Chiasma [kahy-az-muh]
Chiasma is the place where 2 structures or 2 lines of thought intersect.
In biology, it is where 2 chromosomes attach and exchange genetic material. In anatomy, it is where the optic nerves from 2 eyes cross inside the brain. In literature, it is when 2 ideas meet and create conceptual combinations.
And here… it is where passion for eye care and a love of philosophy come together.
