Readers react to a rare visual disorder, microplastics in arteries and more

Let’s face it

Scientists re-created the demonic distortions that a patient with prosopometamorphopsia, or PMO, sees when looking at faces, Anna Gibbs reported in “Here’s what faces can look like to people with a rare visual disorder” (SN: 4/20/24, p. 32).

Reader John Henderson asked whether research on facial blindness could help scientists better understand PMO.

The two disorders have been linked to similar regions in the brain, including the right occipital lobe and fusiform face area, says neurologist Jason Barton of the University of British Columbia in Vancouver. So studying one disorder could help illuminate the other.
