Determinants of non-attendance at face-to-face and telemedicine ophthalmic consultations.

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.

Tablet-based tests of everyday visual function in a diabetic macular oedema (DME) clinic waiting area: A feasibility study.

PURPOSE: (1) To assess the feasibility of conducting tablet-based vision tests in hospital clinic waiting areas; (2) To test the hypothesis that increasing severity of diabetic macular oedema (DME) is associated with the performance of tablet-based surrogates of everyday tasks and self-reported visual function. METHODS: Sixty-one people with mild (n = 28), moderate (n = 24) or severe (n = 9) DME performed two tablet-based tests of 'real-world' visual function (visual search and face recognition) while waiting for appointments in a hospital outpatient clinic. Participants also completed a tablet-based version of a seven-item, visual-functioning (VF-7) patient-reported outcome measure. Test performance was compared to previously published 99% normative limits for normally sighted individuals. RESULTS: Thirty-four participants (56%; 95% confidence interval [CI] 43%-68%) exceeded normative limits for visual search, while eight (13%; 95% CI 65%-24%) exceeded normative limits for face discrimination. Search duration was significantly longer for people with severe DME than those with mild and moderate DME (p = 0.01). Face discrimination performance was not significantly associated with DME severity. VF-7 scores were statistically similar across DME severity groups. Median time to complete all elements (eligibility screening, both tablet-based tasks and the VF-7) was 22 (quartiles 19, 25) min. Further, 98% and 87% of participants, respectively, reported the search task and face discrimination task to be enjoyable, while 25% and 97%, respectively, reported finding the two tasks to be difficult. CONCLUSIONS: Portable tablet-based tests are quick, acceptable to patients and feasible to be performed in a clinic waiting area with minimal supervision. They have the potential to be piloted in patients' homes for self-monitoring.

Expansion of patient eligibility for virtual glaucoma clinics: a long-term strategy to increase the capacity of high-quality glaucoma care.

AIMS: The virtual glaucoma clinic (VGC) is a well-established diagnostic pathway for delivery of glaucoma care. Current UK national guidance recommends VGCs for patients with ocular hypertension, glaucoma suspects or early glaucoma. This study evaluates whether expanded eligibility criteria, including other glaucoma phenotypes and disease stages, can deliver safe and effective care with a positive patient experience. METHODS: Records of over 8000 patients were reviewed in order to determine suitability for VGC attendance using expanded eligibility criteria. Patients with three prior consecutive visits within the glaucoma service were included. Follow-up interval, clinic type, visual acuity (VA), intraocular pressure (IOP) and visual field performance were recorded. Patient satisfaction was recorded for a sample of 118 patients. RESULTS: 2017 patients over 31 months were included. Two-thirds of eyes had ocular comorbidities, a fifth of eyes had undergone prior cataract surgery and 10% of eyes had undergone a prior laser treatment for glaucoma. After three visits, 32% of patients remained in the VGC, 42% were seen in face-to-face clinics and 25% were discharged. There were no clinically significant changes in VA, IOP and visual field performance during follow-up. 72% of patients expressed a preference to continue their care within VGCs. CONCLUSIONS: This study demonstrates that VGCs with expanded patient eligibility criteria can deliver high-quality glaucoma care that is safe, effective and with high levels of patient satisfaction. This approach provides a long-term solution to adapt delivery of glaucoma care to our expanding and ageing population.

System usability, user satisfaction and long-term adherence to mobile hyperacuity home monitoring-prospective follow-up study.

