Switzerland: Boy injures self with 150 mW pointer

A 15-year-old Swiss boy severely damaged his vision after aiming the beam from a 150 mW green laser pointer at a mirror, and then reflecting it into his eyes multiple times to “create a ‘laser show’”. He suffered immediate blurred vision.

An examination two weeks later showed injuries to both retinas. There was severe vision loss in the left eye and 20/50 vision in the right. His left eye was injected with ranibizumab which helped improve vision to 20/25 after four weeks. The right eye improved on its own to 20/32.

The left eye clearly shows damage from a self-inflicted exposure to a 150 mW green laser pointer.

The report appeared in a letter published September 9 2010 in the New England Journal of Medicine.
