Role of augmented reality and virtual reality from the Indian healthcare education perspective - A systematic review

Augmented reality (AR) and virtual reality (VR), are upcoming technologies with considerable potential to revolutionizing healthcare education, enhancing patient safety, and improving healthcare quality particularly in the Indian context. This review is conducted to view the current scenario of Indian context considering the impact of COVID-19. The current systematic review study was done following PRISMA 2020 guidelines using the key terms "Augmented Reality," "Virtual Reality," "Healthcare," and "India." Only the PubMed database was selected based on its reputation and authenticity, which is the only limitation of this study and strength. Both qualitative and quantitative methods are used for synthesis of results. In Indian context, 12 (1.7%) and 36 (2.2%) articles related to AR and VR were found, respectively. Six abstracts could not be retrieved, and after screening abstracts, three were found not suitable in VR and eight were found duplicate. A total of 30 articles were considered for this review. 18 (50%) were original, 12 (33.3%) were review, and 6 (16.7%) were other articles. 03 (8.3%), 21 (58.3%), and 12 (33.3%) articles were related to AR, VR, and both AR and VR, respectively. Considering the single database search and six unretrievable abstract, AR, VR, mixed reality (MR), soft e-skin, and extended reality (XR) technologies have the potential to revolutionize healthcare education and training, reducing real-life errors and improving patient safety. Although the Indian healthcare sector only contributes 1.7-2.2% to PubMed publications related to AR and VR.. The review was not registered.

Remote Perimetry in a Virtual Reality Metaverse Environment for Out-of-Hospital Functional Eye Screening Compared Against the Gold Standard Humphrey Visual Fields Perimeter: Proof-of-Concept Pilot Study

BACKGROUND

The growing global burden of visual impairment necessitates better population eye screening for early detection of eye diseases. However, accessibility to testing is often limited and centralized at in-hospital settings. Furthermore, many eye screening programs were disrupted by the COVID-19 pandemic, presenting an urgent need for out-of-hospital solutions.

OBJECTIVE

This study investigates the performance of a novel remote perimetry application designed in a virtual reality metaverse environment to enable functional testing in community-based and primary care settings.

METHODS

This was a prospective observational study investigating the performance of a novel remote perimetry solution in comparison with the gold standard Humphrey visual field (HVF) perimeter. Subjects received a comprehensive ophthalmologic assessment, HVF perimetry, and remote perimetry testing. The primary outcome measure was the agreement in the classification of overall perimetry result normality by the HVF (Swedish interactive threshold algorithm-fast) and testing with the novel algorithm. Secondary outcome measures included concordance of individual testing points and perimetry topographic maps.

RESULTS

We recruited 10 subjects with an average age of 59.6 (range 28-81) years. Of these, 7 (70%) were male and 3 (30%) were female. The agreement in the classification of overall perimetry results was high (9/10, 90%). The pointwise concordance in the automated classification of individual test points was 83.3% (8.2%; range 75%-100%). In addition, there was good perimetry topographic concordance with the HVF in all subjects.

CONCLUSIONS

Remote perimetry in a metaverse environment had good concordance with gold standard perimetry using the HVF and could potentially avail functional eye screening in out-of-hospital settings.

Metaverse and Virtual Health Care in Ophthalmology: Opportunities and Challenges

ABSTRACT

The outbreak of the coronavirus disease 2019 has further increased the urgent need for digital transformation within the health care settings, with the use of artificial intelligence/deep learning, internet of things, telecommunication network/virtual platform, and blockchain. The recent advent of metaverse, an interconnected online universe, with the synergistic combination of augmented, virtual, and mixed reality described several years ago, presents a new era of immersive and real-time experiences to enhance human-to-human social interaction and connection. In health care and ophthalmology, the creation of virtual environment with three-dimensional (3D) space and avatar, could be particularly useful in patient-fronting platforms (eg, telemedicine platforms), operational uses (eg, meeting organization), digital education (eg, simulated medical and surgical education), diagnostics, and therapeutics. On the other hand, the implementation and adoption of these emerging virtual health care technologies will require multipronged approaches to ensure interoperability with real-world virtual clinical settings, user-friendliness of the technologies and clinical efficiencies while complying to the clinical, health economics, regulatory, and cybersecurity standards. To serve the urgent need, it is important for the eye community to continue to innovate, invent, adapt, and harness the unique abilities of virtual health care technology to provide better eye care worldwide.

Eye Care During the COVID-19 Pandemic: A Report on Patients' Perceptions and Experiences, an Asian Perspective

INTRODUCTION

To elucidate the perceptions on eye care of patients affected by the disruption of outpatient and surgical ophthalmological services during the COVID-19 pandemic.

