• W4386400799 abstract "Purpose The purpose of the study is to observe the characteristics of ocular manifestations in coronavirus disease 2019 (COVID-19) patients and to analyze the presence of severe acute respiratory syndrome coronavirus 2 ribonucleic acid (SARS-CoV-2 RNA) in the tears of patients with moderate-to-severe COVID-19. Material and methods We conducted this prospective cross-sectional study from February to June 2021 at the All India Institute of Medical Sciences, one of the tertiary eye care centers in Nagpur, India. The study included confirmed COVID-19 patients based on real-time reverse transcription-polymerase chain reaction (RT-PCR) nasopharyngeal swabs, whether or not the patients exhibited ocular symptoms. We recorded detailed information regarding the patients’ history, including demographic profile, ocular symptoms, systemic symptoms, and radiologic findings. We collected ocular samples within 48 hours of collecting naso-oropharyngeal samples from the patients’ eyes. We used conjunctival swabs to obtain tear samples, which we then placed in viral transport media (VTM) for cold chain transportation to the microbiology department. We performed RT-PCR on the tear samples to detect the presence of the SARS-CoV-2 virus. Result We included 40 patients in the study, with 26 (65%) classified as having moderate COVID-19, six (15%) classified as having severe COVID-19, and the remaining having mild COVID-19. Out of the 40 patients, five (12%) tested positive for SARS-CoV-2 in the tear sample using RT-PCR, seven (17%) exhibited ocular signs and symptoms, and only one tested positive for SARS-CoV-2 in their tears. The ocular manifestations observed in COVID-19 patients included dry eye, conjunctivitis (including conjunctival hyperemia and epiphora), and lid edema. Notably, we detected a positive COVID-19 tear sample in patients both with and without ocular symptoms. Conclusion Limited reports have focused on ocular involvement in patients with COVID-19. However, our study demonstrates the detection of SARS-CoV-2 in conjunctival swabs from confirmed COVID-19 patients, albeit with a lower positivity rate. Despite the low prevalence of the virus found in tears, there is a potential risk of transmission through ocular routes. It is noteworthy that we observed a COVID-19-positive tear sample in patients with and without ocular symptoms. Therefore, it is important to consider the possibility of ocular transmission even in the absence of ocular manifestations. Medical personnel should take careful precautions during ocular examinations of patients diagnosed with COVID-19 to minimize the risk of transmission." @default.
