A California electrician developed star-shaped cataracts after being shocked by 14,000 volts of electricity. The current passed through his entire body, including the optic nerve that connects the back of the eye to the brain. “The optic nerve is similar to any wire that conducts electricity,” said Dr Bobby Korn, associate professor of clinical ophthalmology, University of California. “The extreme current and voltage that passed through this important natural wire caused damage to the optic nerve itself.” In animal studies, damage to the eye’s lens from electricity first appears as small bubbles called ‘vacuoles’ on the outside of the lens. These then coalesce to form a star-shaped cataract.