METHODS

A cross-sectional questionnaire-based survey was conducted during the reopening of outpatient services at two tertiary eye care centres in Singapore and North India. Consecutive patients were recruited from general and specialist eye clinics in June 2020.

RESULTS

A total of 326 patients were recruited, 200 patients from Singapore and 126 patients from New Delhi, India. The most common eye conditions were diabetic retinopathy and uveitis or ocular inflammatory conditions in the Indian centre, whereas the most common in the Singaporean centre were cataract in the pre- or postoperative stage and glaucoma. For patients from the Indian centre, 61.9% felt that COVID-19 had negatively impacted their eye disease, 58.7% were more distressed by their eye disease, 70.8% could not access appropriate eye care, 66.6% were afraid of contracting COVID-19 in the clinic, and 61.9% were accepting of teleconsultations. For patients from the Singaporean centre, 13.5% felt that COVID-19 had negatively impacted their eye disease, 19.5% were more distressed by their eye disease, 21.5% could not access appropriate eye care, 35% were afraid of contracting COVID-19 in the clinic, and only 31% were accepting of teleconsultations.

CONCLUSION

Patients from India appear to have been more negatively affected by the pandemic compared to patients from Singapore. This study highlights patients' perceptions of the impact of COVID-19 on eye care, perceived risks, ease of access to care and attitudes towards eye care during the pandemic. Patients' perceptions are integral in developing strategies for the best care possible. There were heterogeneous responses amongst our patients; hence, there may be a role for more individualized healthcare strategies in the future.

Virtual Reality Applications in Medicine During the COVID-19 Pandemic: Systematic Review (Preprint)

Background

Virtual reality can play an important role during the COVID-19 pandemic in the health care sector. This technology has the potential to supplement the traditional in-hospital medical training and treatment, and may increase access to training and therapies in various health care settings.

Objective

This systematic review aimed to describe the literature on health care–targeted virtual reality applications during the COVID-19 crisis.

Methods

We conducted a systematic search of the literature on the PsycINFO, Web of Science, and MEDLINE databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The search string was as follows: “[(virtual reality)] AND [(COVID-19) OR (coronavirus) OR (SARS-CoV-2) OR (healthcare)].” Papers published in English after December 2019 in peer-reviewed journals were selected and subjected to the inclusion and exclusion criteria. We used the Mixed Methods Appraisal Tool to assess the quality of studies and the risk of bias.

Results

Thirty-nine studies met the inclusion criteria. Seventeen studies showed the usefulness of virtual reality during the COVID-19 crisis for reducing stress, anxiety, depression, and pain, and promoting physical activity. Twenty-two studies revealed that virtual reality was a helpful learning and training tool during the COVID-19 crisis in several areas, including emergency medicine, nursing, and pediatrics. This technology was also used as an educational tool for increasing public understanding of the COVID-19 pandemic. Different levels of immersion (ie, immersive and desktop virtual reality), types of head-mounted displays (ie, PC-based, mobile, and standalone), and content (ie, 360° videos and photos, virtual environments, virtual reality video games, and embodied virtual agents) have been successfully used. Virtual reality was helpful in both face-to-face and remote trials.

Conclusions

Virtual reality has been applied frequently in medicine during the COVID-19 pandemic, with positive effects for treating several health conditions and for medical education and training. Some barriers need to be overcome for the broader adoption of virtual reality in the health care panorama.

Virtual Reality and Augmented Reality in Ophthalmology: A Contemporary Prospective

PURPOSE

Most published systematic reviews have focused on the use of virtual reality (VR)/augmented reality (AR) technology in ophthalmology as it relates to surgical training. To date, this is the first review that investigates the current state of VR/AR technology applied more broadly to the entire field of ophthalmology.

METHODS

PubMed, Embase, and CINAHL databases were searched systematically from January 2014 through December 1, 2020. Studies that discussed VR and/or AR as it relates to the field of ophthalmology and provided information on the technology used were considered. Abstracts, non-peer-reviewed literature, review articles, studies that reported only qualitative data, and studies without English translations were excluded.

RESULTS

A total of 77 studies were included in this review. Of these, 28 evaluated the use of VR/AR in ophthalmic surgical training/assessment and guidance, 7 in clinical training, 23 in diagnosis/screening, and 19 in treatment/therapy. 15 studies used AR, 61 used VR, and 1 used both. Most studies focused on the validity and usability of novel technologies.

CONCLUSIONS

Ophthalmology is a field of medicine that is well suited for the use of VR/AR. However, further longitudinal studies examining the practical feasibility, efficacy, and safety of such novel technologies, the cost-effectiveness, and medical/legal considerations are still needed. We believe that time will indeed foster further technological advances and lead to widespread use of VR/AR in routine ophthalmic practice.