PURPOSE: To evaluate the usability and long-term adherence to the mobile hyperacuity app Alleye in patients with retinal pathology. METHODS: We enroled 72 patients (95 eyes) mainly treated for wet AMD (48/95; 50.5%). We calculated changes of clinical characteristics and the System Usability Score (SUS), and personal ratings of usefulness and number of tests performed per month at a follow-up visit of eighteen months. RESULTS: At baseline, mean best corrected visual acuity (BCVA) was 74.9 letters (SD 14.8), mean age was 69.9 (SD 11.4) and 39/72 (54.2%) were female. Of included patients, 47/72 (65.2%) reported to use mobile devices daily. The retention rate until last follow-up was 73.6 % (53/72). The median SUS score at baseline was 90 (interquartile range (IQR) 82.5-95) and 92.5 (IQR 82.5-95) in the follow-up. No association between changes of SUS and clinical characteristics was seen. At baseline, 76.4% (55/72) stated that they would recommend the app to a friend, 83.3% (60/72) were very satisfied with the app and 58/72 (80.6%) of respondents said they trusted the app. These assessments remained similar among patients remaining on the program until the follow-up. Patients who dropped out of the study (n = 19) did not differ in age, gender, BCVA, and SUS at baseline, but stated that they did not use the mobile device daily (Odds Ratio 7.40 (95%CI: 2.32-23.65); p = 0.001). CONCLUSIONS: The majority of users willing to perform home monitoring with the Alleye app are satisfied with the usability and have a positive attitude towards its trustworthiness and usefulness.

Introducing the 'Benign Eyelid Lesion Pathway': 1 year experience of synchronous tele-oculoplastics in a tertiary hospital.

BACKGROUND: Patients with benign eyelid lesions make up a large proportion of referrals to the oculoplastic service and lend themselves well to telemedicine with assessments heavily reliant on history, observation-based examination and photographs to enable management decision-making. Our tertiary unit set up tele-oculoplastics clinics for all new patients referred for benign eyelid lesions comprising tele-consultation with antecedent patient photograph: Benign Eyelid Lesion Pathway (BELP). One year on, we describe a retrospective analysis of 974 patients looking at distinct parameters of effectiveness. METHODS: We retrospectively collected data from electronic patient records (EPR) for BELP patients from July 2020 to August 2021 (n = 974). We analysed time efficiency (referral time to treatment plan, consultation duration in minutes, average waiting times, number of patients seen per clinician and DNA rate), accessibility, safety (via video surveillance clinic) and theatre utilisation. RESULTS: 57.3% (n = 558) were listed for a surgical procedure direct from tele-consultation with 94.9% (n = 513) of these proceeding to surgery; 22.8% (n = 222) were discharged, 10.7% (n = 104) had further video follow-up and 6.7% (n = 65) required face-to-face follow-up. Our results showed efficient referral-to-treatment times, waiting times, consultation times and non-attendance rate. There was only a 2.57% non-attendance rate. There was no missed diagnosis of a malignancy of a presumed benign lesion. CONCLUSION: Tele-oculoplastics provides a streamlined, safe, effective, and logistically convenient way to review benign eyelid lesions. With the increased waiting times for referral to biopsy of eyelid lesions, this clinic shows it is imperative to provide digital accessibility for patient assessment and booking to operating theatre.

Practical implementation of a q4-q16 aflibercept treat-and-extend pathway for the treatment of neovascular age-related macular degeneration: Updated guidance from a UK expert panel.

OBJECTIVES: This report, based on guidance from a panel of UK retina specialists, introduces a revised intravitreal aflibercept (IVT-AFL) treat-and-extend (T&E) pathway for the treatment of neovascular age-related macular degeneration (nAMD). The T&E pathway incorporates the updated IVT-AFL label (April 2021) allowing flexible treatment intervals of 4 weeks to 16 weeks, after three initiation doses and a further dose after 8 weeks. Practical guidance is provided on the clinical implementation of the revised pathway, with the aim of supporting clinical decision-making to benefit patients and addressing capacity issues in nAMD services. METHODS: Three structured round-table meetings of UK retina specialists were held online on 19 May, 16 June and 13 October 2021. These meetings were organised and funded by Bayer. RESULTS: The authors revised the previously published consensus pathway to reflect the changes to the IVT-AFL label and developed guidelines for the implementation of the pathway in UK clinical practice. The guidelines include topics such as recommendations for extending patients with 2- or 4-week adjustments, extending patients to 16-week treatment intervals, managing fellow eye involvement, and reducing treatment intervals for patients with particularly active disease. CONCLUSIONS: The revised IVT-AFL T&E nAMD pathway offers guidance to clinicians seeking to increase the dosing flexibility of IVT-AFL, with 4- to 16-week treatment intervals, in line with the updated IVT-AFL label, to meet the continually evolving demands of nAMD service provision.

