“…A similar study was performed for the Peek Acuity application. 22 This study tested 111 children, ages 3-17 and compared visual acuity from Peek Acuity to clinic protocol visual acuity and showed a good ICC for first (0.88) and second (0.84) eyes tested; though the ICC dropped for second eyes (0.45) in children aged 3-5. We did not test for this variable.…”

: Purpose With the recent rise of teleophthalmology due to coronavirus disease, we are in need of accurate and reliable methods of checking visual acuity remotely. We compare the visual acuity as measured by the GoCheck Kids application, HOTV with the amblyopia treatment study (ATS), and our clinic protocol. Design This is a prospective, comparison of visual acuity assessment methods. Methods Established patients (aged 3-18) in the practice of a single pediatric ophthalmologist were eligible. Visual acuity was measured by: 1) GoCheck Kids mobile application (by patient’s family member), 2) HOTV-ATS (by study personnel), and 3) regular clinic protocol (by ophthalmic technician). To assess agreement between measures of acuity, intraclass correlations with 95% confidence intervals were computed. Results Fifty-three children participated. The mean difference between GoCheck Kids and HOTV-ATS acuities (0.094) was significantly different (p<0.001); the intraclass correlation (ICC) was 0.55 (95% CI: 0.40, 0.68). The mean difference between GoCheck Kids and chart acuities (0.010) was not significantly different (p=0.319); ICC: 0.59 (95% CI: 0.45, 0.71). The mean difference between HOTV-ATS and chart acuities (0.084) was significantly different (p<0.001); ICC: 0.66 (95% CI: 0.53, 0.76). The percent of eyes with visual acuity as measured by GoCheck Kids that was within 1 line of the HOTV-ATS and chart acuity was 65.3% and 86.7%, respectively. Conclusions GoCheck Kids as checked by a family member provides a modest correlation of visual acuity compared to the chart screen and a fair correlation of visual acuity compared to HOTV-Amblyopia Treatment Study protocol, though a vast majority are within 1 line.

“…Obtaining a high-quality neuro-ophthalmology examination is critical to telehealth adoption. Presently, validated mobile applications for components of the neuro-ophthalmic examination are available for visual acuity (PEEK Acuity and Vision@home) ( 42 , 43 ), color vision (EyeHandbook) ( 44 ), and visual fields ( 45 ). Mobile applications can measure torsion ( 46 ) and are in development for measuring esotropia ( EyePhoneDevices.com ) and heterophorias (L. Sun and J. Odell, personal communication, April 4, 2020).…”

Background: Telehealth provides health care to a patient from a provider at a distant location. Before the COVID-19 pandemic, adoption of telehealth modalities was increasing slowly but steadily. During the public health emergency, rapid widespread telehealth implementation has been encouraged to promote patient and provider safety and preserve access to health care. Evidence Acquisition: Evidence was acquired from English language Internet searches of the medical and business literature and following breaking news on the COVID-19 pandemic and responses from health care stakeholders, including policymakers, payers, physicians, health care organizations, and patients. We also had extensive discussions with colleagues who are developing telehealth techniques relevant to neuro-ophthalmology. Results: Regulatory, legal, reimbursement, and cultural barriers impeded the widespread adoption of telehealth before the COVID-19 pandemic. With the increased use of telehealth in response to the public health emergency, we are rapidly accumulating experience and an evidence base identifying opportunities and challenges related to the widespread adoption of tele-neuro-ophthalmology. One of the major challenges is the current inability to adequately perform funduscopy remotely. Conclusions: Telehealth is an increasingly recognized means of health care delivery. Tele-Neuro-Ophthalmology adoption is necessary for the sake of our patients, the survival of our subspecialty, and the education of our trainees and students. Telehealth does not supplant but supplements and complements in-person neuro-ophthalmologic care. Innovations in digital optical fundus photography, mobile vision testing applications, artificial intelligence, and principles of channel management will facilitate further adoption of tele-neuro-ophthalmology and bring the specialty to the leading edge of health care delivery.

“…Access and use of digital photography, including in LMIC, is increasing. The use of smartphones has largely contributed to this, particularly in eye care [9][10][11]. In medicine, photographic data increasingly forms part of patients' medical records.…”

Remote monitoring of clubfoot treatment with digital photographs in low resource settings: Is it accurate?

Background Clinical examination and functional assessment are often the first steps to assess outcome of clubfoot treatment. Clinical photographs may be an adjunct used to assess treatment outcomes in lower resourced settings where physical review by a specialist is limited. We aimed to evaluate the diagnostic performance of photographic images of patients with clubfoot in assessing outcome following treatment. Methods In this single-centre diagnostic accuracy study, we included all children with clubfoot from a cohort treated between 2011 and 2013, in 2017. Two physiotherapists trained in clubfoot management calculated the Assessing Clubfoot Treatment (ACT) score for each child to decide if treatment was successful or if further treatment was required. Photographic images were then taken of 79 feet. Two blinded orthopaedic surgeons assessed three sets of images of each foot (n = 237 in total) at two time points (two months apart). Treatment for each foot was rated as 'success', 'borderline' or 'failure'. Intra-and inter-observer variation for the photographic image was assessed. Sensitivity, specificity, positive and negative predictive values were calculated for the photographic image compared to the ACT score. Results There was perfect correlation between clinical assessment and photographic evaluation of both raters at both time-points in 38 (48%) feet. The raters demonstrated acceptable reliability with re-scoring photographs (rater 1, k = 0.55; rater 2, k = 0.88). Thirty percent (n = 71) of photographs were assessed as poor quality image or sub-optimal patient position.
