Krukenberg's spindle is the name given to the pattern formed on the inner surface of the cornea by pigmented iris cells that are shed during the mechanical rubbing of posterior pigment layer of the iris with the zonules that are deposited as a result of the currents of the aqueous humor. The sign was described in 1899 by Friedrich Ernst Krukenberg (1871-1946), who was a German pathologist specialising in ophthalmology.[1]
