Purpose: The objective of this study was to identify and validate smartphone-based visual acuity (VA) apps that can be used in a teleophthalmology portal. Methods: The study was conducted in three phases: A survey to investigate if the SmartOptometry App was easy to download, understand and test (phase I), an in-clinic comparison of VA measured in a random testing order with four tools namely COMPlog, Reduced Snellen near vision, Peek Acuity (Distance VA) and SmartOptometry (Near VA) (phase II) and a repeatability study on these 4 tools by measuring VA again (phase III). The study recruited the employees of our institute and adhered to the strict COVID-19 protocols of testing. Results: Phase I Survey ( n = 40) showed 90% of participants used android phones, 60% reported that instructions were clear, and all users were able to self-assess their near VA with SmartOptometry App. Phase II ( n = 68) revealed that Peek Acuity was comparable to COMPlog VA ( P = 0.31), however SmartOptometry was statistically significantly different (within 2 log MAR lines) from Reduced Snellen near vision test, particularly for young ( n = 44, P = 0.004) and emmetropic ( n = 16, P = 0.04) participants. All the 4 tests were found to be repeatable in phase III ( n = 10) with a coefficient of repeatability ≤0.14. Conclusion: Smartphone-based apps were easy to download and can be used for checking patient's distance and near visual acuity. An effect of age and refractive error should be considered when interpreting the results. Further studies with real-time patients are required to identify potential benefits and challenges to solve.

Objective: The aim of this study was to assess the ocular morbidity due to delayed presentation in glaucoma patients because of COVID lockdown. Methodology: This was a retrospective study of 15 cases presented to us between October 2020 and February 2021. Cause of glaucoma in our study group was either primary angle closure, pseudoexfoliation, lens-induced glaucoma, or neovascular glaucoma. The cause of delayed presentation was identified and patients were treated with antiglaucoma medications, Nd-Yag laser, and surgery as per the standard treatment protocol. Results: With both medical and surgical intervention, some useful vision was restored in five cases while in rest it was not salvageable. The vision in the affected eye ranged from 6/60 in Snellen’s chart to perception of light and projection of rays positive. Better results were achieved in angle, closure, and lens-induced glaucoma cases as compared to neovascular glaucoma cases. Conclusion: The time of presentation in such cases is as important as the etiopathogenesis. We are left with limited treatment options if the presentation is late. The lockdown ended but it unraveled quite a few instances of disease presentation which were totally preventable under normal circumstances. Introspection on finding out newer and proactive methods to reach people suffering from such irreversible but preventable diseases is the need of the day especially when preventable but irreversible diseases like glaucoma are considered.

“…Aiming to high-quality, cost-effective care to achieve the appropriate balance between clinical, economic and humanistic objectives, telemedicine is needed due to insufficient drug or intervention methods as presented in Delgrado et al [ 70 ]. In LVPEI Glaucoma Epidemiology and Molecular Genetic Study, a rural population-based study, teleophthalmoscopic grading of peripheral anterior chamber depth with Van Herick (vH) technique showed that combined vH grading and ocular biometry increased the predictability of a gonioscopically occludable angle [ 71 ].…”

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.
