Teleophthalmology through handheld mobile devices: a pilot study in rural Nepal

The Benefits and Challenges of Implementing Teleophthalmology in Low-Resource Settings: A Systematic Review

Technology has significantly changed medical practice, including diagnosis, treatment, and availability. Telemedicine use in the specialty of ophthalmology seems to be a promising field. In underserved populations, limited coverage of ophthalmic healthcare facilities results in a higher burden of eye-related diseases and visual impairment. The main obstacle preventing these individuals from receiving eye care consultations is difficulty in access and transportation. There is an urgent need for eye care facilities for these people, and teleophthalmology has the potential to provide eye care facilities to these underserved people. Teleophthalmology was reported as cost-effective, time-saving, reliable, and efficient for underserved populations. However, teleophthalmology has certain limitations in its implementation in the form of a high initial cost of equipment, problems with consistent electricity and internet supply, and the reluctance of people in certain regions toward acceptance of teleophthalmology. This systematic review assessed the benefits and challenges of implementing teleophthalmology in low-resource settings.

Evaluating the Efficacy of Teleophthalmology in Delivering Ophthalmic Care to Underserved Populations: A Literature Review

Technological advancement has brought commendable changes in medicine, advancing diagnosis, treatment, and interventions. Telemedicine has been adopted by various subspecialties including ophthalmology. Over the years, teleophthalmology has been implemented in various countries, and continuous progress is being made in this area. In underserved populations, due to socioeconomic factors, there is little or no access to healthcare facilities, and people are at higher risk of eye diseases and vision impairment. Transportation is the major hurdle for these people in obtaining access to eye care in the main hospitals. There is a dire need for accessible eye care for such populations, and teleophthalmology is the ray of hope for providing eye care facilities to underserved people. Numerous studies have reported the advantages of teleophthalmology for rural populations such as being cost-effective, timesaving, reliable, efficient, and satisfactory for patients. Although it is being practiced in urban populations, for rural populations, its benefits amplify. However, there are certain obstacles as well, such as the cost of equipment, lack of steady electricity and internet supply in rural areas, and the attitude of people in certain regions toward acceptance of teleophthalmology. In this review, we have discussed in detail eye health in rural populations, teleophthalmology, and its effectiveness in rural populations of different countries.

The most expressed challenge was inadequate technical facilities (lack of electricity and internet) and rugged geographical distribution, which makes transportation difficult in hilly and mountain areas. Shortage of skilled workforce and supportive policies were also notable challenges documented. Meanwhile, major opportunities identified were education and training of the students and health practitioners and increasing awareness among the general population.

Conclusion

This review identified various factors associated with the successful implementation of digital health initiatives in Nepal. Our findings may guide the formulation of digital health policy and interventions to improve mass health outcomes using digital health services.

The Prevalence of Glaucoma in the Jirel Ethnic Group of Nepal

Glaucoma is one of the leading causes of blindness worldwide with individuals in Asia disproportionately affected. Using a cross-sectional study design as part of the Jiri Eye Study, we assessed the prevalence of glaucoma in the Jirel population of Nepal and provide new information on the occurrence of glaucoma in south central Asia. Over a four-year period, 2,042 members of the Jirel population, aged 18 years and older, underwent a detailed ocular examination. Glaucoma was diagnosed using the International Society of Geographical and Epidemiological Ophthalmology criteria. The mean (SD) age at exam was 42.3 (16.7) years and 54.1% of the sample was female. In the total sample, the mean (SD) intraocular pressure (IOP) and vertical cup-to-disc ratio (VCDR) was 14.55 (2.42) mmHg and 0.31 (0.15), respectively. The 97.5th and 99.5th percentile for IOP and VCDR was 20 mmHg and 22 mmHg, and 0.7 and 0.8, respectively. The overall prevalence of glaucoma in the population was 2.30% (n = 47). Of these 47 individuals, 37 (78.7%) had primary open angle glaucoma, 6 (12.8%) had primary angle closure glaucoma, and 4 (8.5%) had secondary glaucoma. There was a significant (p = 5.86×10-6) increase in the prevalence of glaucoma with increasing age overall and across glaucoma subtypes. Six individuals with glaucoma (12.8%) were blind in at least one eye. Of the individuals with glaucoma, 93.6% were previously undiagnosed. In individuals aged 40 years or older (n = 1057, 51.4% female), the mean (SD) IOP and VCDR was 14.39 (2.63) mmHg and 0.34 (0.16), respectively, and glaucoma prevalence was 4.16% (n = 44). The prevalence of glaucoma and undiagnosed disease is high in the Jirel population of Nepal. This study will inform strategies to minimize glaucoma-associated burden in Nepal.

