, contribute to remote care models, improve patient experience, and reducing medical error.

Enablers and Barriers to Deployment of Smartphone-Based Home Vision Monitoring in Clinical Practice Settings.

IMPORTANCE: Telemedicine is accelerating the remote detection and monitoring of medical conditions, such as vision-threatening diseases. Meaningful deployment of smartphone apps for home vision monitoring should consider the barriers to patient uptake and engagement and address issues around digital exclusion in vulnerable patient populations. OBJECTIVE: To quantify the associations between patient characteristics and clinical measures with vision monitoring app uptake and engagement. DESIGN, SETTING, AND PARTICIPANTS: In this cohort and survey study, consecutive adult patients attending Moorfields Eye Hospital receiving intravitreal injections for retinal disease between May 2020 and February 2021 were included. EXPOSURES: Patients were offered the Home Vision Monitor (HVM) smartphone app to self-test their vision. A patient survey was conducted to capture their experience. App data, demographic characteristics, survey results, and clinical data from the electronic health record were analyzed via regression and machine learning. MAIN OUTCOMES AND MEASURES: Associations of patient uptake, compliance, and use rate measured in odds ratios (ORs). RESULTS: Of 417 included patients, 236 (56.6%) were female, and the mean (SD) age was 72.8 (12.8) years. A total of 258 patients (61.9%) were active users. Uptake was negatively associated with age (OR, 0.98; 95% CI, 0.97-0.998; P = .02) and positively associated with both visual acuity in the better-seeing eye (OR, 1.02; 95% CI, 1.00-1.03; P = .01) and baseline number of intravitreal injections (OR, 1.01; 95% CI, 1.00-1.02; P = .02). Of 258 active patients, 166 (64.3%) fulfilled the definition of compliance. Compliance was associated with patients diagnosed with neovascular age-related macular degeneration (OR, 1.94; 95% CI, 1.07-3.53; P = .002), White British ethnicity (OR, 1.69; 95% CI, 0.96-3.01; P = .02), and visual acuity in the better-seeing eye at baseline (OR, 1.02; 95% CI, 1.01-1.04; P = .04). Use rate was higher with increasing levels of comfort with use of modern technologies (ß = 0.031; 95% CI, 0.007-0.055; P = .02). A total of 119 patients (98.4%) found the app either easy or very easy to use, while 96 (82.1%) experienced increased reassurance from using the app. CONCLUSIONS AND RELEVANCE: This evaluation of home vision monitoring for patients with common vision-threatening disease within a clinical practice setting revealed demographic, clinical, and patient-related factors associated with patient uptake and engagement. These insights inform targeted interventions to address risks of digital exclusion with smartphone-based medical devices.

Impact and Challenges of Integrating Artificial Intelligence and Telemedicine into Clinical Ophthalmology.

ABSTRACT: Aging populations and worsening burden of chronic, treatable disease is increasingly creating a global shortfall in ophthalmic care provision. Remote and automated systems carry the promise to expand the scale and potential of health care interventions, and reduce strain on health care services through safe, personalized, efficient, and cost-effective services. However, significant challenges remain. Forward planning in service design is paramount to safeguard patient safety, trust in digital services, data privacy, medico-legal implications, and digital exclusion. We explore the impact and challenges facing patients and clinicians in integrating AI and telemedicine into ophthalmic care-and how these may influence its direction.

Safety of video-based telemedicine compared to in-person triage in emergency ophthalmology during COVID-19.

BACKGROUND: the need for social distancing midst the COVID-19 pandemic has forced ophthalmologists to innovate with telemedicine. The novel process of triaging emergency ophthalmology patients via videoconsultations should reduce hospital attendances. However, the safety profile of such services were unknown. METHODS: in this retrospective cohort study, we reviewed case notes of 404 adults who used our videoconsultation service from 20/04/2020 to 03/05/2020. We compared these to 451 patient who attended eye casualty in person at the same time who were deemed not to require same day ophthalmic examination. FINDINGS: patients seen by videoconsultations tended to be younger (Median = 43 years, Inter-quartile range = 27 vs Median= 49 years, Inter-quartile range = 28)'. More males used the face-to-face triage (55%) while more females used videoconsultation (54%)%. Fewer patients seen by videoconsultations required specialist review compared to face-face triage [X 2 (1, N = 854) = 128.02, p<0.001)]. 35.5% of the patients initially seen by videoconsultation had unplanned reattendance within 1 month, compared to 15.7% in the group initially seen in person. X 2 (1, N = 234) = 7.31, p = 0.007). The rate of actual harm was no different (at 0% for each method), with perfect inter-grader correlation when graded independently by two senior ophthalmologists. 97% of patients seen on the video platform surveyed were satisfied with their care. INTERPRETATION: we demonstrate comparable patient safety of videoconsultations at one-month follow-up to in person review. The service is acceptable to patients and reduces the risk of COVID-19 transmission. We propose that videoconsultations are effective and desirable as a tool for triage in ophthalmology.

