Urgent Virtual Eye Assessments During the COVID-19 Pandemic

A Systematic Review of Teleophthalmology Services Post-COVID-19 Pandemic in New Zealand, the United Kingdom, Australia, the United States of America, and Canada

Background: This systematic review of teleophthalmology services in Australia, the United States of America (USA), Canada, and the United Kingdom (UK) during the COVID-19 pandemic is aimed to evaluate changes in teleophthalmology, comparing them to New Zealand (NZ). Methods: A literature search of electronic databases Scopus, Proquest, PubMed, Embase, Web of Science, Cochrane Library, Google Scholar, and Google was conducted using search terms: telemedicine, ophthalmology, teleophthalmology/teleophthalmology, and COVID/COVID-19/coronavirus/covid-pandemic. Studies describing teleophthalmology services created in response to COVID-19 restrictions from March 1, 2020, to January 31, 2024, were analyzed. Results: Of the articles, 37 describing 29 discrete teleophthalmology services were included. There were 15 services in the USA, seven in the UK, two in Canada, two in Australia, and three in NZ. The models of care in the USA were well described, and teleophthalmology was used for general, external, anterior segment, neuro-ophthalmology, and oculoplastic consults, as well as for grading of fundus images in the emergency department setting. In the UK, teleophthalmology was used for general eye care, oculoplastics, and pediatric ophthalmology. In Australia, teleophthalmology was used for postglaucoma surgery monitoring of Intraocular Pressure. In NZ, teleophthalmology was used for general eye consults and triaging, but no formal models were described. Conclusion: COVID-19 offered a unique opportunity for re-examination and expansion of teleophthalmology services globally. Video-based and home-screening teleophthalmology services are feasible but have limitations. Investing in multidisciplinary and community-based technology partnerships can create more equitable teleophthalmology care models (to complement and, when necessary, replace traditional in-person consults), within existing frameworks, making eye care more accessible and efficient.

Recent developments of telemedicine in glaucoma

PURPOSE OF REVIEW

Telemedicine has an increasingly significant role in the fields of ophthalmology and glaucoma. This review covers recent advancements in the development and optimization of teleglaucoma techniques and applications.

RECENT FINDINGS

Glaucoma monitoring and diagnosis via remote tonometry, perimetry, and fundus imaging have become a possibility based on recent developments. Many applications work in combination with smart devices, virtual reality, and artificial intelligence and have been tested in patient populations against conventional "reference-standard" measurement tools, demonstrating promising results. Of note, there is still much progress to be made in teleglaucoma and telemedicine at large, such as accessibility to internet, broadband, and smart devices, application affordability, and reimbursement for remote services. However, continued development and optimization of these applications suggest that the implementation of remote monitoring will be a mainstay for glaucoma patient care.

SUMMARY

Especially since the beginning of the COVID-19 pandemic, remote patient care has taken on an important role in medicine and ophthalmology. Remote versions of tonometry, perimetry, and fundus imaging may allow for a more patient-centered and accessible future for glaucoma care.