Teleophthalmology and Artificial Intelligence As Game Changers in Ophthalmic Care After the COVID-19 Pandemic

The current COVID-19 pandemic has boosted a sudden demand for telemedicine due to quarantine and travel restrictions. The exponential increase in the use of telemedicine is expected to affect ophthalmology drastically. The aim of this review is to discuss the utility, effectiveness and challenges of teleophthalmological new tools for eyecare delivery as well as its implementation and possible facilitation with artificial intelligence. We used the terms: “teleophthalmology,” “telemedicine and COVID-19,” “retinal diseases and telemedicine,” “virtual ophthalmology,” “cost effectiveness of teleophthalmology,” “pediatric teleophthalmology,” “Artificial intelligence and ophthalmology,” “Glaucoma and teleophthalmology” and “teleophthalmology limitations” in the database of PubMed and selected the articles being published in the course of 2015-2020. After the initial search, 321 articles returned as relevant. A meticulous screening followed and eventually 103 published manuscripts were included and used as our references. Emerging in the market, teleophthalmology is showing great potential for the future of ophthalmological care, benefiting both patients and ophthalmologists in times of pandemics. The spectrum of eye diseases that could benefit from teleophthalmology is wide, including mostly retinal diseases such as diabetic retinopathy, retinopathy of prematurity, age-related macular degeneration but also glaucoma and anterior segment conditions. Simultaneously, artificial intelligence provides ways of implementing teleophthalmology easier and with better outcomes, contributing as significant changing factors for ophthalmology practice after the COVID-19 pandemic.

A Review of Ophthalmic Telemedicine for Emergency Department Settings

BACKGROUND

Patients presenting to emergency departments for ophthalmic emergencies benefit from prompt evaluation. However, Few emergency departments (EDs) have ophthalmologists on call, and eye care provided in EDs without ophthalmic services can be inaccurate.

METHODS

We review the current state of ophthalmic telemedical care in EDs and highlight important considerations when implementing telemedicine in this setting.

RESULTS

Telemedicine allows ophthalmologists to work with on-site emergency care providers to interview and examine patients remotely in EDs, enabling proper assessment of patient history, visual acuity, pupils, intraocular pressure, as well as the anterior and posterior segment. To date, patients' perceptions of this new model of care have been largely positive.

DISCUSSION

The use of telemedical consultations for remote evaluation of patients with ophthalmic complaints stands to improve the quality of care provided to patients and extend the reach of remote ophthalmologists. The onset of the COVID-19 pandemic and the risk of in-person care further highlights the potential for telemedicine to augment existing models of emergency care.

Digital ophthalmoscopy: through a non-specialist lens

The ophthalmoscope has been a mainstay for non-specialist physicians to review a range of disorders affecting patient fundi. Its design has remained unchanged since its inception and while relatively easy to operate, gaining mastery of it can prove challenging. Training is limited by its single-user interface with the lack of attachments to augment its design and therefore facilitate skill acquisition. Documentation is variable depending on the competence of the individual to satisfactorily see enough of the fundi, and the accuracy with which they can describe their findings. Several groups have looked to find adaptions to smartphones in order to develop user-friendly and affordable alternative to the traditional ophthalmoscope. A digital solution has the potential to provide greater versatility by enhancing documentation, improved training pathways and facilitating more efficient care, with options for geographically disparate healthcare settings to access teleophthalmology input.

Anterior Segment Imaging Devices in Ophthalmic Telemedicine

Obtaining a clear assessment of the anterior segment is critical for disease diagnosis and management in ophthalmic telemedicine. The anterior segment can be imaged with slit lamp cameras, robotic remote controlled slit lamps, cell phones, cell phone adapters, digital cameras, and webcams, all of which can enable remote care. The ability of these devices to identify various ophthalmic diseases has been studied, including cataracts, as well as abnormalities of the ocular adnexa, cornea, and anterior chamber. This article reviews the current state of anterior segment imaging for the purpose of ophthalmic telemedical care.