Creating the Moorfields' virtual eye casualty: video consultations to provide emergency teleophthalmology care during and beyond the COVID-19 pandemic.

BACKGROUND: The COVID-19 crisis forced hospitals in the UK dramatically to reduce outpatient activity. To provide continuity of care and to assist patients reluctant or unable to leave their homes, video consultations were rapidly implemented across routine and emergency ophthalmology services. OBJECTIVE: To describe the deployment and scaling to a large volume of teleophthalmology using a video consultation platform 'Attend Anywhere' in Moorfields Eye Hospital's accident and emergency (A&E) department (London, UK). METHOD: Patient satisfaction, waiting time, consultation duration, outcome and management were audited following the launch of the new virtual A&E service. RESULTS: In the 12 days following the service launch, 331 patients were seen by video consultation. 78.6% of patients (n=260) were determined not to need hospital A&E review and were managed with advice (n=126), remote prescription (n=57), general practitioner referral (n=27), direct referral to hospital subspecialty services (n=26) or diversion to a local eye unit (n=24). Mean patient satisfaction was 4.9 of 5.0 (n=62). The mean consultation duration was 12 min (range 5-31 min) and the wait time was 6 min (range 0-37 min). CONCLUSION: Video consultations showed greater than expected usefulness in the remote management of eye disease and supported a substantial reduction in the number of people visiting the hospital.

Type IV Hypersensitivity to Gold Weight Upper-Eyelid Implant: Case Report and Review of the Literature.

PURPOSE: Complications associated with gold-weight insertion for lagophthalmos are uncommon, recent reports have provided evidence to suggest that type IV hypersensitivity to gold can cause a persistent inflammatory reaction. METHODS: We present a case of a 46-year-old man who experienced persistent post-operative inflammation, and summarize previously documented cases. This patient underwent uncomplicated insertion of an upper eyelid gold weight for right-sided facial nerve palsy. He had no allergies or implanted metalwork. Post-operatively erythema was noted at seven-weeks and did not resolve. The weight was removed after six-months. RESULTS: The histopathological findings were in keeping with type IV hypersensitivity and similar to previous cases. CONCLUSIONS: Although infrequent, this complication has poor outcomes. The definitive management is removal of the weight. Information regarding implanted gold, and previous reactions should be elicited pre-operatively. Type IV hypersensitivity should be considered in patients with persistent inflammation that do not respond to antibiotic or steroid therapy.

Surgical safety checklist training: a national study of undergraduate medical and nursing student teaching, understanding and influencing factors.

INTRODUCTION: Use of the WHO surgical safety checklist is consistently recognised to reduce harm caused by human error during the perioperative period. Inconsistent engagement is considered to contribute to persistence of surgical Never Events in the National Health Service. Most medical and nursing graduates will join teams responsible for the perioperative care of patients, therefore appropriate undergraduate surgical safety training is needed. AIMS: To investigate UK medical and nursing undergraduate experience of the surgical safety checklist training. METHODS: An eight-item electronic questionnaire was distributed electronically to 32 medical schools and 72 nursing schools. Analysis was conducted for the two cohorts, and responses from final year students were included. RESULTS: 87/224 (38.8%) of medical students received teaching on the surgical safety checklist, compared with 380/711 (52.0%) of nursing students. 172/224 (76.8%) of medical students and 489/711 (66.9%) of nursing students understood its purpose and 8/224 (3.6%) medical students and 54/711 (7.4%) nursing students reported never being included in the Time Out. After adjusting for confounding factors, provision of formal teaching in checklist use increased understanding significantly (OR 50.39 (14.07 to 325.79, P<0.001)), as did routine student involvement in time outs (OR 5.72 (2.36 to 14.58, P<0.001)). DISCUSSION: Knowledge of perioperative patient safety systems and the ability to participate in safety protocols are important skills that should be formally taught at the undergraduate level. Results of this study show that UK undergraduate surgical safety checklist training does not meet the minimum standards set by the WHO.

Use of Alleviating Maneuvers for Periocular Facial Dystonias.