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.

Transforming ophthalmology in the digital century-new care models with added value for patients.

Ophthalmology faces many challenges in providing effective and meaningful eye care to an ever-increasing group of people. Even health systems that have so far been able to cope with the quantitative patient increase, due to their funding and the availability of highly qualified professionals, and improvements in practice routine efficiency, will be pushed to their limits. Further pressure on care will also be caused by new active substances for the largest group of patients with AMD, the so-called dry form. Treatment availability for this so far untreated group will increase the volume of patients 2-3 times. Without the adaptation of the care structures, this quantitative and qualitative expansion in therapy will inevitably lead to an undersupply.There is increasing scientific evidence that significant efficiency gains in the care of chronic diseases can be achieved through better networking of stakeholders in the healthcare system and greater patient involvement. Digitalization can make an important contribution here. Many technological solutions have been developed in recent years and the time is now ready to exploit this potential. The exceptional setting during the SARS-CoV-2 pandemic has shown many that new technology is available safely, quickly, and effectively. The emergency has catalyzed innovation processes and shown for post-pandemic time after that we are equipped to tackle the challenges in ophthalmic healthcare - ultimately for the benefit of patients and society.

Paracentral acute middle maculopathy after uneventful ocular surgery with local anaesthetic blocks.

OBJECTIVE: To describe the role of local anaesthetic blocks as a potential cause of paracentral acute middle maculopathy (PAMM) after uneventful ocular surgery. METHODS: Retrospective, observational, international, multicentre case series. Nine cases of PAMM with associated visual loss following uneventful ocular surgery with local anaesthetic blocks were observed in a 9-year period (2011-2020). Demographic, ocular and systemic data, anaesthetic data and surgical details were collected. Visual acuity (VA), fundus photography, fluorescein angiography, optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) images were reviewed. RESULTS: All nine cases were associated with decreased VA at 24 h postoperative check (ranging from hand movement to 20/200). A hyperreflective band within the middle retinal layers was observed in the structural OCT in the acute phase, evolving to thinning and atrophy of the inner retinal layers in sequential follow-up scans performed. Fluorescein angiography showed delayed perfusion in early arterial phase with normal perfusion in late venous phases. OCTA showed decreased perfusion in the deep capillary plexus. Visual recovery was variable between cases during follow-up (ranging from count fingers to 20/20). CONCLUSIONS: A combination of a vasoconstrictive effect of the anaesthetic agent, an intraocular pressure spike and a mechanical effect of the volume of anaesthetic injected may result in decreased retinal artery perfusion and be evidenced as PAMM in OCT scans. PAMM may present as a potential complication of local anaesthetic blocks in cases of unexpected visual loss after uneventful ocular surgery.

Telemedicine in oculoplastic and adnexal surgery: clinicians' perspectives in the UK.

BACKGROUND/AIMS: The COVID-19 has facilitated a paradigm shift in the sphere of ophthalmic telemedicine: its utility is no longer limited to providing care to remote regions, rather it is expeditiously being adopted as the new standard of care. The aim of our paper is to explore the current attitudes of oculoplastic surgeons towards telemedicine and its utility in the present landscape and its prospects in the future. METHODS: A 39-item questionnaire was distributed to consultant oculoplastic surgeons practising across the UK and anonymised responses were collected and analysed. RESULTS: The COVID-19 pandemic has allowed rapid implementation of telemedicine services in oculoplastic departments across the UK with 86.6% of the respondents incorporating telemedicine into the routine clinical practice. Clinicians reported a statistically significant increase in utility of telemedicine, confidence in using telemedicine and quality of infrastructure available to employ telemedicine following the COVID-19 outbreak. The greatest utility of telemedicine is in triaging, postoperative assessment and eyelid lesion assessment. Main barriers to implementation of telemedicine included difficulties in conducting clinical examinations, lack of administrative support and poor access to digital technologies for patients. Overall, most clinicians were satisfied with the impact of telemedicine services and almost all experts foresee themselves continuing to use telemedicine in the future. CONCLUSIONS: Telemedicine has become an integral part of the oculoplastic service delivery since the COVID-19 pandemic its use is likely to continue. Further development of digital infrastructure and improvement of clinical examination capabilities are required to enable its wider adoption.

