We designed this study to examine whether COVID-19 infection could lead to retinal and choroidal microvascular involvement in school-age children (6-18 years) in a pandemic peak in China.

Full description

Eighty children with COVID-19 infection were included in the case group. Controls without COVID-19 infection were matched to COVID-19 infection cases by a ratio of 1:4 using frequency matching on age and gender. The primary end point of this study is the retinal and choroidal microvascular changes in school-age children during the COVID-19 pandemic. Secondary endpoint is the
