Oslo University Hospital (OUS) has issued an urgent appeal to the current graduating class of students (russ), urging them to deactivate all laser equipment immediately. This follows a string of incidents where students have suffered serious, potentially permanent eye injuries linked to laser exposure during festive gatherings.
On Friday, the hospital treated another student for severe eye damage suspected to be caused by laser light. Medical staff have also received a referral for a patient from another part of the Helse Sør-Øst region with similar injuries. These cases are described as unusual, fueling concerns that the injuries are directly tied to the use of high-intensity lasers mounted on party buses.
The Risk of Permanent Vision Loss
Medical experts emphasize that even a few milliseconds of exposure to these lasers can cause lasting damage to the central vision. According to Professor Morten C. Moe, head of the eye department at OUS, the damage can result in a permanent weakening or total loss of the ability to see clearly from the center of the eye.
As the region enters a weekend likely to involve extensive celebrations, hospital staff are highlighting the severity of these consequences. While the hospital has declined to identify specific locations or individuals involved due to privacy concerns, they maintain that the frequency of these injuries over a short period is alarming.
Regulatory and Enforcement Outlook
While some event organizers, such as those hosting the gathering at Kadettangen in Bærum, have proactively banned laser use, police enforcement remains decentralized. Police operations leader Bjørn Gunnar Nysæter stated that while the force is aware of the issue, no specific, separate controls for lasers have been implemented. Instead, the issue may be treated as one of many technical inspection points for vehicles.
Moving forward, the situation could lead to stricter scrutiny of party bus modifications. As the Directorate for Radiation Protection and Nuclear Safety (DSA) continues its examination of seized equipment, the gathered data may eventually inform broader safety guidelines for public events. For now, medical professionals remain focused on the immediate goal of preventing further life-altering injuries.