Emerging therapies and their delivery for treating age-related macular degeneration.

Age-related macular degeneration (AMD) is the most common cause of blindness in the Western world and is characterised in its latter stages by retinal cell death and neovascularisation and earlier stages with the loss of parainflammatory homeostasis. Patients with neovascular AMD (nAMD) are treated with frequent intraocular injections of anti-vascular endothelial growth factor (VEGF) therapies, which are not only unpopular with patients but carry risks of sight-threatening complications. A minority of patients are unresponsive with no alternative treatment available, and some patients who respond initially eventually develop a tolerance to treatment. New therapeutics with improved delivery methods and sustainability of clinical effects are required, in particular for non-neovascular AMD (90% of cases and no current approved treatments). There are age-related and disease-related changes that occur which can affect ocular drug delivery. Here, we review the latest emerging therapies for AMD, their delivery routes and implications for translating to clinical practice.

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.

Visual outcomes and treatment adherence of patients with macular pathology using a mobile hyperacuity home-monitoring app: a matched-pair analysis.

OBJECTIVE: We compared patients with neovascular age-related macular degeneration (nvAMD), diabetic macular oedema (DMO) and other macular pathologies testing their vision with the hyperacuity home-monitoring app Alleye to patients not performing home-monitoring regarding clinical outcomes and clinical management. DESIGN: Matched-pair analysis. SETTING: Retina Referral Centre, Switzerland. PARTICIPANTS: For each eye using Alleye, we matched 2-4 controls not using home-monitoring based on age, gender, number of previous intravitreal injections (IVI), best corrected visual acuity (BCVA) (Early Treatment Diabetic Retinopathy Study letters), central macular thickness (CRT) and time point of enrolment, using the Mahalanobis distance matching algorithm. We included 514 eyes (288 patients); 107 eyes with nvAMD using home monitoring and 218 controls not using home monitoring, 25 eyes with DMO (n=52 controls) and 40 eyes with miscellaneous conditions (n=72 controls). 173 eyes (33.7%) received no IVI during follow-up. MAIN OUTCOME MEASURES: Improvement of ≥5 letters, number of injection visits and treatment retention after correcting for differences in baseline characteristics with multivariate analyses. RESULTS: The mean follow-up duration was 809 days (range 147-1353) and the mean number of IVI/year among treated eyes was 6.7 (SD 3.1). Mean age at baseline was 70.4 years (SD 10.9), BCVA was 77.6 letters (SD 11.6) and CRT was 263.6 µm (SD 86.7) and was similar between patients using and not using home monitoring. In multivariate analyses, patients using home monitoring had a higher chance to improve visual acuity by ≥5 letters (OR 1.67 (95% CI 1.01 to 2.76; p=0.044)) than controls. Treated eyes using home monitoring had less injection visits/year (-0.99 (95% CI -1.59 to -0.40; p=0.001)) and a longer treatment retention +69.2 days (95% CI 2.4 to 136.0; p=0.042). These effects were similar across retinal pathologies. CONCLUSIONS: This data suggest that patients capable of performing mobile hyperacuity home monitoring benefit in terms of visual acuity and discontinue treatment less often than patients not using home monitoring.

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.

Smartphone-based remote monitoring of vision in macular disease enables early detection of worsening pathology and need for intravitreal therapy.

