Acute Lagophthalmos due to Bell's Palsy could be a Sign of COVID-19.

We sought to investigate whether lagophthalmos was associated with coronavirus infection (COVID-19). Patients diagnosed with lagophthalmos in 2019 were included in group one (n = 9), while those diagnosed with lagophthalmos in 2020 were included in group two (n = 33). With the onset of COVID-19, we observed that the number of patients seen with lagophthalmia increased compared with the same period from the previous year. To confirm this, reverse transcriptase-polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 test results were followed in patients with suspicious findings, after which blood test results were compared. The reported lagophthalmos cases increased by 367% in 2020 compared with 2019. Additionally, the mean white blood cell, lymphocyte and platelet counts of patients in group two were all significantly decreased compared with group one. Lagophthalmos due to Bell's palsy could be a sign of COVID-19.
