Diabetic retinopathy is independently associated with increased risk of intubation: A single centre cohort study of patients with diabetes hospitalised with COVID-19.

In our study of 187 patients with diabetes hospitalised with COVID-19 we observed a more than 5 fold increased risk of intubation in patients with diabetic retinopathy. Further studies are required to understand the mechanisms that explain the associations between retinopathy and other indices of microangiopathy with severe COVID-19.
