Seeking clarity on retinal findings in patients with COVID-19
described hyper-reflective lesions in ganglion cell and inner plexiform layers on optical coherence tomography (OCT) images from 24 eyes of 12 adults who had symptoms of COVID-19. Marinho and colleagues argued that these lesions could be associated with COVID-19-related neurological events in humans.
On the basis of the fundamental principles of OCT, we hold different views as to how the hyper-reflective foci were generated and their relevance to COVID-19.
,
Therefore, all hyper-reflective lesions marked out by Marinho and colleagues by arrows in the figure of their Correspondence
can be adequately explained by normal retinal blood vessels extending into the ganglion cell and inner plexiform layers.
should provide further elaborate analysis and scientific comparison to confirm the hyper-reflective characteristics of the retinas and their conclusion.
We declare no competing interests.
