Show Summary Details

Quick Reference

An image of the network of retinal blood vessels that is made visible in one's own eye if light is shone on to the eyeball at an oblique angle from a pinhole close to its surface. The best way of seeing the image is by darkening the room and holding a torch or flashlight against the outer corner of one closed eye, and then moving the torch from side to side. Also spelt Purkyně figure. [Named after the Czech-born German physiologist Johannes E(vangelista) Purkinje (Purkyně) (1787–1869) who discovered it]