IMPORTANCE: Patients with benign essential blepharospasm or hemifacial spasm are known to use botulinum toxin injections and alleviating maneuvers to help control their symptoms. The clinical correlates between the use of botulinum toxin injections and the use of alleviating maneuvers are not well established. OBJECTIVE: To determine whether the use of alleviating maneuvers for benign essential blepharospasm or hemifacial spasm correlates with disease severity or botulinum toxin treatment. DESIGN, SETTING, AND PARTICIPANTS: A prospective cross-sectional observational study (designed in September 2013) of 74 patients with benign essential blepharospasm and 56 patients with hemifacial spasm who were consecutively recruited from adnexal clinics at Moorfields Eye Hospital (January-June 2014) to complete a questionnaire and undergo a clinical review. Data analysis was performed in December 2015. MAIN OUTCOMES AND MEASURES: Prevalence and type of alleviating maneuvers used for blepharospasm and hemifacial spasm, dystonia severity, and dose and frequency of botulinum toxin injections. RESULTS: Of the 74 patients with blepharospasm, 39 (52.7%) used alleviating maneuvers (mean [SD] age, 70.4 [9.1] years); of the 56 patients with hemifacial spasm, 25 (44.6%) used alleviating maneuvers (mean [SD] age, 66.5 [12.7] years). The most commonly used maneuver was the touching of facial areas (35 of 64 patients [54.7%]); other maneuvers included covering the eyes (6 of 64 patients [9.4%]), singing (5 of 64 patients [7.8%]), and yawning (5 of 64 patients [7.8%]). Patients with blepharospasm who used alleviating maneuvers scored higher on the Jankovic Rating Scale (median score, 5 vs 4; Hodges-Lehmann median difference, 1 [95% CI, 0-2]; P = .01) and the Blepharospasm Disability Index severity score (median score, 11 vs 4; Hodges-Lehmann median difference, 4 [95% CI, 1-7]; P = .01) than patients with blepharospasm who did not use alleviating maneuvers. Patients with hemifacial spasm who used alleviating maneuvers scored higher on the 7-item Hemifacial Spasm Quality of Life scale (median score, 7 vs 3; Hodges-Lehmann median difference, 4 [95% CI, 1-7]; P = .01) and the SMC Severity Grading Scale (median score, 2 vs 2; Hodges-Lehmann median difference, 0 [95% CI, 0-1]; P = .03) than patients with hemifacial spasm who did not use alleviating maneuver. The severity of dystonia correlated with botulinum toxin treatment for patients with blepharospasm (r = 0.23; P = .049) and patients with hemifacial spasm (r = 0.45; P = .001). There was no difference found in botulinum toxin treatment between patients who used alleviating maneuvers and those who did not, in either the blepharospasm group (150 vs 125 units; Hodges-Lehmann median difference, 20 units [95% CI, -10 to 70 units]; P = .15) or the hemifacial spasm group (58 vs 60 units; Hodges-Lehmann median difference, 0 units [95% CI, -15 to 20 units]; P = .83). CONCLUSIONS AND RELEVANCE: Half of the patients with periocular facial dystonias used alleviating maneuvers. Their use was associated with more severe disease but not with increased use of botulinum toxin. This may help to guide future therapies, such as advice on maneuver augmentation or tailored devices.

Red eyes and red-flags: improving ophthalmic assessment and referral in primary care.

Up to five percent of primary care consultations are eye-related, yet 96% of General Practitioners (GPs) do not undergo postgraduate ophthalmology training. Most do not feel assured performing eye assessments. Some red eye conditions can become sight threatening, and often exhibit red-flag features. These features include moderate pain, photophobia, reduced visual acuity (VA), eye-trauma, or unilateral marked redness. The aim of this project was to improve primary care assessment and referral of patients presenting with red-flag features based on the NICE 'Red Eye' Clinical Knowledge Summary recommendations. Data was collected retrospectively from 139 red eye consultations. A practice meeting highlighted poor awareness of red-flag features, low confidence levels in eye assessments, and time-constraints during appointments. Interventions were based on feedback from staff. These included a primary care teaching session on red-flag features, a VA measurement tutorial, and provision of a red eye toolkit, including VA equipment, to each consultation room. At baseline, each patient had on average 0.9 red-flag features assessed. Only 36.0% (9/25) of patients with red-flag features were appropriately referred to same-day ophthalmology services. Following two improvement cycles, a significant improvement was seen in almost every parameter. On average, each patient had 2.7 red-flag features assessed (vs 0.9, p<0.001). VA was assessed in 55.6% of consultations (vs 7.9%, p<0.001), pain was quantified in 81.5% (vs 20.9%, p=0.005), eye-trauma or foreign-body (51.8% vs 8.6%, p<0.001), extent of redness was documented in 66.7% (vs 14.4%, p<0.001). Only photophobia remained poorly assessed (18.5% vs 14.4%, p=0.75). Following this, 75.0% (6/8) of patients were appropriately referred. This project reflected the literature regarding low confidence and inexperience amongst GPs when faced with ophthalmic conditions. Improvements in education are required to ensure accurate assessments can be undertaken in a time-constrained environment.
