Eyeball Licking: A Dangerous New Trend?

Dangerous Trends for Youth

Caught Red Eyed

While we all hope our children know not to try every new fad that comes along, all children make mistakes. It is important to talk openly with your teens about the risks associated with the dangerous trends among the youth. Be observant, paying attention to your child's behavior and appearance. If you notice any sign of a possible eye infection (whether contracted naturally or not) or if you know or suspect that your teen has participated in eye licking, contact your optometrist immediately to schedule an appointment for a full evaluation.

In the summer of 2013, news spread quickly about a dangerous new trend, called "worming" or oculolinctus, and a serious outbreak of disease among Japanese youth. Upon further investigation, many news sources retracted or amended previously published stories, saying the stories of a sudden increase in illness were only a hoax. In popular culture and social media, however, eyeball licking has earned a prominent presence; a quick internet search reveals that - rumor or not - this new fad has in fact caught on in both the east and the west.

The act of eyeball licking is what it sounds like - licking another person’s eyeball. While children participate in any number of fads on dares or to fit in, this trend carries a number of serious health risks. By spreading the bacteria from one person's mouth to another's eye, "worming" can result in a number of serious infections and even blindness.

•    Pink Eye or Conjunctivitis - Pink eye is highly contagious and common among children. It can be caused by both a viral and bacterial infection of the eye. Symptoms include: itching, redness, inflammation, and watery discharge (viral) or green/yellow discharge (bacterial).

•    Herpes - Oculolinctus can easily spread the highly contagious herpes virus from one person's mouth (cold sores) to another's eye. Present in an eye, the herpes virus can lead to scarring of the cornea and eventually blindness.

•    Corneal Ulcers - A corneal ulcer is an open sore on the outer layer of the cornea. Fungi, bacterial infections, and parasites normally cause corneal ulcers. The rough surface of a tongue, however, can easily scratch and infect the delicate surface of an eye leading to blurred vision, a bloodshot eye, pain, itching, watery discharge, and a white patch on the cornea. Minor abrasions can be treated with antibiotic drops, but a more serious abrasion might result in the need for a corneal transplant.

Talk to your teens. Find out whether they have heard about "worming," know someone who has tried it, or whether they already have. To stop this dangerous trend from spreading, inform your children about the serious, irreversible risks associated with eyeball licking.
