retiform

On Wednesday, researchers from New York published a series of case studies that, they said, “add to a growing body of literature supporting livedo racemosa and retiform purpura as cutaneous findings in patients with COVID-19.”

Livedo racemosa is persistent discoloration of the skin, while retiform purpura consists of skin lesions.

Retiform, rē′ti-form, adj. having the form or structure of a net.

The impressions, ‘laid up in the brain, will be reversed back to the retiform coat and crystalline humour,’ hence ‘a lively seeing, as if, de novo, the object had been placed before the eye’. 

Retina, a retiform expansion of the sensatory nerves, which receives the impression that gives rise to vision, or visual perception.