BACKGROUND/AIMS: To assess the outcomes of home monitoring of distortion caused by macular diseases using a smartphone-based application (app), and to examine them with hospital-based assessments of visual acuity (VA), optical coherence tomography-derived central macular thickness (CMT) and the requirement of intravitreal injection therapy. DESIGN: Observational study with retrospective analysis of data. METHODS: Participants were trained in the correct use of the app (Alleye, Oculocare, Zurich, Switzerland) in person or by using video and telephone consultations. Automated threshold-based alerts were communicated based on a traffic light system. A 'threshold alarm' was defined as three consecutive 'red' scores, and turned into a 'persistent alarm' if present for greater than a 7-day period. Changes of VA and CMT, and the requirement for intravitreal therapy after an alarm were examined. RESULTS: 245 patients performing a total of 11 592 tests (mean 46.9 tests per user) were included and 85 eyes (164 alarms) examined. Mean drop in VA from baseline was -4.23 letters (95% CI: -6.24 to -2.22; p<0.001) and mean increase in CMT was 29.5 µm (95% CI: -0.08 to 59.13; p=0.051). Sixty-six eyes (78.5%) producing alarms either had a drop in VA, increase in CMT or both and 60.0% received an injection. Eyes with persistent alarms had a greater loss of VA, -4.79 letters (95% CI: -6.73 to -2.85; p<0.001) or greater increase in CMT, +87.8 µm (95% CI: 5.2 to 170.4; p=0.038). CONCLUSION: Smartphone-based self-tests for macular disease may serve as reliable indicators for the worsening of pathology and the need for treatment.

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.

Accuracy of periocular lesion assessment using telemedicine.

OBJECTIVES: To assess the agreement in diagnosis and management plans reached between clinicians reviewing eyelid lesions remotely and in face-to-face clinics. METHODS: In this single-centre observational case series, data were prospectively collected on 50 consecutive adults referred with eyelid lesions suitable to be seen by a nurse. A proforma was completed to gather salient information. A nurse specialist saw patients in face-to-face clinics and collected information using the proforma, devising a diagnosis and management plan. Photographs of the eyelid lesions were taken by a medical photographer. A subsequent remote review was completed by an oculoplastic consultant using the proforma information and photographs in the absence of the patient. The diagnosis and management plan constructed by the nurse specialist were compared with those reached by the consultant. RESULTS: Complete data were available for 44 consecutive cases. There was an overall 91% agreement (40 cases out of 44) between the diagnoses reached by the nurse specialist, and the remote reviewer; kappa coefficient 0.88 (95% CI 0.76 to 0.99). There was an overall 82% agreement (36 out of 44 cases) in the management plans devised by the nurse-led clinic and remote reviewer; kappa coefficient 0.74 (95% CI 0.58 to 0.90). The average time taken for a remote reviewer to reach a diagnosis and management plan was 1 min and 20 s. CONCLUSIONS: This study evaluated the feasibility of assessing eyelid lesions using asynchronous telemedicine. There was overall a high rate of concordance in the diagnosis reached, and management devised between the clinic and remote review.

False alarms and the positive predictive value of smartphone-based hyperacuity home monitoring for the progression of macular disease: a prospective cohort study.

BACKGROUND: Home monitoring of hyperacuity allows early detection of progression in exudative neovascular age-related macular degeneration (nvAMD) and diabetic macular oedema (DMO). However, false alarms may pose a significant burden to both patients and healthcare professionals alike. PURPOSE: To assess the false alarm rate and positive predictive value of smartphone-based home monitoring of nvAMD and DMO. METHODS: Patients treated with anti-angiogenic therapy in a pro re nata scheme for nvAMD or DMO at the Medical Retina service (Lucerne, Switzerland) between March and June 2016 were included in this prospective cohort study. The home monitoring test Alleye (Oculocare Ltd, Switzerland) provided a session score from 0-100 in addition to a traffic-light system feedback via the smartphone application. Three consecutive "red" scores were considered as a positive test or alarm signal. Specificity, 1-specificity (false alarm rate) and the predictive value for optical coherence tomography-based disease progression were analysed. RESULTS: 73 eyes of 56 patients performed 2258 tests in 222 "follow-up periods". Progression was observed in 141 periods (63.5%). The specificity of the test was 93.8% (95% CI: 86.2-98.0%), the false alarm rate 6.1% (95% CI: 2.0-13.8%), and the positive predictive value 80.0% (95% CI: 59.3-93.2%) for the detection of progression. CONCLUSION: False alarm rates for the detection of progression in macular disease via home monitoring is low. These findings suggest that home monitoring may be a useful adjunct for remote management of nvAMD and DMO.
