Insights on the possibility of SARS-CoV-2 transmission through the eyes

A novel coronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or 2019-nCOV), causing coronavirus disease 2019 (COVID-19), has rapidly spread to most countries and regions worldwide since it broke out at the end of 2019. Epidemic of the virus produces a tremendous pressure on the global health systems. With progressive insight into SARS-CoV-2, the role of eye tissue has attracted wide attention in the spread of COVID-19. Whether SARS-CoV-2 can enter the human body through eyes and cause infection? The fact that unprotected exposure of the eyes to 2019-nCoV might have allowed the virus to infect the body implies that 2019-nCOV can invade eye tissue and set foot in organism. Facing the severe challenge of preventing spread of the COVID-19, combined with the high-risk environment of ophthalmology, it is crucial to investigate ocular tropism of coronavirus. This paper explores the possibility of coronavirus transmission through the eye from aspects of probable mechanisms, clinical cases, detection of coronavirus; and puts forward precautions for ophthalmologists and nurses. Consequently, this review reveals our understanding of ocular tropism of coronavirus and contributes to determining risk of ocular transmission, raising awareness of necessary eye protection among medical workers and reducing further prevalence of SARS-CoV-2.     

Ophthalmology practice during COVID-19 pandemic: A survey of Indian ophthalmologists

Purpose:To assess the ophthalmic practice pattern among ophthalmologists in India amidst the COVID-19 pandemic.Methods:An online questionnaire-based analysis was performed among members of the All India Ophthalmological Society (AIOS) and results were analyzed using SPSS software version 20.Results:A total of 2253 responses were received. The majority of the participants (72.6%) were between 30 and 60 years of age and were into private practice (64.7%). During the lockdown, over one-third of participant ophthalmologists reported not attending any OPD patients, whereas a majority (64%) provided only emergency ophthalmic services. During the COVID-19 pandemic, <15% surgeries were performed compared to the pre-COVID-19 era by 81% of participants, whereas elective surgeries were performed by only 4.3%. The proportion of participants utilizing telemedicine in ophthalmology showed a two-fold rise from the pre-COVID-19 era (21.9%) to the COVID-19 pandemic (46%). Over half of the participants reported following the AIOS guidelines, reducing clinic hours, use of screening questionnaires, minimizing staff, and use of breath shield on a slit lamp as precautionary measures to reduce the exposure. Over 95% of ophthalmologists were satisfied (score > 5/10) by the AIOS guidelines for ophthalmic practice during COVID-19.Conclusion:COVID-19 pandemic has adversely affected the ophthalmic care services across India with telemedicine emerging as a major rescue. The majority of practicing ophthalmologists are satisfied with guidelines provided by AIOS for ophthalmic care during the COVID-19 pandemic and have implemented the same in their setup.
