This rare complication of perforation is more common in children. The injured eye remains markedly inflamed and the wound might have been cleaned inadequately or too late. Over a period of two weeks to several months or even years a particular type of inflammatory response begins in the uvea and subsequently a similar reaction occurs in the other eye. The inflammation in both eyes can be so severe as to cause blindness. The condition does, however, respond well to steroid treatment and it is extremely rare. Occasionally, one sees patients who have an artificial eye complaining of transient blurring of the vision of their remaining eye. They need to be examined carefully for signs of uveitis.
